Bone tissue engineering is theoretically now possible at a large scale. A*STAR researchers have developed small biodegradable and biocompatible supports that aid stem cell differentiation and multiplication as well as bone formation in living animal models.

Mesenchymal stem cells self-renew and differentiate into fat, muscle, bone, and cartilage cells, which makes them attractive for organ repair and regeneration. These stem cells can be isolated from different sources, such as the human placenta and fatty tissue. Human early mesenchymal stem cells (heMSCs), which are derived from fetal bone marrow, were thought to be best suited for bone healing, but were not readily accessible for therapeutic use.

Existing approaches to expand stem cells for industrial applications tend to use two-dimensional materials as culture media, but their production yields are too low for clinical demand. Furthermore, stem cells typically need to be harvested with enzymes and attached to a scaffold before they can be implanted.

To bring commercially viable cell therapies to market, Asha Shekaran and Steve Oh, from the A*STAR Bioprocessing Technology Institute, have created directly implantable microscopic spheres in collaboration with the A*STAR Institute of Materials Research and Engineering. These spheres, which acted as heMSC microcarriers, consist of a biodegradable and biocompatible polymer called polycaprolactone.

According to Shekaran, their initial aim was to expand stem cells on microcarriers in bioreactors to scale up production. However, this strategy threw up difficulties, especially when attempting to effectively dissociate the cells from the microcarriers and transfer them to biodegradable scaffolds for implantation.

"A biodegradable microcarrier would have a dual purpose," Shekaran says, noting that it could potentially provide a substrate for cell attachment during scalable expansion in bioreactors, and a porous scaffold for cell delivery during implantation.

The researchers generated their microcarriers by synthesizing polycaprolactone spheres and coating them with two proteins polylysine and fibronectin. These proteins are found in the extracellular matrix that assists cell adhesion, growth, proliferation, and differentiation in the body.

Microcarriers that most induced cell attachment also promoted cell differentiation into bone-like matrix more strongly than conventional two-dimensional supports. In addition, implanted stem cells grown on these microcarriers produced an equivalent amount of bone to their conventionally-derived analogs.

"This is encouraging because microcarrier-based expansion and delivery are more scalable than two-dimensional culture methods," says Shekaran.

The team now plans to further investigate the therapeutic potential of these microcarrierstem cell assemblies in actual bone healing models.

Researchers will use stem cell therapy to grow heart muscle in new study – Cardiovascular Business

By Sykes24Tracey

The U.S. Food and Drug Administration (FDA) has approved a new study that will test the efficacy of a stem cell technique used on children suffering from congenital heart disease.

The study is being hosted by Boston Childrens Hospital and Mesoblast Limited, a regenerative medicine company based in Australia. Their 24-patient trial will test the efficacy of Mesoblasts proprietary allogenic mesenchymal precursor cells (MPCs) in a corrective heart surgery on children under the age of 5 that suffer from hypoplastic left heart syndrome (HLHS), according to an April 3 press release.

The new technique is designed to save more patients with HLHS because current treatment is not always effective. Right now physicians generally perform a single, ventricle palliation, which results in the patient using only the right ventricle to the support the hearts entire circulation. However, the treatment is usually only a temporary fix because the right ventricle will eventually tire out, putting the patient at an increased risk for sudden cardiac arrest.

In the randomized, controlled trial, researchers will inject Mesoblasts MPC-150-IM into the left ventricle during surgical recruitment procedures, which should improve ventricular mass and function and ultimately lead to a higher likelihood of biventricular conversion.

The objective of combining Boston Children Hospitals expertise in pioneering surgical approaches to treating hypoplastic heart syndrome with the regenerative potential of our lead cardiovascular product, MPC-150-IM, is to develop a highly innovative treatment for this complex congenital condition as well as other serious and life-threatening cardiac diseases in children, said Kenneth Brow, the senior clinical development executive and head of cardiovascular diseases at Mesoblast, in a statement.

New technique helps researchers determine how stem cells differentiate – Phys.Org

By daniellenierenberg

April 5, 2017

Stem cell differentiation can now be seen thanks to a combination of machine learning and microfabrication techniques developed by scientists at the RIKEN Quantitative Biology Center in Japan. The results, published in PLOS One, followed the differentiation of human mesenchymal stem cells (MSC) which are easily obtained from adult bone marrow.

MSCs have proven to be important for regenerative medicine and stem cell therapy because they can potentially repair many different types of organ damage, as they have the ability to differentiate into various cell types including bone, muscle and fat. Depending on the way the cells are grown the results can be quite different and so controlling differentiation is an important goal.

Observing MSC differentiation under different conditions is an essential step in understanding how to control the process. However, this has proved challenging on two fronts. First, the physical space in which the cells are grown has a dramatic impact on the results, causing significant variation in the types of cells into which they differentiate. Studying this effect requires consistent and long lasting spatial confinement. Second, classifying the cell types which have developed through manual observation is time consuming.

Previous studies have confined cell growth with fibronectin on a glass slide. The cells can only adhere and differentiate where the fibronectin is present and are thus chemically confined. However, this procedure requires high technical skill to maintain the confinement for an extended period of time. To overcome this, the first author of the study, Nobuyuki Tanaka, decided to look for a new way to confine them. Using a simple agarose gel physical confinement system, he found that he could maintain them for up to 15 days. Tanaka says, "It was wonderful to be able to do this, because agarose gel is a commonly used material in biology laboratories and can be easily formed into a micro-cast in a PDMS silicone mold."

He continues, "The advantage of this system is that once the PDMS molds are obtained the user only needs agarose gel and a vacuum desiccator to create highly reproducible micro-casts." The vacuum pump pulls the agarose gel into the mold. He explains, "We provided the protocol to our coauthors at ETH Zurich and they performed the agarose micro-casting and conducted the stem cell differentiation study. Stem cells were captured in the micro-structures and their differentiation was controlled under the captured condition."

Tanaka's paper also describes an automated cell type classification system, using machine learning, which reduces the time and labor needed to analyze cells. "Combined together, these tools give us a powerful way to understand how stem cells differentiate in given conditions."

According to Yo Tanaka, leader of the Laboratory for Integrated Biodevice, where the research was conducted, "We hope this will break down the barriers that have hindered research in this area so far and help to establish harmony between biologists and engineers. The focus of engineers has traditionally been to develop new technologies, but scientists prefer to use well established technologies. However, if our newly developed technology is simple enough it can spread rapidly, this is our goal."

