Anika (ANIK) Grows in Orthopedic Medicines on Positive Data – Nasdaq

By NEVAGiles23

Anika Therapeutics, Inc. ANIK , a global medical technology company, specializing on integrated orthopedics medicines , has made a development with its proprietary hyaluronic acid (HA) technology. The company recently published favorable data on evaluating the usefulness of HYALOFAST, a non-woven biodegradable HA-based scaffold for treatment of cartilage lesions of the knee joint.

The study was based on 40 patients with full thickness cartilage lesions of the knee joint. 20 among them were aged above 45 and the remaining, below the figure. Per the company, all patients were implanted with HYALOFAST, soaked in bone marrow aspirate concentrate (BMAC), containing mesenchymal stem cells (MSCs) and prospectively evaluated for four years.

Data from the trial demonstrated that treatment outcomes were equally effective for both the age groups. This is more encouraging for the fact that it is difficult to treat patients above 45 years of age with traditional surgical approaches such as microfracture. Based on the findings, the company claimed that irrespective of a patient's age, HYALOFAST in combination with autologous adult mesenchymal stem cells (MSCs), can be successfully used as a treatment option for cartilage lesions.

With this breakthrough, we expect the market adoption of HYALOFAST to increase significantly, boosting Anika Therapeutics' sales performance. Notably, HYALOFAST is commercially available in more than 15 countries worldwide and has been used in more than 11,000 patients so far. Also, this trial result should advance the company's procedure of regulatory submission of HYALOFAST in the US. Under 'FastTRACK' Phase III trial, it is currently enrolling patients across the U.S. and Europe.

Demand for therapeutics-based treatment in the field of integrated orthopedics medicines and traumatic conditions, is growing in leaps and bounds these days. Per a recent report by Market Research Engine in this regard, global Orthopedic Devices Market will witness a CAGR of 5% from 2016 to 2022 and is projected to reach $47.50 billion by 2022.

Some of the big names in the orthopedic device market with promising growth potential are Stryker Corporation SYK , Smith & Nephew plc SNN and Orthofix International N.V. OFIX .

Unexpected fountain of youth found in cardiac stem cells …

By JoanneRUSSELL25

Cardiac stem cells derived from young hearts helped reverse the signs of aging when directly injected into the old hearts of elderly rats, astudypublished Monday in the European Heart Journal demonstrated.

The old rats appeared newly invigorated after receiving their injections. As hoped, the cardiac stem cells improved heart function yet also provided additional benefits. The rats fur fur, shaved for surgery, grew back more quickly than expected, and their chromosomal telomeres, which commonly shrink with age, lengthened.

The old rats receiving the cardiac stem cells also had increased stamina overall, exercising more than before the infusion.

Its extremely exciting, said Dr. Eduardo Marbn, primary investigator on the research and director of the Cedars-Sinai Heart Institute. Witnessing the systemic rejuvenating effects, he said, its kind of like an unexpected fountain of youth.

Weve been studying new forms of cell therapy for the heart for some 12 years now, Marbn said.

Some of this research has focused on cardiosphere-derived cells.

Theyre progenitor cells from the heart itself, Marbn said. Progenitor cells are generated from stem cells and share some, but not all, of the same properties. For instance, they can differentiate into more than one kind of cell like stem cells, but unlike stem cells, progenitor cells cannot divide and reproduce indefinitely.

From hisown previous research, Marbn discovered that cardiosphere-derived cells promote the healing of the heart after a condition known as heart failure with preserved ejection fraction, which affects more than 50% of all heart failure patients.

Since heart failure with preserved ejection fraction is similar to aging, Marbn decided to experiment on old rats, ones that suffered from a type of heart problem thats very typical of what we find in older human beings: The hearts stiff, and it doesnt relax right, and it causes fluid to back up some, Marbn explained.

He and his team injected cardiosphere-derived cells from newborn rats into the hearts of 22-month-old rats thats elderly for a rat. Similar old rats received a placebo injection of saline solution. Then, Marbn and his team compared both groups to young rats that were 4 months old. After a month, they compared the rats again.

Even though the cells were injected into the heart, their effects were noticeable throughout the body, Marbn said

The animals could exercise further than they could before by about 20%, and one of the most striking things, especially for me (because Im kind of losing my hair) the animals regrew their fur a lot better after theyd gotten cells compared with the placebo rats, Marbn said.

The rats that received cardiosphere-derived cells also experienced improved heart function and showed longer heart cell telomeres.

The working hypothesis is that the cells secrete exosomes, tiny vesicles that contain a lot of nucleic acids, things like RNA, that can change patterns of the way the tissue responds to injury and the way genes are expressed in the tissue, Marbn said.

It is the exosomes that act on the heart and make it better as well as mediating long-distance effects on exercise capacity and hair regrowth, he explained.

Looking to the future, Marbn said hes begun to explore delivering the cardiac stem cells intravenously in a simple infusion instead of injecting them directly into the heart, which would be a complex procedure for a human patient and seeing whether the same beneficial effects occur.

Dr. Gary Gerstenblith, a professor of medicine in the cardiology division of Johns Hopkins Medicine, said the new study is very comprehensive.

Striking benefits are demonstrated not only from a cardiac perspective but across multiple organ systems, said Gerstenblith, who did not contribute to the new research. The results suggest that stem cell therapies should be studied as an additional therapeutic option in the treatment of cardiac and other diseases common in the elderly.

Todd Herron, director of the University of Michigan Frankel Cardiovascular Centers Cardiovascular Regeneration Core Laboratory, said Marbn, with his previous work with cardiac stem cells, has led the field in this area.

The novelty of this bit of work is, they started to look at more precise molecular mechanisms to explain the phenomenon theyve seen in the past, said Herron, who played no role in the new research.

One strength of the approach here is that the researchers have taken cells from the organ that they want to rejuvenate, so that makes it likely that the cells stay there in that tissue, Herron said.

He believes that more extensive study, beginning with larger animals and including long-term followup, is needed before this technique could be used in humans.

We need to make sure theres no harm being done, Herron said, adding that extending the lifetime and improving quality of life amounts to a tradeoff between the potential risk and the potential good that can be done.

Capicor, the company that grows these special cells, is focused solely on therapies for muscular dystrophy and heart failure with ongoing clinical trials involving human patients, Marbn said.

Capicor hasnt announced any plans to do studies in aging, but the possibility exists.

After all, the cells have been proven completely safe in over 100 human patients, so it would be possible to fast-track them into the clinic, Marbn explained: I cant tell you that there are any plans to do that, but it could easily be done from a safety viewpoint.

Scientists discovered how to rejuvenate rats by injecting stem cells into their hearts – Pulse Headlines

By Dr. Matthew Watson

On Monday, a group of scientists at Cedars-Sinai Heart Institute in Los Angeles, CA, discovered througha world-first experimenta form to rejuvenate elder rats old hearts by injecting cardiac stem cells from much younger rats with healthier hearts. They hope this process might eventually become useful to humans.

The first time an experiment like this was carried out was in 2009 by the same Los Angeles-based team. Now, they also proved the possibility of reversing aging in old hearts.

Heart failure is a typical cause of death in humans. Around 48 percent of women and 46 percent of men die a year from heart attacks and other heart-related diseases. They are the first reason of death worldwide, and a leading cause of death in the United States, killing over 375,000 Americans a year. Nearly half of all African-American population suffers from heart diseases.

Researchers took stem cells from the hearts of 4-month-old rats, shaped them into cardiosphere-derived cells and injected them into the hearts of other rats of 22 monthsold, an age that makes them be considered as old. They carried out a similar process to another group of rats but injected saline instead. Scientists later compared both groups.

After receiving the stem cells injection, researchers noted a significant change in the way old rats continued to live. They turned much more active and improved their functionalities. Not just their heart rates got better and faster, but also the way they ran and breathed. Their hair started to grow faster, their chromosomal telomeres which commonly shrink with age lengthened, plus other benefits. The rodents began to progressively improve their capacity of exercise along with their stamina overall.

The animals could exercise further than they could before by about 20%, and one of the most striking things, especially for me (because Im kind of losing my hair) the animals regrew their fur a lot better after theyd gotten cells compared with the placebo rats, said Dr Eduardo Marbn, director of the Cedars-Sinai Heart Institute and lead author, who is also extremely excited for having witnessed the unexpected fountain of youth.

In 2009, his team successfully repaired the damaged heart of a man who had suffered a heart attack, using his own heart tissue.

Stem cells are a really basic type of cells that can be molded and converted into other much-specialized cells through a process called differentiation, which is basicallyshaping them into any kind of body cell.They form in embryos like embryonic stem cells -, which help in the growth process of babies, along with the millions of other different cell types they need before their birth.

