his study demonstrates that mesenchymal stem cell (MSC) overexpressing Bmi1 exerts antiaging and antiosteoporosis effects. These findings might provide a strategy to enhance the functionality of MSCs for use in therapeutic applications. The results suggest a clinical relevance of Bmi1 in MSCs, for example, upregulation of BMI1 expression in human MSCs by hypoxiccultures or treatment with sonic hedgehog activators, then using them for bone marrow concentrate therapy to enhance MSC potency in antiaging and antiosteoporosis.

The new stem cells migrate to the cavities of the large bones and begin producing healthy, normal blood cells. The type of transplant you receive depends on your disease and the availability of a suitable donor.

Autologous (self-transplant): Your own cells are collected and frozen for later use. Autologous transplants are most commonly performed for lymphomas, multiple myeloma, testicular cancer and leukemia.

Syngeneic (identical twin transplant): Stem cells are donated by an identical twin, which is an ideal donor because of the matching genetic identity between donor and recipient.

Allogeneic (donor transplant): Stem cells are collected from a relative or an unrelated donor whose tissue type matches closely with that of the patient, or from umbilical cord blood. Allogeneic transplants are most commonly done for leukemias and bone marrow or immune system failure diseases.

At Winship, our Bone Marrow Transplant Center treats leukemia, lymphoma, multiple myeloma and plasma cell disorders; sickle cell anemia, testicular cancer and bone marrow failures.

CARLSBAD, Calif.--(BUSINESS WIRE)--

Lineage Cell Therapeutics, Inc. (NYSE American and TASE: LCTX), a clinical-stage biotechnology company developing novel cell therapies for unmet medical needs, announced today that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,286,009, entitled Pluripotent stem cell-derived oligodendrocyte progenitor cells for the treatment of spinal cord injury covering methods for utilizing pluripotent stem cell-derived oligodendrocyte progenitor cells (OPCs) for the treatment of spinal cord injury (SCI). The claimed methods involve injecting OPCs derived from a pluripotent human stem cell line into the SCI site and covers both human embryonic and induced pluripotent stem cell-derived OPCs. The issued patent has a term that expires no earlier than 2036.

The issuance of this patent is an important milestone for the Company because the allowed claims provide valuable, long term protection for novel treatments employing off-the-shelf OPC1 cells designed to improve recovery outcomes following severe spinal cord injury, stated Brian M. Culley, Chief Executive Officer of Lineage. We believe we have one of the largest cell therapy intellectual property portfolios in the biotech industry and will continue to grow and defend our position as a leader in this exciting space.

OPC1 cells are produced by directing the developmental lineage of pluripotent cell lines to generate a proprietary and consistent population of oligodendritic cells. These cells are administered to the patient in an effort to confer post-injury regeneration, which is intended to provide greater motor recovery compared to the current standard of care. With encouraging data already generated from a 25-patient Phase I safety trial, the current focus for the OPC1 program is to introduce commercially-viable improvements to the manufacturing process and to initiate a comparative study later in 2020.

About OPC1

OPC1 is currently being tested in Phase I/IIa clinical trial known as SCiStar, for the treatment of acute spinal cord injuries. OPCs are naturally-occurring precursors to the cells which provide electrical insulation for nerve axons in the form of a myelin sheath. SCI occurs when the spinal cord is subjected to a severe crush or contusion injury and typically results in severe functional impairment, including limb paralysis, aberrant pain signaling, and loss of bladder control and other body functions. The clinical development of the OPC1 program has been partially funded by a $14.3 million grant from the California Institute for Regenerative Medicine. OPC1 has received Regenerative Medicine Advanced Therapy (RMAT) designation for the treatment of acute SCI and has been granted Orphan Drug designation from the U.S. Food and Drug Administration (FDA).

Inside your body, red blood cells are constantly on the move. They deliver oxygen to every tissue in every part of your body. These blood cells also cart away waste. So their work is crucial to your survival. But all that squeezing through tiny vessels is tough on red blood cells. Thats why they last only about four months.

Where do their replacements come from? Stem cells.

These are a very special family of cells. When most other cells divide, the daughter cells look and act exactly like their parents. For example, a skin cell cant make anything but another skin cell. The same is true for cells in the intestine or liver.

Not stem cells. Stem cells can become many different types. That is how an embryo grows from a single fertilized egg into a fetus with trillions of specialized cells. They need to specialize to make up tissues that function very differently, including those in the brain, skin, muscle and other organs. Later in life, stem cells also can replace worn-out or damaged cells including red blood cells.

The remarkable abilities of stem cells make them very exciting to scientists. One day, experts hope to use stem cells to repair or replace many different kinds of tissues, whether injured in accidents or damaged by diseases. Such stem cell therapy would allow the body to heal itself. Scientists have found a way to put specialized cells to work repairing damage, too. Together, these cell-based therapies might one day make permanent disabilities a thing of the past.

One unusual type of stem cell offers special promise for such therapeutic uses. For the recent development of this cell type, Shinya Yamanaka shared the 2012 Nobel Prize in medicine.

Meet the family

Blood stem cells live inside your bones, in what is called marrow. There, they divide over and over. Some of the new cells remain stem cells. Others form red blood cells. Still others morph into any of the five types of white blood cells that will fight infections. Although blood stem cells can become any one of these specialized blood cells, they cannot become muscle, nerve or other types of cells. They are too specialized to do that.

Another type of stem cell is more generalized. These can mature into any type of cell in the body. Such stem cells are called pluripotent (PLU ree PO tint). The word means having many possibilities. And its not hard to understand why these cells have captured the imaginations of many scientists.

Until recently, all pluripotent cells came from embryos. Thats why scientists called them embryonic stem cells. After an egg is fertilized, it divides in two. These two cells split again, to become four cells, and so on. In the first few days of this embryos development, each of its cells is identical to all the others. Yet each cell has the potential to develop into any specialized cell type.

When the human embryo reaches three to five days old, its cells start to realize their potential. They specialize. Some will develop into muscle cells or bone cells. Others will form lung cells or maybe the cells lining the stomach. Once cells specialize, their many possibilities suddenly become limited.

By birth, almost all of a babys cells will have specialized. Each cell type will have its own distinctive shape and function. For example, muscle cells will be long and able to contract, or shorten. Red blood cells will be small and plate-shaped, so they can slip through blood vessels with ease.

Hidden among all of these specialized cells are pockets of adult stem cells. (Yes, even newborns have adult stem cells.) Unlike embryonic stem cells, adult stem cells cannot transform into any and every cell type. However, adult stem cells can replace several different types of specialized cells as they wear out. One type of adult stem cell is found in your marrow, making new blood cells. More types are found in other tissues, including the brain, heart and gut.

Among naturally occurring stem cells, the embryonic type is the most useful. Adult stem cells just arent as flexible. The adult type also is relatively rare and can be difficult to separate from the tissues in which it is found. Although more versatile, embryonic stem cells are both difficult to obtain and controversial. Thats because harvesting them requires destroying an embryo.

Fortunately, recent discoveries in stem cell research now offer scientists a third and potentially better option.

The search for answers

In 2006, Shinya Yamanaka discovered that specialized cells like those in skin could be converted back into stem cells. Working at Kyoto University in Japan, this doctor and scientist induced or persuaded mature cells to become stem cells. He did this by inserting a specific set of genes into the cells. After several weeks, the cells behaved just like embryonic cells. His new type of stem cells are called induced pluripotent stem cells, or iP stem cells (and sometimes iPS cells).

Yamanakas discovery represented a huge leap forward. The iP stem cells offer several advantages over both embryonic and adult stem cells. First, iP stem cells are able to become any cell type, just as embryonic stem cells can. Second, they can be made from any starting cell type. That means they are easy to obtain. Third, in the future, doctors would be able to treat patients with stem cells created from their own tissues. Such cells would perfectly match the others, genetically. That means the patients immune system (including all of its white blood cells) would not attack the introduced cells. (The body often mounts a life-threatening attack against transplanted organs that come from other people because they dont offer such a perfect match. To the body, they seem foreign and a potentially dangerous invader.)

Scientists the world over learned of the technique developed by Yamanaka (who now works at the Gladstone Institutes which is affiliated with the University of California, San Francisco). Many of these researchers adopted Yamanakas procedure to create their own induced pluripotent stem cells. For the first time, researchers had a tool that could allow them to make stem cells from people with rare genetic diseases. This helps scientists learn what makes certain cell types die. Experts can also expose small batches of these diseased cells to different medicines. This allows them to test literally thousands of drugs to find out which works best.

And in the future, many experts hope induced stem cells will be used to replace adult stem cells and the cells of tissues that are damaged or dying.

Therapies take patients and patience

Among those experts is Anne Cherry, a graduate student at Harvard University. Cherry is using induced stem cells to learn more about a very rare genetic disease called Pearson syndrome. A syndrome is a group of symptoms that occur together. One symptom of Pearson syndrome is that stem cells in bone marrow cannot make normal red blood cells. This condition typically leads to an early death.

Cherry has begun to study why these stem cells fail.

She started by taking skin cells from a girl with the disease. She placed the cells in a test tube and added genes to turn them into stem cells. Over several weeks, the cells began to make proteins for which the inserted genes had provided instructions. Proteins do most of the work inside cells. These proteins turned off the genes that made the cells act like skin cells. Before long, the proteins turned on the genes to make these cells behave like embryonic stem cells.

After about three months, Cherry had a big batch of the new induced stem cells. Those cells now live in Petri dishes in her lab, where they are kept at body temperature (37 Celsius, or 98.6 Fahrenheit). The scientist is now trying to coax the induced stem cells into becoming blood cells. After that, Cherry wants to find out how Pearson syndrome kills them.

