iPS cells may help halt failing vision

By Andy Coghlan

A woman in her 80s has become the first person to be successfully treated with induced pluripotent stem (iPS) cells. A slither of laboratory-made retinal cells has protected her eyesight, fighting her age-related macular degeneration a common form of progressive blindness.

Such stem cells can be coaxed to form many other types of cell. Unlike other types of stem cell, such as those found in an embryo, can be made from adult non-stem cells a discovery that in 2012.

Now, more than a decade after they were created, these stem cells have helped someone. at the RIKEN Laboratory for Retinal Regeneration in Kobe, Japan, and her team took skin cells from the woman and turned them into iPS cells. They then encouraged these to form retinal pigment epithelial cells, which are important for supporting and nourishing the retina cells that capture light for vision.

The researchers made a slither of cells measuring just 1 by 3 millimetres. Before in 2014, they first removed diseased tissue on her retina that was gradually destroying her sight. They then inserted the small patch of cells they had created, hoping they would become a part of her eye and stop her eyesight from degenerating.

Now the results are in. Published today, they show that the treatment hasnt made the womans vision any sharper, but it does seem to have prevented further deterioration with her vision now stable for more than two years. Since the graft, the woman says her vision is brighter.

Takahashi and her team have done incredible work, and deserve all the praise they get for this project, says , director of the Center for iPS Cell Research and Application at Kyoto University, who won the Nobel prize for and collaborated on this work. This is a landmark study and opens the door to similar treatments for many diseases, he says.

This first iPSC-derived retinal graft is an important landmark in the field of retinal regeneration, says at University College London, and head of a trial at Moorfields Eye Hospital in London of similar grafts made instead from human embryonic stem cells.

One worry about this approach is that turning the stem cells into new tissues could lead to cancer-causing genetic mutations though the team found no evidence of this in the treated woman. However, a trial of the technique in another person was cancelled in 2015, after tests revealed that the cells intended to be given to the man had developed genetic abnormalities.

But although it has taken many years to bring , many private centres around the world have been advertising unregulated treatments purporting to use stem cells for some time.

A second study published today shows just how badly some unregulated treatments described as stem cell therapies can go wrong. Three case reports of women given such treatments for age-related macular degeneration detail how one woman went blind and the vision of the other two became much worse.

All three ended up seeking emergency treatment in 2015, after each paid $5000 to a private clinic to receive injections of their own fatty tissue into their eyes.

Patients and physicians in the US should be made aware that not all stem cell clinics are safe, and that stem therapy as provided in private clinics in the US is unproven and potentially harmful, says at the University of Miamis Bascom Palmer Eye Institute, Florida, who subsequently treated two of the women.

Albini advises people to be suspicious of any procedure involving payment. Most legitimate research in the US does not require patients to pay for the experimental procedures, he says, adding that people should check whether a trial has been registered with the US Food and Drug Administration. Be aware that if it sounds too good to be true, it may indeed not be true.

The idea of a cell therapy for Parkinsons disease starts out simple: Symptoms of the progressive disease are largely driven by the deaths of dopamine-producing neurons found deep within the brain. With lower levels of the neurotransmitter come the characteristic tremors, rigidity and slow movements.

By replacing those lost nerve cells with new dopamine producers, researchers hope to renew the brains connection to the bodys muscles and improve a persons overall motor function.

But in the brain, everything becomes more complicated. On top of the risk of immune system rejection that comes with any kind of living tissue transplant, its important to make sure the implanted cells function correctly and do not pick up any dangerous genetic mutations as they grow.

How ICON, Lotus, and Bioforum are Improving Study Efficiency with a Modern EDC

CROs are often at the forefront of adopting new technologies to make clinical trials more efficient. Hear how ICON, Lotus Clinical Research, and Bioforum are speeding database builds and automating reporting tasks for data management.

Now, a new company, Aspen Neuroscience, aims to tackle both obstacles at once.

First, the startup hopes to avoid any harmful immune reactions by using a patients own cells as a starting point. Then, Aspen plans to implement a rigorous quality control program employing whole genome sequencing and artificial intelligence to make sure the cells stay in line as theyre processed and readied for the procedure.

And to do it, the San Diego-based company is starting out with $6.5 million in seed money plus an impressive roster of names.

They are led by neurology researcher Howard Federoff, previously vice chancellor for health affairs and CEO of the University of California, Irvine health system as well as the executive dean of medicine at Georgetown University. Hes joined by Aspen co-founder and stem cell scientist Jeanne Loring, founding director and professor emeritus of the Center for Regenerative Medicine at the Scripps Research Institute.

Meanwhile, the seed round was led by Domain Associates and Axon Ventures with additional backing from Alexandria Venture Investments, Arch Venture Partners, OrbiMed and Section 32.

Aspen looks to combine its expertise in stem cell biology, genomics and neurology to offer the first autologous cell therapy for Parkinsons diseasewhile others in the space have pursued allogeneic routes, or therapies derived from donors other than the patient.

The process starts with a culture of the patients skin cells, which are then genetically induced to become pluripotent stem cellsor cells capable of differentiating into any other cell type in the body. These are then chemically nudged further to transform into precursor versions of the dopamine-producing neurons, which are typically found in the midbrain and regions responsible for the movement of limbs.

We can say without any equivocation that we can produce the population of cells necessary to transplant, and in a short enough period of time to have a potential beneficial impact on the evolution of the disease, said Federoff, who has also served as chair of the NIHs Recombinant DNA Advisory Committee and helped lead the U.S. Parkinsons Disease Gene Therapy Study Group.

We envisage that this will set back the clock on patients who have Parkinsons, unlike any other therapy that we know of, he told FierceMedTech in an interview.

The number of cells needed would be much smaller compared to other cell therapies and cancer treatments. The healthy human brain contains only about 200,000 dopamine-producing nerve cells, split between its two hemispheres, while patients with Parkinsons disease have lost about 50% or more of those neurons.

Aspen aims to evaluate two doses: one that aims to replace about 60% to 65% of a persons normal cell complement and another larger treatment, Federoff said.

Those smaller doses, as well as starting with a patients donor cells, help make the treatment safer to produce by requiring fewer steps. Each cycle of cell division and multiplication to increase their numbers carries the risk of introducing genetic mutations.

As the cells are grown, they are consistently evaluated with data-driven techniques pioneered by Lorings laboratory. Using whole genome RNA sequencing, Aspen will match the cells up at every stage with a genetic barcode taken from each patient at the start. This will allow them to look for changes, duplications or deletions in the pluripotent stem cell genome.

If the cells harbor mutations that are cancer drivers, we don't want to put those into people, Loring said. The only way is to check the sequencing before we transplant them.

The cells used in the transplant procedure arent fully grown; as neuron progenitors, they mimic the development steps seen in the brain of a growing fetus after theyre placed in the body as they wire themselves up to other neural structures and begin to form new networks of their own.

We anticipate that they will manufacture and release dopamine in a manner that is consistent with synaptic neurotransmission and the process of communicating from cell-to-cell, said Federoff. They will take up dopamine from synapses when it has done its business, bring it back into the cell, and prepare it for another synaptic release.

These are not just dopamine pumps, theyre real neurons, added Loring. They will genuinely replace the cells that have been lost in every way.