Lungs of mice found to produce blood – The Manitoban

By daniellenierenberg

Home Science & Tech

By Malak Abason April 5, 2017

Lungs are a crucial organ in many animals, including humans. While their function has always seemed pretty straightforward to take in oxygen, transfer it into blood, and exhale carbon dioxide scientists have found a previously unrecognized function of the lungs of mice: blood production.

The study, which was published in Nature by researchers at the University of California San Francisco, was performed by inserting fluorescent protein into the mouses genome.

The protein caused the platelets (small blood cells that bind together to help create blood clots when a blood vessel is damaged), in the mouse to glow, allowing scientists to trace the platalets paths. What they found was a massive number of megakaryocytes, a stem cell that produces in the lungs.

When researched further, scientists found that the lung was producing over 10 million blood-producing platelets per hour, and the platelets produced by the lung accounted for the majority of platelets in the mouses circulatory system. Researchers are theorizing that the megakaryocytes are created in the bone marrow, but then travel to the lung to produce platelets.

While it is known that human lungs produce platelets and produce blood, as small amounts of megakaryocytes have been found in lungs before, if these findings are reproduced in humans, it will prove that the sheer amount that lungs produce has been greatly underestimated.

The study also found a reservoir of stem cells with the ability to become blood cells in the lungs. Researchers implanted lungs with the fluorescent megakaryocyte cells into mice that had been engineered to have no blood stem cells in their bone marrow, and found that the fluorescent cells travelled from the lungs to the marrow, and helped to produce platelets and other ingredients in blood, including neutrophils. In cases where the bone marrow is dealing with platelet or stem cell deficiency, these stem cells were able to leave the lung and contribute to the refilling of platelets in the marrow.

If further research indicates that these findings also apply to humans which they very well may, considering the genetic and biological similarities between mice and humans it will not only disprove the current theory that states the bone marrow accounts for most of the human bodys platelet production, but it will also affect how scientists approach treating blood diseases in humans, particularly ones that result in a platelet deficiency, such as thrombocytopenia.

Stem-cell therapy is poised to disrupt the Tommy John epidemic in baseball – Quartz

By NEVAGiles23

For about half a decade, its been something of an open secret in baseball that playerspitchers especiallyregularly undergo stem-cell therapy to stave off surgeries and lost playing time. Its a cutting-edge medical procedure, done by everyone from high-school standouts to major-league all-stars. Its rarely discussed by players, or by their coaches, parents, doctors, or employers.

So when the Los Angeles Angels went public in 2016 with the news that first Andrew Heaney and then Garrett Richards were undergoing stem-cell therapy for torn ulnar collateral ligaments (UCLs), it was both anticlimactic and a revelation. For the first time, baseball pitchers and their employers were openly admitting trying this novel procedure that, while fairly well-proven anecdotally, has yet to be validated by any well-designed scientific study.

By now, that so-called Tommy John surgery for a torn or damaged UCL has become a rite of passage for the top-flight professional baseball pitcher is a cliche of sports punditry. Every young arm that can fold and then unfold itself into tortuous patterns that facilitate throwing baseballs at 95 miles per hour or faster is bound for the knife, once those upper body contortions inevitably tears the tissue on the inside of their elbows connecting their upper and lower arms, the UCL.

The first Tommy John surgery (or more properly, UCL reconstruction) was performed in 1974 by the orthopedic surgeon Frank Jobe, then the team physician for the Los Angeles Dodgers, on the eponymous pitcher. It was a great success; Tommy John came back to pitch 14 more years in the pros, racking up 164 wins with four different teams.

TJ surgery is fairly straightforward: the connective tissue that makes up the UCL is either replaced with a tendon taken from elsewhere in the patients own body or from the donated tissue of a cadaver.

Nevertheless through the mid-1970s and into the 80s, TJ was something of a rarity; just a handful of baseball players underwent that particular knife. In the 1990s the numbers started to tick up, and then in the 2000s, they exploded. From 1995 to 2005, there was an average of 28 TJ surgeries per year across all levels of pro baseball; from 2005 to 2015, there was an average of 84 TJ surgeries per year.

Then something strange happened. In 2016, the total number of TJ surgeries performed dropped to 90, from 127 the year before, a 30% decline. Only one other year in Tommy John history, 2008, saw such a precipitous drop from the previous year. By 2009, TJ numbers were back to 2007 levels; obviously it remains to be seen whether 2017 will look more like 2015 or more like last year. But the data suggest that if TJ surgery numbers are in fact starting to trend downward, it might have something to do with the rise of stem-cell therapy.

What makes stem cells unique is that they are whats called undifferentiated; they can become other specialized cells depending on the bodys need at the time. There are two types of human stem cells, embryonic and adult. Embryonic stem cells come from a very early-stage embryo; these are what you likely think of when you hear the term stem cellstheyre at the center of one of most exciting fields of medical science research today. Embryonic stem cells are now used or are being studied for a shockingly wide range of applications, from Alzheimers and autism to vision impairment and infertility. However, thanks to the religious right-driven opposition to the harvesting, study, and use of embryonic stem cells, theyve been mired in controversy in the US.

On the other hand, the use of adult stem cellswhich can be harvested from bone marrow, fat, or blood of any person of any age (the name is a bit misleading)is widely accepted by both the medical community and politicians. They have less range, so to speak, than embryonic stem cells; they are primarily to repair and replace damaged tissue in the area they are found. That makes them just about perfect for repairing a torn UCL.

The first pro baseball player known to have undergone stem-cell therapy for a UCL weakness was Bartolo Colonand he was basically forced into talking about it. Following a long run of success culminating with a Cy Young Award season in 2005, Colon had four frustrating years racked with injury and ended up unsigned after 2009. He took a year off to recuperate and in spring of 2011, he was back, signed with the New York Yankees and feeling good. Serge Kovaleski, an investigative reporter with the New York Times, started digging into how Colon had made his comeback, and uncovered the name of Joseph Purita, an orthopedic surgeon and stem-cell therapy pioneer.

As Purita tells it, there was nothing illegal or nefarious about the work hed done on Colon; there was just never a plan to broadcast it, either. Then, he recalls, the Times called me up and said were going to write a story whether or not. So, Purita offered details. In April 2010, he told the paper, a team of Dominican doctors used stem-cell therapy to help repair Colons ligament damage and torn rotator cuff.

Colons recovery was a resounding success. Hes been an all-star twice, is the current active leader in major league wins, and, at age 44, is signed to a $12.5 million contract to be the Atlanta Braves number two starter for the 2017 season.