Meanwhile, the patient who donated the skin cells remains unable to make blood cells on her own. So doctors must give her regular transfusions of blood from a donor. Though life-saving, transfusions come with risks, particularly for someone with a serious disease.

Cherry hopes to one day turn the girls induced stem cells into healthy new blood stem cells and then return them to the girls body. Doing so could eliminate the need for further transfusions. And since the cells would be the girls own, there would be no risk of her immune system reacting to them as though they were foreign.

Sight for sore eyes

At University of Nebraska Medical Center in Omaha, Iqbal Ahmad is working on using stem cells to restore sight to the blind. A neuroscientist someone who studies the brain and nervous system Ahmad has been focusing on people who lost sight when nerve cells in the eyes retina died from a disease called glaucoma (glaw KOH muh).

Located inside the back of the eye, the retina converts incoming light into electrical signals that are then sent to the brain. Ahmad is studying how to replace dead retina cells with new ones formed from induced pluripotent stem cells.

The neuroscientist starts by removing adult stem cells from the cornea, or the clear tissue that covers the front of the eye. These stem cells normally replace cells lost through the wear and tear of blinking. They cannot become nerve cells at least not on their own. Ahmad, however, can transform these cells into iP stem cells. Then, with prodding, he turns them into nerve cells.

To make the transformation, Ahmad places the cornea cells on one side of a Petri dish. He then places embryonic stem cells on the other side. A meshlike membrane separates the two types of cells so they cant mix. But even though they cant touch, they do communicate.

Cells constantly send out chemical signals to which other cells respond. When the embryonic stem cells speak, the eye cells listen. Their chemical messages persuade the eye cells to turn off the genes that tell them to be cornea cells. Over time, the eye cells become stem cells that can give rise to different types of cells, including nerve cells.

When Ahmads team implanted the nerve cells into the eyes of laboratory mice and rats, they migrated to the retina. There, they began replacing the nerve cells that had died from glaucoma. One day, the same procedure may restore vision to people who have lost their sight.

Another approach

In using a bodys own cells to repair injury or to treat disease, stem cells arent always the answer. Although stem cells offer tremendous advances in regenerating lost tissue, some medical treatments may work better without them. Thats thanks to the chemical communication going on between all cells all of the time. In some situations, highly specialized cells can act as a conductor, directing other cells to change their tune.

In 2008, while working at the University of Cambridge in England, veterinary neurologist Nick Jeffery began a project that used cells taken from the back of the nose. But Jeffery and his team were not out to create stem cells. Instead, the scientists used those nasal cells to repair damaged connections in the spinal cord.

The spinal cord is basically a rope of nerve cells that ferry signals to and from the brain and other parts of the body. Injuring the spinal cord can lead to paralysis, or the loss of sensation and the inability to move muscles.

Like Ahmad, some researchers are using stem cells to replace damaged nerve cells. But Jeffery, now at Iowa State University in Ames, doesnt think such techniques are always necessary to aid recovery from spinal injuries. Stem cell transplantation, points out Jefferys colleague, neuroscientist Robin Franklin, is to replace a missing cell type. In a spinal injury, the nerve cells arent missing. Theyre just cut off.

Nerve cells contain long, wirelike projections called axons that relay signals to the next cell. When the spine is injured, these axons can become severed, or cut. Damaging an axon is like snipping a wire the signal stops flowing. So the Cambridge scientists set out to see if they could restore those signals.

Jeffery and his fellow scientists work with dogs that have experienced spinal injuries. Such problems are common in some breeds, including dachshunds. The team first surgically removed cells from the dogs sinuses or the hollow spaces in the skull behind the nose. These are not stem cells. These particular cells instead encourage nerve cells in the nose to grow new axons. These cells help the pooches maintain their healthy sense of smell.

The scientists grew these sinus cells in the lab until they had reproduced to large numbers. Then the researchers injected the cells into the spinal cords of two out of every three doggy patients. Each treated dog received an injection of its own cells. The other dogs got an injection of only the liquid broth used to feed the growing cells.

Over several months, the dogs owners repeatedly brought their pets back to the lab for testing on a treadmill. This allowed the scientists to evaluate how well the animals coordinated their front and hind feet while walking. Dogs that had received the nasal cells steadily improved over time. Dogs that received only the liquid did not.

This treatment did not result in a perfect cure. Nerve cells did reconnect several portions of the spinal cord. But nerve cells that once linked to the brain remained disconnected. Still, these dog data indicate that nasal cells can aid in recovering from a spinal cord injury.

Such new developments in cellular research suggest that even more remarkable medical advancements may be just a few years away. Yamanaka, Cherry, Ahmad, Jeffery, Franklin and many other scientists are steadily unlocking secrets to cellular change. And while you cant teach an old dog new tricks, scientists are finding out that the same just isnt true of cells anymore.

The prognosis for spinal cord injuries varies depending on the severity of the injury. There is always hope of recovering some function with spinal cord injuries. The completeness and location of the injury will determine the prognosis.

There are two levels of completeness in spinal cord injuries which impact the outlook:

Spinal cord injuries in which the patient has not experienced paralysis have the greatest chance of recovery. However, those patients who do experience paralysis still have a remarkable chance that is improving with research every day. The sooner treatments are implemented to strengthen muscles below the level of the spinal cord injury, the better the prognosis.

The first year of recovery is the hardest as the patient is just beginning to adjust to his or her condition. The use of physical and occupational therapy during this time is the key to recovery. The extent of the function fully returning is typically seen in the first two years after the initial injury.

Treatment options vary with each spinal cord injury, but typically include:

Mental health is a huge part of recovery for the spinal cord injury patient. Anxiety and depression are common in spinal cord injury patients. These patients will go through good days, and not so good days.

There may be days where the patient wants to give up completely on treatments, and will wonder if it is all worth it. Keeping up with the mental health of the spinal cord injury patient is incredibly important for the overall recovery. Mental health has been proven to directly relate to physical health.

Having a good support system is incredibly important to the overall outlook of a spinal cord injury patient. Spinal cord injury patients will need both physical and emotional support.

Caregivers should continually provide patients with:

Hematopoietic stem cells (HSCs) are defined as stem cells that have a preference for becoming cells of the blood and immune system, such as white bloodcells, red bloodcells, and platelets. Found in the peripheral blood and bone marrow,hematopoietic stem cells are also present in plentiful supply within the umbilical cord blood of newborn babies.

For the past thirty years, cord blood has been used within transplant medicine, including for the treatment of leukemia and other blood diseases. For most conditions in which a bone marrow or peripheral blood stem cell transplant is an option, a cord blood transplant is a potential alternative.

In this article:

Hematopoietic stem cells(HSCs) are thestem cellsthat repopulate the blood and immune system within humans, via a process known ashaematopoiesis. For this reason, hematopoietic stem cell transplantation, better known as HSCT, can be a promising treatment approach for a wide range of conditions.

The use of human cord blood cells dates back as early as 1974, when it was first proposed that stem cell and progenitor cells were present in human cord blood.By 1983, the use of cord blood as an alternative to bone marrow had been proposed. Five years later in 1988, the first successful cord blood transplant to restore a patients blood and immune system cells took place in France.

In addition to a long history of use within transplant medicine, human cord blood cells are playing a growing role within regenerative medicine. Cord blood stem cells have been induced to develop into neural cells, suggesting that they may represent a potential treatment for neurological conditions, such as Alzheimers, Parkinsons, spinal cord injury, dementia, and related conditions.

Human cord blood cells can also develop into blood vessels, making them promising for the repair of tissues following stroke, coronary heart disease, rheumatic heart disease, congestive heart failure, and congenital heart conditions.

What Are the Benefits of Banking #CordBlood? The main benefit to banking cord blood is it allows parents to preserve stem cells for future medical use. Many parts of the body do not regenerate, so they are at risk of failing https://t.co/3oc4Ai4qef pic.twitter.com/kYy9Ds64ad

It is also interesting to consider the common disease categories treatable with cord blood transplant, as shown in the table below.

There are more than 80 medical conditions for which transplantation of hematopoietic stem cells (including cord blood transplant) is a standard treatment option. Most of these therapies require allogeneic transplants, where the patient must use a genetically-matched cord blood donor. The only exceptions to this are patients who are transplanted for solid tumors or acquired anemias. In these situations, the patient may receive an autologous transplant.

Comprehensive lists of conditions treatable with hematopoietic stem cells are available here and here.

In addition, there is a range of disease categories for which cord blood transplant could represent a viable treatment method in the future. For these conditions, there are still unknown criteria that need to be determined before the cord blood stem cell transplant can become commonplace, such as patient criteria for optimal treatment effectiveness, optimum stem cell quantity for use in transplant, and preferred method of stem cell delivery into the patient, as shown below.