Aspen plans to pursue two courses of therapy, for the two major types of Parkinsons disease. Their lead candidate is for idiopathic, or sporadic Parkinsons, while their second is a CRISPR-edited version of the therapy designed to address one of the diseases most common genetic mutations, linked to about 5% of cases.

This would not only aim to restart dopamine production in this orphan indication, but also restore the damaged enzyme GBA, which is seen as an underlying cause. Federoff and Loring expect their sequencing-based quality check system will also help catch any off-target edits linked to the use of CRISPR-Cas9.

The company has yet to secure permission from the FDA to officially launch clinical trials, but the agency has signed off on Aspens plans to prepare a trial-ready cohort of Parkinsons disease patients in the meantime. This would include the initial stages of recruitment and testing, including the selection of patients capable of having their skin cells made into pluripotent stem cells.

After it receives its go-ahead from the FDA, Aspen plans to hit the ground running,enrolling at least 176 participants in a phase 1/2 study that includes a randomized stage to determine clinical benefits.

By turning stem cells into brain cells, Aspen Neuroscience hopes to rewind the progress of Parkinson's disease - FierceBiotech

A Campus meeting in November reviewed the arguments for and against donor conception, and the sometimes difficult ethical arguments raised by the prospect of a donor-conceived child. 'Artificial' sperm cells derived from testicular tissue or stem cells may resolve some of those arguments.

The problem is especially acute in cancers diagnosed in prepubertal boys in whom there are no sperm cells available for storage. Their only option for future fatherhood in the face of cancer treatment is adoption or donor sperm. And this, added Goossens, is not an exceptional problem. Incidence rates are around 17 cases per 100,000 population, with leukemia and CNS tumours the most commonly diagnosed. So the usual pathway to fertility preservation in these young cases is for the oncologist to warn of the risk to future fertility from the cancer treatments and refer to the fertility clinic. Biopsy of testicular tissue, of course, must be performed before any radio- or chemotherapy.

Goossens described two experimental techniques, spermatogonial stem cell retrieval and transplantation, and homotopic tissue grafting. The danger in the former procedure is a risk of introducing malignancy, so banked tissue must be free of malignant contamination. Experiments in mouse-to-mouse models have demonstrated spermatogenesis from tissue grafting, and most recently fully functional conception and delivery in a non-human primate (Grady). Similarly, experiments in mouse models with spermatogonial stem cell transplantation have so far proved efficient, with spontaneous pregnancy already possible.

Of course, the objective of this impressive experimental work is not merely a resolution to the question of genetic continuity in couples faced with third-party donation, but the future fertility and long-term quality of life of so many unfortunate young boys. Advances in cancer treatment have led to the increased survival of all children with cancer, and with it a new imperative for the restoration of their fertility. Not all cancer treatments cause complete testicular damage, but around one-third of children having treatment for pediatric cancers will end up infertile. Following the proof-of-concept study which saw the birth of Grady - in which testicular samples removed from prepubertal monkeys was frozen, thawed and regrafted under scrotal skin - the research group declared that their next logical step, with safety and feasibility apparent, is human trials.

KRAS mutations occur in approximately 20% of people with non-small cell lung cancer, and some previous studies have suggested that these mutations are associated with a poorer response to treatment, said Dr. Jonathan Cheng, vice president, oncology clinical research, Merck Research Laboratories. It was therefore encouraging to see in this exploratory analysis that KEYTRUDA monotherapy was associated with a survival benefit in certain patients with metastatic nonsquamous non-small cell lung cancer, regardless of KRAS mutational status.

The objective of the exploratory analysis was to assess the prevalence of KRAS mutations and their association with efficacy in the KEYNOTE-042 trial. Of the 1,274 untreated patients with metastatic nonsquamous NSCLC whose tumors expressed PD-L1 (TPS 1%) enrolled in KEYNOTE-042, 301 patients had KRAS evaluable data (n=232 without any KRAS mutation; n=69 with any KRAS mutation, including n=29 with the KRAS G12C mutation). Tissue tumor mutational burden (tTMB) and KRAS mutational status were determined by whole-exome sequencing (WES) of tumor tissue and matched normal DNA (blood). Patients were randomized 1:1 to receive KEYTRUDA 200 mg intravenously every three weeks (Q3W) (n=637) or investigators choice of chemotherapy (pemetrexed or paclitaxel) (n=637). Treatment continued until progression of disease or unacceptable toxicity. The primary endpoint was OS with a TPS of 50%, 20% and 1%, which were assessed sequentially. The secondary endpoints were PFS and ORR.

Findings from this exploratory analysis showed that KEYTRUDA monotherapy was associated with improved clinical outcomes, regardless of KRAS mutational status, in patients with metastatic nonsquamous NSCLC versus chemotherapy. In this analysis, KEYTRUDA reduced the risk of death by 58% (HR=0.42 [95% CI, 0.22-0.81]) in patients with any KRAS mutation and by 72% (HR=0.28 [95% CI, 0.09-0.86]) in patients with the KRAS G12C mutation compared to chemotherapy. The safety profile of KEYTRUDA was consistent with what has been seen in previously reported studies among patients with metastatic NSCLC.

Additional efficacy results from this exploratory analysis showed:

KEYNOTE-189 was conducted in collaboration with Eli Lilly and Company, the makers of pemetrexed (ALIMTA).

About Lung Cancer

Lung cancer, which forms in the tissues of the lungs, usually within cells lining the air passages, is the leading cause of cancer death worldwide. Each year, more people die of lung cancer than die of colon and breast cancers combined. The two main types of lung cancer are non-small cell and small cell. Non-small cell lung cancer (NSCLC) is the most common type of lung cancer, accounting for about 85% of all cases. Small cell lung cancer (SCLC) accounts for about 10 to 15% of all lung cancers. Lung cancer can also be characterized by the presence of different biomarkers, including PD-L1, KRAS, ALK, EGFR and ROS1. KRAS mutations occur in about 20% of NSCLC cases. Between 2008 and 2014, the five-year survival rate for patients diagnosed in the U.S. with advanced NSCLC was only 5%.

About KEYTRUDA (pembrolizumab) Injection, 100mg

KEYTRUDA is an anti-PD-1 therapy that works by increasing the ability of the bodys immune system to help detect and fight tumor cells. KEYTRUDA is a humanized monoclonal antibody that blocks the interaction between PD-1 and its ligands, PD-L1 and PD-L2, thereby activating T lymphocytes which may affect both tumor cells and healthy cells.

Merck has the industrys largest immuno-oncology clinical research program. There are currently more than 1,000 trials studying KEYTRUDA across a wide variety of cancers and treatment settings. The KEYTRUDA clinical program seeks to understand the role of KEYTRUDA across cancers and the factors that may predict a patients likelihood of benefitting from treatment with KEYTRUDA, including exploring several different biomarkers.

Materials science company W. L. Gore & Associates Inc. (Newark, DE) has announced a joint venture with the Mayo Clinic (Rochester, MN) to further develop a therapeutic system using stem cells and bio-absorbable scaffolds to treat a condition affecting patients with Crohns disease. Avobis Bio, based in Delaware, will draw on the expertise of scientists and medical professionals from both organizations to build on the encouraging results of an investigational treatment for perianal fistulas.

A debilitating condition that affects patients with Crohns disease, perianal fistulas are painful tunneling wounds connecting the anus to the skin, explained Gore in a press release. Few healing options exist, and patients endure multiple surgeries and ongoing risk of life-threatening complications, said Gore.