One of many cells scientists generated from stem cells is called progenitor cell, which shares some of the same properties. But unlike the original cells, progenitor cells are not able to divide and reproduce indefinitely. Dr. Marbn also said they discovered cardiosphere-derived cells, which tend to promote the healing of a condition that affects more than 50 percent of patients suffering from heart failure.

Our previous lab studies and human clinical trials have shown promise in treating heart failure using cardiac stem cell infusions, said Dr Marbn. Now we find that these specialized stem cells could turn out to reverse problems associated with aging of the heart.

According to Dr. Marbn, stem cells secrete exosomes, tiny vesicles which contain a lot of nucleic acids, things like RNA, that can change patterns of the way the tissue responds to injuries, and the way genes are expressed in the tissue. They are placed into the heart, and act to transform it into a better organ, helping it at the same time to improve exercise capacity and hair regrowth, he explained.

Now, Dr. Marbn is exploring a much easier way to deliver the stem cells intravenously, instead of injecting them directly into the heart. Thus avoiding surgeries, which tend to be more complicated and expensive for the patient.

Striking benefits are demonstrated not only from a cardiac perspective but across multiple organ systems, said Dr. Gary Gerstenblith, a professor of medicine in the cardiology division of Johns Hopkins Medicine, who did not contribute to the new research. The results suggest that stem cell therapies should be studied as an additional therapeutic option in the treatment of cardiac and other diseases common in the elderly.

Now, scientistsneed to make more extensive studies before using the technique in humans.

We Just Figured out How to Activate Stem Cells to Treat Baldness – Futurism

By raymumme

In BriefResearchers from UCLA have found a way to successfully reactivate stem cells in dormant hair follicles to promote hair growth in mice. Through this research, they've developed two drugs that could help millions of people worldwide treat conditions that lead to abnormal hair growth and retention.

Researchers have already explored ways to use stem cells totreat everything from diabetes toaging, and now, ateam from UCLAthinks they could potentially offer some relief for people suffering from baldness.

During their study, which has beenpublished in Nature, the researchers noticedthat stem cells found in hair follicles undergo a different metabolic process than normal skin cells. After turning glucose into a molecule known as pyruvate, these hair follicle cells then do one of two things: send the pyruvateto the cells mitochondria to be used as energy or convert it into another metabolite known as lactate.

Based on these findings, the researchers decided to see if inactive hair follicles behaved differently depending on the path of the pyruvate.

To that end, the UCLA team compared mice that had been genetically engineered so that they wouldnt produce lactate with mice that had been engineered to produce more lactate than normal. Obstructing lactate production stopped the stem cells in the follicles from being activated, while more hair growth was observed on the animals who were producing more of the metabolite.

No one knew that increasing or decreasing the lactate would have an effect on hair follicle stem cells, co-lead on the study and professor of molecular, cell, and developmental biology William Lowry explained in a UCLA press release. Once we saw how altering lactate production in the mice influenced hair growth, it led us to look for potential drugs that could be applied to the skin and have the same effect.

Based on their study, the researchers were able to discovertwo different drugs that could potentially help humans jumpstart the stem cells in their hair follicles to increase lactate production.

The first is called RCGD423, and it works by establishing a JAK/STAT signalling pathway between the exterior of a cell and its nucleus. This puts the stems cells in an active state and contributes to lactate production, encouraging hair growth.

The other drug, UK5099, takes the opposite approach. It stops pyruvate from being converted into energy by the cells mitochondria, which leaves the molecules with no choice but to take the alternate path of creating lactate, which, in turn, promotes hair growth.

Both of the drugs have yet to be tested on humans, but hopes are high that if tests are successful, they could provide relief for the estimated 56 million people in the U.S. alonesuffering from a range of conditions that affect normal hair growth and retention, including alopecia, hormone imbalances, stress-related hair loss, and even old age.

However, as undoubtedly pleased as many of those people would be to stimulate their hair growth, the potential relevance of this research stretches far beyond hair loss. The new knowledge gained regarding stem cells, specifically their relation to the metabolism of the human body, provides a very promising basis for future study in other realms.

I think weve only just begun to understand the critical role metabolism plays in hair growth and stem cells in general, noted Aimee Flores, first author of the study and a predoctoral trainee in Lowrys lab. Im looking forward to the potential application of these new findings for hair loss and beyond.

Genome architecture guides stem cell fate, Stanford researchers find – Scope (blog)

By daniellenierenberg

When the sequence of the human genome was published in 2001 it was hailed as a great achievement. But now we know our genomes are much more (and much more mysterious) than a simple linear sequence of nucleotide letters. It coils around and over itself in ways that seem mindbogglingly complex. But recently researchers have begun to unravel this mystery and realize that dynamic changes in the genomes three-dimensional structure affect how and when important genes are expressed.

Now dermatologist Paul Khavari, MD, PhD, and graduate student Adam Rubin, former graduate student Brook Barajas, PhD, and researcher Mayra Furlan-Magaril, PhD, have used new mapping techniques to peer into the deepest recesses of tissue-specific stem cells progenitor cells that hang out in specialized tissues like muscle waiting for the call to divide and specialize. They identified two types of DNA contacts that help these cells answer a call to action. They published their resultsin Nature Genetics.

As Khavari explained to me in an email:

How the human genome rearranges itself to express genes needed for specific processes, such as stem cell differentiation, has been a mystery. This work shows that this not only involves physically changing DNA contacts, but also functionally activating contacts between pieces of DNA that were already established.It revises our understanding of the genome to a more living, breathing, moving entity that literally reconfigures itself as it changes its expression rather than a static template that is merely copied.

Specifically, Khavari and his colleagues found that the transformation from a tissue-specific stem cell into a more specialized cell (a process called differentiation) involves a two-step process: First the genomes of stem cells are prepped through a looping process that brings functional parts of the genome into close contact. Then the cells bide their time until the moment of differentiation, when proteins called transcription factors are unleashed to bind to these new DNA neighbors and stimulate the expression of genes necessary to launch the coming transformation.

As Khavari said:

This research illuminates a fundamental mechanism of genome regulation that has not been appreciated before. Specifically, a stem cell is pre-wired with established contacts to express a specific set of differentiation genes but only activates them when the dynamic loops are engaged. By analogy with a race, the runners are all at the starting line and ready to run in that particular event but only the firing of the gun sets the specific event in motion.

This pre-wiring not only allows the stem cells to respond quickly to differentiation signals, but it also locks them into a specific fate, the researchers believe. In this way, a muscle stem cell avoids any missteps that could result in it mistakenly becoming a skin or a blood cell rather than a muscle cell. Interestingly, the researchers also found clues suggesting that perturbations in this looping process are sometimes associated with the development of certain diseases, including skin cancer and psoriasis.

A Low-Calorie Diet Slows Aging – Anti Aging News

By LizaAVILA

New research reveals that a low-calorie diet rejuvenates the biological clock in a powerful manner, keeping the body younger.

Scientists have determined that a diet low in calories facilitates the energy-regulating processes. A low-calorie diet also helps to keep the body younger. These results were recently outlined in Cell. The finding is attributable to scientists at the University of California at Irvine's Center for Epigenetics and Metabolism. The team of scientists has revealed the manner in which the body's circadian rhythms alter due to the aging process. These rhythms are the body's biological clock. The circuit controlled by the clock directly connectedto aging is centered on the efficient metabolism of energy in cells.

About the Study

The group of scientists used mice for their study. These mice were tested at six months and at 18 months of age. Tissue samples were taken from their livers. This isthe organ that serves as the interface between food intake and energy distribution within the body. Energy is metabolized in cells in accordance with nuanced circadian controls.

Findings

The scientists determined the 24-hour cycle of the older mice's metabolic systems stayed the same. There were significant changes in the circadian mechanism that triggers genes on and off according to the usage of energy within cells. This means older cells process energy in an inefficient manner. The mechanism works quite well in young mice but shuts off in older mice.

A second group of older mice was provided with a diet containing 30 percent fewer calories. This intake period lasted half a year. Energy processing in the cells ended up more than unchanged. Caloric restriction functions through a rejuvenation of the biological clock. Inthe context of the study, good aging is the result of a good clock.

Collaboration for Confirmation

A companion study outlined in Cell explains the work performed by a group of researchers from the Barcelona Institute for Research in Biomedicine. These researchers collaborated with the team described above to gauge body clock functionality in stem cells from the muscle and skin of young and old mice. They determined a diet low in calories conserved the majority of rhythmic functions that occur during youth. This is the additional proof needed to show a low-calorie diet significantly contributes to the prevention of the aging process's effects. It is important to keep the stem cells' rhythm young as these cells will function to renew and preserve day-night tissue cycles.