The Central Nervous System

The mature mammalian central nervous system (CNS) is composed of three major differentiated cell types: neurons, astrocytes and oligodendrocytes. Neurons transmit information through action potentials and neurotransmitters to other neurons, muscle cells or gland cells. Astrocytes and oligodendrocytes, collectively called glial cells, play important roles of their own, in addition to providing a critical support role for optimal neuronal functioning and survival. During mammalian embryogenesis, CNS development begins with the induction of the neuroectoderm, which forms the neural plate and then folds to give rise to the neural tube. Within these neural structures there exists a complex and heterogeneous population of neuroepithelial progenitor cells (NEPs), the earliest neural stem cell type to form.1,2 As CNS development proceeds, NEPs give rise to temporally and spatially distinct neural stem/progenitor populations. During the early stage of neural development, NEPs undergo symmetric divisions to expand neural stem cell (NSC) pools. In the later stage of neural development, NSCs switch to asymmetric division cycles and give rise to lineage-restricted progenitors. Intermediate neuronal progenitor cells are formed first, and these subsequently differentiate to generate to neurons. Following this neurogenic phase, NSCs undergo asymmetric divisions to produce glial-restricted progenitors, which generate astrocytes and oligodendrocytes. The later stage of CNS development involves a period of axonal pruning and neuronal apoptosis, which fine tunes the circuitry of the CNS. A previously long-held dogma maintained that neurogenesis in the adult mammalian CNS was complete, rendering it incapable of mitotic divisions to generate new neurons, and therefore lacking in the ability to repair damaged tissue caused by diseases (e.g. Parkinsons disease, multiple sclerosis) or injuries (e.g. spinal cord and brain ischemic injuries). However, there is now strong evidence that multipotent NSCs do exist, albeit only in specialized microenvironments, in the mature mammalian CNS. This discovery has fuelled a new era of research into understanding the tremendous potential that these cells hold for treatment of CNS diseases and injuries.

Neurobiologists routinely use various terms interchangeably to describe undifferentiated cells of the CNS. The most commonly used terms are stem cell, precursor cell and progenitor cell. The inappropriate use of these terms to identify undifferentiated cells in the CNS has led to confusion and misunderstandings in the field of NSC and neural progenitor cell research. However, these different types of undifferentiated cells in the CNS technically possess different characteristics and fates. For clarity, the terminology used here is:

Neural Stem Cell (NSCs): Multipotent cells which are able to self-renew and proliferate without limit, to produce progeny cells which terminally differentiate into neurons, astrocytes and oligodendrocytes. The non-stem cell progeny of NSCs are referred to as neural progenitor cells.

Neural Progenitor Cell: Neural progenitor cells have the capacity to proliferate and differentiate into more than one cell type. Neural progenitor cells can therefore be unipotent, bipotent or multipotent. A distinguishing feature of a neural progenitor cell is that, unlike a stem cell, it has a limited proliferative ability and does not exhibit self-renewal.

Neural Precursor Cells (NPCs): As used here, this refers to a mixed population of cells consisting of all undifferentiated progeny of neural stem cells, therefore including both neural progenitor cells and neural stem cells. The term neural precursor cells is commonly used to collectively describe the mixed population of NSCs and neural progenitor cells derived from embryonic stem cells and induced pluripotent stem cells.

Prior to 1992, numerous reports demonstrated evidence of neurogenesis and limited in vitro proliferation of neural progenitor cells isolated from embryonic tissue in the presence of growth factors.3-5 While several sub-populations of neural progenitor cells had been identified in the adult CNS, researchers were unable to demonstrate convincingly the characteristic features of a stem cell, namely self-renewal, extended proliferative capacity and retention of multi-lineage potential. In vivo studies supported the notion that proliferation occurred early in life, whereas the adultCNS was mitotically inactive, and unable to generate new cells following injury. Notable exceptions included several studies in the 1960s that clearly identified a region of the adult brain that exhibited proliferation (the forebrain subependyma)6 but this was believed to be species-specific and was not thought to exist in all mammals. In the early 1990s, cells that responded to specific growth factors and exhibited stem cell features in vitro were isolated from the embryonic and adult CNS.7-8 With these studies, Reynolds and Weiss demonstrated that a rare population of cells in the adult CNS exhibited the defining characteristics of a stem cell: self-renewal, capacity to produce a large number of progeny and multilineage potential. The location of stem cells in the adult brain was later identified to be within the striatum,9 and researchers began to show that cells isolated from this region, and the dorsolateral region of the lateral ventricle of the adult brain, were capable of differentiating into both neurons and glia.10

During mammalian CNS development, neural precursor cells arising from the neural tube produce pools of multipotent and more restricted neural progenitor cells, which then proliferate, migrate and further differentiate into neurons and glial cells. During embryogenesis, neural precursor cells are derived from the neuroectoderm and can first be detected during neural plate and neural tube formation. As the embryo develops, neural stem cells can be identified in nearly all regions of the embryonic mouse, rat and human CNS, including the septum, cortex, thalamus, ventral mesencephalon and spinal cord. NSCs isolated from these regions have a distinct spatial identity and differentiation potential. In contrast to the developing nervous system, where NSCs are fairly ubiquitous, cells with neural stem cell characteristics are localized primarily to two key regions of the mature CNS: the subventricular zone (SVZ), lining the lateral ventricles of the forebrain, and the subgranular layer of thedentate gyrus of the hippocampal formation (described later).11 In the adult mouse brain, the SVZ contains a heterogeneous population of proliferating cells. However, it is believed that the type B cells (activated GFAP+/PAX6+ astrocytes or astrogliallike NSCs) are the cells that exhibit stem cell properties, and these cells may be derived directly from radial glial cells, the predominant neural precursor population in the early developing brain. NPCs in this niche are relatively quiescent under normal physiological conditions, but can be induced to proliferate and to repopulate the SVZ following irradiation.10 SVZ NSCs maintain neurogenesis throughout adult life through the production of fast-dividing transit amplifying progenitors (TAPs or C cells), which then differentiate and give rise to neuroblasts. TAPs and neuroblasts migrate through the rostral migratory stream (RMS) and further differentiate into new interneurons in the olfactory bulb. This ongoing neurogenesis, which is supported by the NSCs in the SVZ, is essential for maintenance of the olfactory system, providing a source of new neurons for the olfactory bulb of rodents and the association cortex of non-human primates.12 Although the RMS in the adult human brain has been elusive, a similar migration of neuroblasts through the RMS has also been observed.13 Neurogenesis also persists in the subgranular zone of the hippocampus, a region important for learning and memory, where it leads to the production of new granule cells. Lineage tracing studies have mapped the neural progenitor cells to the dorsal region of the hippocampus, in a collapsed ventricle within the dentate gyrus.10 Studies have demonstrated that neurogenic cells from the subgranular layer may have a more limited proliferative potential than the SVZ NSCs and are more likely to be progenitor cells than true stem cells.14 Recent evidence also suggests that neurogenesis plays a different role in the hippocampus than in the olfactory bulb. Whereas the SVZ NSCs play a maintenance role, it is thought that hippocampal neurogenesis serves to increase the number of new neurons and contributes to hippocampal growth throughout adult life.12 Neural progenitor cells have also been identified in the spinal cord central canal ventricular zone and pial boundary15-16, and it is possible that additional regional progenitor populations will be identified in the future.

In vitro methodologies designed to isolate, expand and functionally characterize NSC populations have revolutionized our understanding of neural stem cell biology, and increased our knowledge of the genetic and epigenetic regulation of NSCs.17 Over the past several decades, a number of culture systems have been developed that attempt to recapitulate the distinct in vivo developmental stages of the nervous system, enabling theisolation and expansion of different NPC populations at different stages of development. Here, we outline the commonly used culture systems for generating NPCs from pluripotent stem cells (PSCs), and for isolating and expanding NSCs from the early embryonic, postnatal and adult CNS.

Neural induction and differentiation of pluripotent stem cells: Early NPCs can be derived from mouse and human PSCs, which include embryonic stem cells (ESCs) and induced pluripotent stem cells (iPSCs), using appropriate neural induction conditions at the first stage of differentiation. While these neural differentiation protocols vary widely, a prominent feature in popular embryoid body-based protocols is the generation of neural rosettes, morphologically identifiable structures containing NPCs, which are believed to represent the neural tube. The NPCs present in the neural rosette structures are then isolated, and can be propagated to allow NPC expansion, while maintaining the potential to generate neurons and glial cells. More recently, studies have shown that neural induction of PSCs can also be achieved in a monolayer culture system, wherein human ESCs and iPSCs are plated onto a defined matrix, and exposed to inductive factors.18 A combination of specific cytokines or small molecules, believed to mimic the developmental cues for spatiotemporal patterning in the developing brain during embryogenesis, can be added to cultures at the neural induction stage to promote regionalization of NPCs. These patterned NPCs can then be differentiated into mature cell types with phenotypes representative of different regions of the brain.19-24 New protocols have been developed to generate cerebral organoids from PSC-derived neural progenitor cells. Cerebral organoids recapitulate features of human brain development, including the formation of discrete brain regions featuring characteristic laminar cellular organization.25

Neurosphere culture: The neurosphere culture system has been widely used since its development as a method to identify NSCs.26-29 A specific region of the CNS is microdissected, mechanically or enzymatically dissociated, and plated in adefined serum-free medium in the presence of a mitogenic factor, such as epidermal growth factor (EGF) and/or basic fibroblast growth factor (bFGF). In the neurosphere culture system, NSCs, as well as neural progenitor cells, begin to proliferate in response to these mitogens, forming small clusters of cells after 2 - 3 days. The clusters continue to grow in size, and by day 3 - 5, the majority of clusters detach from the culture surface and begin to grow in suspension. By approximately day seven, depending on the cell source, the cell clusters, called neurospheres, typically measure 100 - 200 m in diameter and are composed of approximately 10,000 - 100,000 cells. At this point, the neurospheres should be passaged to prevent the cell clusters from growing too large, which can lead to necrosis as a result of a lack of oxygen and nutrient exchange at the neurosphere center. To passage the cultures, neurospheres are individually, or as a population, mechanically or enzymatically dissociated into a single cell suspension and replated under the same conditions as the primary culture. NSCs and neural progenitor cells again begin to proliferate to form new cell clusters that are ready to be passaged approximately 5 - 7 days later. By repeating the above procedures for multiple passages, NSCs present in the culture will self-renew and produce a large number of progeny, resulting in a relatively consistent increase in total cell number over time. Neurospheres derived from embryonic mouse CNS tissue treated in this manner can be passaged for up to 10 weeks with no loss in their proliferative ability, resulting in a greater than 100- fold increase in total cell number. NSCs and neural progenitors can be induced to differentiate by removing the mitogens and plating either intact neurospheres or dissociated cells on an adhesive substrate, in the presence of a low serum-containing medium. After several days, virtually all of the NSCs and progeny will differentiate into the three main neural cell types found in the CNS: neurons, astrocytes and oligodendrocytes. While the culture medium, growth factor requirements and culture protocols may vary, the neurosphere culture system has been successfully used to isolate NSCs and progenitors from different regions of the embryonic and adult CNS of many species including mouse, rat and human.

