The patches may be effective at helping to restore the heart following a myocardial infarction, as the heart isnt able to restore lost cells on its own.

A team of researchers from University of Minnesota-Twin Cities, University of Wisconsin-Madison, and University of Alabama-Birmingham have developed a technique for 3D printing cardiac patches seeded with living cells. The patches may be effective at helping to restore the heart following a myocardial infarction, as the heart isnt able to restore lost cells on its own.

The technology has already been tested on a mouse model following an induced heart attack in which cardiac function wa significantly improved in four weeks following the application of the patch.

The patch is structurally based on how proteins naturally assemble within cardiac tissue. A highly detailed technique called multiphoton-excited 3D printing was used to create an extracellular matrix that was then seeded with about 50,000 cardiomyocytes, smooth muscle cells, and endothelial cells obtained from human-induced pluripotent stem cells.

The patch began beating on its own only a day after placing the cells and calcium transients, which are intercellular signaling mechanisms, were detected and increased over the following week.

Researchers have showncertain cardiac glycosides can reduce hepatocyte production of aprecursor of LDL cholesterol.

Familial hypercholesterolaemia (FH) is a rare genetic disease that affects the production of functioning low-density lipoprotein (LDL) receptors in the liver. When patients have mutations in both copies of the LDL receptor gene, they do not respond to statins and have limited pharmaceutical treatment options available because of a lack of accurate disease models.

Reporting in Cell Stem Cell on 6 April 2017[1], researchers used FH human hepatocytes derived from induced pluripotent stem cells to screen for existing drugs that might lower apolipoprotein B (apoB) a precursor of LDL cholesterol.

The team found that all nine cardiac glycosides in their drug library reduced levels of apoB in the hepatocytes. In an analysis of historical patient data, the researchers found a reduction in serum LDL-C comparable to that seen with statins in patients taking cardiac glycosides.

The researchers say the results demonstrate the potential of their stem-cell based approach for identifying new treatment candidates for inherited liver diseases.

Stem-cell screening finds statin alternative for hypercholesterolaemia - The Pharmaceutical Journal

SOUTH SAN FRANCISCO, CA--(Marketwired - April 27, 2017) - VistaGen Therapeutics Inc. (VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, announced today the peer-reviewed publication of nonclinical studies of the effects of AV-101 (4-Cl-KYN), its CNS prodrug candidate, in four well-established nonclinical models of pain.

The publication, titled: "Characterization of the effects of L-4-chlorokynurenine on nociception in rodents," by lead author, Tony L. Yaksh, Ph.D., and co-authors, Robert Schwarcz, Ph.D. and H. Ralph Snodgrass, Ph.D., was recently published in The Journal of Pain (DOI: 10.1016/j.jpain.2017.03.014) and is available online at http://www.jpain.org/article/S1526-5900(17)30552-7/abstract.

"In these studies, AV-101 was found to have robust anti-nociceptive effects, similar to gabapentin, but with a better side effect profile in several pre-clinical models of hyperalgesia and allodynia, results suggest AV-101's potential for treating multiple hyperpathic pain states," reported Tony L. Yaksh, Ph.D., Professor in Anesthesiology at the University of California, San Diego (UCSD).

"In comparison to gabapentin and other agents commonly used by millions of patients battling chronic neuropathic pain, we believe AV-101 has the potential to reduce debilitating pain effectively without causing burdensome side effects. Many neuropathic pain treatments on the market today have side effects, including anxiety, depression, mild cognitive impairment and sedation. The positive results published in these studies fall in line with our goal of advancing Phase 2 clinical development of AV-101 across a broad range of CNS indications, including major depressive disorder, neuropathic pain and L-DOPA-induced dyskinesia associated with Parkinson's disease. We are optimistic that we will be able to bring to market a new generation CNS medication that would help millions of patients currently treated with therapies with inadequate efficacy and significant side effects and safety concerns," stated H. Ralph Snodgrass, Ph.D., VistaGen's President and Chief Scientific Officer.