"Perianal fistulas are truly life-altering for Crohn's patients, and treatment options have eluded gastroenterologists and surgeons for years," added William Faubion Jr., MD, a Mayo Clinic gastroenterologist who specializes in inflammatory bowel diseases.

The innovative treatment involves harvesting a patients own mesenchymal stem cells, which then are populated on Gore's bioabsorbable polymer scaffold and surgically implanted in the fistula. A phase I clinical trial showed that 76% of patients healed within a year. If this outcome is validated in a larger trial, Gore said that it would dramatically exceed outcomes achieved with existing treatments.

This project is the initial focus of Avobis Bio, which describes its overall mission as an exploration of the use of mesenchymal stem cells combined with enabling bioabsorbable scaffolds that enhance the effectiveness of the cells in stimulating the body to heal.

Delivering a patients mesenchymal stem cells on a synthetic scaffold that biodegrades over time may be a first-of-its-kind medical therapy, noted Joe Carlson, a reporter at the Minneapolis-based Star Tribune reporting on the joint venture. If successful, Avobis Bio may one day offer a variety of tissue and organ-repair therapies combining Mayo's stem cell expertise and Gore's medical materials, he wrote.

Gore is perhaps best known to the public for its Gore-Tex outerwear, but the privately held $3.7 billion engineering and manufacturing firm sells products in an array of industries, including a line of medical devices designed to repair nonnatural holes in body organs, added Carlson. Mayo has used Gore-made devices for many years.

This article highlights some of the most recent drug target discoveries that could be used to develop and design a treatment for pancreatic cancer.

Scientists investigating pancreatic cancer have identified new targets which, with further research, could be the basis for developing future therapies. Listed below are five of the most recent target discoveries, in order of their journal publication dates, with the newest first.

Scientists at the Queen Mary University of London, UK and Zhengzhou University, China have developed a personalised vaccine system that may be able to delay the onset of pancreatic cancer.

Cells taken from mice, mutated chemically into pancreatic cancer cells and then infected with Adenovirus (AdV) as a prime or Vaccinia virus (VV) as a boost, create a vaccine product. The virus kills the cancerous cells in such a way that their antigens are released and are therefore able to prime the immune system to prevent pancreatic cancer returning.

Injection of the virus-infected cells into mice destined to develop pancreatic cancer doubled their survival rate, compared to their unvaccinated counterparts. The vaccine also delayed the onset of the condition in these mice.

Using cells from the recipient of the vaccine enables the immune system to respond to the exact antigens seen in tumour cells of the individual, resulting in a vaccine regime tailored to them.

Through this international collaboration, we have made progress towards the development of a prophylactic cancer vaccine against pancreatic cancer, said Professor Yaohe Wang, leader of the study, from Queen Mary University of London and the Sino-British Research Centre at Zhengzhou University in China.

Researchers at Sanford Burnham Prebys Medical Discovery Institute in the US have identified that a combination of two anti-cancer compounds, already approved for use to treat other cancers, shrank pancreatic tumours in mice.

Our study identifies a potential treatment combination that can immediately be tested against these aggressive tumours. We are already meeting with oncologists at Oregon Health & Science University, US to discuss how to advance this discovery into clinical evaluation, explained Dr Zeev Ronai, a professor in Sanford Burnham Prebys Tumor Initiation and Maintenance Program, also senior author of the study.

Scientists used L-asparaginase to starve pancreatic tumours of asparagine, an amino acid required by cells for protein synthesis. However, the tumour cells did not die, instead switching on a stress response pathway whereby they could produce asparagine themselves. Scientists then used an MEK inhibitor to block the stress response pathway, causing the pancreatic tumour to shrink.

L-asparaginase is already US Food and Drug Administration (FDA) approved to treat leukaemias and similarly the MEK inhibitor is approved for the treatment of solid tumours, including melanoma skin cancer.

This research lays the basis for the inhibition of pancreatic tumour growth by a combined synergistic attack based on asparagine restriction and MAPK signalling inhibition, says Dr Eytan Ruppin, chief of the Cancer Data Science Library at the National Cancer Institute (NCI) and co-author of the study.

Scientists from the Max Planck Institute for Biology of Ageing, Germany have identified that YME1L, a protease in the membrane of mitochondria, is activated when a cell uses glycolysis to produce energy anaerobically.

scientists were able to reduce tumour growth by switching off the glycolysis signalling pathway in the mitochondria

Cells adapt to oxygen deficiency by switching their energy supply to glycolysis, which ferments sugar without oxygen. This switch is often necessary in old age, as the cells in the body become poorly supplied with oxygen and nutrients.

Cancer cells can also face this problem; prior to angiogenesis, tumours are poorly perfused and so the tissue is deprived of oxygen. Oxidative stress in tumours drives the switch-on of multiple pathways. This includes the glycolysis pathway that alters the behaviour of the mitochondria to provide tumour cells with energy despite being starved of oxygen.

Scientists found that the YME1L protease is activated during the conversion to glycolysis. YME1L appears altered and breaks down various proteins in the organelles, preventing the formation of new mitochondria and causing the remaining organelles to change their metabolism. This process eventually stops as YME1L begins to degrade itself at high activity.

Researchers examined cancer cells originating from patients with pancreatic tumours and were able to reduce tumour growth by switching off the glycolysis signalling pathway in the mitochondria, with reproducible results both in the petri dish and in pancreatic tumours in mice.

There is currently no treatment available for pancreatic cancer. I believe that this protease can be a very interesting therapeutic target because we have seen that the signalling pathway is also active in human patients with pancreatic cancer, explained Thomas Langer, the Max Planck Director, continuing: However, there are no known substances that have an effect on this protease.

Researchers at the Crick Institute have identified cancer stem cells as a driver of pancreatic cancer growth. These cells can metastasise and differentiate into different tumour types to continue the spread of cancer.

Cancer stem cells appear at all stages of cancer growth so being able to identify where they are present could be vital in both targeting cancer and developing new treatments, according to the researchers. Analysis of gene expression in the cancer stem cells identified a protein, CD9, is present on tumour surfaces during development and when it is more established. This protein could therefore be used as a marker to help locate these cells.

A further development of the study established that this protein is not just a marker of cancer stem cells, but also promotes their malignant behaviour. By altering the amount of CD9 in tumour cells in mice, researchers found that reduced levels of this protein caused smaller tumours to form and increasing levels of CD9 created more aggressive cells able to form large tumours quickly.

These cells are vital to pancreatic cancer and if even just a few of them survive chemotherapy, the cancer is able to bounce back. We need to find effective ways to remove these cells and so stop them from fuelling cancer growth. However, we need more experiments to validate the importance of CD9 in human pancreatic cancer, says Victoria Wang, lead author and member of the Adult Stem Cell Laboratory at the Crick Institute.

A look into cancer stem cell metabolism also revealed CD9 increases the rate tumour cells take up glutamine, an amino acid which helps provide energy for cancer growth.

Now we know this protein is both linked to cancer stem cells and helps cancer growth, this could guide the development of new treatments that are targeted at the protein and so cut off the supply of glutamine to cancer stem cells, effectively starving the cancer, says Axel Behrens, corresponding author and group leader in the Adult Stem Cell Laboratory at the Crick Institute.