Consuming less food seems to ward off tissue aging. As a result, stem cells do notreprogram circadian activities. Thestudies described above are important as they help explain why low-calorie diets slow aging in mice. The same results might hold true for human beings.

The Study's Importance

Prior fruit fly studies have shown diets low in calories boost longevity. However, the research described above is the first to show caloric restriction impacts circadian rhythms' impact on cell aging. These studies reveal the cell path through which the aging process is controlled. The findings serve as an introduction as to how the elements of aging can be controlled in terms of pharmacology.

What's Next?

The scientists involved in these studies are adamant it is necessary to continue examining why metabolism produces a dominant effect on stem cell aging. When the link that delays or promotes aging has been pinpointed, treatments must be developed to regulate the link.

Stem cell therapy may yield positive results for worn-out knees – Waterloo Cedar Falls Courier

By Dr. Matthew Watson

Dear Doctor: I read you can use your own stem cells to rejuvenate worn-out knees. Does this really work?

Dear Reader: Worn out is a good way to term what happens to the knee joint with prolonged use. Lets look at how this happens, starting with cartilage.

The lower portion of the knee joint (at the tibia) contains shock absorbers called menisci made of cartilage. You have one on the inner portion and another on the outer portion of each knee. The upper portion of the knee joint (at the femur) is lined with cartilage as well. All of this cartilage helps protect the bones at the joint but it doesnt heal or regenerate well due to limited blood supply. When severe, worn cartilage leads to arthritis of the knee. In knee X-rays of people older than 60, 37 percent have shown evidence of arthritis of the knees.

The intriguing thing about stem cells is they have the ability to become any type of cell the body needs. The cells used for stem cell injections in the knees are called mesenchymal stem cells, and they can differentiate into bone, fat or cartilage cells. These stem cells can come from the fat cells of your body, from your bone marrow or from the inner lining of your knee joint; theyre then replicated in the laboratory and injected into the knee joint.

In a 2014 study, 55 patients who had surgery for meniscal tears of the knees were separated into three groups, with two of the groups receiving stem cell injections. Researchers found, after six weeks, pain had decreased substantially in the two groups that received stem cell injections and the decrease was even greater at one and two years after the injection.

In a 2017 study in the British Journal of Sports Medicine, researchers analyzed six studies that used stem cells for osteoarthritis of the knees. In five of the studies, stem cells were given after surgery to the knee; in the other study, stem cells from a donor were administered without surgery. All the studies showed reduced pain and improved knee function. Further, in three of the four trials, MRIs corroborated the cartilage improvements. However, the authors noted, five of the six studies were of such poor methodology that an overall conclusion about the stem cells effectiveness could not be made.

In all these studies, the most common side effect was knee swelling and stiffness, which improved over time.

There may be benefit to stem cell injections for cartilage loss of the knees, but more data is needed, especially in those who arent having surgery of the knee. Id also like to see more data on this type of therapy as a preventive measure for younger patients before their knees are worn out.

Twins’ Bartolo Coln: ‘The older I get, the more I want to play.’ – Winona Daily News

By JoanneRUSSELL25

DETROIT Near the open doorway in the Comerica Park visitors clubhouse is a sign warning the curious to stay out of the kitchen. No media, it reads, making its point in all caps. So, its with some irony that a few feet away, Bartolo Coln agrees to a brief one-on-one with a reporter, his first since joining the Minnesota Twins.

Coln has fulfilled his media requirements when he starts, speaking with reporters through Twins interpreter Carlos Font about his performances, but thats where he prefers to leave it. Hes easy to find in the clubhouse, and will say hello and shake your hand, but he also makes it clear that its not going any further which would be fine if he hadnt become an essential part of the Twins playoff chase.

When the Twins signed Coln to a minor league deal on July 7, the primary response was laughter. This is the help the American League Centrals surprise team is getting for the stretch run, a 44-year-old with a 2-8 record and 8.14 earned-run average who had just been given his outright release by the Atlanta Braves?

Well, no ones laughing now.

I think it probably raised a few eyebrows when we brought him in, but hes been valuable, manager Paul Molitor said.

What appears to be happening is another in a string of career resurrections for the right-hander who broke in with the Cleveland Indians in 1997, won a Cy Young Award in 2005 and signed his first free-agent minor league deal with Boston in 2008. Hes no longer throwing hard, but his control remains as sharp as his competitive nature.

The older I get, the more I want to play, he said.

Over his past three starts, Coln is 2-0 with a 2.82 ERA with three walks and 11 strikeouts in 22.1 innings pitched. In his last start, he became the oldest AL pitcher to throw a complete game since Hall of Famer Nolan Ryan did it for Texas in 1992. On Tuesday, hell make the most important start of the season so far in the opener of a three-game series against the first-place Cleveland Indians at Target Field.

That explains the persistence that has kept alive a career that has seemed dead more than once. It was a whopping nine years ago that Coln first signed a minor league deal with a spring training invite, a cheap gambit by the Boston Red Sox. In four seasons from 2006-09, he went 14-21 with a 5.18 ERA with three clubs while batting elbow and shoulder problems. He missed all of 2010.

I thought I was going to be done, he said.

Coln credits 2010 stem-cell treatment fat and bone marrow was re-injected into his elbow and shoulder for saving his arm. Major League Baseball studied the treatment to see if it fell under its performance-enhancing drug policy, but it has since become a popular, if not quite trumpeted, treatment for pitchers hoping to avoid reconstructive surgery.

It has helped me to keep my arm young and keep me going, Coln said.

Coln, however, did fall afoul of MLB when he tested positive for testosterone in August 2012. He was 39, and many suspected had finally hit the end of the road. Yet, he returned the next season with Oakland and went 18-6 with a 2.65 ERA and an AL-best three shutouts.

Last season, he went 15-8 with a 3.34 ERA with the Mets, parlaying the season into a one-year, $12.5 million deal with Atlanta. The Braves are still on the hook for most of that contract, meaning the Twins are getting Coln at a bargain, prorated league minimum roughly $220,000.

He chose the Twins over the Mets after receiving a call from friend and former teammate in Anaheim, Ervin Santana.

The Mets and the Twins were the teams requesting my services, and I was weighing my options, Coln said. Ervin Santana called me and asked me to come and told me how good the organization was, how good the team was. After I started looking at it, and seeing how young their pitching was and how many young kids we had on the team, and I thought its not only an opportunity for me to pitch, but an opportunity to teach other young players how to pitch and how to be big-leaguers.

Does recovery occur after spinal cord injury? | Answers …

By NEVAGiles23

Many doctors tell patients and families that recovery does not occur after spinal cord injury. This is not true. Recovery is the rule, not the exception after spinal cord injury.

Segmental recovery. Most patients recover 1-2 segments below the injury site, even after so-called complete spinal cord injuries. For example, a person with a C4/5 injury may have deltoid function on admission and then recover biceps (C5), wrist extensors (C6), and perhaps even triceps (C7) after several months, and the associated dermatomes.

Recovery due to methylprednisolone. The second National Acute Spinal Cord Injury Study (NASCIS 2) showed that patients with complete spinal cord injuries and who did not receive the high-dose steroid methylprednisolone recovered on average 8% of motor function they had lost. If they received methylprednisolone within 8 hours after injury, they recovered on average 21% of what they had lost. In contrast, people with incomplete spinal cord injury recovered on average 59% of motor function and 75% if treated with high dose methylprednisolone.

Recovery of postural reflexes. Most people with cervical or upper thoracic spinal cord injury are initially unable to control their trunk muscles. However, most will recover better trunk control over months or even years after injury.

Walking quads and paras. Most people with incomplete spinal cord injuries, i.e. ASIA C, will recover standing or walking. Walking recovery after complete spinal cord injuries, i.e. ASIA A, are rare but can occur in 5% of the cases. In the 1980s, less than 40% of spinal cord injuries admitted to hospital were incomplete. However, in the 1990s, over 60% of spinal cord injuries are incomplete and thus the incidence of walking quads or walking paras may be higher than most people think.

Both animal and human studies indicate that as little as 10% of spinal cord tracts can support substantial function, including locomotion. People often can walk even though a tumor has damaged 90% of their spinal cord. This is due to the redundancy and plasticity of the spinal cord. Multiple spinal pathways serve similar or overlapping functions. Plasticity refers to the ability of axons to sprout and make new connections. Because transected spinal cords are rare, most people have some spinal axons crossing the injury site. This is the basis of the hope that even slight regeneration of the spinal cord will restore substantial function.

Experimental Therapies for Subacute Spinal Cord Injury

Several experimental therapies are being tested in clinical trial for spinal cord injury during the first days or weeks after injury.