A research team at the University of Minnesota found a way to heal broken hearts.

Researchers used a 3D printer to create protein patches that mimic heart tissue to treat post-heart attack scars. The research is in collaboration with the University of Wisconsin-Madison and the University of Alabama-Birmingham.

Brenda Ogle, a University biomedical engineering professor and lead researcher for the project, said she and her team have investigated proteins that surround cells in the body for 15 years. The team has been studying how the proteins also called the extracellular matrix influence stem cell behavior.

For many years, weve been trying to develop optimum formulation that can support stem cells in new cardiac [cell] types, Ogle said, adding that theyve focused on cardiac cell types to figure out a way to strengthen them after the muscle cells are damaged and die during a heart attack. Its one of the cell types in the body that cant be recovered.

The team successfully treated mice with the patches and is now planning to test the method on larger animals.

Molly Kupfer, a doctoral student who is part of Ogles team, said a heart attack occurs when there is a blockage in a primary blood vessel that delivers oxygen and nutrients to the heart.

When that happens, you have cell death in the area of the heart that doesnt receive the appropriate oxygen and nutrients, Kupfer said. Those cells that die arent able to recover."

Typically, after a heart attack, the blood clot in the heart is removed at a hospital, and if the heart has not been damaged too badly, doctors monitor the heart long-term, prescribe medicine and regularly check for signs of heart failure, Ogle said.

What you get instead after a heart attack is scar tissue forming, and that scar tissue ultimately fails, Ogle said.

Associate Professor Brenda Ogle places a 3D printed biopatch on a mouse heart in Nils Hasselmo Hall on Tuesday, April 25, 2017. Her research team induces heart attacks in mice, which causes a dead area of cardiac cells. The patch is placed in this dead zone and mimics the cells of the native heart that aren't able to be replenished on their own.

Kupfer said she worked with Paul Campagnola and his lab at the University of Wisconsin to print the patches; the cells were prepared at the University of Minnesota.

Campagnola, a biomedical engineering professor, said he initially developed the underlying printing technology in 2000.

"The idea of the patch is it could actually behave like native cardiac tissue and assist the function of the heart, Kupfer said, adding that the method used to print the patches results in extremely high resolution structures.

Ogle said before applying the patch to the animal hearts theyre currently testing on, they take a scan of the scarred tissue and create a digital template for the 3D-printer to follow and print the proteins in the same pattern.

Campagnola said the patch provides a stable space for cells to grow and be implanted in damaged areas.

Cardiac cells are also added to the patch when it covers a damaged area. Ogle said it not only provides a support structure, but transplants healthy cells that will eventually become integrated into the heart, stabling it structurally and functionally.

A huge aha moment was when [the cardiac cells] started to beat on this patch synchronously and spontaneously, she said. When that happened, we realized that this could be a viable therapy for the heart, a way to replace those lost muscle cells.

Through the research group at the University of Alabama, Ogle said a study was conducted where the patch was tested on dead or dying tissue in mice hearts and the group saw improvement in the mice after four weeks.

The project was funded through a series of grants from the National Institutes of Health, the National Science Foundation with support from the University, she said.

The group has since received larger funds from the NIH to run a study using the patch on larger animals within the next year.

Ogle said it would take about 10 years until the patch can be used on human patients in a clinical setting.

Coalition Duchenne funded cardiosphere-derived cell studies in Duchenne carried out by Eduardo Marbn MD, the director of the Cedars-Sinai Heart Institute. This work was later licensed for commercial development by Capricor.

(PRWEB) April 25, 2017

Coalition Duchenne, a charity based in Newport Beach, California, committed to raising awareness for Duchenne muscular dystrophy, and funding for Duchenne research, congratulates Capricor Therapeutics on positive six-month results from its randomized CAP-1002 (cardiosphere-derived cells) Phase I/II HOPE clinical trial in Duchenne announced today.