I cant give names but there are some professionalsBut instead of thrusting stem-cell therapy into the mainstream, the Colon incident forced it to stay underground. The treatment was not well understood at that point, and the circumstancesthat it was done offshore, that it was unearthed by investigative reporting, and that, in 2012, Colon was suspended for 50 games for testing positive for testosterone useclouded public opinion on it. Many were convinced Colon had gotten performance-enhancing drugs in the Dominican Republic. Purita denies this vociferously, and MLB inquiries back him up.

The upshot is that every doctor I spoke to who studies and performs stem-cell therapy for torn-ligament repair says some version of the same thing: I cant give names but there are some professionals who have come in for treatment, says Joshua Dines, an orthopedic surgeon at New Yorks Hospital for Special Surgery, and an assistant team physician for the New York Mets.

Purita says that since Colon, hes worked with some players that had team approvaland some just come on their own, but none wanted to go public about the procedure.

If use of your arm is mostly limited to spreadsheet jockeying and lifting forkfuls of pasta or salad from plate to maw, TJ is no big dealin that case, youre ready to go back to work in six weeks. But if you throw a ball at top speed past another pro athlete for a living, youre going to be out of commission for 18 months or more as you regain strength in your money arm.

And money is the (post) operative word. In 2016 alone, MLB teams lost nearly $60 million in player value because they had to fulfill dozens of contracts of players recovering from Tommy John. Thats nearly enough to field an entire pro teamdefinitely enough to roster a top-of-league pitching staff. And that $60 million doesnt come close to accounting for the losses suffered by players who had to undergo the knife during the last year of a contract, and found themselves released by their previous teams with no new offers on the table while they recovered.

There was never going to be a way to prevent the need for Tommy John surgeries. Baseball players throw far too hard, with far more breaking pitches, starting at far too young an age, to realistically stop UCLs from tearing (though all sports medicine experts do now warn coaches and parents to keep kids and teens at low pitch counts). The alternative was always going to be something that could cure ligament tearsbut better than TJ surgery, with a faster recovery time.

Everything weve seen in the past decade or so suggests stem-cell therapy is exactly that. At this point, platelet-rich plasma (PRP) injections are common first-line defenses against UCL injuries. The procedure entails harvesting PRP from the player and injecting it into the injured part of the body. PRP is dense with proteins specialized for injury repair.

You can think of these injections as a precursor to stem-cell therapy; both are considered biologic treatments and entail wielding the bodys own weapons against injury. Many of the doctors now doing stem-cell therapy started off with PRP procedures. When baseball players have a torn ligament, they typically try PRP first. If that fails, its Tommy John time.

Everyone in the field says that at this point PRP is last decades technologyExcept, everyone in the field says that at this point PRP is last decades technology, more than ready to be replaced by stem-cell therapy, which does much the same thing but better. Adult stem cells essentially are there for the very purpose of tissue repair. Why not take them from a part of the body thats all good, and send them to a region where reinforcements are desperately needed?

Dines says that in his own practice, hes been able to cut down the need for Tommy John surgery by about a third, thanks to his reliance on stem-cell therapy. He doesnt believe that the procedure will lower the number of players that have to have TJ, but it will limit the number of overall TJ surgeriesbecause at this point, many pitchers have to get the surgery twice in their career. Dines says stem-cell therapy can get 15- or 16-year-old pitchers through their first partial tear. They may still need to get a full TJ surgery by age 24, but avoiding that first one is still a huge victory. (A growing number of middle-age first-time TJ patients could also explain the overall drop in Tommy John surgeries.)

Purita is even more optimistic. While most orthopedic surgeons say that, right now, stem-cell therapy is effective on partial, but not full, ligament tears, Purita is confident his version can handle any UCL. He sent Quartz a photo showing a patientan MLB pitcher who wishes to remain anonymous, Purita sayswho had a full UCL tear in November 2011 and, after receiving stem-cell therapy at Puritas clinic, made a full recovery by February 2013.

You never say something replaces something else entirely, Purita says. Stem-cell therapy is not going to replace every case [of Tommy John], but it could probably replace the majority of cases.

Talk to anyone who knows the field and theyll rattle off the same reasons why stem-cell therapy for UCL tears isnt already the standard of care: One reason is that, relative to the population, the number of UCL tear patients is extremely small, which means theres only a tiny pool from which to draw potential study participants. Two, a trial for a new medical treatment is typically only considered well-designed if the subjects are blindthat is, they dont know if they are getting the real treatment or a placebo. But what kind of team or player is going to risk a million-dollar arm on a properly designed study where theres a 50% chance that the injury gets a placebo?

Thats not to say that this is some sort of back-alley procedure. Its performed by some of the most prestigious orthopedic surgeons and medical research centers in the US, and the US Food and Drug Administration approves its use: US doctors are allowed to harvest a persons stem cells and use those cells to treat that same person, as long as you dont manipulate (e.g. genetically modify) the cells.

Someone making $20 million a year is not going to do something he hasnt checked out wellThe lack of literature on the procedure hasnt exactly inspired the confidence of players and teams to go public with their decision to pursue it; nor does the fact that the procedure for years had, as Dines puts it, a bad rap[it] would get lumped in with things that were illegal. There was this specter of cheating. But Dines, and others, say thats changing.

The needle is moving towards this being a valid way of treating things, says Purita. People are starting to recognize that someone making [or risking] $20 million a year is not going to do something he hasnt checked out well.

Amadeus Mason, a sports medicine and biologics expert at Emory University, compares stem-cell therapy today to Tommy John in the 1980s. It was, Okay, were going to try this and see, says Mason, who trained with orthopedic surgeon James Andrews. (Andrews is the Michael Jordan of ligament repairhes saved the arms and careers of some of the greatest pitchers in major league baseball history.) There wasnt a big fanfare going in when players started with Tommy John surgeries, Mason says, but when players came back to pitch [there] was. Same thing here.

Mason thinks stem-cell therapy hasnt quite reached the inflection point, but it is near. Here, too, he sees a comparison with Tommy John: It took a while for them to perfect the procedure so that more and more doctors could do the surgery and reproduce the results well.

Right now, Mason says, there is a relatively small handful of doctors who can do stem-cell therapy for UCL tears, but that list is growing rapidly. For example, the annual conference of the Orthobiologic Institutea professional organization for regenerative medicine researchers and practitionersstarted in 2009 with 20 or so doctors; last years event had nearly 1,000.