Monosialic ganglioside (GM1, Sygen). In 1991, Fred Geisler and colleagues reported that GM1 injected daily for 6 weeks after injury improve locomotor recovery 37 patients. Fidia Pharmaceutical subsequently tested this therapy in a large multicenter clinical trial in 800 patients, showing that the GM1 accelerated recovery during the first six weeks but did not significantly improve the extent of recovery at 6-12 months after injury. Note that this trial is no longer active. Although the drug is still available in Europe and South America, the company Fidia has been bought by another company. CareCure Forum (GM1) Link

Activated macrophage transplants. In 1998, Michal Schwartz at the Weizmann Institute reported that activated macrophages obtained from blood and transplanted to the spinal cord improve functional recovery in rats. The company Proneuron initiated phase 1 clinical trials to assess feasibility and safety of macrophage transplants in human spinal cord injury. Preliminary reports suggest that the treatment is feasible and safe. All the patients had complete thoracic spinal cord injury and received macrophage transplants within 2 weeks after injury. Three of the 8 patients recovered from ASIA A to ASIA C, more than the expected 5%. A phase 1 clinical trial is continuing at Erasmus Hospital in Brussels, Belgium. A phase 2 trial is being planned in two U.S. centers including Craig Hospital in Denver (CO) and Mt. Sinai in New York City (NY). CareCure Forum (Macrophage) Link

Alternating Current Electrical Stimulation. In 1999, Richard Borgens and colleagues at Purdue University reported that alternating currents applied to dog spinal cords stimulated regeneration and recovery of function in dogs with spinal cord injury. A clinical trial has commenced at Purdue University for people who are within 2 weeks after acute spinal cord injury. CareCure Forum (AC Stim) Link

AIT-082 (Neotrofin). This is a guanosine analog that can be taken orally and reportedly increases neurotrophins or neural growth factors in the brain and spinal cord. Neotherapeutics tested this drug in patients with Alzheimers disease. They started a multicenter clinical trial at Ranchos Los Amigos in Downey (CA), Gaylord Hospital in Wallingford (CT), and Thomas Jefferson Hospital in Philadelphia. The treatment must be started within 2 weeks after spinal cord injury. CareCure Forum (AIT-082) Link

Experimental Therapies for Chronic Spinal Cord Injury

Several therapies are being tested in clinical trials for chronic spinal cord injury, i.e. people whose neurological recovery has stabilized one or more years after injury. Many other treatments are being considered for clinical trial (see article on Advances in Spinal Cord Injury Therapy 25 November 2002).

4-aminopyridine (4-AP). This drug is a small molecule that blocks fast voltage sensitive potassium channel blockers. The drug can be obtained by physician prescription from compounding pharmacies in the United States. In addition, Acorda Therapeutics is carrying out a multicenter phase 3 clinical trial of a sustained release formulation of the drug in people who are more than one and a half years after incomplete spinal cord injury. The drug may improve conduction of demyelinated axons in the spinal cord and preliminary clinical trial results suggest that the drug may reduce spasticity and improve motor or sensory function in as many as a third of people with chronic spinal cord injury. See CareCure Forum (4-AP) Link

Fetal porcine stem cell transplants. Embryonic stem cells have attracted much attention. Several studies of human fetal cell transplants have been carried out in Sweden, Russia, and the United States, showing that transplanted fetal cells will engraft in human spinal cords. However, due in part of the lack of availability of adult human stem cells for transplantation and politics associated with the use of embryonic human stem cells, the first and only stem cell therapy trial for spinal cord injury in the United States used fetal stem cells from pigs. A phase 1 clinical trial at Washington University in St. Louis (MO) and Albany Medical Center in Albany (NY) has transplanted fetal stem obtained from pig fetuses and treated with antibodies to reduce the immune rejection. Sponsored by Diacrin, this trial is aiming to test 10 patients. See CareCure Forum (Diacrin) Link

Olfactory ensheathing glial transplants. Olfactory ensheathing glia (OEG) reside in the olfactory nerve and the olfactory bulb. They are believed to be why the olfactory nerve continuously regenerates in adults. OEG cells are made in the nasal mucosa and migrate up the nerve to the olfactory bulb. Several laboratories have shown that OEG transplants facilitate regeneration of the spinal cord. Three clinical trials have started in Lisbon (Portugal), Brisbane (Australia), and Beijing (China). In Lisbon, they are transplanting nasal mucosa obtained from the patient into the spinal cord. In Brisbane, they are culturing OEG cells from nasal mucosa and transplanting the cells to the spinal cord. In Beijing, they are culturing OEG from human fetal olfactory bulbs and transplanting into the spinal cord. See CareCure Forum Link (Brisbane) and CareCure Forum Link (Beijing)

Summary

Spinal cord injury is devastating, not only for the injured person but for families and friends. While much information is available on Internet, most of the material is scattered and out of date. This article summarizes answers to some of the most frequently asked questions by people who are encountering spinal cord injury for the first time. Spinal cord injury disconnects the brain from the body. This leads not only to loss of sensation and motor control below the injury site but may be associated with abnormal activities of the spinal cord both above and below the injury site, resulting in spasticity, neuropathic pain, and autonomic dysreflexia. Many functions of our body that we take for granted, such as going to the bathroom, sexual function, blood pressure and heart rate, digestion, temperature control and sweating, and other autonomic functions may not only be lost but may be abnormally active. Finally, contrary to popular notions about spinal cord injury, recovery is the rule and not the exception in spinal cord injury. The recovery takes a long time and may be slowed down or blocked by the muscle atrophy and learned non-use. Finally, there is hope. Many therapies have been shown to regenerate and remyelinate the spinal cord. Some of these are now in clinical trials and many more should be in clinical trial soon.

Asterias Announces Major AST-VAC2 Development Milestone: First … – GlobeNewswire (press release)

By NEVAGiles23

FREMONT, Calif., Aug. 14, 2017 (GLOBE NEWSWIRE) -- Asterias Biotherapeutics, Inc. (NYSE MKT:AST), a biotechnology company pioneering the field of regenerative medicine, today announced that Cancer Research UK, supported by Asterias technical personnel, has successfully completed manufacture of the first cGMP (current Good Manufacturing Practice) clinical grade lot of AST-VAC2, which meets all specifications for release. This lot will provide clinical trial material for patients enrolling in the first clinical study evaluating AST-VAC2 in non-small cell lung cancer.

The successful production of this first cGMP lot of AST-VAC2 is a major step towards initiating the upcoming study in non-small cell lung cancer, said Mike Mulroy, President and Chief Executive Officer. With its potential as a ready-to-use, off-the-shelf cancer immunotherapy, AST-VAC2 represents an exciting opportunity for Asterias in the rapidly evolving cancer immunotherapy sector.

Investigational therapies intended for human clinical applications must be manufactured in accordance with cGMP standards designed to help assure the safety and potency of drug products. To achieve cGMP standards, a product must be manufactured and released according to rigorous systems designed to ensure appropriate control of manufacturing facilities, equipment, raw materials, processes and testing procedures. Under the companys agreement with Cancer Research UK, Asterias has transferred its innovative laboratory scale AST-VAC2 manufacturing process to Cancer Research UKs Biotherapeutics Development Unit, which has developed and optimized the process for cGMP manufacture and is responsible for producing cGMP AST-VAC2 for use in the upcoming clinical study in non-small cell lung cancer.

About AST-VAC2

AST-VAC2 is an innovative immunotherapy product that contains mature dendritic cells derived from pluripotent stem cells. These non-patient specific (allogeneic) AST-VAC2 cells are engineered to express a modified form of telomerase, a protein widely expressed in tumor cells, but rarely found in normal cells. The modified form of telomerase permits enhanced stimulation of immune responses to the protein. The AST-VAC2 dendritic cells instruct the immune system to generate responses against telomerase which will target tumor cells. AST-VAC2 is based on a specific mode of action that is complementary and potentially synergistic to other immune therapies.

About Non-Small Cell Lung Cancer

Lung cancer (both small cell and non-small cell) is the leading cause of cancer-related death, accounting for about one-quarter of all cancer deaths and more than colorectal, breast, and prostate cancers combined. Non-small cell lung cancer (NSCLC) accounts for about 80% to 85% of lung cancers, according to the American Cancer Society. The three main types of NSCLC are adenocarcinoma, squamous cell carcinoma, and large cell carcinoma. The American Cancer Societys estimates for lung cancer in the United States for 2017 are: about 222,500 new cases of lung cancer, and about 155,870 deaths from lung cancer. Despite the large number of people afflicted by non-small cell lung cancer, patients remain vastly underserved due to a scarcity of effective treatments. According to statistics published by Cancer Research UK, the five year survival rate for lung cancer patients in England and Wales is less than 10%.