Coalition Duchenne funded studies carried out by Eduardo Marbn MD, the director of the Cedars-Sinai Heart Institute, on cardiosphere-derived cells in Duchenne. This work was later licensed for commercial development by Capricor.

"We are excited that our work with Dr. Marbn is evolving and could become a treatment for Duchenne through Capricor's stellar efforts. It is the cardiomyopathy associated with Duchenne that causes us to lose so many boys and young men with Duchenne. Their hearts fail them when they still have so many dreams to be fulfilled. We must strengthen those hearts," said Catherine Jayasuriya, the founder and executive director of Coalition Duchenne.

The six-month results showed statistically-significant improvements in systolic thickening of the inferior wall of the heart and in the function of the middle and distal upper limb in patients treated with CAP-1002 as compared to control patients. In addition, differences observed in several other cardiac and skeletal muscle measures, including cardiac scar, were consistent with a treatment effect.

"These initial positive clinical results build upon a large body of preclinical data which illustrate CAP-1002's potential to broadly improve the condition of those afflicted by Duchenne, as they show that cardiosphere-derived cells exert salutary effects on cardiac and skeletal muscle," said Linda Marbn, PhD, Capricor's president and chief executive officer.

John L. Jefferies, MD, Professor of Pediatric Cardiology and Adult Cardiovascular Diseases at the University of Cincinnati and Director, Advanced Heart Failure and Cardiomyopathy, and Principal Investigator of the HOPE Trial, said, "In HOPE, we saw potential effects in both the heart and skeletal muscle that appear quite compelling in an exploratory trial."

Coalition Duchenne is hopeful that CAP-1002 will move forward rapidly and become a treatment for Duchenne. Such a development will realize a simple, but potentially game changing, lateral thought by a mother of a young man with Duchenne. Catherine's 24-year-old son Dusty Brandom has the cardiomyopathy exhibited by all boys and young men with Duchenne. In November 2011, Catherine read an Economist article titled "Repairing Broken Hearts" featuring the research of Dr. Eduardo Marbn and others. She immediately thought about Dusty's heart. Catherine's quest, both as a mother and a leader in the Duchenne community, became to convince the researchers to apply stem cell technology to Duchenne. She wrote to all of the researchers mentioned in the article and pushed her simple thesis that Duchenne related cardiomyopathy would be a good candidate for therapy. Only Dr. Eduardo Marbn responded.

About Duchenne muscular dystrophy

Duchenne muscular dystrophy is a progressive muscle wasting disease. It is the most common fatal genetic disease that affects children. Duchenne occurs in 1 in 3,500 male births, across all races, cultures and countries. Duchenne is caused by a defect in the gene that codes for the protein dystrophin. This is a vital protein that helps connect the muscle fiber to the cell membranes. Without dystrophin the muscle cells become unstable, are weakened and lose their functionality. Life expectancy ranges from the mid teenage years to age 30.

About CAP-1002

CAP-1002 consists of allogeneic cardiosphere-derived cells, or CDCs, a type of cardiac progenitor cell. CDCs have been the subject of over 100 peer-reviewed scientific publications and have been administered to approximately 140 human subjects across several clinical trials. CAP-1002 is currently being evaluated in the randomized, double-blind, placebo-controlled Phase II ALLSTAR Clinical Trial in adults who have suffered a large heart attack and in the Phase I/II HOPE Clinical Trial in boys and young men with Duchenne.

One of the finalists in the Governors Business Plan Contest, Cellular Logistics, is making another run at the top prize as it pursues commercialization of its biomaterials.

Two years ago, the company submitted a plan and made it to the semifinal round before being eliminated.

That was premature, but a good experience to go through in terms of preparation for this year, where we have a much more clear path and stronger team, said Adam Bock, CFO for Cellular Logistics. Weve been here before, but its always exciting.