Some players can throw faster after they have the surgeryThe Angels didnt want to talk to me about why they decided to go public with Heaney and Richards stem-cell therapies. Perhaps thats because Heaneys, on May 2, 2016, was unsuccessful. The 25-year-old former first-round draft pick underwent Tommy John surgery in July of that year after failing to regain strength in his left arm. Hell miss the entire 2017 season, setting back a promising young career.

Richards had his stem-cell procedure just 14 days after Heaney. So far, it seems to have worked. He didnt return to pitch in 2016, but in spring training this year, he was throwing nearly 100 miles per hour. Probably the Angels best starting pitcher, Richards will take the mound on April 5, and all eyes will be on his right throwing armand on his face, to see if it is registering any pain.

If Richards stays healthy this yearand next year, and the year after thathe could become something like the 21st-century Tommy John. Every team will have a stem-cell therapy expert on its medical staff, or at least one on speed dial. Careers will be saved, and so will millions of dollars.

But wider use of stem-cell therapy also will force the MLB to confront an interesting potential side effect of the procedure. Some players can throw faster after they have the surgery, says Purita. By definition, its making the performance better. Right now, major league baseball does not include stem-cell therapy in its list of banned performance enhancers (pdf). But what happens when a baseball player, perhaps a fringe pitching prospect in the low minors, feels some elbow pain one day and gets an MRI, and is diagnosed with nothingbut decides to get stem-cell therapy anyway, since it could give him an extra four miles per hour on his fastball?

The MLB will have a decision to make: To accept potential competitive imbalances to save young arms, or to seek to preserve a level playing field (or even just the fiction of one) at the cost of some of the games best players. The question is all but inevitable.

Stem Cells Show Promise For Treating Autism – Disability Scoop

By daniellenierenberg

A small, but promising study suggests that stem cells from a childs own cord blood may offer an effective treatment for autism symptoms.

Most children on the spectrum who received an infusion from their own umbilical cord blood showed improvements in behavior, communication and socialization, among other measures, while experiencing no significant downsides from the treatment.

The findings come from a study of 25 kids with autism ages 2 to 5 published Wednesday in the journal Stem Cells Translational Medicine.

All of the children who participated in the research had their cord blood banked at birth. For the trial, the kids were given a series of behavioral and functional assessments before receiving a one-time cord blood infusion. Follow-up assessments were conducted at six and 12 months after the infusion.

Not only did the researchers find that the treatment was safe, but parent reports as well as clinical assessments indicated that more than two-thirds of the children saw improvements in autism symptoms.

Most of the behavioral gains were seen in the first six months after the infusion, the study found, but they were sustained over the following six months.

We are pleased that this study demonstrated the safety of treating children with ASD with their own cord blood, said Joanne Kurtzberg, a pediatric bone marrow transplant specialist at Duke Health who worked on the study. Were also encouraged that, while small and non-randomized, there were observed improvements in a majority of the children reported by clinicians and parents.

While the findings are encouraging, researchers said that further study involving more participants is needed before any firm conclusions can be reached about the effectiveness of cord blood infusions.

We are now hoping to replicate these preliminary results in a Phase II randomized clinical trial for which enrollment is nearly complete, Kurtzberg said.

Stem Cell Transplant Making Rapid Progress – Financial Tribune

By Dr. Matthew Watson

Around 6,000 hematopoietic stem cell transplantations are carried out annually in Iran using the patients own cells, and a far higher number are performed using cells from donors who are often close relatives of the patient, according to the Hematology-Oncology Research Center and Stem Cell Transplantation (HORCSCT) affiliated to the Tehran University of Medical Sciences. Ardeshir Qavamzadeh, head of the center, said the number of stem cell transplants is on par with developed countries. The success rate in the treatment of diseases requiring transplant is 67% at HORCSCT, ISNA quoted him as saying. Referring to the fast and progressive development of stem cell discipline in Iran, he said since 1983, when the adult leukemia specialty was initiated in the country, nearly 300 specialists have been trained in the field and there is at least one specialist in each province now. Today, one cannot find a treatment method of stem cell transplant in the worlds advanced research centers that is not available or practiced in Iran. We have reached a level where we can compete with the developed nations. HSCT Hubs There are 10 hubs for hematopoietic stem cell transplant (HSCT) in the country. Each includes medical universities from the provinces with one as the focal point. Medical universities of Zanjan, Qazvin, Alborz and Qom comprise one of the hubs with Zanjan as the center, said Mehdi Eskandari, education deputy at Zanjan University of Medical Sciences. HSCT is the transplantation of multi-potent hematopoietic stem cells, usually derived from bone marrow, peripheral blood, or umbilical cord blood. It may be autologous (when the patients own stem cells are used) or allogeneic (stem cells from a donor). It is a medical procedure in the field of hematology, most often performed for patients with certain cancers of the blood or bone marrow, such as multiple myeloma or leukemia. Since HSCT is a relatively risky procedure with many possible complications, it is reserved for patients with life-threatening diseases. However, as the survival rate following the procedure has increased, its use has expanded beyond cancer, including in autoimmune diseases, blood diseases like thalassaemia major, metabolic disorders, alcoholic liver, and even rheumatism.

First-in-Human Stem Cell Clinical Trial for Spinal Injury Expands – Newswise (press release)

By NEVAGiles23

Newswise Launched in 2014 with the initial phase I study, this first-in-human clinical trial is evaluating the safety of neural stem cell transplantation in patients with chronic spinal cord injuries. The trial is a collaboration between researchers at UC San Diego School of Medicine, the Sanford Stem Cell Clinical Center at UC San Diego Health and Neuralstem, a Maryland-based biotechnology company.

The trial has been expanded to add four more qualifying participants with chronic cervical injuries involving C5-C7 vertebrae. Due to the intensive follow-up schedule, participants should consider their geographical distance from San Diego. Living within a 500-mile radius of San Diego is recommended. The primary objective is to determine the safety and toxicity of treatment, which involves a surgical intervention with six stem cell injections and a follow-up period of 60 months. Researchers will be using a line of human stem cells approved by the FDA for human trials in patients with chronic traumatic spinal injuries. The stem cells have previously been tested for safety in patients with amyotrophic lateral sclerosis.

The ultimate goal is development of an effective treatment for paralyzing spinal cord injuries, said Joseph Ciacci, MD, principal investigator and neurosurgeon at UC San Diego Health. The immediate goal is to determine whether injecting these neural stem cells into the spines of patients with injuries is safe.

For more information on the trial or participation, contact Ciaccis research office at nksidhu@ucsd.edu or 619-471-3698.