Which research results in mice will help humans with MS? Now there’s a way to tell – UB News Center

By daniellenierenberg

BUFFALO, N.Y. People with multiple sclerosis (MS) knowall too well the frustration of hearing that success in treatingthe disease in mice had little or no effect in humans.

Unfortunately, with no large animal models for MS, results thatsuggest promising new treatments in mice often are ineffective inhumans.

Now, University at Buffalo researchers have developed andsuccessfully tested a method for determining how relevant to thehuman disease findings are from mouse models. The researchwas published Aug. 8 in Stem Cell Reports.

This is an important resource for the field as it allowsus to compare human and rodent cells, and provides a point ofreference to understand whether or not gene expression patterns areconserved between species, said Fraser Sim, PhD, seniorauthor and associate professor in the Department of Pharmacologyand Toxicology in the Jacobs School of Medicine and BiomedicalSciences at UB. Co-first authors are Suyog U. Pol PhD, now apostdoctoral fellow, and Jessie J. Polanco, a doctoral candidate,both in the medical school.

MS trial failures

There have been so many failures in clinical trials forMS when promising observations are translated from small animalmodels to the clinic, Sim said. Our primarymotivation was to try to understand, at a molecular level, how thehuman cells responsible for synthesizing myelin differ from theirmuch-better-studied mouse counterparts.

MS and some other neurological diseases occur when there isdamage to myelin the fatty sheath that allows nerve cellsto communicate. So the myelin-producing cells, called humanoligodendrocyte progenitor cells, or OPCs, found in the brain andspinal cord have been a major focus of efforts to better understandMS and develop potential new treatments for it.

Sim explained that undifferentiated OPCs are frequently found inthe brain lesions of MS patients, so boosting the differentiationof these cells could lead to myelination and a reduction ofsymptoms.

From OPCs to oligodendrocytes

One reason why so many clinical trials fail may be because offundamental differences in the types and levels of genes expressedbetween mice and humans. Sim and his colleagues addressed thisquestion by performing gene-expression analysis on differentiatinghuman OPCs.

In this paper, we describe the transcriptional eventsthat underlie how human OPCs develop into oligodendrocytes,said Sim.

To do it, they used a network analysis software tool calledweighted gene coexpression network analysis (WCGNA). The softwareclusters together genes with similar patterns of expression. Italso allows for analysis of both conserved and divergent geneexpression between humans and rodents.

WCGNA looks at the relationships between genes ratherthan absolute differences between conditions in any givenexperiment, Sim said.

He added that the information encoded in levels of geneexpression increasing or decreasing is very reliable andreproducible.

We performed WCGNA in exactly the same manner on cellsisolated from mice, rats and humans, and prepared these cells in asclose to matched conditions as possible, trying to keep things assimilar as possible to facilitate this comparison, saidSim.

It turned out several of the genes the team had identified asrelevant to human disease also are involved in mouse developmentand mouse models of myelin disease.

New myelin-repairing gene

Based on its findings from that analysis, the team had predictedthat GNB4, a protein involved in signal transduction, would beinvolved in the development of OPCs in humans. The researchersfound that over-production of GNB4, a protein involved in thetransduction of extracellular signals, could cause human OPCs torapidly undergo myelination when transplanted into a model forhuman cell therapy in MS.

So this proteins expression in oligodendrocyteprogenitor cells might ultimately become a therapeutic target,potentially promoting oligodendrocyte formation in MSpatients, said Sim.

The approach also identified several other important candidatesthat play key roles in regulating the development of humanoligodendrocytes.

Other co-authors on the paper are Melanie A. OBara,research scientist; Hani J. Shayya, a UB undergraduate and Karen C.Dietz, PhD, research assistant professor, all of the Department ofPharmacology and Toxicology and Richard A. Seidman, amasters candidate in neuroscience.

The research was funded by the National Multiple SclerosisSoociety, the Kalec Multiple Sclerosis Foundation, the SkarlowMemorial Trust and the Empire State Stem Cell Fund (NYSTEM) throughthe New York State Department of Health.

UCLA Scientists Identify a New Way to Activate Stem Cells to Make Hair Grow – Newswise (press release)

By LizaAVILA

Mirabai Vogt-James

Newswise UCLA researchers have discovered a new way to activate the stem cells in the hair follicle to make hair grow. The research, led by scientists Heather Christofk and William Lowry, may lead to new drugs that could promote hair growth for people with baldness or alopecia, which is hair loss associated with such factors as hormonal imbalance, stress, aging or chemotherapy treatment.

The researchwas publishedin the journal Nature Cell Biology.

Hair follicle stem cells are long-lived cells in the hair follicle; they are present in the skin and produce hair throughout a persons lifetime. They are quiescent, meaning they are normally inactive, but they quickly activate during a new hair cycle, which is when new hair growth occurs. The quiescence of hair follicle stem cells is regulated by many factors. In certain cases they fail to activate, which is what causes hair loss.

In this study, Christofk and Lowry, ofEli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA, found that hair follicle stem cell metabolism is different from other cells of the skin. Cellular metabolism involves the breakdown of the nutrients needed for cells to divide, make energy and respond to their environment. The process of metabolism uses enzymes that alter these nutrients to produce metabolites. As hair follicle stem cells consume the nutrient glucose a form of sugar from the bloodstream, they process the glucose to eventually produce a metabolite called pyruvate. The cells then can either send pyruvate to their mitochondria the part of the cell that creates energy or can convert pyruvate into another metabolite called lactate.

Our observations about hair follicle stem cell metabolism prompted us to examine whether genetically diminishing the entry of pyruvate into the mitochondria would force hair follicle stem cells to make more lactate, and if that would activate the cells and grow hair more quickly, said Christofk, an associate professor of biological chemistry and molecular and medical pharmacology.

The research team first blocked the production of lactate genetically in mice and showed that this prevented hair follicle stem cell activation. Conversely, in collaboration with the Rutter lab at University of Utah, they increased lactate production genetically in the mice and this accelerated hair follicle stem cell activation, increasing the hair cycle.

Before this, no one knew that increasing or decreasing the lactate would have an effect on hair follicle stem cells, said Lowry, a professor of molecular, cell and developmental biology. Once we saw how altering lactate production in the mice influenced hair growth, it led us to look for potential drugs that could be applied to the skin and have the same effect.

The team identified two drugs that, when applied to the skin of mice, influenced hair follicle stem cells in distinct ways to promote lactate production. The first drug, called RCGD423, activates a cellular signaling pathway called JAK-Stat, which transmits information from outside the cell to the nucleus of the cell. The research showed that JAK-Stat activation leads to the increased production of lactate and this in turn drives hair follicle stem cell activation and quicker hair growth. The other drug, called UK5099, blocks pyruvate from entering the mitochondria, which forces the production of lactate in the hair follicle stem cells and accelerates hair growth in mice.

Through this study, we gained a lot of interesting insight into new ways to activate stem cells, said Aimee Flores, a predoctoral trainee in Lowrys lab and first author of the study. The idea of using drugs to stimulate hair growth through hair follicle stem cells is very promising given how many millions of people, both men and women, deal with hair loss. I think weve only just begun to understand the critical role metabolism plays in hair growth and stem cells in general; Im looking forward to the potential application of these new findings for hair loss and beyond.

The use of RCGD423 to promote hair growth is covered by a provisional patent application filed by the UCLA Technology Development Group on behalf of UC Regents. The use of UK5099 to promote hair growth is covered by a separate provisional patent filed by the UCLA Technology Development Group on behalf of UC Regents, with Lowry and Christofk as inventors.

The experimental drugs described above were used in preclinical tests only and have not been tested in humans or approved by the Food and Drug Administration as safe and effective for use in humans.

The research was supported by the California Institute for Regenerative Medicine training grant, a New Idea Award from the Leukemia Lymphoma Society, the National Cancer Institute (R25T CA098010), the National Institute of General Medical Sciences (R01-GM081686 and R01-GM0866465), the National Institutes of Health (RO1GM094232), an American Cancer Society Research Scholar Grant (RSG-16-111-01-MPC), the National Institute of Arthritis and Musculoskeletal and Skin Diseases (5R01AR57409), a Rose Hills Foundation Research Award and the Gaba Fund; the Rose Hills award and the Gaba Fund are administered through the UCLA Broad Stem Cell Research Center.

Further research on the use of UK5099 is being funded by the UCLA Technology Development Group through funds fromCalifornia State Assembly Bill 2664.

Cardiac stem cells rejuvenate rats’ aging hearts, study says – CNN – CNN

By Sykes24Tracey

The old rats appeared newly invigorated after receiving their injections. As hoped, the cardiac stem cells improved heart function yet also provided additional benefits. The rats' fur fur, shaved for surgery, grew back more quickly than expected, and their chromosomal telomeres, which commonly shrink with age, lengthened.