The company just finished up a family and friends funding round last quarter, which raised $400,000. Its still in its growth stages, according to Bock, who characterizes Cellular Logistics as a virtual company at this point.

We have our business and tech team who operate wherever we need to be -- no dedicated office or lab, Bock said. All work has been done at Wisconsin Institute for Medical Research.

He added the company will be prepared to transition into a commercial space in about six months, saying were right at that crossover point.

Eric Schmuck, Cellular Logistics chief science officer, invented the companys patented biomaterials and heads the studies currently being done to test them.

He initially had the idea as a grad student in the UW-Madison Department of Physiology, where he was working with materials on which to grow stem cells. He realized the material he was experimenting with had unique characteristics which could be applicable in other ways.

It was novel; no one had done anything like it, Schmuck said. WARF agreed to patent the idea in 2011. Weve been tinkering with it in UW ever since.

The company is in the preclinical phase, currently testing an injectable supportive extracellular matrix in the hearts of mice. While results for these tests will have to wait until they are complete, Schmuck says that for earlier iterations, tests have been extremely promising.

He has seen really good restoration of function, with earlier tests, including powerful reduction in cardiac dilation -- a good sign for heart health.

In fact, earlier tests suggest the companys biomaterials are able to reverse or inhibit progression to heart failure, Schmuck says. They would be used in humans to repair damaged cardiac muscles, for patients who have experienced recent heart attacks or heart failure.

The company will be seeking approval from the FDA eventually, Schmuck said, adding that human trials could be undertaken in two or three years.

Bock says winning the contest would be spectacular, and that taking part is a lot of fun. The top 12, or Diligent Dozen, will be announced in late May, with the end of the contest coming in early June.

This week: Biomedical engineering division, University of Minnesota

Three-dimensional or 3D printing technology, which has been around for almost three decades, routinely makes headlines. Not surprising, given that the so-called Fabbers, or personal manufacturing machines3D printers come under this categorynow not only make jewellery and toothbrushes, but also football boots, racing-car parts, custom-designed cakes, guns, human organs, houses and plane parts.

3D printing can be used to save lives too. Consider this. During a heart attack, the muscle cells of the heart do not get enough blood. Hence, they die. Our bodies cant replace these dead cells, so the body leaves a scar tissue in that area of the heart. This puts the person at risk of heart failure in the future.

A team of biomedical engineering researchers, led by the University of Minnesota (Umn.edu), has created a laser 3D-bioprinted patch to address the issue and help heal the scarred heart tissue after a heart attack. Three-dimensional bioprinting is the process of creating cell patterns in a confined space using 3D printing technologies.

The researchers successfully used this technique to incorporate stem cells (cells capable of renewing themselves through cell division, sometimes after long periods of inactivity) derived from adult human heart cells in a dish in the lab.

When the cell patch was placed on a mouse following a simulated heart attack, the researchers saw significant increase in functional capacity after just four weeks. Since the patch was made from stem cells and structural proteins (that do most of the work in cells and are required for the structure, function, and regulation of the bodys tissues and organs) belonging to the heart, it became part of the heart and was absorbed into the body, requiring no further surgeries.

The discovery, which is a major step forward in treating patients with tissue damage after a heart attack, was published on 14 April in Circulation Research, the journal published by the American Heart Association. The researchers have filed a patent for it.

The scientists insist that this research is different from previous ones in that the patch is modelled after a digital, 3D scan of the structural proteins of the heart tissue. The digital model is made into a physical structure by 3D printing, further integrating cardiac cell types derived from stem cells. Only with 3D printing of this type, explain the researchers, can we achieve the 1 micron resolution needed to mimic structures of native heart tissue.

The scientists say they are already beginning the next step to develop a larger patch that they will test on a pig heart, which is similar in size to a human heart. Of course, the real success will be known only when human trials take place.