Scientists at Tel Aviv University, Israel have found that PJ34, a small molecule, causes human pancreatic cancer cells to self-destruct. The researchers tested PJ34 on xenografts (transplants) of human pancreatic tumours in mice.

this mechanism also exists in other types of cancer and therefore the treatment could be valuable for use on those resistant to current therapies

The mice were treated with a molecule called PJ34, which is permeable in the cell membrane but affects human cancer cells exclusively. This molecule causes an anomaly during the duplication of human cancer cells, provoking their rapid cell death. Thus, cell multiplication itself resulted in cell death in the treated cancer cells, explains Professor Malca Cohen-Armon, project lead at Tel Aviv Universitys Sackler Faculty of Medicine.

The treatment consisted of daily PJ34 injections for 14 days and four weeks later there was a relative drop of 90 percent in the number of cancer cells within the tumours of the mice. Cohen-Armon also noted there were no adverse side-effects observed in the mice.

This mechanism similarly exists in other types of cancer and therefore the treatment could be valuable for use on those resistant to current therapies. The molecule PJ34 is being tested in pre-clinical trials according to FDA regulations before clinical trials begin.

Five recent drug target discoveries for pancreatic cancer - Drug Target Review

Skin Stem Cells Comments Off on Five recent drug target discoveries for pancreatic cancer – Drug Target Review | December 12th, 2019

Im hairythats just fact, and its something Ive always been aware of. Ill never forget being in summer camp as a kid, wearing shorts every day and becoming very aware that my legs were much hairier than those of the girls around me. Now, Im no longer ashamed of being hairyIve actually come to embrace it. But in the past two decades, Ive gotten very acquainted with epilators, including laser hair removal.

I got my first laser hair removal treatment two years ago. It seemed like everyone was getting it done, but as a black woman, I knew I wasnt everyone. For brown skin, laser hair removal isnt a spur-of-the-moment decision, a process that should be approached through a Groupon or the local nail salon (yes, some nail salons actually perform laser hair removal). For us, the process can be a bit more expensive and tedious, and should be approached with the utmost caution.

Why? Well, lasers target pigment, and due to the high content of melanin in our skin, risks of discoloration and hyper-pigmentation are astronomically higher. So thats why, according to Chris Karavolas, owner of Romeo And Juliette Laser Hair Removal, darker skin requires a completely different laser all together, and operators with much more experience. Darker skin complexions need to be careful because not all centers have the right lasers for dark skin, and even if they do they do, many do not have enough experience in treating dark skin, he says.

When it comes to those specialized lasers, there are two options. Its important to treat with an Nd:YAG laser, such as the Candela GentleYAG or GentleMax Pro, says Anne Chapas, M.D., medical director of Union Square Laser Dermatology in New York City. The wavelength of a YAG laser goes deeper into the skin than a diode laser and is less absorbed by the surrounding skin pigment, so it more successfully treats the stem cells of the hair follicle. Additionally, more treatments may be required than for fairer skin: Expect to receive at least six sessions, Chapas says.

Knowing all these things, I went into laser hair removal with cautious optimism. I chose to treat my Brazilian areayears of improper hair removal had left me with ingrown and severe discoloration, to the point that my wax lady refused to continue treating me because my skin had gotten so irritated. I was sure that I wanted to continue being hair-free down there, so I decided to get laser hair removal on my vagina area. I was nervous heading into my first appointment, so I made sure to ask the aesthetician at Romeo & Juliette in-depth questions about her experience with dark skin, as well as requesting to see photos of previous clients and inquiring about a patch test. Then, it was showtime.

I like to think that I have a pretty high pain tolerance. However, laser removal certainly made me question that belief. I wont lie and say that it didnt hurt. It did. It felt like being snapped, hard, by rubber bands, but it was quick, and the results I saw were almost immediate. I was advised to shave right before the treatment, in order to give the laser immediate access to the hair follicle, and because, well, nobody likes the smell of burning hair. After about 10 minutes, I was sent on my way and advised to come back in another six weeks. Laser hair removal requires a strict schedule and works in conjunction with the hair cycle for optimal results. Every appointment thereafter was just as easy, and now, completely through all six of my sessions, my hair is almost completely gone, with the occasional stubble appearing here and there.

So how do you know if your skin will need one of these specialized lasers? Different ethnicitiesregardless of skin tonereact differently to lasers. Your skin may appear to be a 3 or 4 on the Fitzpatrick scale, but if youre, say, Latin or Asian, it could react to the laser as a 6 would, Dr. Chapas says. So be sure that youre only going to facilities that have operators trained in dermatology, and are skilled enough to differentiate your skin tone.

When embryonic Stem Cell therapy was first discovered in 1998, it changed the face of medicine. The idea of being able to regenerate and replace damaged cells seemed futuristic at the time, yet today such treatments are commonplace. Now, science has taken another quantum leap this time into the nano-sized world of exosomes, tiny bubbles that grow out of cell walls and contain much of the information contained within the cell including Growth factors, microRNA and messenger RNA. Mesenchymal stem cell (MSC) exosome therapy is currently one of the hottest trends in regenerative medicine, one that patients at AM Medical in Yelm can now experience.

Everyone has heard of stem cell therapy, but it turns out that its not the stem cells that are doing the work, says Dr. Ana Mihalcea, President of AM Medical. Its the exosomes that carry the information of regeneration. Infused stem cells, attach to blood vessel walls, and then give off exosomes.

Exosomes have several key differences from stem cells; they do not get removed from the circulation like stem cells, which are in the body for less than 72 hours before they get destroyed by the immune system; they do not produce a rejection reaction because they are not a cell and contain no DNA, and they pass the blood brain barrier, Mihalcea notes. In a study on stroke scientists fluorescently tagged exosomes, and the infused exosomes went exactly to the region where the stroke had occurred, she adds. The same was not true of stem cells as they do not cross the blood brain barrier.

As a result of their powerful cargo, exosomes can be used to address a multitude of conditions, including arthritis, autoimmune disorders, cardiovascular and neurogenerative diseases like Parkinsons and Alzheimers. Old cells can be reprogrammed by MSC exosomes as the target cells can transcribe the microRNA into functional proteins. Just like a virus, the exosome information of the young stem cells can infect the old cells with Youth, explains Mihalcea.

Spinal cord injuries are an area in which exosomes have produced dramatic results. Mihalcea cites the example of Dr. Douglas J. Spiels Interventional Pain Specialty Practice in NJ. Dr. Spiel has been able to rehabilitate spinal cord injuries with Exosome infusions into the spine and intravenously, she says. After several weeks, hes had patients regain muscle strength and sensation. These are prolonged, ongoing regenerative effects that continued to improve for months after the infusion.

When it comes to autoimmune diseases, inflammation plays a key role. Again, exosomes are able to reduce the problem by downregulating inflammation. TGF Beta 3 [Transforming growth factor beta-3] is the most important anti-inflammatory protein in the body and is abundant in MSC exosomes says Mihalcea. Many more Growth factors for blood vessel growth, neuronal and other tissue growth are present, allowing regenerative effects in all organ systems including skin wounds and burns.

The exosomes at AM Medical come from a laboratory in Florida that conducted pioneering research in the field. They come from perinatal mesenchymal stem cells and are scanned for any possible viruses to ensure their safety. Once harvested, the exosomes are concentrated so they can be infused in large doses.