Adherent monolayer culture: Alternatively, cells obtained from CNS tissues can be cultured as adherent cultures in a defined, serum-free medium supplemented with EGF and/or bFGF, in the presence of a substrate such as poly-L-ornithine, laminin, or fibronectin. When plated under these conditions, the neural stem and progenitor cells will attach to the substrate-coated cultureware, as opposed to each other, forming an adherent monolayer of cells, instead of neurospheres. The reported success of expanding NSCs in long-term adherent monolayer cultures is variable and may be due to differences in the substrates, serum-free media andgrowth factors used.17 Recently, protocols that have incorporated laminin as the substrate, along with an appropriate serum-free culture medium containing both EGF and bFGF have been able to support long-term cultures of neural precursors from mouse and human CNS tissues.30-32 These adherent cells proliferate and become confluent over the course of 5 - 10 days. To passage the cultures, cells are detached from the surface by enzymatic treatment and replated under the same conditions as the primary culture. It has been reported that NSCs cultured under adherent monolayer conditions undergo symmetric divisions in long-term culture.30,33 Similar to the neurosphere culture system, adherently cultured cells can be passaged multiple times and induced to differentiate into neurons, astrocytes and oligodendrocytes upon mitogen removal and exposure to a low serum-containing medium.

Several studies have suggested that culturing CNS cells in neurosphere cultures does not efficiently maintain NSCs and produces a heterogeneous cell population, whereas culturing cells under serum-free adherent culture conditions does maintain NSCs.17 While these reports did not directly compare neurosphere and adherent monolayer culture methods using the same medium, growth factors or extracellular matrix to evaluate NSC numbers, proliferation and differentiation potential, they emphasize that culture systems can influence the in vitro functional properties of NSCs and neural progenitors. It is important that in vitro methodologies for NSC research are designed with this caveat in mind, and with a clear understanding of what the methodologies are purported to measure.34-35

Immunomagnetic or immunofluorescent cell isolation strategies using antibodies directed against cell surface markers present on stem cells, progenitors and mature CNS cells have been applied to the study of NSCs. Similar to stem cells in other systems, the phenotype of CNS stem cells has not been completely determined. Expression, or lack of expression, of CD34, CD133 and CD45 antigens has been used as a strategy for the preliminary characterization of potential CNS stem cell subsets. A distinct subset of human fetal CNS cells with the phenotype CD133+ 5E12+ CD34- CD45- CD24-/lo has the ability to form neurospheres in culture, initiate secondary neurosphere formation, and differentiate into neurons and astrocytes.36 Using a similar approach, fluorescence-activated cell sorting (FACS)- based isolation of nestin+ PNA- CD24- cells from the adult mouse periventricular region enabled significant enrichment of NSCs(80% frequency in sorted population, representing a 100-fold increase from the unsorted population).37 However, the purity of the enriched NSC population was found to be lower when this strategy was reevaluated using the more rigorous Neural Colony-Forming Cell (NCFC) assay.38-39 NSC subsets detected at different stages of CNS development have been shown to express markers such as nestin, GFAP, CD15, Sox2, Musashi, CD133, EGFR, Pax6, FABP7 (BLBP) and GLAST40-45. However, none of these markers are uniquely expressed by NSCs; many are also expressed by neural progenitor cells and other nonneural cell types. Studies have demonstrated that stem cells in a variety of tissues, including bone marrow, skeletal muscle and fetal liver can be identified by their ability to efflux fluorescent dyes such as Hoechst 33342. Such a population, called the side population, or SP (based on its profile on a flow cytometer), has also been identified in both mouse primary CNS cells and cultured neurospheres.46 Other non-immunological methods have been used to identify populations of cells from normal and tumorigenic CNS tissues, based on some of the in vitro properties of stem cells, including FABP7 expression and high aldehyde dehydrogenase (ALDH) enzyme activity. ALDH-bright cells from embryonic rat and mouse CNS have been isolated and shown to have the ability to generate neurospheres, neurons, astrocytes and oligodendrocytes in vitro, as well as neurons in vivo, when transplanted into the adult mouse cerebral cortex.47-50 NeuroFluor CDr3 is a membrane-permeable fluorescent probe that binds to FABP7 and can be used to detect and isolate viable neural progenitor cells from multiple species.42-43

Multipotent neural stem-like cells, known as brain tumor stem cells (BTSCs) or cancer stem cells (CSCs), have been identified and isolated from different grades (low and high) and types of brain cancers, including gliomas and medulloblastomas.51-52 Similar to NSCs, these BTSCs exhibit self-renewal, high proliferative capacity and multi-lineage differentiation potential in vitro. They also initiate tumors that phenocopy the parent tumor in immunocompromised mice.53 No unique marker of BTSCs has been identified but recent work suggests that tumors contain a heterogenous population of cells with a subset of cells expressing the putative NSC marker CD133.53 CD133+ cells purified from primary tumor samples formed primary tumors, when injected into primary immunocompromised mice, and secondary tumors upon serial transplantation into secondary recipient mice.53 However, CD133 is also expressed by differentiated cells in different tissues and CD133- BTSCs can also initiate tumors in immunocompromised mice.54-55 Therefore, it remains to bedetermined if CD133 alone, or in combination with other markers, can be used to discriminate between tumor initiating cells and non-tumor initiating cells in different grades and types of brain tumors. Recently, FABP7 has gained traction as a CNS-specific marker of NSCs and BTSCs.42-43, 57

Both the neurosphere and adherent monolayer culture methods have been applied to the study of BTSCs. When culturing normal NSCs, the mitogen(s) EGF (and/or bFGF) are required to maintain NSC proliferation. However, there is some indication that these mitogens are not required when culturing BTSCs.57 Interestingly, the neurosphere assay may be a clinically relevant functional readout for the study of BTSCs, with emerging evidence suggesting that renewable neurosphere formation is a significant predictor of increased risk of patient death and rapid tumor progression in cultured human glioma samples.58-60 Furthermore, the adherent monolayer culture has been shown to enable pure populations of glioma-derived BTSCs to be expanded in vitro.61

Research in the field of NSC biology has made a significant leap forward over the past ~30 years. Contrary to the beliefs of the past century, the adult mammalian brain retains a small number of true NSCs located in specific CNS regions. The identification of CNS-resident NSCs and the discovery that adult somatic cells from mouse and human can be reprogrammed to a pluripotent state,62-68 and then directed to differentiate into neural cell types, has opened the door to new therapeutic avenues aimed at replacing lost or damaged CNS cells. This may include transplantation of neural progenitors derived from fetal or adult CNS tissue, or pluripotent stem cells. Recent research has shown that adult somatic cells can be directly reprogrammed to specific cell fates, such as neurons, using appropriate transcriptional factors, bypassing the need for an induced pluripotent stem cell intermediate.69 Astroglia from the early postnatal cerebracortex can be reprogrammed in vitro to neurons capable of action potential firing, by the forced expression of a single transcription factor, such as Pax6 or the pro-neural transcription factor neurogenin-2 (Neurog2).70 To develop cell therapies to treat CNS injuries and diseases, a greater understanding of the cellular and molecular properties of neural stem and progenitor cells is required. To facilitate this important research, STEMCELL Technologies has developed NeuroCult proliferation and differentiation kits for human, mouse and rat, including xenofree NeuroCult-XF. The NeuroCult NCFC Assay provides a simple and more accurate assay to enumerate NSCs compared to the neurosphere assay. These tools for NSC research are complemented by the NeuroCult SM Neuronal Culture Kits, specialized serum-free medium formulations for culturing primary neurons. Together, these reagents help to advance neuroscience research and assist in its transition from the experimental to the therapeutic phase.

Spinal Cord Stem Cells Comments Off on Neural Stem Cells – Stemcell Technologies | October 2nd, 2019

Swiss pharmaceutical giant Novartis made history as the first company to win FDA approval for a CAR-T therapy in the United States. Novartis announced that its genetically modified autologous (self-derived) immunocellular therapy, Kymriah, will cost $475,000 per treatment course. Shortly thereafter, Kite Pharma announced the approval of its CAR-T therapy, Yescarta, in the U.S. with a list price of $373,000. While these prices are expensive, they are far from trendsetting.

In this article:

Pricing of cell therapies is controversialbecause most cell therapy products are priced exponentially higher than traditional drugs. Unfortunately, most drugs can be manufactured and stockpiled in large quantities for off-the-shelf use, while cell therapies involve living cells that require a different approach to commercial-scale manufacturing, transit, stockpiling, and patient use.

To date, the highest priced treatment has not been a cell therapy, but a gene therapy (Glybera). At the time of its launch, Glybera was the first gene therapy approved in the Western world, launching for sale in Germany at a cost close to $1 million per treatment.[1] The record-breaking price tag got revealed in November 2014, when Uniqure and its marketing partner Chiesi, filed a pricing dossier with German authorities to launch Glybera. Unfortunately, Glybera was later withdrawn from the European market due to lack of sales.