3D printing belongs to a class of techniques known as additive manufacturing, or building objects layer by layer. The most common household 3D-printing process involves a print head, which allows for any material to be extruded or squirted through a nozzle. There are several additive processes, including selective laser sintering, direct metal-laser sintering, fused deposition modelling, stereolithography and laminated-object manufacturing. All of them differ in the way layers are deposited to create the 3D objects.

Meanwhile, the concept of 4D printing, which allows materials to self-assemble into 3D structures, and was initially proposed by Skylar Tibbits of the Massachusetts Institute of Technology (MIT) in April 2013, is also showing promise.

According to the American Heart Association, heart disease is the No. 1 cause of death in the U.S. killing more than 360,000 people a year. During a heart attack, a person loses blood flow to the heart muscle and that causes cells to die. Our bodies cant replace those heart muscle cells so the body forms scar tissue in that area of the heart, which puts the person at risk for compromised heart function and future heart failure.

In this study, researchers from the University of Minnesota-Twin Cities, University of Wisconsin-Madison, and University of Alabama-Birmingham used laser-based 3D-bioprinting techniques to incorporate stem cells derived from adult human heart cells on a matrix that began to grow and beat synchronously in a dish in the lab.

Watch a video of the cells beating on the patch.

When the cell patch was placed on a mouse following a simulated heart attack, the researchers saw significant increase in functional capacity after just four weeks. Since the patch was made from cells and structural proteins native to the heart, it became part of the heart and absorbed into the body, requiring no further surgeries.

This is a significant step forward in treating the No. 1 cause of death in the U.S., said Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota. We feel that we could scale this up to repair hearts of larger animals and possibly even humans within the next several years.

Ogle said that this research is different from previous research in that the patch is modeled after a digital, three-dimensional scan of the structural proteins of native heart tissue. The digital model is made into a physical structure by 3D printing with proteins native to the heart and further integrating cardiac cell types derived from stem cells. Only with 3D printing of this type can we achieve one micron resolution needed to mimic structures of native heart tissue.

We were quite surprised by how well it worked given the complexity of the heart, Ogle said. We were encouraged to see that the cells had aligned in the scaffold and showed a continuous wave of electrical signal that moved across the patch.

Ogle said they are already beginning the next step to develop a larger patch that they would test on a pig heart, which is similar in size to a human heart.

The research was funded by the National Science Foundation, National Institutes of Health, University of Minnesota Lillehei Heart Institute, and University of Minnesota Institute for Engineering in Medicine.

3D-printed Patch Can Help Mend a 'Broken' Heart - Technology Networks

One of the problems with heart attacks (as if there weren't enough already) is that when the heart heals afterwards, it grows scar tissue over the part of the heart that was damaged. That scar tissue never does become beating heart tissue, so it leaves the heart compromised for the rest of the patient's life. There may be hope, however, as scientists from the University of Minnesota have created a new patch that allows the heart to heal more completely.

First of all, yes, this has been done before. We have already seen experimental "heart patches" from places like the University of Tel Aviv, Brown University and MIT, which allow the heart to heal with a minimum of scar tissue growth.

One of the things that makes this latest patch unique is the fact that it's 3D-bioprinted out of structural proteins native to the heart. It takes the form of a scaffolding-like matrix, which is subsequently seeded with cardiac cells derived from stem cells. The result is a patch of material, similar in structure and material to heart tissue, containing actual functioning heart cells as opposed to inert scar tissue.

In lab tests, one of the patches was placed on the heart of a mouse that had suffered a simulated heart attack. Within just four weeks, the scientists noted a "significant increase in functional capacity." The patch was ultimately absorbed by the body, so no additional surgeries were required to remove it after its job was done.

"We were quite surprised by how well it worked given the complexity of the heart," says associate professor Brenda Ogle, who is leading the research. "We were encouraged to see that the cells had aligned in the scaffold and showed a continuous wave of electrical signal that moved across the patch."

A larger patch is now in the works, which will be tested on a pig heart.

