The human body is an amazing thing. For each one of us, it's the most intimate object we know. And yet most of us don't know enough about it: its features, functions, quirks, and mysteries. Our series The Body explores human anatomy, part by part. Think of it as a mini digital encyclopedia with a dose of wow.

If you say someone's getting on your nerves, you could just cut to the chase and say they're getting on your sciatic nervethis nerve is plenty big enough for both minor and major irritations. It's the largest nerve in the body, running a lengthy route from each side of your lower spine, deep into your buttock, wrapping around to the back of the thigh and into the foot. Mental Floss spoke to Loren Fishman, medical director of Manhattan Physical Medicine and Rehabilitation in NYC andassociate clinical professor at Columbia Medical School. Here are 13 things we learned about this important part of the nervous system.

No wonder this nerve hurts when it gets irritatedat its biggest point, it's one heck of a large nerve, says Fishman.

The sciatic nerve is more accurately five nerves that come together on the right and left sides of the lower spine. Technically, the fourth and fifth lumbar nerves and the first three nerves in the sacral spine come together and merge into the unified sciatic.

"The sciatic nerve gives feeling and strength to the muscles and skin of the calf and foot, supplies sensation from the joints, bones, and just about everything else below the knee," says Fishman.

The nerve connects the spinal cord with the outside of the thigh, the hamstring muscles in the back of the thigh, and the muscles in your lower leg and feet. This is why sciatic nerve impingement often results in muscle weakness, numbness and/or tingling in the leg, ankle, foot, and toes.

After severe spinal cord injury, the nerve itself is often just fine, but the connection between it and the brain has been severed, Fishman says. Until now, there's been no way to fix such injuries, but "recent work with stem cells has begun to restore the connection in dogs and other animals."

A variety of lower back problems can lead to pain that radiates along the sciatic nerve. Most commonly, sciatica pain is caused when a herniated disc at the L5 (lower lumbar back) irritates the S1 (sacrum) nerve root in the lower spine. The exiting nerve roots are highly sensitive, and the bits of the disc that herniate contain inflammatory proteins such as interleukin and tumor necrosis factor that can also aggravate the nerve.

In a small number of people, a condition called cauda equina syndrome (so named because the nerve bundle at the base of the spinal cord resembles a horse's tail) can masquerade as sciaticabut it also usually causes weakness that extends to bowel or bladder incontinence and sometimes weakness or loss of sensation in the legs that gets progressively worse. In this case, immediate medical attention should be sought, and recovery may not be as quick as with common sciatica.

When the ancient Greek and Roman physicians were treating the pain we now commonly know as sciatica, they believed it stemmed from "diseases of the hip joint," according to a 2007 study in Spinal Cord. It wasn't until 1764, write the authors, "that leg pain of 'nervous' origin was distinguished from pain of 'arthritic' origin."

Among the many treatments Hippocrates and his ilk came up with for this painful condition were: "Fumigations, fasting, and subsequently, laxatives, and ingestion of boiled milk of the female ass." In his Treatise of the Predictions, Hippocrates noted that elderly patients with "cramps and colds at the loin and the legs" would experience their pain for up to a year, whereas young people could be free of pain in about 40 days.

The modern name for the disease, according to Fishman, comes from 15th-century Florence. "They called sciatica ischiatica, since they thought it came from tuberculosis that worked its way down to the ischial tuberosity (the sit-bones)," Fishman says. These medieval doctors had the cause wrong, but the name stuck.

Different researchers in different countries began to make sciatic breakthroughs when doing autopsies on corpses with fractured or herniated discs, where they noticed compression on the sciatic nerve.

A 1991 cross sectional study of 2946 women and 2727 men published in Spine found that neither gender nor body mass made any difference in the likelihood of developing sciatica. Body height did, however, in males between the ages of 50 and 64, with taller men being more likely to have the condition. Other studies have found a similar link [PDF]. Over 5'8"? Your risk is higher.

Sciatica has a surprisingly common negative impact on daily life. "Low back pain and sciatica are the second biggest reason for lost days of workjust behind the common cold," says Fishman.The condition is most commonly found in people over 50 andrarely seen in anyone under 20 years oldand then it most often has a genetic cause.