Following the approval of Glybera, Kymriah, Yescarta, and more than a dozen other cell therapies, conversations surrounding pricing and reimbursement have become a focal point within the cell therapy industry.

In contrast to pharmaceutical drugs, cell therapies require a different pricing analysis. Below, price tags are shown for approved cell therapy products that have reached the market (prices in US$) and for which there is standardized market pricing.

Pricing of Approved Cell Therapy Products:

Apligrafby Organogenesis & Novartis AG in USA = $1,500-2,500 per use [2]Carticelby Genzyme in USA = $15,000 to $35,000 [3]Cartistemby MEDIPOST in S. Korea = $19,000-21,000 [4],[5]Cupistemby Anterogen in South Korea = $3,000-5,000 per treatment [6]ChondroCelectby Tigenix in EU = ~ $24,000 (20,000) [7]Dermagraftby Advanced Tissue Science in USA = $1,700 per application [8],[9]Epicelby Vericel in theUnited States = $6,000-10,000 per 1% of total body surface area [10]Hearticellgramby FCB-Pharmicell in South Korea = $19,000 [11]HeartSheetby Terumo in Japan = $56,000 (6,360,000) for HeartSheet A Kit; $15,000 (1,680,000) for HeartSheet B Kit (*Each administration uses one A Kit and 5 B Kits)[12]Holoclarby Chiesi Framaceutici in EU = Unknown (very small patient population)Kymriahby Novartis in USA = $425,000 per treatment[13]Osteocelby NuVasive in USA = $600 per cc [14],[15]Prochymalby Osiris Therapeutics and Mesoblast in Canada = ~ $200,000 [16]Provengeby Dendreon and Valeant Pharma in USA = $93,000 [17], [18]SpheroxbyCO.DON AG in EU = $9,500 $12,000 (8,000 10,000) per treatment[19]Strimvelisby GSK in EU = $665,000 (One of worlds most expensive therapies) [20],[21]Temcellby JCR Pharmaceuticals Co. Ltd. in Japan = $115,000-170,000 [22]*Pricing of TEMCELL is $7,600 (868,680 per bag), with one bag of 72m cells administered twice weekly and 2m cells/kg of body weight required per administration[23]Yescartaby Kite Pharma in USA =$373,000[24]

As shown in the list above, wound care products tend to have the lowest cell therapy pricing, typically costing $1,500 to $2,500 per use. For example, Apligrafis created from cells found in healthy human skin and is used to heal ulcers that do not heal after 3-4 weeks ($1,500-2,500 per use), and Dermagraftis a skin substitute that is placed on your ulcer to cover it and to help it heal ($1,700 per application).

Interestingly, Epicel is a treatment for deep dermal or full thickness burns comprising a total body surface area of greater than or equal to 30%. It has higher pricing of $6,000-10,000 per 1% of total body surface area, because it is not used to treat a single wound site, but rather used to treat a large surface area of the patients body.

Next, cartilage-based cell therapy products tend to have mid-range pricing of $10,000 to $35,000. For example, Carticelis a product that consists of autologous cartilage cells (pricing of $15,000 to $35,000), CARTISTEM is a regenerative treatment for knee cartilage (pricing of $19,000 to $21,000), and ChondroCelectis a suspension for implantation that contains cartilage cells (pricing of $24,000).In July 2017,the EMA in Europe also approved Spheroxas a product for articular cartilage defects of the knee with a pricing of$9,500 $12,000 (8,000 10,000) per treatment.

The next most expensive cell therapy products are the ones that are administered intravenously, which range in price from approximately $90,000 to $200,000. For example, Prochymal is an intravenously administered allogenic MSC therapy derived from the bone marrow of adult donors (pricing of $200,000), Provenge is an intravenously administered cancer immunotherapy for prostate cancer ($93,000), and Temcell is an intravenously administered autologous MSC product for the treatment of acute GVHD after an allogeneic bone marrow transplant (pricing of $115,000-170,000).

Finally, many of the worlds most expensive cell therapies are gene therapies, ranging in price from $500,000 to $1,000,000. For example, Kymriah is the first CAR-T cell therapy to be FDA approved in the United States (pricing of $475,00 per treatment course).Strimvelis isan ex-vivo stem cell gene therapy to treat patients with a very rare disease called ADA-SCID (pricing of $665,000).

Although these generalizations do not hold true for every cell therapy product, they explain the majority of cell therapy pricing and provide a valuable model for estimating cell therapy pricing and reimbursement. This information is summarized in the following table.

TABLE. Pricing Scale for Approved Cell Therapies

Another point of reference is also valuable. The RIKEN Institute launched the worlds first clinical trial involving an iPSC-derived product when it transplanted autologous iPSC-derived RPE cells into a human patient in 2014.While the trial was later suspended due to safety concerns, it resumed in 2016, this time using an allogeneic iPSC-derived cell product.

The research team indicated that by using stockpiled iPS cells, the time needed to prepare for a graft can be reduced from 11 months to as little as one month, and the cost, currently around 100 million ($889,100), can be cut to one-fifth or less.[25]

While many factors contribute to cell therapy pricing, key variables that can be used to predict market pricing include:

Another compounding factor is market size, because wound healing and cartilage replacement therapies have significant patient populations, while several of the more expensive therapies address smaller patient populations.[26]

IPS Cell Therapy Comments Off on Pricing Of Approved Cell Therapy Products – BioInformant | October 2nd, 2019

The challenges of gene and cell therapists can be divided into three broad categories based on disease, development of therapy, and funding.

Challenges based on the disease characteristics: Disease symptoms of most genetic diseases, such as Fabrys, hemophilia, cystic fibrosis, muscular dystrophy, Huntingtons, and lysosomal storage diseases are caused by distinct mutations in single genes. Other diseases with a hereditary predisposition, such as Parkinsons disease, Alzheimers disease, cancer, and dystonia may be caused by variations/mutations in several different genes combined with environmental causes. Note that there are many susceptible genes and additional mutations yet to be discovered. Gene replacement therapy for single gene defects is the most conceptually straightforward. However, even then the gene therapy agent may not equally reduce symptoms in patients with the same disease caused by different mutations, and even the samemutationcan be associated with different degrees of disease severity. Gene therapists often screen their patients to determine the type of mutation causing the disease before enrollment into a clinical trial.

The mutated gene may cause symptoms in more than one cell type. Cystic fibrosis, for example, affects lung cells and the digestive tract, so the gene therapy agent may need to replace the defective gene or compensate for its consequences in more than one tissue for maximum benefit. Alternatively, cell therapy can utilizestem cellswith the potential to mature into the multiple cell types to replace defective cells in different tissues.

In diseases like muscular dystrophy, for example, the high number of cells in muscles throughout the body that need to be corrected in order to substantially improve the symptoms makes delivery of genes and cells a challenging problem.

Some diseases, like cancer, are caused by mutations in multiple genes. Although different types of cancers have some common mutations, every tumor from a single type of cancer does not contain the same mutations. This phenomenon complicates the choice of a single gene therapy tactic and has led to the use of combination therapies and cell elimination strategies. For more information on gene and cell therapy strategies to treat cancer, please refer to the Cancer and Immunotherapy summary in the Disease Treatment section.

Disease models in animals do not completely mimic the human diseases and viralvectorsmay infect various species differently. The testing of vectors in animal models often resemble the responses obtained in humans, but the larger size of humans in comparison to rodents presents additional challenges in the efficiency of delivery and penetration of tissue.Gene therapy, cell therapy, and oligonucleotide-based therapy agents are often tested in larger animal models, including rabbit, dog, pig and nonhuman primate models. Testing human cell therapy in animal models is complicated by immune rejections. Furthermore, humans are a very heterogeneous population. Their immune responses to the vectors, altered cells, or cell therapy products may differ or be similar to results obtained in animal models.

Challenges in the development of gene and cell therapy agents: Scientific challenges include the development of gene therapy agents that express the gene in the relevant tissue at the appropriate level for the desired duration of time. There are a lot of issues in that once sentence, and while these issues are easy to state, each one requires extensive research to identify the best means of delivery, how to control sufficient levels or numbers of cells, and factors that influence duration of gene expression or cell survival. After the delivery modalities are determined, identification and engineering of a promoter and control elements (on/off switch and dimmer switch) that will produce the appropriate amount of protein in the target cell can be combined with the relevant gene. This gene cassette is engineered into a vector or introduced into thegenomeof a cell and the properties of the delivery vehicle are tested in different types of cells in tissue culture. Sometimes things go as planned and then studies can be moved onto examination in animal models. In most cases, the gene/cell therapy agent may need to be improved further by adding new control elements to obtain the desired responses in cells and animal models.

Furthermore, the response of the immune system needs to be considered based on the type of gene or cell therapy being undertaken. For example, in gene or cell therapy for cancer, one aim is to selectively boost the existing immune response to cancer cells. In contrast, to treat genetic diseases like hemophilia and cystic fibrosis the goal is for the therapeutic protein to be accepted as an addition to the patients immune system.

If the new gene is inserted into the patients cellularDNA, the intrinsic sequences surrounding the new gene can affect its expression and vice versa. Scientists are now examining short DNA segments that may insulate the new gene from surrounding control elements. Theoretically, these insulator sequences would also reduce the effect of vector control signals in the gene cassette on adjacent cellular genes. Studies are also focusing on means to target insertion of the new gene into safe areas of the genome, to avoid influence on surrounding genes and to reduce the risk of insertional mutagenesis.