The old rats receiving the cardiac stem cells also had increased stamina overall, exercising more than before the infusion.

"It's extremely exciting," said Dr. Eduardo Marbn, primary investigator on the research and director of the Cedars-Sinai Heart Institute. Witnessing "the systemic rejuvenating effects," he said, "it's kind of like an unexpected fountain of youth."

"We've been studying new forms of cell therapy for the heart for some 12 years now," Marbn said.

Some of this research has focused on cardiosphere-derived cells.

"They're progenitor cells from the heart itself," Marbn said. Progenitor cells are generated from stem cells and share some, but not all, of the same properties. For instance, they can differentiate into more than one kind of cell like stem cells, but unlike stem cells, progenitor cells cannot divide and reproduce indefinitely.

Since heart failure with preserved ejection fraction is similar to aging, Marbn decided to experiment on old rats, ones that suffered from a type of heart problem "that's very typical of what we find in older human beings: The heart's stiff, and it doesn't relax right, and it causes fluid to back up some," Marbn explained.

He and his team injected cardiosphere-derived cells from newborn rats into the hearts of 22-month-old rats -- that's elderly for a rat. Similar old rats received a placebo injection of saline solution. Then, Marbn and his team compared both groups to young rats that were 4 months old. After a month, they compared the rats again.

Even though the cells were injected into the heart, their effects were noticeable throughout the body, Marbn said

"The animals could exercise further than they could before by about 20%, and one of the most striking things, especially for me (because I'm kind of losing my hair) the animals ... regrew their fur a lot better after they'd gotten cells" compared with the placebo rats, Marbn said.

The rats that received cardiosphere-derived cells also experienced improved heart function and showed longer heart cell telomeres.

Why did it work?

The working hypothesis is that the cells secrete exosomes, tiny vesicles that "contain a lot of nucleic acids, things like RNA, that can change patterns of the way the tissue responds to injury and the way genes are expressed in the tissue," Marbn said.

It is the exosomes that act on the heart and make it better as well as mediating long-distance effects on exercise capacity and hair regrowth, he explained.

Looking to the future, Marbn said he's begun to explore delivering the cardiac stem cells intravenously in a simple infusion -- instead of injecting them directly into the heart, which would be a complex procedure for a human patient -- and seeing whether the same beneficial effects occur.

Dr. Gary Gerstenblith, a professor of medicine in the cardiology division of Johns Hopkins Medicine, said the new study is "very comprehensive."

"Striking benefits are demonstrated not only from a cardiac perspective but across multiple organ systems," said Gerstenblith, who did not contribute to the new research. "The results suggest that stem cell therapies should be studied as an additional therapeutic option in the treatment of cardiac and other diseases common in the elderly."

Todd Herron, director of the University of Michigan Frankel Cardiovascular Center's Cardiovascular Regeneration Core Laboratory, said Marbn, with his previous work with cardiac stem cells, has "led the field in this area."

"The novelty of this bit of work is, they started to look at more precise molecular mechanisms to explain the phenomenon they've seen in the past," said Herron, who played no role in the new research.

One strength of the approach here is that the researchers have taken cells "from the organ that they want to rejuvenate, so that makes it likely that the cells stay there in that tissue," Herron said.

He believes that more extensive study, beginning with larger animals and including long-term followup, is needed before this technique could be used in humans.

"We need to make sure there's no harm being done," Herron said, adding that extending the lifetime and improving quality of life amounts to "a tradeoff between the potential risk and the potential good that can be done."

Capicor hasn't announced any plans to do studies in aging, but the possibility exists.

After all, the cells have been proven "completely safe" in "over 100 human patients," so it would be possible to fast-track them into the clinic, Marbn explained: "I can't tell you that there are any plans to do that, but it could easily be done from a safety viewpoint."

Mr. Singh continued, "In conjunction with our focused efforts to advance our AV-101 Phase 2 development program, we have continued to expand our intellectual property portfolio. Earlier this year the European Patent Office issued a Notice of Intention to Grant our European Patent Application regarding AV-101 for treatment of depression and reduction of dyskinesias associated with levodopa therapy for Parkinson's disease, a patent that will be in effect until at least January 2034. In addition, the U.S. Patent and Trademark Office recently allowed another important U.S. patent relating to stem cell technology held by VistaStem Therapeutics, our subsidiary using stem cell technology for drug rescue and regenerative medicine. The breakthrough technology under the allowed U.S. patent involves the stem cells from which all blood cells and most bone marrow cells are derived, technology with the potential to reach patients with a broad range of life-threatening diseases, including cancer, with CAR-T cell applications and foundational technology we believe may ultimately provide approaches for producing bone marrow stem cells for bone marrow transfusions. We are confident in our path forward through strategic collaborations, such as our agreement with the U.S. National Institute of Mental Health covering its full financial sponsorship of the ongoing Phase 2 study of AV-101 for MDD that Dr. Carlos Zarate Jr. and his team are conducting at the NIH's clinic in Bethesda, as well as our sublicense arrangement with BlueRock Therapeutics, a company established by Bayer AG and Versant Ventures, focused on regenerative medicine for heart disease. As we have historically, we believe we have surrounded ourselves with partners, supportive stockholders and corporate development and finance experts who share our confidence in our future and will assist us in securing key collaborations and raising sufficient capital to achieve our objectives, most notably the launch and completion in 2018 of our Phase 2 adjunctive treatment study of AV-101 for MDD. We look forward to creating value for our stakeholders in fiscal 2018 and beyond."

Potential Near-Term Milestones:

During the second half of 2017, the Company is pursuing the following objectives:

Further, the Company anticipates that the U.S. National Institute of Mental Health (NIMH) will complete the NIH-sponsored Phase 2 study of AV-101 in depression, with topline results during the first half of 2018.

Recent Operational Highlights:

Advancement of AV-101 as a Potential, Non-Opioid Treatment Alternative for Chronic Pain

Bolstered Clinical Team with Industry Expert

Intellectual Property Accomplishments

Capital Market Highlights

Financial Results for the Fiscal Quarter Ended June 30, 2017:

At June 30, 2017, the Company had a cash and cash equivalents balance of $1.6 million, compared to $2.9 million as of March 31, 2017. Between late-March 2017 and late-June 2017, in self-placed private placement transactions, the Company sold units consisting of unregistered common stock and common stock warrants to accredited investors, yielding approximately $1 million in net cash proceeds.

Net loss for the fiscal quarters ended June 30, 2017 and 2016 was approximately $2.3 million and $2.0 million, respectively, including non-cash expenses of approximately $0.5 million in each period.

Research and development expense totaled $1.1 million for the fiscal quarter ended June 30, 2017, compared with $0.8 million for the fiscal quarter ended June 30, 2016. The increase in year-over-year research and development expense was attributable to the Company's increased focus on the continuing non-clinical and clinical development of AV-101 and ongoing preparations to launch its AV-101 Phase 2 Adjunctive Treatment Study.

General and administrative expense increased slightly to $1.2 million in the fiscal quarter ended June 30, 2017, from $1.1 million in the fiscal quarter ended June 30, 2016 primarily because of increased headcount and employee-related expenses and non-cash stock compensation expense attributable to recent stock option grants, partially offset by a reduction in professional services fees.

About VistaGen

VistaGen Therapeutics, Inc. (NASDAQ: VTGN), is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other CNS disorders. VistaGen's lead CNS product candidate, AV-101, is in Phase 2 development, initially as a new generation oral antidepressant prodrug candidate for MDD. AV-101's mechanism of action is fundamentally differentiated from all FDA-approved antidepressants and atypical antipsychotics used adjunctively to treat MDD, with potential to drive a paradigm shift towards a new generation of safer and faster-acting antidepressants. AV-101 is currently being evaluated by the U.S. NIMH in a Phase 2 monotherapy study in MDD being fully funded by the NIMH and conducted by Dr. Carlos Zarate Jr., Chief, Section on the Neurobiology and Treatment of Mood Disorders and Chief of Experimental Therapeutics and Pathophysiology Branch at the NIMH. VistaGen is preparing to launch a 180-patient Phase 2 study of AV-101 as an adjunctive treatment for MDD patients with inadequate response to standard, FDA-approved antidepressants. Dr. Maurizio Fava of Harvard Medical School will be the Principal Investigator of the Company's Phase 2 adjunctive treatment study. AV-101 may also have the potential to treat multiple CNS disorders and neurodegenerative diseases in addition to MDD, including neuropathic pain, epilepsy, Huntington's disease, L-Dopa-induced dyskinesia associated with Parkinson's disease and other disorders where modulation of the NMDA receptors, activation of AMPA pathways and/or key active metabolites of AV-101 may achieve therapeutic benefit.