For patients who qualify, the infusion process takes 10 to 15 minutes. Already, its been producing results for AM Medical patients. Weve had people with arthritis and chronic pain who had great responses, Mihalcea notes. There is an overall increase in wellbeing and sense of rejuvenation that is definitely noticeable.

Perhaps one of the largest sources of excitement over exosomes has to do with their anti-aging effects. Recently, ideas about the root causes of aging have been evolving, according to Mihalcea. Its been thought that aging occurs due to multiple different reasons like stem cell exhaustion, epigenetic changes, telomere shortening and others, she explains. It turns out that exosomes can modify almost all the hallmarks of aging. Theyre changing epigenetic expression to youthful function, and there are many potential applications. This is a new frontier in regenerative medicine that can help many people.

Cutting Edge Exosome Regenerative Therapy Comes to Yelm's AM Medical - ThurstonTalk

Spinal Cord Stem Cells Comments Off on Cutting Edge Exosome Regenerative Therapy Comes to Yelm’s AM Medical – ThurstonTalk | December 12th, 2019

Biomedical engineers at Duke University have developed a system that allows for real-time observations of individual cells in the colon of a living mouse.

Researchers expect the procedure to allow new investigations into the digestive systems microbiome as well as the causes of diseases such as inflammatory bowel disease and colon cancer and their treatments.

The procedure described online today (December 11, 2019) in Nature Communications involves surgically implanting a transparent window into a mouses abdominal skin above the colon. Similar setups are already being used to allow live looks into the detailed inner workings of the brain, spinal cord, liver, lungs and other organs. Imaging a live colon, however, is a slipperier proposition.

A brain doesnt move around a lot, but the colon does, which makes it difficult to get detailed images down to a single cell, said Xiling Shen, the Hawkins Family Associate Professor of Biomedical Engineering at Duke University. Weve developed a magnetic system that is strong enough to stabilize the colon in place during imaging to obtain this level of resolution, but can quickly be turned off to allow the colon to move freely.

This video shows green fluorescent colon neurons activated by neurostimulation in real-time. This is the first time that sacral nerve stimulation, an FDA approved therapy for colon motility disorders, has definitively been shown to activate neurons in the colon in live animals, explaining why the therapy might work.

Immobilizing the colon for imaging is a tricky task for traditional methods such as glue or stitches. At best they can cause inflammation that would ruin most experiments. At worst they can cause obstructions, which can quickly kill the mouse being studied.

To skirt this issue, Shen developed a magnetic device that looks much like a tiny metal nasal strip and can be safely attached to the colon. A magnetic field snaps the colon into place and keeps it stable during imaging, but once turned off, leaves the colon free to move and function as normal.

A vital organ that houses much of the digestive systems microbiome, the colon can be afflicted by diseases such as inflammatory bowel disease, functional gastrointestinal disorders, and cancer. It also plays a key role in regulating the immune system, and can communicate directly with the brain through sacral nerves.

There is a great need to better understand the colon, because it can suffer from so many diseases and plays so many roles with significant health implications, Shen said. In the study, Shen and his colleagues conducted several proof-of-principle experiments that provide starting points for future lines of research.

The researchers first colonized a living mouse colon with E. coli bacteria, derived from Crohns disease patients, that had been tagged with fluorescent proteins. The researchers then showed they could track the migration, growth and decline of the bacteria for more than three days. This ability could help researchers understand not only how antagonistic bacteria afflict the colon, Shen says, but the positive roles probiotics can play and which strains can best help people with gastrointestinal disorders.

In the next experiment, mice were bred with several types of fluorescent immune cells. The researchers then induced inflammation in the colon and carefully watched the activation of these immune cells. Shen says, this approach could be used with various types of immune cells and diseases to gain a better understanding of how the immune system responds to challenges.

Shen and his colleagues then showed that they could tag and track colon epithelial stem cells associated with colorectal cancer throughout radiation treatment. They also demonstrated that they could watch nerves throughout the colon respond to sacral nerve stimulation, an emerging therapy for treating motility and immune disorders such as functional gastrointestinal disorders and irritable bowel disorder.

While we know electrically stimulating the sacral nerves can alleviate the symptoms of these gastrointestinal disorders, we currently have no idea why or any way to optimize these treatments, Shen said. Being able to see how the colons neurons respond to different waveforms, frequencies and amplitudes of stimulation will be invaluable in making this approach a better option for more patients.

A Real-Time Window Into the Hidden World of the Colon of a Living Animal - SciTechDaily

Spinal Cord Stem Cells Comments Off on A Real-Time Window Into the Hidden World of the Colon of a Living Animal – SciTechDaily | December 12th, 2019

PATIENTS with life-changing injuries could walk again thanks to a pioneering electrical spinal implant. The device has proven effective in trials on macaque monkeys and researchers in Canada are hopeful it will be available for use on human patients in as little as a decade.

Lead researcher Dr Vivian Mushahwar, of the University of Albertas Neuroscience and Mental Health Institute, said: We think that intraspinal stimulation itself will get people to start walking longer and longer, and maybe even faster.

That in itself becomes their therapy. Theres been an explosion of knowledge in neuroscience over the last 20 years.

Were at the edge of merging the human and the machine.

The device features hair-like electrical wires that plunge deep into the spinal grey matter, sending electrical signals to trigger the networks that already know how to do the hard graft.

To work alongside the implant, the team created a map to identify which parts of the spinal cord trigger the hip, knees, ankles and toes, and the areas that put movements together.

People tend to think the brain does all the thinking, but the spinal cord has built-in intelligence, said Dr Mushahwar.

A complex chain of motor and sensory networks regulate everything from breathing to bowels, while the brain stems contribution is basically go! and faster!

Your spinal cord isnt just moving muscles, its giving you your natural gait. Being able to control standing and walking would improve bone health, improve bowel and bladder function, and reduce pressure ulcers, the researchers say.

For those with less severe spinal injuries, an implant could be therapeutic, removing the need for months of gruelling physical therapy regimes that have limited success, they add. The team are now focused on refining the hardware further by miniaturising an implantable stimulator and getting approval for human trials.

The first generation of the implants will require a patient to control walking and movement through physical means, but longer term, the implants could potentially include a direct connection to the brain, they say.

Dr Mushahwar said it has the power to transform lives.

Imagine the future, a person just thinks and commands are transmitted to the spinal cord. People stand up and walk. This is the dream, she said.

WHILE they may not be as talkative as Jungle Books King Louie, it turns out wild orangutans have some serious communication skills.

Researchers at the University of Exeter in Devon have identified 11 vocal signals and 21 physical gesture types that the apes use to communicate with one another.

The findings reveal orangutans are highly responsive to communication, reacting either before gesturing ended or in less than a second in 90 per cent of communications.

The team studied video footage of 16 orangutans consisting of seven mother-child pairs and a pair of siblings, noting a total of 1,299 communicative signals 858 vocal signals and 441 gestures.

The sounds included the kiss squeak a sharp kiss noise created while inhaling the grumph (a low sound lasting one or two seconds made on the inhale), the gorkum (a kiss squeak followed by a series of multiple grumphs) and the self-explanatory raspberry.

Gestures included beckoning, stamping, pushing out a lower lip, shaking objects and presenting a body part.

The eight identified goals or requests of their communications are acquire object, climb on me, climb on you, climb over, move away, decrease intensity, resume play and stop that.