Challenges of cell therapy include the harvesting of the appropriate cell populations and expansion or isolation of sufficient cells for one or multiple patients. Cell harvesting may require specific media to maintain the stem cells ability toself-renew and mature into the appropriate cells. Ideally extra cells are taken from the individual receiving therapy. Those additional cells can expand in culture and can be induced to becomepluripotent stem cells(iPS), thus allowing them to assume a wide variety of cell types and avoiding immune rejection by the patient. The long term benefit of stem cell administration requires that the cells be introduced into the correct target tissue and become established functioning cells within the tissue. Several approaches are being investigated to increase the number of stem cells that become established in the relevant tissue.

Another challenge is developing methods that allow manipulation of the stem cells outside the body while maintaining the ability of those cells to produce more cells that mature into the desired specialized cell type. They need to provide the correct number of specialized cells and maintain their normal control of growth and cell division, otherwise there is the risk that these new cells may grow into tumors.

Challenges in funding: In most fields, funding for basic or applied research for gene and cell therapy is available through the National Institutes of Health (NIH) and private foundations. These are usually sufficient to cover the preclinical studies that suggest a potential benefit from a particular gene and cell therapy. Moving into clinical trials remains a huge challenge as it requires additional funding for manufacturing of clinical grade reagents, formal toxicology studies in animals, preparation of extensive regulatory documents, and costs of clinical trials.Biotechnology companies and the NIH are trying to meet the demand for this large expenditure, but many promising therapies are slowed down by lack of funding for this critical next phase.

Globally, the stem cell therapy market is expected to be worth $40 billion by 2020 and $180 billion by 2030. The largest number of marketed cell therapy products is used for the treatment of notably non-healing wounds/skin (46%) and muscular-skeletal injuries (35%). This trend will change as more and stem cell therapy products for cancer and heart disease complete their clinical trials and are approved for market release.

Adult stem cell leads the market due to low contamination during sub-culture and expansion, relatively low labour production and compatibility with the human body.Just the Induced pluripotent stem cells (IPScs) are expected to report revenue of over USD 4.5 billion by 2020, on account of the analogous nature of its origin.With the continued growth of medical tourism hubs like India, Singapore, and Thailand, Asia is expected to maintain its place as the epicentre of stem cell research and therapy. These opportunities include contract research outsourcing and rising patient population with neurological and other chronic conditions in the region. Japan, Singapore and South Korea are the frontrunners and are set to dominate the APAC stem cell market in the coming years.

IPS Cell Therapy Comments Off on Cell Therapy World Asia – IMAPAC – Imagine your Impact | October 2nd, 2019

We are thrilled to share an excerpt form Dr. Q Schulte aufm Erley's article on Plant Stem Cells. Dr. Q is an entrepreneur, scientist and founder of one of our most loved partners: Shtrands. Shtrands is a beauty industry innovator. They provide a hair care concierge service that brings you curated products and expert advice to match your hair texture, scalp condition and styling needs.

The highly competitive cosmetics industry is always looking for the next best ingredient(s) that can fight the aging process and this led to a sizable increase in the number of anti-aging products on the market. With this is coming an increased number of active ingredients developed for this category; one of these ingredients is stem cell extract.This is an ingredient that must be assessed carefully, as marketing claims often push the limits of the available science.

The concept of stem cells originated at the end of the 19th century as a theoretical postulate to account for the ability of certain tissues (blood, skin, etc.) to renew themselves for the lifetime of organisms even though they are comprised of short-lived cells. Stem cells isolation and identification happened many years later though.

Stem cells have received a fair share of attention in the public debate mostly in connection with their potential for biomedical application and therapies. While the promise of organ regeneration have captured our imagination, it has gone almost unnoticed that plant stem cells represent the ultimate origin of much of the food we eat, the oxygen we breathe, as well the fuels we burn. Thus, plant stem cells may be ranked among the most important cells for human well-being.

A stem cell is a generic cell that can make exact copies of itself (daughters) indefinitely. These daughters can remain stem cells or further undergo differentiation (2). Such that a stem cell has the ability to make specialized cells for various tissues in the body, such as heart muscle, skin tissue, and liver tissue.

Because of their self-renewal functions, stem cells are the most important cells in the skin, as they are the source for continuous regeneration of the epidermis. Stem cell cosmetics are developed based on stem cell technology, which involves using extracts or culture media of stem cells. However, cosmetics containing human stem cells or their extracts have not been released into the market due to legal, ethical, and safety concerns. Meanwhile, plant stem cells, which circumvent these problems, are highly regarded in the cosmetics industry for improving culture technology.

The EUprohibits the use of cells, tissues, or products of human origin in cosmetics; stem cell therapy for anti-aging has not been approved or been deemed safe or effective in USA by the FDA. Furthermore, its use outside of a clinical research trial (which would be listed at http://www.clinicaltrials.gov) is prohibited. Whereas the Korea Food and Drug Association has allowed the use of sources originating from stem cell media in cosmetics since 2009 (3).

So, any cosmetics marketed as containing stem cells found on US market (should) contain stem cells extracted from plants.

A major difference between animal and plant stem cells is that plant stem cells provide cells for complete organs (branches, leaves, etc.), compared with the animal stem cells, which regenerate cells restricted to one tissue type.

Plants have nowhere to run when times get tough, so they must rely on an inner body plan to generate developmental responses to environmental changes.

Research by many labs in the last decades has uncovered a set of independent stem cell systems that fulfill the specialized needs of plant development and growth in four dimensions. In some long-lived plants, such as trees, plant stem cells remain active over hundreds or even thousands of years, revealing the exquisite precision in the underlying control of proliferation, self-renewal and differentiation.

There is some confusion around the term stem cell due to the marketing verbiage used by the cosmetic companies. In topical cosmetics the formulations dont contain stem cells straight out of the plants. They are actually a range ofplant stem cell extracts, which are manufactured using a cell culture technology.This technology consists of many and complicated methods that should ensure growth of plant cells, tissues or organs in the environment with a microbe-free nutrient. The plant cell technologyallows synthesis of the biologically active substances that exist in plants, but are not commonly available in natural environment or are difficult to obtain by chemical synthesis.

The extracts obtained through this technology from the plant stem cells are currently used for production of both common or professional care cosmetics (4).

The beneficial apple properties are known for centuries. Apples are cultivated today only for their taste, but earlier the main criterion of the type selection was the shelf life of the fruits.

One of such apple-tree types isUttwiler Spatlauberwhich is growing in Switzerland. This is a type cultivated solely due to a possible long-time storage of fruits, which remain fresh even for several months.Some trees come from the plant cutting sets planted during the 18th century!!!

The stem cell extracts are made in 2 main steps: first, the tissue material is obtained from apples (collected from a cut surfaces of the apples). Secondly, the material is going through a complicated biotechnological process to make the stem cell extracts that contains certain active ingredients. These are actually the ingredients used in formulations marketed as containing stem cells (5).

Swiss biotech company Mibelle Biochemistry created the product named PhytoCellTecTMMalus Domestica, that is a liposomal formulation (extract) derived from the stem cells of the Uttwiler Spatlauber apples. The company has published in vitro experiments done with hair follicles that showed the ability of theUttwiler Spatlauberstem cell extract to delaying of the tissue atrophy process (6); this ingredient delays hair aging.

At Teadora, we chose to includeMibelle'sPhytoCellTecTM Argan Plant Stem Cells in our ButterandBrazilian Glow Oiland here are the details from Mibelle that helped to convince us this ingredient was a must have companion to the huge list of active superfruits we crafted into our products, read on, it's pretty cool:

Deep-Seated Rejuvenation of the Skin:In order to maintain the skin in a healthy condition,cutaneous tissue is being continuously regenerated.This regenerative capacity relies on adult stem cells inthe skin. While considerable research has been done onepidermal stem cells, dermal stem cells were identifiedonly in 2009. The dermis is the middle layer of the skinand gives it tensile strength and elasticity, therefore it isalso the site where wrinkles originate.

PhytoCellTec Argan was developed to improvethe regenerative capacity of dermal stem cells therebyachieving deep-seated rejuvenation of the skin.

PhytoCellTec Argan is a powder based on stem cellsof the argan tree, one of the oldest tree species in theworld.In order to evaluate which active ingredient effectivelypromotes dermal stem cell activity, a stable humandermal papilla cell line was used as a new test system:stem cell activity is assessed based on the expression ofthe Sox2 gene, which is an established stem cell marker.Furthermore, the characteristic property of stem cells togrow in three-dimensional spherical colonies serves asa second observable indicator of stem cell viability inthis assay.

Clinical studies performed on healthy volunteers showedthat PhytoCellTec Argan:

effectively stimulates the regeneration of dermalconnective tissue, thereby increasing skin density

helps the skin to regain its firmness

significantly reduces wrinkle depth in crows feet area.

PhytoCellTec Argan is the very first active ingredientthat is capable of both protecting and vitalizing humandermal stem cells. This will not only help to acceleratethe skins natural repair process but also fights skin agingright at the root. Here are some of the amazing benefits:

Vitalizes and protects dermal stem cells Reduces wrinkles Tightens and tones skin tissues Increases skin firmness and density Deep-seated rejuvenation of the skinFirst cosmetic active with proven results forprotecting and vitalizing dermal stem cells

A stem cell treatment which is in primary stages of trials, has proved effective in treatment when using non-donor stem cells.

Spinal cord injuries can happen to anyone, the condition tends to be a result of a fall or accident, although it can also be an outcome of a brain injury. When the spinal cord is injured the pathway is practically closed. Nerve impulses cant get through, this has problematic symptoms such as; a person suffering paralysis, a loss of mobility and sensation.

Using stem cell therapy where the stem cells havent been donated mean they are more likely to be accepted by the patient when they are injected.