Nanochip Could Heal Injuries or Regrow Organs with One Touch – NewsFactor Network

By Dr. Matthew Watson

A novel device that reprograms skin cells could represent a breakthrough in repairing injured or aging tissue, researchers say. The new technique, called tissue nanotransfection, is based on a tiny device that sits on the surface of the skin of a living body. An intense, focused electric field is then applied across the device, allowing it to deliver genes to the skin cells beneath it -- turning them into different types of cells.

That, according to the researchers, offers an exciting development when it comes to repairing damaged tissue, offering the possibility of turning a patient's own tissue into a "bioreactor" to produce cells to either repair nearby tissues, or for use at another site.

"By using our novel nanochip technology, injured or compromised organs can be replaced," said Chandan Sen [pictured above], from the Ohio State University, who co-led the study. "We have shown that skin is a fertile land where we can grow the elements of any organ that is declining."

The ability for scientists to reprogram cells into other cell types is not new: the discovery scooped John Gurdon and Shinya Yamanaka the Nobel Prize in 2012 and is currently under research in myriad fields, including Parkinson's disease.

"You can change the fate of cells by incorporating into them some new genes," said Dr Axel Behren, an expert in stem cell research from the Francis Crick Institute in London, who was not involved in the Ohio research. "Basically you can take a skin cell and put some genes into them, and they become another cell, for example a neuron, or a vascular cell, or a stem cell."

But the new approach, says Sen, avoids an intermediary step where cells are turned into what are known as pluripotent stem cells, instead turning skin cells directly into functional cells of different types. "It is a single step process in the body," he said.

Furthermore, the new approach does not rely on applying an electric field across a large area of the cell, or the use of viruses to deliver the genes. "We are the first to be able to reprogram [cells] in the body without the use of any viral vector," said Sen.

The new research, published in the journal Nature Nanotechnology, describes how the team developed both the new technique and novel genes, allowing them to reprogramme skin cells on the surface of an animal in situ.

"They can put this little device on one piece of skin or onto the other piece of skin and the genes will go there, wherever they put [the device]," said Behrens.

The team reveal that they used the technique on mice with legs that had had their arteries cut, preventing blood flow through the limb. The device was then put on the skin of the mice, and an electric field applied to trigger changes in the cells' membrane, allowing the genes to enter the cells below. As a result, the team found that they were able to convert skin cells directly into vascular cells -with the effect extending deeper into the limb, in effect building a new network of blood vessels.

"Seven days later we saw new vessels and 14 days later we saw [blood flow] through the whole leg," said Sen.

The team were also able to use the device to convert skin cells on mice, into nerve cells which were then injected into the brains of mice who had experienced a stroke, helping them to recover.

"With this technology, we can convert skin cells into elements of any organ with just one touch. This process only takes less than a second and is non-invasive, and then you're off," said Sen.

The new technology, said Behrens is an interesting step, not least since it "avoids all issues with rejection".

"This is a clever use of an existing technique that has potential applications -- but massive further refinement is needed," he said, pointing out that there are standard surgical techniques to deal with blockages of blood flow in limbs.

What's more, he said, the new technique is unlikely to be used on areas other than skin, since the need for an electric current and the device near to the tissue means using it on internal organs would require an invasive procedure.

"Massive development [would be] needed for this to be used for anything else than skin," he said.

But Sen and colleagues say they are hoping to develop the technique further, with plans to start clinical trials in humans next year.

Technion prof inspires Aussie researchers – Australian Jewish News

By JoanneRUSSELL25

INCREDIBLE biomedical breakthroughs including growing beating heart tissue and engineering the worlds first muscle flap transplant with its own blood supply have been achieved by Professor Shulamit Levenberg in her lab at Israels Technion since 2007.

Now researchers at three Australian universities will benefit from collaborative projects with the Technions Dean of Biomedical Engineering, strengthened during her visit to Perth and Sydney from July to mid-August, facilitated by Technion Australia.

Levenberg told The AJN that growing 3D tissue structures that have blood vessels, by using stem cells and biodegradable scaffolds, has so much potential to repair damaged organs, treat diabetes and even spinal cord injuries.

To see the whole piece of cardiac tissue we created in the lab spontaneously beating in front of your eyes was really amazing, Levenberg said.

But what really excited us was that we could create a blood vessel network, which is critical in keeping the implant alive and making revascularisation in the body faster.

Tissue engineering has been used to create islet transplants for diabetes patients, to repair severe tissue injuries in mice and even to produce meat in the lab.

That is a new application, but we are very excited about the regenerative medicine direction, and we hope spinal cord regeneration will happen in humans one day, Levenberg said.

The next step is to make the tissues larger and to move from pre-clinical to clinical trials.

Levenberg came on a Raine Fellowship to the University of Western Australias (UWA) Perkins Institute for Biomedical Research, where she lectured, and connected researchers with Technion colleagues.

We are starting several research projects with UWA on using combinations of biomaterials, and weve got funding for spinal cord regeneration research from the Perth-based Shervington Fund, Levenberg said.

Were also discussing further collaborations in spinal cord research with the University of Technology in Sydney, and we now have a collaboration with Professor Tony Weiss at the University of Sydney, where we are using tropo-elastin that he developed to coat scaffolds.

Technion Australia is in the process of planning a fundraising project to support that collaboration.

A passionate mentor to biomedical engineering students and to girls interested in science, Lewenberg said, I think the most important thing is to show young people that to be a scientist is doable and exciting. My advice is to do what excites them, and not be afraid that something may seem too difficult.

Stem Cells: The Future of Injectable Fillers – Palm Beach Post

By Dr. Matthew Watson

Question: I know stem cells are being used in medicine for regrowing tissue and helping certain diseases, but how do stems cells work for facial rejuvenation?

Answer: The use of stem cells in the cosmetic industry for facial rejuvenation is a relatively recent development. Stem cells for regenerative purposes are being used in traditional medicine for longer. We know that certain types of stem cells can differentiate into tissue-specific cells when provided with the proper stimulus and placed in the right environment.

Protein rich plasma (PRP) is known to contain certain growth factors which can signal stem cells to differentiate. When stem cells are mixed with PRP and injected into skin tissues, these stem cells can differentiate into collagen-producing skin cells. Since much of facial aging is a result of increased collagen breakdown with loss of overall collagen and elastin, collagen-stimulating substances to help restore the collagen balance in our face can give a more refreshed, youthful and rejuvenated appearance.

I use a cutting-edge technology to harvest stem cells from your own body and re-inject them into the facial tissues to restore a more youthful facial appearance. Various tissues in the body are an important source of stem cells, including bone marrow as well as fat or adipose tissue. In my practice, stem cells are harvested from fatty tissue in the stomach or hips in about 10 minutes, using a small syringe and lidocaine solution for numbing.

The stem cells are then mixed with PRP prepared from drawing just one tube of your blood and spinning in the centrifuge for 10 minutes. Its important to realize that these are not fat injections. Its the stem cells that are being harvested from your fatty tissue. The goal is to extract and use the stem cells rather than your actual fat. This entire process takes just 30 to 40 minutes before the stem cells are ready for injection into the face.

Stem cell filler is then injected into the face just like any standard filler. The difference is that 15 to 20 ml or more of stem cell material can be prepared and injected into your face in just one 30 minute session. Another benefit of stem cell fillers, compared to the commercially available fillers, is that stem cells can be injected at various levels within the facial tissues, ranging from very superficial lines of the upper lips and crows feet, to deeper nasolabial folds and marionette lines as well as hollow cheeks and temples. Patients often notice a healthy, youthful glow to their facial skin immediately following treatment.

Unlike commercial fillers which typically contain some foreign component, which is not part of our own bodies, these stem cell filler preparations come from your own body without the risk of allergic reaction. As long as you have some adipose tissue in you flanks or abdomen, a fairy large volume of stem cells for filler injections can be harvested and prepared for use in a single facial rejuvenation injection session.

A one-on-one detailed consultation with a Board Certified Facial Plastic Surgeon is the first step in determining whether you are a good candidate for a stem cell filler versus other commercial fillers.

Dr. Anita Mandal is a double Board Certified Facial Plastic Surgeon practicing since 1998. She exclusively specializes in facial rejuvenation and non-invasive body contouring. In addition to being on the medical staff at Jupiter Medical Center, her offices house both surgical and laser suites. Dr. Mandal is committed to giving her patients the most natural looking results.

Couple renews vows at State Fair after bone marrow donor helps save his life – WTHR

By raymumme

INDIANAPOLIS (WTHR) - People at the Indiana State Fair Saturday got to witness something special.