FREMONT, Calif., Aug. 08, 2017 (GLOBE NEWSWIRE) Asterias Biotherapeutics, Inc. (NYSE MKT:AST) today announced that Lucas Lindner of Eden, Wisconsin, a quadriplegic patient who has regained functional use of his fingers, hands and lower arms after receiving the companys investigational stem cell therapy for complete cervical spinal cord injury, AST-OPC1, will throw out the ceremonial first pitch of a Major League Baseball game in Milwaukee on Sunday, August 13th.

Lucas has been an inspiration to our employees at Asterias who have worked so hard to bring AST-OPC1 to where it is now being administered to patients in a clinical trial, as well as to thousands of others who have seen his story on the internet or on television, said Mike Mulroy, President and CEO of Asterias. We are excited about the progress he has made since receiving 10 million cells of AST-OPC1 and look forward to cheering him on as he takes the field before the game.

Lucas suffered a severe spinal cord injury when his car swerved off the road into a tree to avoid hitting a deer in May 2016. He was flown to the hospital and received immediate surgery to stabilize his spine. He was left without the ability to move his limbs below the neck and upper arms.

In June 2016, Lucas received 10 million cells of AST-OPC1 in Asterias ongoing SCiStar Phase 1/2a clinical study by Shekar N. Kurpad, MD, PhD, Sanford J. Larson Professor and Chairman, Department of Neurosurgery at the Medical College of Wisconsin and Director of the Froedtert & Medical College of Wisconsin Spinal Cord Injury Program. Lucas has since regained the ability to move triceps, hands and fingers.

As of his latest follow-up visit (12 months following administration of AST-OPC1), Lucas has achieved two motor levels of improvement on one side of his body. As suggested by existing research, patients with severe spinal cord injuries that show two motor levels of improvement on at least one side may regain the ability to perform daily activities such as feeding, dressing and bathing, which significantly reduces the overall level of daily assistance needed for the patient and associated healthcare costs.

Throwing out the first pitch at a Major League game is not something I could have imagined a year ago, said Lucas. I want to show everyone that there is hope that spinal cord injury patients can regain function. I am looking forward to going back to school, pursuing my dream of working in the IT field and living independently someday.

When I first met Lucas about a year ago, he had some use of his arms and little to no use of his hands or fingers, said Dr. Kurpad. The fact that he is throwing out the first pitch at a Major League Baseball game is amazing. It illustrates the strides medical science is starting to make in helping paralyzed patients regain useful function. Im very encouraged by the early results we are seeing with AST-OPC1 and am grateful for the improvement Lucas has made.

Asterias has now completed enrollment and dosing in four of the five planned SCiStar study cohorts and enrolled twenty-two patients in the SCiStar study. Twenty-seven patients have been administered AST-OPC1 after including patients from a previous Phase 1 safety trial and results-to-date continue to support the safety of AST-OPC1. In June 2017, Asterias reported 9 month data from the AIS-A 10 million cell cohort that showed improvements in arm, hand and finger function observed at 3-months and 6-months following administration of AST-OPC1 were confirmed and in some patients further increased at 9-months. The company intends to complete enrollment of the entire SCiStar study later this year, with multiple safety and efficacy readouts anticipated during the remainder of 2017 and 2018.

About the SCiStar Trial

The SCiStar trial is an open-label, single-arm trial testing three sequential escalating doses of AST-OPC1 administered at up to 20 million AST-OPC1 cells in as many as 35 patients with subacute, C-4 to C-7, motor complete (AIS-A or AIS-B) cervical SCI. These individuals have essentially lost all movement below their injury site and experience severe paralysis of the upper and lower limbs. AIS-A patients have lost all motor and sensory function below their injury site, while AIS-B patients have lost all motor function but may have retained some minimal sensory function below their injury site. AST-OPC1 is being administered 21 to 42 days post-injury. Patients will be followed by neurological exams and imaging procedures to assess the safety and activity of the product.

The study is being conducted at eight centers in the U.S. and the company plans to increase this to up to 12 sites to accommodate the expanded patient enrollment. Clinical sites involved in the study include the Medical College of Wisconsin in Milwaukee, Shepherd Medical Center in Atlanta, University of Southern California (USC) jointly with Rancho Los Amigos National Rehabilitation Center in Los Angeles, Indiana University, Rush University Medical Center in Chicago, Santa Clara Valley Medical Center in San Jose jointly with Stanford University, Thomas Jefferson University Hospital, in partnership with Magee Rehabilitation Hospital, in Philadelphia, and UC San Diego Health in San Diego.