Other institutions involved in the study include the University of Wisconsin-Madison and University of Alabama-Birmingham. A paper on the research was recently published in the journal Circulation Research.

A female specimen of a zebrafish (Danio rerio) breed with fantails

Cardiovascular disease is one of the leading causes of death in the world with approximately 30% of global mortality attributed to it.Cardiovascular disease conditions lead to damage of cardiac muscle cells resulting in defective heart function.

Stem cell therapy, though a relatively young science, is one of the upcoming treatment options for such diseases in the near future. In principle, stem cells from embryos can be made to differentiate into many functional cell types including heart cells, which can be effectively used to replace damaged cells in heart patients. To achieve this, scientists are constantly trying to understand the developmental process by which the heart is formed from various progenitors in a growing embryo. Once we understand this pathway at an organismal level, efforts can be made to use these stem cells for regenerative medicine.

A team of scientists led by Bruno Reversade from Singapore and Ian Scott from the University of Toronto have come together to study heart development in the Zebrafish model.

Zebrafish, scientifically called Danio rerio, is one of the powerful models for studying various organ functions. Although there are major structural differences between zebrafish and humans, there are strong similarities at the genetic and morphological levels. One of the biggest advantages of using zebrafish is that unlike mice, rats or monkeys, zebrafish embryos are transparent and hence provide a tractable system for visualizing these important developmental processes in situ.

During embryonic development, early heart development requires the activation of one of the important signaling pathways called Nodal or TGF pathway. Depending on the activation levels of Nodal, different cells become different stem cell types. Hence, there has to be a mechanism for fine-tuning of this signaling to produce these activity thresholds. Scientists from these two groups have recently identified the candidates involved in this fine-tuning.

Researchers recently identified a mutation, which leads to zebrafish with no heart at all. This suggests that this mutation somehow alters an early developmental process in heart formation. Interestingly, this gene encodes for a protein called Apelin receptor. So how does the Apelin receptor affect heart development? Scientists revealed that mutation in this receptor caused lower levels of Nodal signaling in mutant embryos as compared to the normal ones, thus failing to induce the formation of cardiac stem cells. When Nodal activity is artificially elevated in embryos that lack the Apelin receptor, they were able to develop hearts further confirming the role of Apelin receptor in this pathway.

A detailed understanding of this molecular cross-talk could help in the derivation of specific cell types from human embryonic stem cells for regenerative medicine, says Bruno Reversade, a human geneticist at the A*STAR Institute of Medical Biology, who co-led the investigation.

Further, this collaborative study showed that the Apelin receptor does not work in cells that produce or receive Nodal signals, suggesting that the Apelin receptor modulates Nodal signaling levels by acting in cells that lie between the cells that release Nodal signals and the cardiac progenitors.

In brief, this receptor functions as a distant regulator for fine-tuning the expression of the Nodal pathway during early stages of heart development ensuring proper cardiac development. One important area of future study is to determine whether modulating the levels of this receptor can prove useful for patients with various heart disorders.

MINNEAPOLIS/ST. PAUL A team of biomedical engineering researchers, led by the University of Minnesota, has created a revolutionary 3D-bioprinted patch that can help heal scarred heart tissue after a heart attack. The discovery is a major step forward in treating patients with tissue damage after a heart attack.

The research study was published Apr. 14 inCirculation Research, a journal published by the American Heart Association. Researchers have filed a patent on the discovery.

According to the American Heart Association, heart disease is the No. 1 cause of death in the U.S. killing more than 360,000 people a year. During a heart attack, a person loses blood flow to the heart muscle and that causes cells to die. Our bodies cant replace those heart muscle cells so the body forms scar tissue in that area of the heart, which puts the person at risk for compromised heart function and future heart failure.

In this study, researchers from the University of Minnesota-Twin Cities, University of Wisconsin-Madison, and University of Alabama-Birmingham used laser-based 3D-bioprinting techniques to incorporate stem cells derived from adult human heart cells on a matrix that began to grow and beat synchronously in a dish in the lab.