A husband and wife recommitted their lives to one another right at the Fairgrounds.

The couple also shared with the crowd the important reason they made it to this celebration.

Amid all the fun and food and families at the Indiana State Fair, they brought some magic on the midway.

A love story - two decades strong.

"Today is actually our 20th wedding anniversary," said Derek Fakehany.

Derek and his wife, Amy Van Ostrand, renewed their marriage vows at their favorite summer spot.

And in some ways, the place that illustrates their lives recently.

"The last 18 months have been a roller coaster ride of ups and downs," said bridesmaid Sheri Champagne.

The serious test of their original vows.

"It's very easy to be in love when you're 23, getting married, Amy said. But when you're in your mid-40's and looking at your spouse maybe not making it through the end of the week, you're really tested."

In 2015, Derek was diagnosed with blood cancer.

It was a painful, difficult battle back to health that he nearly lost.

But thanks to a simple swab and a stranger's decision to be the match,

Derek found a donor on the national bone marrow registry.

He had his second transplant 200 days ago.

"That is the reason that Derek is here today. A 26-year-old woman who we never met donated her stem cells to my husband not once, but twice over the last year and that's why he's standing here."

Surrounded by the friends and family who cared for him at his lowest point.

On this day, they watched a stronger Derek and Amy renew promises lived for 20 years.

I declare again that Derek and Amy are for a lifetime of days husband and wife," their minister said, concluding the ceremony.

And in the place where they always feel joy.

Amy asked, "Who wants funnel cake?"

The happy couple and their guests dined on fair food and went for a ride on the Ferris wheel.

Celebrating two milestones - Love and Life.

Northern Ireland mum fighting MS: Russian medics are now my last hope – Belfast Telegraph

Northern Ireland mum fighting MS: Russian medics are now my last hope

BelfastTelegraph.co.uk

A young Co Down mum is bravely undergoing a gruelling stem cell transplant in Russia in what she believes is her last hope of enjoying some quality of life.

http://www.belfasttelegraph.co.uk/news/northern-ireland/northern-ireland-mum-fighting-ms-russian-medics-are-now-my-last-hope-36023340.html

http://www.belfasttelegraph.co.uk/life/features/article36023337.ece/4289a/AUTOCROP/h342/2017-08-12_lif_33652492_I8.JPG

A young Co Down mum is bravely undergoing a gruelling stem cell transplant in Russia in what she believes is her last hope of enjoying some quality of life.

Lindsay Rice (35) from Warrenpoint has exhausted every treatment on the health service - including chemotherapy normally given to cancer patients - in the hope of treating the chronic condition Rapidly Evolving Severe Relapsing Remitting Multiple Sclerosis.

Paralysis and temporary sight loss are just a few of the many debilitating symptoms which have left the mum-of-two unable to enjoy normal family life.

Desperate to get her help, her family launched an appeal on Facebook and Go Fund Me to raise 50,000 to send her to the National Pirogov Medical Surgical Centre in Moscow where she arrived two weeks ago to start her stem cell transplant.

The treatment alone is expected to cost up to 45,000 and, incredibly, in just 12 weeks the family has raised 32,000 towards a 50,000 target thanks to generous support from friends and the public.

Lindsay, who is married to Liam (36), a financial advisor, has two children, Jamie (17) and Olivia (8).

Liam says: "This is her last hope and she is doing it for her family and her kids and that's what she is focusing on. She just wants to be able to live a normal life and do normal things with the family."

Since starting her treatment on August 1 she has been keeping a daily dairy of her progress through a Facebook page - Lindsay's Last Hope.

While the groundbreaking treatment known as HSCT (Haematopoietic Stem Cell Transplant) is not a cure for MS, Lindsay's hope is that it will halt the progression of the disease and stop the frequent and severe relapses which are destroying her health.

Lindsay will spend a month in the clinic, most of it in isolation, and when she comes home she faces a long recovery period when she will have to remain isolated for up to a year due to the risk of infection.

HSCT aims to 'reset' the immune system to stop it attacking the central nervous system. It uses chemotherapy to remove the harmful immune cells and then rebuild the immune system using a type of stem cell found in the patient's bone marrow.

The haematopoietic stem cells used in the treatment can produce all the different cells in the blood, including immune cells. However, they can't regenerate permanently damaged nerves or other parts of the brain and spinal cord.

Lindsay has successfully had over two million stem cells extracted in a tough procedure which involved having a catheter inserted into her jugular vein. She has also had her head shaved this week in preparation for starting chemotherapy today.

The chemotherapy will wipe out her immune system and she will then have her stem cells transplanted back into her blood by a drip to help regrow a new, stronger immune system.

She will then have to spend 10 days in complete isolation while her new immune system builds.

Also, since arriving in Russia she has been told that her MS is now much worse than she realised and is now at the Secondary Progressive stage.

People with Secondary Progressive MS don't tend to recover completely from a relapse and can expect a general worsening of symptoms, making the treatment even more time-critical.

In a further blow, tests have picked up a potentially dangerous three-centimetre active lesion on her spine which wasn't spotted during MRI's here.

Lindsay faces a tough few weeks in her bid to halt the progression of the disease but as her husband Liam explains, the alternative is the prospect of life in a wheelchair: "Lindsay has come through a lot since her teens.

"She had Jamie quite young at 18 and her condition seemed to really deteriorate after that. She went to a lot of consultants and had many tests but it wasn't until after she had Olivia that she was finally diagnosed in 2011.

"She never knows from day to day how it will affect her. Fatigue is the number one problem and that is crippling. I would come home from work and after dinner she has to go to bed, and even sleep doesn't help it.

"It stops her from doing simple things like taking our daughter to the park or taking the dog for a walk.

"Her motability is not as good as an average person and the other big issue is the relapses.

"They have become very frequent and each relapse is worse in terms of how severe it is. During her last one in February she had to go into hospital and also had to use a walking frame.

"A common misconception is that after each relapse you go back to normal but that's not the case. It leaves its mark and any damage done is permanent. The nature of the relapses could leave her in a wheelchair."

It was after her last relapse and having exhausted all options for treatment on the Health Service that Lindsay decided she wanted to try HSCT.

Her neurologist in Belfast supported her decision and the family applied to the Russian clinic just 12 weeks ago expecting to wait up to two years before admission.

They were surprised to be offered a cancellation on August 1 leaving them facing a race against time to raise 50,000 to cover the cost of treatment and expenses.

Liam says: "We thought we would have at least 12 months and up to two years to get the money together and it has been amazing to see how people have rallied round and what they have done just from the kindness of their hearts, especially strangers.

"We've had quizzes and coffee mornings and online auctions and I recently did the Four Peaks challenge with a group of friends. Lindsay's mum and her best friend are organising a lot of events and we still have some way to go but we are amazed at how much has been raised and donated in such a short time."

Liam flew to Russia with Lindsay on July 31 and stayed with her for five days while she underwent tests to determine that she was suitable for the treatment.

It has already been a punishing two weeks for Lindsay who has come through a batch of invasive procedures including having a catheter inserted in her jugular to extract the stem cells.

Liam says: "It is an intense treatment and Lindsay is so positive and coping brilliantly. She got her hair cut short before she went and decided to have it shaved this week before the chemo starts and it falls out.

"She will have to spend 10 days in complete isolation to allow her immune system to build again and that will be tough.

"She will hopefully be home after 30 days and then when she comes home she will have a long recovery and will have to isolate herself from society for up to a year to keep her safe from infection.

"We will have to deep clean the house and we will all have to wear face masks as she can't risk even getting a cold."

Liam is back at work and trying to keep things as normal as possible at home for the couple's two children, who he said are coping well: "Jamie is 17 and approaching adulthood and understands why she is doing it and is okay, but obviously his mum is away and he has his sixth year exam results coming and he misses her.

"Olivia seems to be fine too. She understands her mum has MS, which stops her doing things with her and she knows this treatment is to help her to be a better mother.

"I've been trying as much as possible to keep her occupied with play dates and sleepovers."

The couple have been impressed by the level of care in the clinic and Lindsay has had the chance to meet and get to know other MS patients from all over the world.

Liam has nothing but admiration for her strength and the positive way she is enduring the extreme procedures she faces.

He adds: "Lindsay is the most determined person you could ever possibly meet. She has had bad days and it can be demoralising for her but she is determined to be as positive as she can be.

"It is not a cure. MS doesn't have a cure but we hope it will stop the progress of the disease. We just hope it will halt it by rebooting her immune system and hopefully stop the severe relapses."

Liam adds: "It is desperately hard and stressful for all of us and we have to put a positive spin, in the grand scheme of things it is just for a month of her life."