Asterias has received a Strategic Partnerships Award grant from the California Institute for Regenerative Medicine, which provides $14.3 million of non-dilutive funding for the Phase 1/2a clinical trial and other product development activities for AST-OPC1.

Additional information on the Phase 1/2a trial, including trial sites, can be found at http://www.clinicaltrials.gov, using Identifier NCT02302157, and at the SCiStar Study Website (www.SCiStar-study.com).

About AST-OPC1

AST-OPC1, an oligodendrocyte progenitor population derived from human embryonic stem cells originally isolated in 1998, has been shown in animals and in vitro to have three potentially reparative functions that address the complex pathologies observed at the injury site of a spinal cord injury. These activities of AST-OPC1 include production of neurotrophic factors, stimulation of vascularization, and induction of remyelination of denuded axons, all of which are critical for survival, regrowth and conduction of nerve impulses through axons at the injury site. In preclinical animal testing, AST-OPC1 administration led to remyelination of axons, improved hindlimb and forelimb locomotor function, dramatic reductions in injury-related cavitation and significant preservation of myelinated axons traversing the injury site.

In a previous Phase 1 clinical trial, five patients with neurologically complete, thoracic spinal cord injury were administered two million AST-OPC1 cells at the spinal cord injury site 7-14 days post-injury. Based on the results of this study, Asterias received clearance from FDA to progress testing of AST-OPC1 to patients with cervical spine injuries in the current SCiStar study, which represents the first targeted population for registration trials. Asterias has completed enrollment in the first four cohorts of this study. Results to date have continued to support the safety of AST-OPC1. Additionally, Asterias has recently reported results suggesting reduced cavitation and improved motor function in patients administered AST-OPC1 in the SCiStar trial.

Cuorips, a Japan-based cardiac therapy developer spun out from Osaka University, has secured an undisclosed amount from pharmaceutical firm Daiichi Sankyo.

The investment was made as part of an agreement that gives the corporate an option right for the worldwide commercialisation of Cuorips technology, called iPS-derived cardiomyocyte sheet, a cell therapy for patients suffering from severe heart failure.

The treatment uses induced pluripotent stem (iPS) cells, which can be generated directly from a donors mature cells and differentiated into any organ. It offers an alternative to patients who would otherwise require a heart or artificial heart transplant.

The technology is based on research led by Yoshiki Sawa, professor at the Graduate School of Medicines Department of Cardiovascular Surgery.

Sawa developed the therapy through his participation in the Research Center Network for Realization of Regenerative Medicine, operated by the research organisation Japan Agency for Medical Research and Development.

Cuorips is currently gearing up for clinical research and an investigator-initiated clinical trial.

Los Angeles Police Officer Matthew Medina. AJPRESS

LOS ANGELES Its been almost five months since Matthew Medina first learned about his rare blood disease and how his Filipino heritage is affecting his chances of being cured.

Earlier this year, the 40-year-old police officer was going about his normal duties as part of the Los Angeles Police Departments (LAPD) Harbor Division gang unit. By his side was his close friend, Dante Pagulayan, also an officer with the department.

The two have known each other since they were about 14 years old in high school and ended up going to Cal State Long Beach together, before eventually joining the LAPD. It was at the college, Pagulayan shared, where Medina met his wife Angelee with whom the latter now has two beautiful daughters.

Matt is one of the funniest guys I know, Pagulayan said about his friend during a recent interview with the Asian Journal. If you want to have a good time, hes going to be your guy.

Currently, Medina remains in quarantine after having been diagnosed with aplastic anemia, a rare disease that claims 600-900 people in the United States each year, according to the Aplastic Anemia and MDS International Foundation (AA/MDS). The fact that hes Filipino presents a larger challenge.

Finding a donor

Aplastic anemia, or bone marrow failure, is a blood disease in which bone marrow fails to make enough blood cells for the body.

According to AA/MDS, it can affect anyone regardless of race or gender but is diagnosed more often in children, young adults, and older adults. It also appears more often in Asian Americans.

For Medina, the disease seemed to come out of nowhere. Matt was a very precautious guy, said Pagulayan about Medinas health habits. He always took care of himself, took vitamins, went to the doctor He was that kind of guy.

Radiation and chemotherapy, toxic chemical exposure, use of certain drugs, and autoimmune disorders are some factors known to injure bone marrow, thus affecting blood cell reproduction. But for the most part, theres no telling what causes aplastic anemia.