When the cell patch was placed on a mouse following a simulated heart attack, the researchers saw significant increase in functional capacity after just four weeks. Since the patch was made from cells and structural proteins native to the heart, it became part of the heart and absorbed into the body, requiring no further surgeries.

This is a significant step forward in treating the No. 1 cause of death in the U.S., said Brenda Ogle, an associate professor of biomedical engineering at the University of Minnesota. We feel that we could scale this up to repair hearts of larger animals and possibly even humans within the next several years.

The digital model is made into a physical structure by 3D printing with proteins native to the heart and further integrating cardiac cell types derived from stem cells. Only with 3D printing of this type can we achieve one micron resolution needed to mimic structures of native heart tissue.

We were quite surprised by how well it worked given the complexity of the heart, Ogle said. We were encouraged to see that the cells had aligned in the scaffold and showed a continuous wave of electrical signal that moved across the patch.

Ogle said they are already beginning the next step to develop a larger patch that they would test on a pig heart, which is similar in size to a human heart.

The research was funded by the National Science Foundation, National Institutes of Health, University of Minnesota Lillehei Heart Institute, and University of Minnesota Institute for Engineering in Medicine.

3D-Printed Patch Can Help Mend a 'Broken' Heart - Lab Manager | News (press release) (blog)

BROOMFIELD, Colo., April 17, 2017 /PRNewswire/ -- "Interventional orthopedics in pain medicine practice" was recently published by Elsevier as a chapter in Techniques in Regional Anesthesia and Pain Management. The chapter, authored by Regenexx founder Christopher J. Centeno, MD examines less invasive ways to treat orthopedic pain and injuries through autologous biologics, such as stem cells and platelet rich plasma (PRP), and the shift from surgical orthopedics to interventional orthopedics.

Interventional orthopedics utilizing advanced technologies, such as ultrasound and X-ray guidance, precise percutaneous injections of autologous biologics, and bone marrow concentrate, (BMC) expand nonsurgical options in the field of orthopedics. Citing the dramatic reduction in cardiac surgery rates since the adoption of the specialty interventional cardiology, the authors reveal, "We are poised on the brink of the same change in orthopedic care." The authors also state, "The field of autologous biologics has the potential to alter the playing field of orthopedic care by allowing percutaneous injections to replace the need for more invasive orthopedic surgeries."

The chapter covers three important tenets in the developing field that will allow Interventional Orthopedics to alter traditional orthopedic care in the future. First is the rapid expansion of injectates (material being injected), such as stem cells and PRP, that can help heal damaged tissue and that can effectively treat musculoskeletal tissues. Second is the precise image-guided placement of those injectates into those damaged tissues. And third is the development of new tools that will advance this regenerative-medicine technology. The chapter also highlights research that supports the use of bone marrow stem cells and the importance of education standards and organization, training, and retraining of physicians to meet these standards.

The full chapter "Interventional orthopedics in pain medicine practice" can be found online at http://www.sciencedirect.com/science/article/pii/S1084208X16300052.

Christopher J. Centeno, MD, is the CEO of Regenexx and an international expert and specialist in regenerative medicine and the clinical use of mesenchymal stem cells in orthopedics. Dr. Centeno maintains an active research-based practice and has multiple publications listed in the US National Library of Medicine.He has also served as editor-in-chief of a medical research journal dedicated to traumatic injury and is one of the few physicians in the world with extensive experience in the culture expansion of and clinical use of adult stem cells to treat orthopedic injuries.

Q. Im in doubt regarding myelodysplasia is it multipotent or pluripotent?

A. Thats a great question because it lets us talk about hematopathology (yay!) and also stem cells (which can be confusing unless someone explains some simple stuff).