This new trial was published on the 9th of May 2018 inScience Translational Medicine, a team of international scientist led by the University of California San Diego School of Medicine successfully grafted stem cells back into a spinal cord without aggravating the immune system or reducing it in any way.

The stem cells injected in the trial were accepted and survived long term without causing a tumor. Researchers also found that the same cells showed a long-term survival when injected into an injured spinal cord.

Senior author Martin Marsala, MD, professor in the Department of Anesthesiology at UC San Diego School of Medicine and a member of the Sanford Consortium for Regenerative Medicine, said: The promise of iPSCs is huge, but so too have been the challenges. In this study, weve demonstrated an alternate approach,

We took skin cells, then induced them to becomeneural precursor cells(NPCs), destined to become nerve cells. Because they are syngeneicgenetically identical with the cell-graftthey are immunologically compatible. They grow and differentiate with no immunosuppression required.

Co-author Samuel Pfaff, PhD, professor and Howard Hughes Medical Institute Investigator at Salk Institute for Biological Studies, said: Using RNA sequencing and innovative bioinformatic method to deconvolute the RNAs species-of-origin, the research team demonstrated that iPSC-derived neural precursors safely acquire the genetic characteristics of mature CNS tissue.

In their study, researchers found that the stem cells survived and differentiated into neurons and supporting glial cells. The grafted stem cells were detected to be working and responsive seven months after transplantation.

Researchers, then grafted stem cells into similar tissues in the body that had severespinal cord injuries, this injection of stem cells was then followed by a transient four-week course of drugs that suppress the immune system. The stem cells then could work in the spinal cord and begin to allow movement.

Our current experiments are focusing on generation and testing of clinical grade human iPSCs, which is the ultimate source of cells to be used in future clinical trials for treatment of spinal cord and central nervous system injuries in a syngeneic or allogeneic setting, said Marsala.

Because long-term post-grafting periodsone to two yearsare required to achieve a full graftedcells-induced treatment effect, the elimination of immunosuppressive treatment will substantially increase our chances in achieving more robust functional improvement in spinal trauma patients receiving iPSC-derived NPCs.

In our current clinical cell-replacement trials, immunosuppression is required to achieve the survival of allogeneic cell grafts. The elimination of immunosuppression requirement by using syngeneic cell grafts would represent a major step forward said co-author Joseph Ciacci, MD, a neurosurgeon at UC San Diego Health and professor of surgery at UC San Diego School of Medicine.

The treatment is expected to go to the next stage of trials in the next few years, with the hope that this stem cell therapy can be used in modern medicine.

This research forms another significant step towards stem cell therapy and spinal cord injury. Yet the type of cell used is still in contention when it comes to human application. iPSC are undoubtedlyauseful research tool in the laboratory and as a result because of their pluripotency, many scientists continue to hopethat they can one day be used for therapeutic applications, including regenerative medicine in humans. This strategy continues to proveproblematic ashave been shown to produce lesions and tumors when injected or transplanted.

This type of research does however contribute to ongoing developments for the use of stem cells, where possible use of Adult Stem Cells, known not to be problematic as a result of tumors could be used.

We believe the best stem cells to use in emergingtreatmentswill be the patients own stem cells as this doesnt require a search for a suitable donor and in turn, eliminates chances of the transplanted cells being rejected.

Stem cells have the potential to differentiate into cardiovascular cell lineages and to stimulate tissue regeneration in a paracrine/autocrine manner; thus, they have been extensively studied as candidate cell sources for cardiovascular regeneration. Several preclinical and clinical studies addressing the therapeutic potential of endothelial progenitor cells (EPCs) and cardiac progenitor cells (CPCs) in cardiovascular diseases have been performed. For instance, autologous EPC transplantation and EPC mobilization through pharmacological agents contributed to vascular repair and neovascularization in different animal models of limb ischemia and myocardial infarction. Also, CPC administration and in situ stimulation of resident CPCs have been shown to improve myocardial survival and function in experimental models of ischemic heart disease. However, clinical studies using EPC- and CPC-based therapeutic approaches have produced mixed results. In this regard, intracoronary, intra-myocardial or intramuscular injection of either bone marrow-derived or peripheral blood progenitor cells has improved pathological features of tissue ischemia in humans, despite modest or no clinical benefit has been observed in most cases. Also, the intriguing scientific background surrounding the potential clinical applications of EPC capture stenting is still waiting for a confirmatory proof. Moreover, clinical findings on the efficacy of CPC-based cell therapy in heart diseases are still very preliminary and based on small-size studies.

Despite promising evidence, widespread clinical application of both EPCs and CPCs remains delayed due to several unresolved issues. The present review provides a summary of the different applications of EPCs and CPCs for cardiovascular cell therapy and underlies their advantages and limitations.

Nicholas Geissse, PhD, CSO, NanoSurface Biomedical

Alec S.T. Smith, PhD, Acting Instructor, Bioengineering, University of Washington

hiPSC-CM maturation is sensitive to structural cues from the extracellular matrix (ECM). Failure to reproduce these signals in vitro can hamper experimental reproducibility and fidelity. Engineering approaches that address this gap typically trade off complexity with throughput, making them difficult to deploy in the modern drug development paradigm. The NanoSurface Car(ina) platform leverages ECM engineering approaches that are fully compatible with industry-standard instrumentation including HCI- and MEA-based assays, thereby improving their predictive power.

Arne Bruyneel, PhD, Postdoctoral Fellow, Mark Mercola Lab, Cardiovascular Institute, Stanford University School of Medicine

Cardiac arrhythmia and myopathy is a major problem with cancer therapeutics, including newer small molecule kinase inhibitors, and frequently causes heart failure, morbidity and death. However, currentin vitromodels are unable to predict cardiotoxicity, or are not scalable to aid drug development. However, with recent progress in human stem cell biology, cardiac differentiation protocols, and high throughput screening, new tools are available to overcome this barrier to progress.

Yishan Sun, PhD, Investigator, Novartis Institutes for BioMedical Research (NIBR)

Human iPSC-derived neurons provide the foundation for phenotypic assays assessing genetic or pharmacological effects in a human neurobiological context. The onus is on assay developers to generate application-relevant neuronal cell types from iPSCs, which is not always straightforward, given the diversity of neuronal classes in the human brain and their developmental trajectories. Here we present two case studies to illustrate the use of iPSC-derived telencephalic GABAergic interneurons in neuropsychiatric research.

8:15 Levering iPSC to Understand Mechanism of Toxicity

Jeff Willy, PhD, Research Fellow, Discovery and Investigative Toxicology, Vertex

The discovery of mammalian cardiac progenitor cells suggests that the heart consists of not only terminally differentiated beating cardiomyocytes, but also a population of self-renewing stem cells. We recently showed that iPSC cardiomyocytes can be utilized not only to de-risk compounds with potential for adverse cardiac events, but also to understand underlying mechanisms of cell-specific toxicities following xenobiotic stress, thus preventing differentiation and self-renewal of damaged cells.

2:25 The Evolving Roles of Evolving Human Stem Cell-Derived Cardiomyocyte Preparations in Cardiac Safety Evaluations

Gary Gintant, PhD, Senior Research Fellow, AbbVie

Human induced pluripotent stem cell-derived cardiomyocytes (hiPSC-CMs) hold great promise for preclinical cardiac safety testing. Recent applications focus on drug effects on cardiac electrophysiology, contractility, and structural toxicities, with further complexity provided by the growing number of hiPSC-CM preparations being developed that may also promote myocyte maturity. The evolving roles (both non-regulatory and regulatory) of these preparations will be reviewed, along with general considerations for their use in cardiac safety evaluations.

2:55 Pharmacogenomic Prediction of Drug-Induced Cardiotoxicity Using hiPSC-Derived Cardiomyocytes

Paul W. Burridge, PhD, Assistant Professor, Department of Pharmacology, Center for Pharmacogenomics, Northwestern University Feinberg School of Medicine

We have demonstrated that human induced pluripotent stem cell-derived cardiomyocytes successfully recapitulate a patients predisposition to chemotherapy-induced cardiotoxicity, confirming that there is a genomic basis for this phenomenon. Here we will discuss our recent work deciphering the pharmacogenomics behind this relationship, allowing the genomic prediction of which patients are likely to experience this side effect. Our efforts to discover new drugs to prevent doxorubicin-induced cardiotoxicity will also be reviewed.

3:25 Exploring the Utility of iPSC-Derived 3D Cortical Spheroids in the Detection of CNS Toxicity

Qin Wang, PhD, Scientist, Drug Safety Research and Evaluation, Takeda

Drug-induced Central Nervous System (CNS) toxicity is a common safety attrition for project failure during discovery and development phases due low concordance rates between animal models and human, absence of clear biomarkers, and a lack of predictive assays. To address the challenge, we validated a high throughput human iPSC-derived 3D microBrain model with a diverse set of pharmaceuticals. We measured drug-induced changes in neuronal viability and Ca channel function. MicroBrain exposure and analyses were rooted in therapeutic exposure to predict clinical drug-induced seizures and/or neurodegeneration. We found that this high throughput model has very low false positive rate in the prediction of drug-induced neurotoxicity.

3:55 Linking Liver-on-a-Chip and Blood-Brain-Barrier-on-a-Chip for Toxicity Assessment

Sophie Lelievre, DVM, PhD, LLM, Professor, Cancer Pharmacology, Purdue University College of Veterinary Medicine

One of the challenges to reproduce the function of tissues in vitro is the maintenance of differentiation. Essential aspects necessary for such endeavor involve good mechanical and chemical mimicry of the microenvironment. I will present examples of the management of the cellular microenvironment for liver and blood-brain-barrier tissue chips and discuss how on-a-chip devices may be linked for the integrated study of the toxicity of drugs and other molecules.