Getting a bone marrow transplant is the only cure for aplastic anemia. However, finding a match is a major obstacle that those diagnosed are forced to face.

In order for a transplant to be successful, both the donor and beneficiary need to share eight human leukocyte antigens (HLA), or cell markers. This explains why more chances of success happen between a donor and receiver of the same ethnic background.

Chances of recovery

For Medina and many others, chances of recovery are greatly reduced simply due to the number of minority-group members registered to be potential bone marrow matches.

Out of the 12 million people registered, only 0.5 percent were Filipino, said Pagulayan. It was quite a surprise.

As of 2016, the number of Asians recorded in Be The Matchs registry made up only six percent of the total registered, shared Ayumi Nagata, Recruitment Manager of Asians for Miracle Marrow Matches (A3M).

The lowest percentage came from those who identified as Native Hawaiian/Other Pacific Islander their percentage hovered at 0.1 percent. The largest group at 57 percent with 7.8 million comprise of those who are white.

While transplants between family members have worked, its rarely the case, according to Mixed Marrow, a foundation dedicated to increasing bone marrow and blood cell donors for patients of multi-ethnic descent. Finding a match within the family is only successful 30 percent of the time, leaving 70 percent searching elsewhere.

Nagata has encountered a number of cultural and religious reasons that explain the low number of Asian registrants, but the lack of familiarity and awareness remain the biggest culprits.

Organizations like Mixed Marrow and A3M are working together to disprove these misconceptions by focusing on increasing awareness through outreach within cultural contexts.

One common misconception is that donating marrow is painful. Nagata informed that most procedures are done through nonsurgical Peripheral Blood Stem Cell (PBSC) donations where cells are collected through the blood rather than the bone itself.

Umbilical cord blood is another source, and Be The Match lists a number of hospitals that collect the blood for a public cord blood bank.

Hope for Medina

There are now currently 1,270 ethnically diverse, and 101 Caucasian registrants through Medinas campaign, reported Nagata. With the help of Medinas support group and community, theres hope that the numbers can increase.

Since the start of Medinas match campaign, two others in need of bone marrow transplants were able to find a match.

On June 25, Medina personally posted on his Match4Matt Facebook campaign page, Even if they never find a match for me, I can say that this campaign has been a success since it has already helped save the lives of at least two people (so far).

For Medina, the search continues but he remains optimistic. On his Facebook post, he reported that his blood cell counts have increased and he hopes that the upward trend continues toward remission. I am not out of the woods yet, he added. There is still a long road to recovery ahead, but the proverbial light at the end of the tunnel is definitely getting brighter.

But as Pagulayan said, the only way to really revert it is through a bone marrow transplant. Medinas condition can change just as quick as how he found out he had the disease.

To those thinking about registering to be a match, Pagulayan said to think of a loved one and what would happen if you woke up and found out they had the disease.

To join a registry, anyone up to 60 years old can sign up, but donors between ages 18-44 are preferred. There are also medical conditions that may make someone ineligible. The process itself takes less than five minutes, according to Nagata. As Pagulayan put it, It takes less time to swab your cheeks than it takes to fill out the paperwork.

Fil-Am LAPD officer still in need of bone marrow match - Inquirer.net

KOCHI: Shabas T S, a 23-year-old electrical engineer from Kochi, did not know that a stem cell donor registration camp he attended two years ago just to bunk class would become a turning point in his life. A year after registering with DATRI, India's largest adult unrelated blood stem cell donor's registry, Shabas was informed by the organization that his stem cells are perfect match to 9-year-old Manasvi Karamchedu from Hyderabad who was diagnosed with Thalassemia Major when she was five months old.

On Thursday, when Shabas met a fully-recovered Manasvi at Cochin Palace Hotel here at a meet arranged by DATRI, he was an elated lot. "I have no words to express my feeling. I feel so proud that a simple gesture from my part saved a life," said Shabas.

Manasvi's father Kiran could not control his tears when he hugged the youth who gave his daughter a new lease of life. "My wife and I were shattered when Manasvi was diagnosed with Thalassemia Major. She needed blood transfusions every week and the permanent solution was a blood stem cell transplant," he said.