Stem Cell Therapy Market Detailed Study Analysis and Forecast by 2025 – MilTech

By NEVAGiles23

Albany, NY (SBWIRE) 04/04/2017 Global Stem Cell Therapy Market: Overview

Also called regenerative medicine, stem cell therapy encourages the reparative response of damaged, diseased, or dysfunctional tissue via the use of stem cells and their derivatives. Replacing the practice of organ transplantations, stem cell therapies have eliminated the dependence on availability of donors. Bone marrow transplant is perhaps the most commonly employed stem cell therapy.

Osteoarthritis, cerebral palsy, heart failure, multiple sclerosis and even hearing loss could be treated using stem cell therapies. Doctors have successfully performed stem cell transplants that significantly aid patients fight cancers such as leukemia and other blood-related diseases.

Global Stem Cell Therapy Market: Key Trends

The key factors influencing the growth of the global stem cell therapy market are increasing funds in the development of new stem lines, the advent of advanced genomic procedures used in stem cell analysis, and greater emphasis on human embryonic stem cells. As the traditional organ transplantations are associated with limitations such as infection, rejection, and immunosuppression along with high reliance on organ donors, the demand for stem cell therapy is likely to soar. The growing deployment of stem cells in the treatment of wounds and damaged skin, scarring, and grafts is another prominent catalyst of the market.

On the contrary, inadequate infrastructural facilities coupled with ethical issues related to embryonic stem cells might impede the growth of the market. However, the ongoing research for the manipulation of stem cells from cord blood cells, bone marrow, and skin for the treatment of ailments including cardiovascular and diabetes will open up new doors for the advancement of the market.

Stem Cells in Drug Discovery – Technology Networks

By NEVAGiles23

Early efforts to harness the potential of stem cells for treating disease were largely focused on regeneration and the ability to repair tissues in the body through cell therapies. However, as technologies have advanced, the focus is shifting to using stem cells in drug discovery applications, such as compound screening, toxicity testing, target identification, and disease modelling. Professor Christine Mummery, from the University of Leiden tells us more and explains why stem cells are particularly suited to these applications.

Why use stem cells?

What is it that makes stem cells such an attractive option for drug discovery studies? One of the main reasons is that they make a much better model of human disease and drug reactions than animal models. As Professor Christine Mummery explains, many commonly used animal models such as mice do not accurately reflect some of the workings of cells and processes in the human body, having different immune systems and characteristics, such as heart rate, for example. This can result in problems with drugs falling down in clinical trials after showing promising results in earlier animal studies.

Using more relevant models provides not only financial savings by highlighting issues earlier in the drug discovery pipeline, but also helps efforts to reduce the number of animals used in research.

Stem cells in toxicity testing

A vital part of determining a drugs safety is assessing its cardiac toxicity. This refers to the side effects a drug can have on the functioning of the heart, such as causing arrhythmias and sudden death. As well as ensuring the safety of a drug, however, there is also a need to not unduly constrain drug development. Improvements in assay design and the implementation of the Comprehensive in Vitro Proarrhythmia Assays (CiPA) are helping to find a balance in this area.

Professor Christine Mummery tells us more about the problem of cardiotoxicity and how stem cell models and CiPA can help.

Stem cells can also play a role in testing the systemic toxicity of drugs. As Dr Glyn Stacey from NIBSC explains, pluripotent stem cell lines are increasingly being used to develop new assays that enable earlier identification of drugs that can have chronic effects on the body.

Endogenous activation of stem cells A novel and promising area of currently developing research is the ability to drive regeneration endogenously using small molecules. As Professor Angela Russell from the University of Oxford describes in the following video, we might not need to rely on using stem cells themselves, but rather small molecule therapeutics that can promote repair in damaged tissues. Circumventing the need for cells could have huge benefits for both the patient and drug developers.

What are some of the hurdles?

Stem cells certainly provide numerous opportunities to accelerate the drug discovery field, but challenges do remain.

A fundamental issue faced by all researchers in this field is ensuring the quality of the cells used. As Dr Glyn Stacey explains, a good level of quality control needs to be maintained throughout, to ensure that cells have not been contaminated or mixed up with another cell line.

Understanding signalling pathways and knowing which growth factors to add to push cells to develop into progenitor cells can also present challenges to researchers developing stem cell based screening assays. Producing sufficient numbers of relevant cell types to conduct a screen is another problem commonly faced.

The final hurdle is translation to the clinic, which relies on proving the safety of a treatment, and ensuring that it does not give rise to secondary conditions. In the case of Professor Angela Russells work, this involves taking careful steps to select compounds that act through correct pathways that wont increase the risk of cancer developing.

What does the future hold?

The roles that stem cells play in the drug discovery process are likely to continue to increase, as developments in technology enable the creation of a wider range of cells and assays. A move towards using cells with greater maturity and models that incorporate a combination of different cell types, enabling the study of interactions between cells is on the horizon. These combinations of cells will teach us a lot about drug discovery and disease, says Professor Christine Mummery.

First Ph.D. recipient – UDaily

By JoanneRUSSELL25

Eddie Marks is the pioneer in the University of Delaware Department of Medical Laboratory Sciences. Hes the first Ph.D. graduate in program history.

Having completed a professional masters degree in business/biotechnology at UD, Marks jumped at the opportunity of a fledging Ph.D. in the medical sciences program. Of course, Marks was interested in the programs core courses like statistics, immunology and physiology, but the department also granted the aspiring researcher a great deal of independence.

There is a lot of freedom to be able to choose, which is what I really liked coming in, explained Marks, who researches how adult bone narrow stem cells can treat heart attacks. I took a biology ethics course and a materials science course, which, by learning some of the engineering, really helped to further my research.

With a microbiology background, Marks was used to growing cells and working under a microscope, which eased his translation into the field. He was motivated by his adviser Arun Kumar, who also took an interdisciplinary route. Kumar took an organic chemistry background and applied it to nanomedicine. As a masters students, Marks was tapped to work on a stem cell project with Kumar. He took the preliminary data and worked on turning the stem cells into tissue types.

But research is far from Marks only talent. Elsevier Health reached out to Kumar about a book on thymosins, a protein class with diverse biological activities. Kumar and Marks had used one of these thymosin proteins specific to the heart thymosin beta-4 to turn stem cells into heart tissue. So the pair drafted a book chapter on how this protein helps heal our most vital internal organ.

We looked at [the proteins] role in development as the heart is growing, its natural effects after a heart attack, how the protein gets released and how we and other researchers use it to attempt to heal the heart after certain cardiac events, said Marks.