What is a stem cell? First, lets talk about stem cells. The thing that makes a stem cell a stem cell, at least in my mind, is the ability to self-renew. This means that the stem cell can either divide into two daughter cells which will mature into grown up cells, or (and more commonly) it can give rise to two cells: one that will become a mature cell, and another which retains the capacity to divide again. Its called asymmetric division: instead of giving rise to two of the same cells, you get one regular cell and another stem cell (which can continue this cycle of replication for a long long time).

(Virtually) limitless replication Most cells have a limited number of times that they can divide. This is because the telomeres (little protective DNA sequences) on the end of the chromosomes get a little shorter every time the DNA replicates and eventually they are so short that they cant protect the DNA and the cell is unable to divide. Stem cells and cancer cells have an enzyme called telomerase that replenishes the telomeres, keeping them nice and long so the cell can keep on dividing. Stem cells do eventually die so technically, there are a limited number of cell divisionsbut its a really, really big number. Cancer cells, on the other hand, are often totally immortal they can just keep on dividing and dividing.

Totipotent Another cool thing about stem cells is that they can give rise to many different kinds of cells. Heres where things can get murky. There are stem cells in an embryo which are able to give rise to any of the cell types in the body: hepatocytes, epithelial cells, neurons, cardiac muscle cellseverything. This makes sense: if youre going to grow into a human, you have to have cells that give rise to all the necessary cell types. These stem cells are called totipotent or pluripotent stem cells. Theres a slight difference between the two words: totipotent means that the stem cell can give rise to any and all human tissue cells and it can even give rise to an entire functional human. The only totipotent cells in human development are the fertilized egg and the cells in the next few cell divisions.

Pluripotent After those few cell divisions, the cells become pluripotent. Pluripotent cells are similar to totipotent cells in that they can give rise to any and all human tissue cells. Theyre different, though, because they are not capable of giving rise to an entire organism. On day four of development, the tiny little embryo forms two layers: one that will become the placenta and the other that will become the baby. The cells that will become the baby can give rise to any human tissue type (obviously) but those cells alone cant give rise to the entire organism (because you cant form the baby without the placenta). Slight difference but enough to make a separate term.

Multipotent Another term you should know is multipotent. Multipotent stem cells cannot give rise to any old cell in the body they are restricted to a limited range of cell types. For example, there are multipotent stem cells in the bone marrow that can give rise to red cells, white cells and platelets. They cant give rise to hepatocytes, or any other cell type, though so they are not totipotent or pluripotent.

There are lots of multipotent stem cells in the adult human body. They reside in the bone marrow, skin, muscle, GI tract, endothelium, and mesenchymal tissues. This means that there is a nice source for replacing cells that have died or been sloughed away.

What about myelodsyplasia? So back to your question. Myelodysplasia is a hematopoietic disorder in which cells in the bone marrow grow funny (dysplasia) they might be binucleate, or not have the normal number of granules, or whatever. In addition, some cases have an increase in blasts in the bone marrow but not over 20%, or youd call it an acute leukemia. Some cases transform, eventually, into an acute myeloid leukemia; others just stay the way they are and dont become nasty.

Check out the image above, from a case of myelodysplasia. There is a bizarre, multinucleated erythroblast at 11 oclock (this is called dyserythropoiesis, or disordered red cell growth). There are also two messed-up neutrophils (dysgranulopoiesis) at 4 oclock and 10 oclock the one at 4 oclock has only two nuclear lobes, and both are hypogranular (not enough specific granulation). Theres also an increase in blasts, if this field is representative: theres one in the middle and (probably) one at 5 oclock.

This disorder (actually, its a group of disorders) involves stem cells in the bone marrow. Sometimes only one cell line is involved (red cells, say); other times all three cell lines are involved (red cells, white cells and platelets). Either way, the disorder involves a stem cell, and since the stem cells in the bone marrow are multipotent, it would be correct to say that myelodysplasia is a disorder of multipotent stem cells in the bone marrow. Its kind of redundant, though, because as far as we know, there arent any other kind of stem cells in the bone marrow! But at least you know the answer to your question now.