Orangutans are the most solitary of all the apes, which is why most studies have been done on African apes, and not much is known about wild orangutan gestures, said University of Exeter scientist Dr Helen Morrogh-Bernard. We spent two years filming more than 600 hours of footage of orangutans in the Sabangau peat swamp forest in Borneo, Indonesia.

While some of our findings support what has been discovered by zoo-based studies, other aspects are new and these highlight the importance of studying communication in its natural context.

More signals are likely to be identified in the future, the researchers say.

WE MAY like to put our feet up at Christmas but for older people, even a short period of reduced physical activity could lead to significant loss of muscle mass and gains in body fat.

Just a fortnight of walking fewer than 1,500 steps a day could have a severe impact making daily tasks harder and kick-starting chronic health conditions a University of Liverpool study found.

The team measured the effect of two weeks inactivity on 47 participants, around half of whom were elderly. All lost muscle size, strength and bone mass. But the older volunteers also experienced a big drop in cardio fitness and mitochondrial function the way cells produce energy.

If the gym is hard to get to, people should be encouraged to just meet 10,000 steps, said researcher Juliette Norman. Even this can guard against reductions in muscle and bone health as well as maintaining healthy levels of body fat.

EXPERIENCING stress at a young age could help you live longer. Juvenile Caenorhabditis elegans worms that produce more oxidants and free radicals, which are associated with stress and ageing, last longer, US researchers at the University of Michigan found. Study leader Daphne Bazopoulou said early exposure may make you better able to fight stress later in life.

AGE can be predicted by protein levels in the blood. Using blood samples from more than 4,000 18- to 95-year-olds, scientists at Stanford University, California, found 373 proteins that peak and trough across a lifespan. The blood test can also show how physiological and real ages compare, which could flag those more at risk of ageing-related illnesses or reveal the ageing effect of drugs and treatments.

To brag flagrantly is, most of us realise, unbecoming, and so a favoured mitigation tactic has emerged: the humblebrag. This is a way of masking a boast, either in a feigned complaint or as fake modesty, such as its so exhausting staying in touch with all my friends or if someone told me Id pass with first-class honours, Id never have believed them. Unfortunately for humblebraggers, the tactic is too transparent to work. Last year, researchers at the University of North Carolina and Harvard Business School found humblebraggers are less liked, and perceived as less competent, because they appear insincere.

Astronomers have found magnetic field strengths near supermassive black holes can be as strong as their intense gravitational fields. These fields are able to expel material from the vicinity of the black hole to form highly energetic outflows called jets. However, this process is not acting on material that has already passed beyond the black holes event horizon, where not even light can escape. Such material would need to be accelerated to the speed of light to escape, which would require an infinite amount of energy. No magnet, however powerful, could provide this.

Lab: Electric implant could allow people with crippling injuries to walk again - Metro Newspaper UK

Spinal Cord Stem Cells Comments Off on Lab: Electric implant could allow people with crippling injuries to walk again – Metro Newspaper UK | December 12th, 2019

A campaign has been launched to fund vital research into Multiple Sclerosis in Sheffield. Catherine Scott reports.

Sheffield Hospitals Charity is appealing for support to fund a new research project being undertaken in the city that could help find a cure for Multiple Sclerosis (MS).

MS affects more than 100,000 people in the UK and is the most common cause of physical disability in young adults. It can cause pain, fatigue, problems with memory and thinking, speech and vision problems, but most noticeably, loss of mobility.

The disease occurs when the bodys immune system becomes faulty, instead of protecting against viruses and germs, the immune system attacks the nerve fibres in the brain and spinal cord.

Currently, there is no effective treatment for MS and existing treatments focus on alleviating symptoms and their impact on long term disability. But Sheffield scientists Professor Basil Sharrack and Professor John Snowden are determined to find better treatments and even a cure for MS.

One of these 100,000 people, and a patient of Professors Sharrack and Snowden, is Allison Parfitt, 50 from Sheffield who has had MS since 2008.

Allison explained the impact this had on her life: When I was diagnosed, I felt like my whole world was falling apart around me. MS controls my life. I feel exhausted all over my whole body is tired, right down to my fingertips.

Some days, every move I make is like walking through quick sand, everything is slower. My mind feels like theres a fog inside it, stopping me from concentrating or thinking clearly. My legs wont support me anymore, so I have to use crutches or a wheelchair to get around.

Im a very independent person but that is being taken away from me. I cant even go to the shops on my own anymore, I need someone with me.

The research going on here in Sheffield gives me hope. Hope that one day, Ill receive that call to say a cures been found. It would be good to know that people in the future wont have to go through what I have.

The project will be delivered by Professor Basil Sharrack, Consultant Neurologist and Professor John Snowden, Consultant Haematologist from Sheffield Teaching Hospitals.

Professor Sharrack explained how supporting his research could help future patients like Allison.

For the first time ever, weve been able to reverse disability in some patients with MS using a brand new stem cell therapy trialled right here in Sheffield and its like nothing weve seen before.

First we destroy the faulty immune system that causes MS and then we replace it with a healthy new one, grown from a patients own stem cells. In some patients it has reversed some of the disabilities associated with their MS condition, but this isnt suitable for everyone as stem cell treatment can be quite aggressive.

The pair wants to build upon the success of their stem cell work by trying to identify a biomarker a test which will allow clinicians to predict how each patients disease is likely to progress.

Professor John Snowden explained further: Once a biomarker is identified, it can be used to measure the progression of MS and predict how the disease will develop and how it will respond to treatment.

This could help us revolutionise the way in which MS patients are treated. Doctors will be able to make more informed choices about which treatment course to follow and when to start and escalate the treatment to prevent long-term disability.

We will gain a crucial understanding about how MS works, which will help provide new information that could help identify new drugs that could potentially cure MS.

For the first time, it feels like a cure for MS could be right around the corner. Thats why it is so critical that our research goes ahead.

No other hospital in the UK combines neurology and haematology in the way we do here in Sheffield we are in a unique position. We want to get started with our research as soon as possible so that people living with MS right now can benefit from the discoveries we make. By donating to Sheffield Hospitals Charitys Multiple Sclerosis Appeal you could help create a better future for people like Allison.

Sheffield Hospitals Charity is aiming to raise 200,000 to support the research project. Anyone interested in donating or fundraising to enable the MS research to be undertaken can find out more at http://www.sheffieldhospitalscharity.org.uk/msresearch

How research in Sheffield is giving hope to MS sufferers - Yorkshire Post

Spinal Cord Stem Cells Comments Off on How research in Sheffield is giving hope to MS sufferers – Yorkshire Post | December 12th, 2019

Led by researchers at Baylor College of Medicine, a study published in the journal Cell Stem Cell reveals a new mechanism that contributes to adult bone maintenance and repair and opens the possibility of developing therapeutic strategies for improving bone healing.

Adult bone repair relies on the activation of bone stem cells, which still remain poorly characterized, said corresponding author Dr. Dongsu Park, assistant professor of molecular and human genetics and of pathology and immunology at Baylor. Bone stem cells have been found both in the bone marrow inside the bone and also in the periosteum the outer layer of tissue that envelopes the bone. Previous studies have shown that these two populations of stem cells, although they share many characteristics, also have unique functions and specific regulatory mechanisms.