Earlier this month, Marks successfully defended his dissertation Adult Human Bone Marrow Mesenchymal Stem Celled Primed for the Repair of Damaged Cardiac Tissue after Myocardial Infarction. Half of the numbered chapters of the dissertation were published or are currently under review in scientific journals. Each of the six chapters of the dissertation is a paper to be published.

With his Ph.D. in hand, Marks is headed to private industry, which could mean consulting or science writing.

I want to be client-facing and help an array of companies.

Combining the time spent on the masters and Ph.D. program, Marks completed the two degrees in only five and a half years. Around the country, the typical student finishes similar programs between six and eight years time. He credits the department for the unique program design and streamlined process.

The department is very connected to the hospital [Christiana Care] and has a good reputation at the University, said Marks. The faculty knows every group from biology to engineering to the Life Science Research Facility and down to STAR Campus. There are connections everywhere. My dissertation committee had incredibly varied areas of expertise and that would not happen without Medical Laboratory Sciences.

Stem cell treatment begins for dystrophy patients from Bangladesh – Daily News & Analysis

By JoanneRUSSELL25

Three Bangladeshis suffering from a highly debilitating muscular dystrophy, who arrived in Mumbai on Sunday have begun their treatment at a Navi Mumbai spine clinic.

Abdus, Rahinul and Shorab aged 24, 14 and 8 respectively were diagnosed with this crippling disease at the time of their birth.

They arrived on Sunday evening and we started the treatment on Monday, said Avantika Patil, spokesperson NeuroGen Brain and Spine Institute in Seawoods, Navi Mumbai, who is treating them for free.

They are undergoing an autologous bone marrow derived stem cell treatment. Stem cells are taken from the bone marrow in their hip bone, treated in our lab and then injected into to the patients again. We will provide a combination of stem cell therapy and neuro-rehabilitation which will also includes yoga and speech therapy sessions, Patil explained.

While the hospital is not willing to say what kind of progress can be expected in these particular cases, they revealed that in one case, a bed-ridden patient was able to walk slowly after six years of treatment.

In January, fruit seller Tofazzal Hossain sparked a rare debate about euthanasia in conservative Bangladesh in January when he pleaded with the authorities to allow his grandson and two sons to die.

Like Local 3 News on Facebook:

April 4, 2017 - MARQUETTE - UP Health System Marquette will host a bone marrow registry drive on April 12th, 2017 on the 3rd floor of the North Entrance to the hospital.

Every four minutes, someone is diagnosed with a blood cancer in the US. For thousands of patients with leukemia or other blood diseases like sickle cell anemia, a marrow transplant is their only hope.

Joining the bone marrow registry takes roughly 10 minutes of paperwork and a cheek swab. Only 1 in 430 registry members go on to donate.

If you match with a patient in need, you will receive a phone call asking to donate. Donation is always voluntary. Surgery is not always required for bone marrow donation; almost 80% of donors donate their blood stem cells in a non-surgical procedure that is very similar to donating plasma.

Please note that UP Health System - Marquette is not affiliated with the National Marrow Donor Program or the Be The Match organization. Our presence here will be to help facilitate and educate those interested in joining the Be The Match registry.

Be The Match is operated by the National Marrow Donor Program (NMDP) which manages the largest and most diverse marrow registry in the world, working to save lives through transplant.

Three Bangladeshi patients undergo stem cell therapy in Mumbai – India Today

By NEVAGiles23

Mumbai, Apr 4 (PTI) Three Bangladeshi patients, suffering from an incurable muscular dystrophy, today underwent first stem cell therapy at a Navi Mumbai based treatment centre.

"We applied a simple therapy to the patients. We took out the stem cells from their bone marrow in the hip bone and after the required processing we injected it back into their body.

"We will wait for the results as to how they respond to such treatment. Meanwhile, physiotherapy and occupational therapy is being offered to them as well," Avantika Patil, coordinator between the patients and the treating centre told PTI.

Patil, is part of the team of NeuroGen, a brain and spine institute that keeps the track of its patients.

"We learnt about the patients through an article in an international newspaper and decided to contact them as we specialise in treating such diseases.

"I am also in contact with one Noor Khan from Bangladesh, an activist who helped the three patients to furnish documents and visa procedures," she said.

A Mumbai-based organisation specialising in such diseases, Meditourz, in collaboration with NeuroGen based in Navi Mumbai, offered to provide treatment to them.

The trio have been suffering from a rare disease Duchenne Muscular Dystrophy since their birth. This is a genetic disorder which causes progressive muscle degeneration and patients rarely live beyond 30 years of age, Patil said.

Among the three, Shorab (8 year old) is having a mild disorder and early medical intervention will definitely help in terms of less painful life. Compared to him, the disease is progressive in other two patients, she said.

Tofazzal Hossain, a fruit vendor from rural Meherpur in Bangladesh, had sought mercy killing for his sons - Abdus (24) and Rahinul (14) - and grandson Shorab from his government as he could not afford the cost of their treatment.

The Navi Mumbai based centre approached the three patients through Indian government and expressed willingness to provide treatment to the disease.

Air India also offered free round trip tickets to the six persons -- three patients and three caretakers accompanying them to Mumbai from Kolkata following an appeal from Alok Sharma, neurosurgeon at the NeuroGen.

"The three patients and the three persons accompanying them took this evenings Air India flight from Kolkata to Mumbai and will also return by an Air India flight after treatment - entirely free of any charges," Air India said in a statement. PTI ND RMT

Man Receives Reprogrammed" Stem Cells From Donor In Medical First – IFLScience

By raymumme

Last week, a patient with blurry vision in his right eye walked into a doctors office and became the first person to receive reprogrammed stem cells from a donor to treat his age-related macular degeneration.

The patient a Japanese man in his 60s is not alone, as four other patients have been approved for the procedure by Japan's health ministry. The first medical case was reported on March 28 by Nature.

In a one-hour operation by surgeon Yasuo Kurimoto, the patient received skin cells from a human donor at Kobe City Medical Center General Hospital. The donors skin cells were reverse engineered into induced pluripotent stem (iPS) cells. These cells are often seen as a game-changer in the world of regenerative medicine as they have the ability to become almost any type of cell in the body.

In this case, the iPS cells were turned into retinal cells, which were then implanted into the retina of the patient, who has age-related macular degeneration. It is hoped the procedure will stop the progression of the disease, which can lead to blindness. The transplantis not being touted as a cure for the condition, merely a prevention methodfrom further damage.