Overview of current stem cell-based approaches to treat heart disease

Since heart failure after heart attacks results from death of heart muscle cells, researchers have been developing strategies to remuscularize the damaged heart wall in efforts to improve its function. Researchers are transplanting different types of stem cell and progenitor cells (see above) into patients to repair the damaged heart muscle. These strategies have mainly used either adult stem cells (found in bone marrow, fat, or the heart itself) or pluripotent (ES or iPS) cells.

Preliminary results from experiments with adult stem cells showed that they appeared to improve cardiac function even though they died shortly after transplantation. This led to the idea that these cells can release signals that can improve function without replacing the lost muscle. Clinical trials began in the early 2000s transplanting adult stem cells from the bone marrow and then from the heart. These trials demonstrated that transplanting cells into damaged hearts is feasible and generally safe for patients. However, larger trials that were randomized, blinded, and placebo-controlled, showed fewer indications of improved function. The consensus now is that adult stem cells have modest, if any, benefit to cardiac function.

Research shows that pluripotent stem cell-derived cardiomyocytes can form beating human heart muscle cells that both release the necessary signals and replace muscle lost to heart attack. Transplantation of pluripotent stem cell-derived cardiac cells have demonstrated substantial benefits to cardiac function in animal models of heart disease, from mice to monkeys. Recently, pluripotent stem cell-derived interventions were used in clinical trials for the first time. Patches of human heart muscle cells derived from the stem cells were transplanted onto the surface of failing hearts. Early results suggest that this approach is feasible and safe, but it is too early to know whether there are functional benefits.Research is ongoing to test cellular therapies to treat heart attacks by combining different types of stem cells, repeating transplantations, or improving stem cell patches. Clinical trials using these improved methods are currently targeted to begin around 2020.Unfortunately, many unscrupulous clinics are making unsubstantiated claims about the efficacy of stem cell therapies for heart failure, creating confusion about the current state of cellular approaches for heart failure.

Heart Disease A Closer Look at Stem Cells

Cardiac Stem Cells Comments Off on Heart Disease A Closer Look at Stem Cells | June 1st, 2019

Stem cells can do a lot of things - they can heal damaged tissue, reduce inflammation and restore function to damaged tissues. Did you know that stem cells can also improve your skin's quality and reduce the signs of aging? Innovations Stem Cell Center offers fat stem cell therapy for not only a wide array of medical conditions, but also for powerful anti-aging benefits.

How Can Stem Cell Therapy Improve Skin Quality?

Stem cells can help improve skin quality by helping to heal tissues that have been damaged by:

Aging. The aging process causes the breakdown of skin cells and skin quality, leaving the skin looking dull and dirty. Skin also loses elasticity and tightness.

Genetics. Genetics plays a large part in how your skin ages, and it's hard to fight it with over-the-counter products and treatments.

Poor diet. Lack of quality nutrition can negatively impact both the body and the skin. When the skin is not supported through a healthy diet, skin becomes dull, drab and damaged.

Environment. Environmental factors that affect the skin include pollution, dirt and germs. These things clog the pores, dull your appearance and lead to blemishes, acne and breakouts. Environmental factors also include prolonged exposure to the sun, which can cause pigmentation problems and destroy collagen and elastin.

How Is Stem Cell Therapy Used for the Skin?

One of the ways stem cell therapy is used for the skin is through a stem cell face-lift procedure. During this treatment, Dr. Johnson harvests stem cells from unwanted fat taken from another area of your body, such as your lower back or abdomen.

After the cells are harvested, they are separated from the blood and other tissue and then injected into your face with tiny needles.

The stem cell face-lift can be combined with other procedures, such as the facial fat transfer. Combining the procedures increases the odds of stem cell survival and boosts the anti-aging benefits.

What Are the Benefits of Stem Cell Therapy for the Skin?

Patients who undergo stem cell therapy for anti-aging benefits see changes in their skin such as:

NSI-566 grafted injured spines in rats with near complete cavity-filling

The differentiation profile of grafted cells showed all three neural lineage cells

High-density human axonal sprouting was seen throughout the NSI-566 grafted region

NSI-566 transplanted in the spinal injury site of patients can be performed safely

We tested the feasibility and safety of human-spinal-cord-derived neural stem cell (NSI-566) transplantation for the treatment of chronic spinal cord injury (SCI). In this clinical trial, four subjects with T2T12 SCI received treatment consisting of removal of spinal instrumentation, laminectomy, and durotomy, followed by six midline bilateral stereotactic injections of NSI-566 cells. All subjects tolerated the procedure well and there have been no serious adverse events to date (1827months post-grafting). In two subjects, one to two levels of neurological improvement were detected using ISNCSCI motor and sensory scores. Our results support the safety of NSI-566 transplantation into the SCI site and earlysigns of potential efficacy in three of the subjects warrant further exploration of NSI-566 cells in dose escalation studies. Despite these encouraging secondary data, we emphasize that this safety trial lacks statistical power or a control group needed to evaluate functional changes resulting from cell grafting.

Workflow Stages

Figure 1. hPSC Single-Cell Cloning Workflow with CloneR

On day 0, human pluripotent stem cells (hPSCs) are seeded as single cells at clonal density (e.g. 25 cells/cm2) or sorted at 1 cell per well in 96-well plates in TeSR (mTeSR1 or TeSR-E8) medium supplemented with CloneR. On day 2, the cells are fed with TeSR medium containing CloneR supplement. From day 4, cells are maintained in TeSR medium without CloneR. Colonies are ready to be picked between days 10 - 14. Clonal cell lines can be maintained long-term in TeSR medium.

Figure 2. CloneR Increases the Cloning Efficiency of hPSCs and is Compatible with Multiple hPSC Lines and Seeding Protocols

TeSR medium supplemented with CloneR increases hPSC cloning efficiency compared with cells plated in TeSR containing ROCK inhibitor. Cells were seeded (A) at clonal density (25 cells/cm2) in mTeSR1 and TeSR-E8 and (B) by single-cell deposition using FACS (seeded at 1 cell/well) in mTeSR1.

Figure 3. CloneR Increases the Cloning Efficiency of hPSCs at Low Seeding Densities

hPSCs plated in mTeSR1 supplemented with CloneR demonstrated significantly increased cloning efficiencies compared to cells plated in mTeSR1 containing ROCK inhibitor (10M Y-27632). Shown are representative images of alkaline phosphatase-stained colonies at day 7 in individual wells of a 12-well plate. H1 human embryonic stem (hES) cells were seeded at clonal density (100 cells/well, 25 cells/cm2) in mTeSR1 supplemented with (A) ROCK inhibitor or (B) CloneR on Vitronectin XF cell culture matrix.

Figure 4. CloneR Yields Larger Single-Cell Derived Colonies

hPSCs seeded in mTeSR1 supplemented with CloneR result in larger colonies than cells seeded in mTeSR1 containing ROCK inhibitor (10M Y-27632). Shown are representative images of hPSC clones established after 7 days of culture in mTeSR1 supplemented with (A) ROCK inhibitor or (B) CloneR.

Figure 5. Clonal Cell Lines Established Using CloneR Display Characteristic hPSC Morphology

Clonal cell lines established using mTeSR1 or TeSR-E8 medium supplemented with CloneR retain the prominent nucleoli and high nuclear-to-cytoplasmic ratio characteristic of hPSCs. Representative images at passage 7 after cloning are shown for clones derived from the parental (A) H1 hES cell and (B) WLS-1C human induced pluripotent stem (iPS) cell lines.

Figure 6. Clonal Cell Lines Established with CloneR Express High Levels of Undifferentiated Cell Markers

hPSC clonal cell lines established using mTeSR1 supplemented with CloneR express comparable levels of undifferentiated cell markers, OCT4 (Catalog #60093) and TRA-1-60 (Catalog #60064), as the parental cell lines. (A) Clonal cell lines established from parental H1 hES cell line. (B) Clonal cell lines established from parental WLS-1C hiPS cell line. Data is presented between passages 5 - 7 after cloning and is shown as mean SEM; n = 2.

Figure 7. Clonal Cell Lines Established Using CloneR Display a Normal Karyotype

Representative karyograms of clones derived from parental (A) H1 hES cell and (B) WLS-1C hiPS cell lines demonstrate that the clonal lines established with CloneR have a normal karyotype. Cells were karyotyped 5 passages after cloning, with an overall passage number of 45 and 39, respectively.

Figure 8. Clonal Cell Lines Established Using CloneR Display Normal Growth Rates

Fold expansion of clonal cell lines display similar growth rates to parental cell lines. Shown are clones (red) and parental cell lines (gray) for (A) H1 hES cell and (B) WLS-1C hiPS cell lines.

Bone has well documented natural healing capacity that normally is sufficient to repair fractures and other common injuries. However, the properties of bone change throughout life, and aging is accompanied by increased incidence of bone diseases and compromised fracture healing capacity, which necessitate effective therapies capable of enhancing bone regeneration. The therapeutic potential of adult mesenchymal stem cells (MSCs) for bone repair has been long proposed and examined. Actions of MSCs may include direct differentiation to become bone cells, attraction and recruitment of other cells, or creation of a regenerative environment via production of trophic growth factors. With systemic aging, MSCs also undergo functional decline, which has been well investigated in a number of recent studies. In this review, we first describe the changes in MSCs during aging and discuss how these alterations can affect bone regeneration. We next review current research findings on bone tissue engineering, which is considered a promising and viable therapeutic solution for structural and functional restoration of bone. In particular, the importance of MSCs and bioscaffolds is highlighted. Finally, potential approaches for the prevention of MSC aging and the rejuvenation of aged MSC are discussed.