Of the two, periosteum stem cells are the least understood. It is known that they comprise a heterogeneous population of cells that can contribute to bone thickness, shaping and fracture repair, but scientists had not been able to distinguish between different subtypes of bone stem cells to study how their different functions are regulated.

In the current study, Park and his colleagues developed a method to identify different subpopulations of periosteum stem cells, define their contribution to bone fracture repair in live mouse models and identify specific factors that regulate their migration and proliferation under physiological conditions.

Periosteal stem cells are major contributors to bone healing

The researchers discovered specific markers for periosteum stem cells in mouse models. The markers identified a distinct subset of stem cells that contributes to life-long adult bone regeneration.

We also found that periosteum stem cells respond to mechanical injury by engaging in bone healing, Park said. They are important for healing bone fractures in the adult mice and, interestingly, their contribution to bone regeneration is higher than that of bone marrow stem cells.

In addition, the researchers found that periosteal stem cells also respond to inflammatory molecules called chemokines, which are usually produced during bone injury. In particular, they responded to chemokine CCL5.

Periosteal stem cells have receptors molecules on their cell surface that bind to CCL5, which sends a signal to the cells to migrate toward the injured bone and repair it. Deleting the CCL5 gene in mouse models resulted in marked defects in bone repair or delayed healing. When the researchers supplied CCL5 to CCL5-deficient mice, bone healing was accelerated.

The findings suggested potential therapeutic applications. For instance, in individuals with diabetes or osteoporosis in which bone healing is slow and may lead to other complications resulting from limited mobility, accelerating bone healing may reduce hospital stay and improve prognosis.

Our findings contribute to a better understanding of how adult bones heal. We think this is one of the first studies to show that bone stem cells are heterogeneous and that different subtypes have unique properties regulated by specific mechanisms, Park said. We have identified markers that enable us to tell bone stem cell subtypes apart and studied what each subtype contributes to bone health. Understanding how bone stem cell functions are regulated offers the possibility to develop novel therapeutic strategies to treat adult bone injuries.

Deacon Butch King and his wife Debbie (left) stand with their daughter Paula Draeger (center) in front of the Seed of Hope garden at UAMS Winthrop P. Rockefeller Cancer Institute in Little Rock Dec. 4. Last month, King was able to place a seed of hope token into the garden, signifying he is cancer-free, thanks to a stem cell donation from his daughter.

Deacon Butch King was given a gift in 2017. He was diagnosed with a rare disease MDS/MPN, myelodysplastic/myeloproliferative neoplasm-unclassifiable to be exact.

The hybrid disease results when bone marrow overproduces unhealthy blood cells, according to University of Arkansas for Medical Sciences in Little Rock.

The diagnosis sent the family on a harrowing journey for the next two and a half years: four changes of insurance coverage and medical facilities, 19 rounds of chemotherapy, 430 lab results, 14 bone marrow biopsies, 11.25 gallons of donated blood and the disease progressing to Acute Myeloid Leukemia.

Looking at a deadly disease as a gift takes a radical faith in God, one that King and his wife Debbie have carried with grace to his cancer-free diagnosis Nov. 4.

It was given to us as a gift. And how do we manage gifts? We care for them, we nurture them, we polish them, show them off with pride and we give thanks to God. Those are his words, our words together. We had a gift and we had to manage it, we didnt get a choice, his wife said.

King was ordained a deacon in 2012, serving at Immaculate Conception Church in North Little Rock. The couple has four children, 12 grandchildren and six great-grandchildren, with another on the way in March. After 23 years of serving in the U.S. Air Force working in secure communications, he spent 22 years with the U.S. Postal Service.

In October 2016, he had a metal stent placed in his heart and could not have any surgeries for the following six months. In November of that year, he twisted his knee at work. When he was finally ready to have knee surgery in May, his lab work was irregular. In June they learned he had developed a rare blood disorder, MDS, which later in the year progressed to MPN. It required a stem cell transplant, with only a 30 percent chance of surviving a transplant.

I was kind of stunned at first, King said. As a deacon, he had been used to visiting the sick in nursing homes and hospitals.

This is one of the stories you can say, I know how you feel because Ive been there or were praying for you and really mean it, he said.

With every roadblock of insurance not covering the procedure or a hospital turning the transplant down because he was high risk, faith prevailed.

In December 2017, their youngest daughter Paula Draeger, 38, was a perfect match for a stem cell transplant, an extremely rare result.

OK, we can do this; were going to heal him. Weve got the perfect match. If this doesnt work, nothing will. So that was just kind of the reaction, lets do it, the married mother of two said.

Debbie King said, Shes a Spina bifida baby. We were told that she would be a vegetable when she had her spinal surgery. So shes a miracle to be here; long before this ever came God had a plan.

Once Medicare kicked in, insurance would cover a transplant if a clinical trial was available. It led the family to 13 visits to University of Oklahoma Stephenson Cancer Center in Oklahoma City, though they refused the transplant.

Debbie King said they specifically chose Oklahoma City because the family had been, and still are, praying daily for Blessed Stanley Rothers intercession.

The martyr, who grew up on a farm in Okarche, Okla., was declared blessed on Sept. 23, 2017, in Oklahoma City. He was killed in 1981 while serving his people in Guatemala.

He needed a miracle. And we said God provides miracles, Debbie King said.

Before we started any treatment we would place the entire illness and what would be happening at Blessed Stanley Rothers gravesite in Oklahoma City, visiting 11 times, she said.

Whats the miracle? The miracle is the faith. And thats what Butch has said, she said.

On March 13, the Kings were told they wouldnt be continuing the trial in Oklahoma.

We were ready to just be on maintenance and enjoy the days we had, she said. On March 14, our 44th wedding anniversary we were celebrating what we thought could be our last one.

But Dr. Appalanaidu Sasapu, hematologist oncologist with the UAMS Stem Cell Transplantation and Cellular Therapy Program, never gave up on them. Because Kings disease had progressed to leukemia in April, the stem cell procedure could now be done at UAMS and covered by insurance.

Draeger said the stem cell donations, done over a weekend via a port, were simple, with no side effects aside from building her energy up in the following week.

For what youre able to give somebody, what you have to endure pales in comparison to what hes been through and what you can give him, she said.

King no longer has the blood disease and is cancer free, though he will continue at least a years worth of chemotherapy treatments.

Since his diagnosis, they attend the smaller St. Patrick Church in North Little Rock for Mass, but he cannot yet return to ministry.

We do our prayer time in the mornings and evenings, we count our blessings every night before we go to bed and we just know, what was our blessing today? Did we see somebody that we havent seen before that God put in our path? Is it a new doctor who is going to take this on? King said.

But through this whole process weve been truly blessed, had no regrets. If I had to do it over, if thats the path of my life that God wants me to take, then Ill do it.