During the procedure, the surgical team injected 50 microliters of liquid containing 250,000 retinal cells into the patients eye, according to the Japan Times. The real test, however, will be the next phase of monitoring.

What sets this transplant apart is also what makes the recovery process precarious. Doctors will need to keep a careful watch on the patient, as iPS cells from a donor are not a genetic match and could cause an immune rejection.

At this point, you might remember a similar case in 2014 with a Japanese woman at the same hospital. She also received retinal cells derived from iPS cells, however hers were taken from her own skin, not a donor's.

"A key challenge in this case is to control rejection," said Riken researcher Masayo Takahashi to the Japan Times. "We need to carefully continue treatment."

In an update, the team said the Japanese woman was doing well and her vision had not declined. They decided to change track and use donor cells for this study because it holds a more viable future for such transplants.

It's hoped, if all goes well here, that researchers can create a bank of donor stem cells. Such a future would cut down on costs and reduce wait times, as cultivating ones own cells can take several months. However, there's stillmuch to be done.

After the procedure, Takahashi told a press conference that the surgery went well. They will continue to monitor the situation and provide further updates in the future.

Northern Colorado Surgeon Releases Three Year Results of Bone Marrow Stem Cell Treatment – PR Web (press release)

By Dr. Matthew Watson

This study provides the first long term evidence of the safety and feasibility of utilizing a patient's own bone marrow concentrate stem cells to treat severe low back pain

Fort Collins, Colorado (PRWEB) April 03, 2017

Retired orthopedic spine surgeon, Kenneth Pettine, M.D. is excited to release the three year results of his bone marrow stem cell treatment study. Dr. Pettine has been a pioneer in the use of bone marrow concentrate stem cell injections. He was the first surgeon to inject biologics into the human spine as part of an FDA Study in the U.S. almost seven years ago. He has the only U.S. Patent on the method of treating orthopedic and spine pathology with a patient's own stem cells.

This study provides the first long term evidence of the safety and feasibility of utilizing a patient's own bone marrow concentrate stem cells to treat severe low back pain, said Dr. Pettine. Thats terrific news for patients who up until now only had the option of undergoing expensive and invasive back fusion or artificial disc surgery.

Degenerative disc disease is a common back pain diagnosis in the United States and affects millions of patients. The symptoms of the condition can become so painful that patients may be forced to miss work and are prevented from participating in regular daily activities. Treatment is often limited to palliative care such as chiropractic, physical therapy, narcotics, injections or invasive surgical procedures to try to decrease the daily chronic low back pain. Numerous studies have shown surgery improves back pain in the average patient only 40%. Stem Cell therapy improved the average patient 70% with long term follow up.

Dr. Pettines treatment uses a patient's own bone marrow concentrate stem cells to help reduce inflammation in the spine and stimulate the creation of new tissue in the spinal disc to help reverse the effects of the disease. The office procedure is performed with I.V. sedation and usually takes 45 minutes. The study noted that patients who received higher concentrations of stem cells in their injections saw a greater improvement in their back pain.. This three year follow-up research study shows utilizing a patient's own stem cells can provide long-term back pain relief and prevented the need for invasive surgery in 77% of the patients.

If you live in the Northern Colorado area and are experiencing neck or back pain due to degenerative disc disease, you can learn more about Dr. Pettines treatment and research by visiting his website at http://www.KennethPettine.com.

About Dr. Kenneth Pettine Dr. Pettine has been the principal investigator of 18 FDA studies about stem cells and their uses and is considered a pioneer in the field. He founded The Rocky Mountain Associates in Orthopedic Medicine in 1991 to offer patients a non-fusion surgical option for their neck and back pain. He co-invented the FDA-approved Prestige cervical artificial disc and the Maverick Artificial Disc. He is currently focused on the use of Mesenchymal stem cell therapy for patients desiring to avoid orthopedic or spine surgery. You can learn more about the therapy and Dr. Pettine at his website, http://www.KennethPettine.com.

Lorena: Residents support teacher who needs bone marrow transplant – KWTX

By Dr. Matthew Watson

LORENA, Texas (KWTX) Lorena residents and others from around Central Texas turned out Monday to register as bone marrow donors in support of a first grade teacher with a rare medical condition, the only cure for which is a bone marrow transplant.

Melinda Colyer, who teaches at Lorena Primary School, was diagnosed with myelodysplastic syndrome with myelofibrosis about two weeks ago.

"It's actually a disease that causes the destruction of your stem cells in your bone marrow. They do consider it a form of cancer. The only cure that will be provided is through a bone marrow transplant, Colyer said.

She said receiving the news was tough, but she says shes a fighter.

I decided to pick myself up and was able to go forward and that's what I'm doing at this point, said Colyer.

Lorena Primary School Principal Liza Cunningham said Colyer shines with positivity despite the diagnosis.

"Ms. Colyer is one of the most upbeat people you will ever meet in your entire life. She always has a positive attitude, she has a love for kids. It's very apparent in everything she does, said Cunningham.

The drive Monday was held at Midway High Schools Distance Learning Center.

The process takes less than five minutes, and involves a mouth swab to collect DNA samples.

Prospective donors must be in good health and between the ages of 18 to 44.

Anyone interested in becoming a bone marrow donor can sign up with Scott & Whites Marrow Donor Program.

"She wants everybody to go out and be tested because even if we are not a match for her, we would be a match for somebody else. And that's really what she's been telling us about this whole event and that's very selfless of her, Cunningham said.

Stem cells could be used to create ‘endless supply of blood’ – BioNews

By NEVAGiles23

A new method of producing red blood cells outside the body on a large scale has been developed by researchers at the University of Bristol.

'We have demonstrated a feasible way to sustainably manufacture red cells for clinical use We've grown litres of it,' saidDr Jan Frayne, one of the authors of the research which waspublished in Nature Communications.

Previously the most effective technique involved taking stem cells from bone marrow, which makes blood cells in the body,and inducing them to do the same in lab conditions. This was of limited practical success because each stem cell will only make about 50,000 blood cells before dying by comparison, a few drops of blood can contain around one billion red cells.

Working with NHS Blood and Transplant, the Bristol team overcame this limitation by engineering the stem cells to make them 'immortal', using DNA. from the human papilloma virus (HPV) which causes cervical cancer. Red blood cells cannot continue to divide in the bloodstream, and as they mature they shed their nuclei and with it the virus DNA. Thus the adult cells that might in the future be given to patients, if the technique is applied in clinical trials, would not contain the any of the HPV genetic material.

'It's a brilliant approach, and they seemed to have solved several of the really important bottlenecks,' said Dr Robert Lanza, chief scientific officer at the Astellas Institute for Regenerative Medicine, who was not involved in the project.

The lab-grown blood is likely to be much more expensive than donated blood, but there may be a number of potential applications. Lab-grown blood could be used for patients with rare blood types for whom a match is difficult to find. It could also be useful in military or disaster situations where there is no time for blood typing people who are critically injured. Interest has also been expressed by researchers of malaria and other blood-borne diseases.

The first studies to assess the safety of manufactured blood are due to begin at the end of this year, although the first trial will not test this new type of blood cell. Even if safety is established, for the time being there is not currently enough capacity to produce it and industrialising the process could be costly.

'To make big huge vats of it would be outside of our ability in a research lab,' said Dr Frayne. 'We'd have to have company interest.'

A Japanese man just got another person’s stem cells transplanted in … – ScienceAlert

By Dr. Matthew Watson

In what's reported to be a world-first, last Tuesday, a Japanese man received a pioneering retinal cell transplant grown from donor stem cells instead of his own.

Doctors took skin cells from a donor bank and reprogrammed them into induced pluripotent stem (iPS) cells, which can be coaxed to grow into most cell types in the body.

For this procedure, the physicians grew the iPS cells into atype of retinal cell, and then injected them into the retina of the patient's right eye.

The test subject was a man in his 60s who has been living with age-related macular degeneration-a currently incurable eye disease that slowly leads to loss of vision.

If this news sounds somewhat familiar, it's because the same team of Japanese doctors successfully performed a similar transplant in 2014. But in that case, the iPS cells came from the patient's own skin, not from a donor.

The 2014 treatment involved culturing a patient's cells into a thin sheet of retinal pigment epithelium cells, which they transplanted directly under her retina.

One year later, their results showed that the patient's disease had not progressedas it would have without any treatment, and she continues to do well.

But a second case study after the 2014 success never went ahead - the researchers found genetic abnormalities in the iPS cells they had derived from an additional patient's skin. To avoid complications, the doctors fromRIKENand Kobe City Medical Centre General Hospital decided to halt the trial and refine their approach.

Now they are back with a potentially safer technique that uses cells from a donor bank. The patient who received the transplant last week is the first of five approved for a study by Japan's health ministry in February this year. It's important to note that so far this is a safety study - a precursor to a clinical trial.

As team leader Masayo Takahashi from RIKEN told a press conference, we will have to wait and see for several years until we know for sure whether last week's transplant was a complete success - which is the whole point of doing a safety study like this.

"A key challenge in this case is to control rejection. We need to carefully continue treatment," she said.

The patient will be closely observed for a year, and then receive check-ups for three more years. The main things for the team to look out for are rejection of the new retinal cells, and the development of potential abnormalities.

An editorial in Nature praises the team's cautious approach, emphasising that this work with iPS cells could pave a smoother path for other trials in the emerging field of stem cell medicine.

If donor cells turn out to be a viable option in iPS cell procedures, it would be huge for creating more affordable stem cell treatments that anyone can benefit from.

Instead of having to induce stem cells out of each individual patient's samples, doctors could go down the cheaper and quicker route of simply picking a suitable match from a donor bank.

Stem cell treatments such as this new procedure are an extremely promising avenue in medicine, but scientists are right to remain cautious and proceed slowly. Just last month a devastating case report broke the news that three women lost their eyesight by participating in a dodgy stem cell trial.

On the other hand, in 2015, an experimental stem cell treatment showed promise in multiple sclerosis (MS) patients, and just last year, stem cell injections were used to help stroke patients in recovery.

With all these exciting developments, we'll definitely be keeping an eye on further reports from the Japanese team.

If Young Blood Can Combat Aging, It May Be Thanks to Just One Protein – Futurism

By LizaAVILA

In Brief Studies are being done on the value of replacing older blood with younger blood via transfusions. Other researchers are studying the effects of a certain protein, osteopontin, on blood cell production. 1000 Ways To Live Forever

Society is gradually changing its classification of aging as a natural phenomenon to a disease. We have made strides in our research on preventing and potentially reversing the effects of aging.In addition to the ongoing research in molecular biology ontelomeres, there is the interesting idea of utilizing young blood to combat aging. Ironically, the legends of Dracula might be vindicated in light of new research involving young blood to rehabilitate cognitive abilities in mice, which has inspiredclinical trials that may give patients a chance at beating the Grim Reaper.

Ambrosia, a company inspired by the work done by Stanford University neuroscientistTony Wyss-Coray with parabiosis in mice, charges $8,000 per patient for its human clinical trial ofparabiosis. Although there may be 600 people whotake part in the study transfusing 1.5 liters of plasma with donors between the ages of 16 and 25, thestudy is being done without the blessing of Wyss. He believes that the study does not genuinely represent the science and that, theres just no clinical evidence, and youre basically abusing peoples trust and the public excitement around this.

While Ambrosia is operatingwithout clinical evidence to support the trials, the science behind utilizing young blood in repairing and restoring aged cellular processes is worth taking a look at.

Red and white blood cells are produced from stem cellswithin bone marrow, and as we grow older, our bodys ability to replenish the number of red and white blood cells greatly depletes. Similar to the mouse trials ran by Wyss-Coray, researcherHartmut Geigerand his team at the University of Ulm in Germany looked at the bone marrow in mice at varying ages and determined that older rodents produce very low levels of the protein osteopontin.

Rather than looking at blood transfusions for apossible solution like Wyss-Corays team, Geigers team looked the potential of stem cells to test the importance of the deficient protein.The team introduced fresh stem cells into mice that had little to no osteopontin and noticed that the stem cells aged very quickly. When older stem cells were introduced to a dish with osteopontin and anactivator protein, the stem cells began to propagate blood cells.

While companies like Ambrosia are testing blood transfusions on humans to mimic an experiment that utilized a shared circulatory system between an older mouse and a younger mouse, Geigers team notes that long-term studies must be done on their work to verify the effect of osteopontin on rejuvenating cells completely.

The team is developing a drug with the protein and its activating factor, but they do not promise a fountain of youth. They do believe that there would be benefits for the immune systems of the elderly, which may be better positioned to fight diseases that are linked with cardiovascular agingafter takingthe drug.

While all this talk about immortality is exciting, it might be a while before we can actually reap the benefits of researchers studiesin the way we hope. In the meantime, we can keep dreaming away death.