Deacon Butch King learns to accept the 'gift' of cancer - Arkansas Catholic

Bone Marrow Stem Cells Comments Off on Deacon Butch King learns to accept the ‘gift’ of cancer – Arkansas Catholic | December 12th, 2019

Regardless of the advancements made in understanding the genetic and molecular landscapes of acute myeloid leukemia (AML) in young patients, bespoke treatment approaches are yet to be adopted. Based on the NCCN 2009 guidelines,2 AML risk stratification depends on genetic/cytogenetic abnormalities of AML cells and groups patients into favorable-risk" (FR), intermediate-risk (IR) or poor-risk (PR) categories. This will then determine the treatment pathway of whether they will receive allogeneic stem cell transplantation (allo-SCT). Currently, treatment of IR patients is less defined and often post-induction treatment with allo-SCT is adopted. Nevertheless, this approach does not appropriately take into account the heterogeneity in this group regarding the risk of disease relapse. Despite high complete remission (CR) rates in these patients, overall survival (OS) remains low due to the high rate of relapse incidence.3

Adriano Venditti et al., from the Gruppo Italiano Malattie EMatologiche dellAdulto (GIMEMA) Foundation investigated in a multicenter prospective clinical trial (NCT01452646) the benefit of risk-adapted, MRD-based therapy in young adults with AML. This study consisted of the integration of pre-treatment cytogenetics/genetics with post-treatment MRD assessment (detected using multiparametric flow cytometry [MFC]) to stratify patients to receive post-consolidation autologous stem cell transplantation (auto-SCT) or allo-SCT.1

In conclusion, the authors recognized that this study has intrinsic limitations due to scientific progression over time, such as better understanding of basic biology, new AML classification and increased MRD monitoring, which makes the historical control not wholly comparable. However, this is the first study that attempts to apply a prospective program of risk-adapted, MRD-driven treatment in patients with NCCN-IR AML, that integrates genetics and post-consolidation MRD status.

Patients that were in the NCCN-IR group demonstrated that allo-SCT can be avoided if patients are tested MRD-negative after induction therapy. In contrast, if patients are MRD-positive, allo-SCT improved OS and prolonged DFS to comparable levels as those of patients in the NCCN-FR group. Patients in the IR group, who could not be monitored for LAIP had an inferior 2-year OS of 50% when compared to the other risk groups. This suggests that, in this group, a number of patients could have benefited from an allo-SCT. Further studies that integrate baseline factors and monitor MRD are needed, as it could potentially be a promising tool to refine and customize outcome prediction in patients with AML.

AgeX Therapeutics, Inc. (NYSE American: AGE) and Lineage Cell Therapeutics, Inc. (NYSE American and TASE LCTX), announced today that the United States Patent and Trademark Office (USPTO) has issued U.S. Patent No. 10,501,723, entitled "Methods of Reprogramming Animal Somatic Cells" covering what is commonly designated "induced Pluripotent Stem (iPS) cells. The issued claims include methods to manufacture pluripotent cells capable of becoming any cell in the body. The patent has an early priority date, having been filed before the first scientific publication of Shinya Yamanaka, for which he won the Nobel Prize for Physiology or Medicine in 2012.

"This patent broadly describes multiple techniques for reprogramming cells of the body back to the all-powerful stem cell state," said Dr. Michael D. West, CEO of AgeX and first inventor on the patent. "Perhaps more significantly, it includes certain factors that address some of the difficulties currently encountered with iPS cells. It also reflects the foundational work our scientists have undertaken to apply reprogramming technology to age-reversal, specifically, induced Tissue Regeneration (iTR) which is currently a focus of AgeX product development." A video describing the significance of the patent in AgeXs product development is available on the AgeX website.

"The issuance of this patent highlights Lineages dominant position in the field of cell therapy," stated Brian M. Culley, CEO of Lineage. "Our efforts to develop new treatments rely on well-characterized and NIH-approved human cell lines. These lines are not genetically manipulated, which avoids the safety concerns associated with genetic aberrations arising from the creation of iPS cells. We believe the Lineage cell lines provide the safest option for our current clinical-stage programs, particularly in immune-privileged anatomical sites such as the eye (OpRegen for the treatment of dry AMD) and spinal cord (OPC1, for the treatment of spinal cord injury). However, the vast intellectual property estate which underlies our cell therapy platform has never been limited to these particular cell lines. As one example, this newly-issued patent provides us with proprietary methods for producing induced pluripotent stem cells, or, as it was practiced by us prior to Yamanaka, Analytical Reprogramming Technology (ART). In certain settings, an ART/iPS approach might offer important advantages, such as for an autologous treatment or when the selection of preferential attributes from a series of iPS lines is desirable. Questions as to which stem cell technology is preferred ultimately will be answered by clinical safety and efficacy and likely will be indication-specific, so we believe it is in the best interest of our shareholders to generate patented technology which enables us to pursue programs in either or both formats which we believe will ensure the highest probability of success."

Induced Pluripotent Stem Cells (iPS) are typically derived from adult skin or blood cells which have been "reprogrammed" or "induced" to retrace their developmental age and regain the potential to form all of the young cell and tissue types of the body. In 2010 inventors of the -723 patent issued today demonstrated that this reversal of developmental aging even extended to the telomere clock of cell aging. This reprogramming technology provides an alternate source of starting material for the manufacture of potentially any type of human cell needed for therapeutic purposes. Because iPSCs can be derived directly from adult tissues, they can be used to generate pluripotent cells from patients with known genetic abnormalities for drug discovery or as an alternative source of cell types for regenerative therapies.

U.S. Patent No. 10,501,723, entitled "Methods of Reprogramming Animal Somatic Cells" was assigned to Advanced Cell Technology of Marlborough, Massachusetts (now Astellas Institute for Regenerative Medicine) and licensed to Lineage and sublicensed to AgeX Therapeutics for defined fields of use. Inventors of the patent include Michael D. West, CEO of AgeX and previous CEO of Advanced Cell Technology, Karen B. Chapman, Ph.D., and Roy Geoffrey Sargent, Ph.D.

Market Insights

Blood cancer begins in the bone marrow which is the integral source of stem cells which later are differentiated in different types of blood cells in the human body. Researchers at Bristol Myers Squibb Company have stated that approximately 1.85 million new cases of blood cancer will be diagnosed by 2040 throughout the globe.

Lymphoma is the largest indication segment for blood and bone marrow cancer treatment market. It is prevalent in 2 types Hodgkin lymphoma and Non-Hodgkin lymphoma throughout the globe. The chief variables responsible for its rising prevalence worldwide are increasing prescription of immunosuppressant drugs for treating chronic infections and genetic mutations. Leukemia occurs when the DNA of immature white blood cells gets damaged due to exposure to ionizing radiation, hazardous chemicals, smoking, etc. The prevalence rate of leukemia is highly variable across different ethnic groups with men to women ratio of 1.4.

Chemotherapy is reigning the therapy segment for blood and bone marrow cancer treatment market. The key parameter hold responsible for its increasing demand is the availability of its generic version at affordable cost, drastically reducing the healthcare burden on ailing patients. Oncologists prefer to use them in combination therapy either with radiotherapy or immunotherapy to treat patients showing resistance to first-line drug therapy. Immunotherapy will be the fastest-growing segment during the forecast period owing to its promising drug pipeline for the treatment of blood cancer.

North America representing a market share of 34.6% is dominating the regional segment for blood and bone marrow cancer treatment market. The chief contributing factor for its market supremacy is a growing incidence of blood cancer. As per the research citings of the Leukemia and Lymphoma Society (CDC) figures after every 3 minutes, 1 person in the U.S. is diagnosed with blood cancer. In 2019, approximately 176,200 people in the U.S. are diagnosed with blood cancer in the United States. Europe holds a market share of 30.8% owing to the supportive regulatory framework provided by the European Medical Agency for the development and sale of medication for the treatment of blood cancer.