"We came to know about DATRI when we lost all the hopes. Last year, we got the transplant done at Apollo Hospital, Chennai. Shabas and DATRI have gifted Manasvi a new life. Now, she has two birthdays and two birthplaces," said Kiran. "Ever since the transplant last year, we were looking forward to meeting Shabas. I am happy that DATRI has arranged it now," he added.

Blood stem cell transplant is the solution to those diagnosed with blood cancer and other blood-related disorders. But many are reluctant to come forward to donate blood stem cells. Donation can be done through two methods peripheral blood stem cell (PBSC) donation and bone marrow donation.

Shabas, who went for PBSC, said, "My family was very supportive and I was able to get back to my daily activities immediately after the procedure".

Bone marrow transplants are used in serious blood disorders, especially cancers, when the needed doses of chemotherapy or radiation would be so high it would damage or destroy the stem cells in the marrow.

WINTER HAVEN For 14 years, Dr. Christopher Miller has been treating patients at Bond Clinic where he specializes in endocrinology, diabetes and metabolism. Many local people have met him at Bonds diabetes clinic or in nearby Eloise where he volunteers at Angel Cares free clinic.

Organizers of a Be The Match drive are hoping that those who have benefited from his care, including families and friends of patients, will turn out to honor him Saturday by volunteering to be a bone marrow donor.

He received a shocking, out-of-the-blue diagnosis and is in need of a bone marrow match, said Ashley Scanlan, marketing director for Bond Clinic.

Bone marrow is the soft tissue inside bones where blood cells are produced. Transplants are used in serious blood disorders, especially cancers, when the needed doses of chemotherapy or radiation would be so high it would damage or destroy the stem cells in the marrow.

Be The Match, a national nonprofit organization that is part of the National Marrow Donor Program, is the largest registry matching donors with those in need of a marrow transplant, said Marc Silver, community engagement representative for Be The Match. It also provides support for patients and donors, information for health care professionals and conducts research.

Nearly 70 percent of people needing a marrow transplant do not have a match within their families so the registry was set up to provide a resource for matches.

The event is from 8to 11 a.m. Saturday at the Bond Clinic Main Campus, 500 E. Central Ave., Winter Haven.

Registering to be a donor is a simple process, filling out some paperwork and taking a mouth swab, Scanlan said.

Volunteers should be between 18 and 44 years old, generally in good health and be willing to donate to any patient in the future, Scanlan said.

People are asking why the cutoff is 44, but they have found that age group has the best success in transplants, Scanlan said.

People of other ages are invited to come Saturday and write a note toMiller or make a financial donation, which would go either to the American Cancer Society or to the local Angel Care clinic, she said.

Bobbie Skukowski, an advanced registered nurse practitioner who leads Bonds diabetes clinic, said, Dr. Miller is an excellent physician and an excellent teacher. He was a fellow at Emory University and has taught us all so much; he has brought up the level of diabetes care at Bond Clinic and in the Winter Haven area in general.

"He is very good with his patients and right-on in his care, she said.

If a person is later selected as a potential match, there is no cost to the donor, Scanlan said. And the potential donor can later decide to withdraw from the registry.

The paperwork will ask several questions, including whether the potential donor is willing to donate to any patient in need, willing to donate to a stranger, and willing to donate 20 to 30 hours if found to be a perfect match.

If the potential donor meets the criteria, a mouth swab is taken and later analyzed for a match.

While years ago, being a bone marrow donor was a complicated procedure, now it typically is simple, handled much like a blood donation, Scanlan said.

Over 80 percent of the donations are non-invasive, said Be The Matchs spokesman Silver.

Be The Match literature explains that the donor is given injections of a drug, filgrastim, for five days leading up to the donation to increase the number of stem cells in the blood.

Then, on the day of the donation, the donor goes through a procedure similar to donating blood platelets at a blood center. Blood is taken out of one arm, passed through a machine that collects the blood-forming stem cells, and then the red and white blood cells are returned to the donors other arm through a needle. Typically it takes eight hours.

Donors often have a headache or muscle aches for a few days 22 percent recover within two days, 53 percent within a week, 93 percent within a month, 99 percent within three months and a very few people can take as long as a year to recover, according to Be The Match.

Less than 20 percent of the time, we do a hip aspiration, which is a more complicated procedure and involves having anesthesia in an operating room, Silver said.

Be The Match literature explains that, in those cases, needles are used to withdraw liquid marrow from both sides of the back of the pelvic bone. Typically, the donor stays at the hospital from early morning to late afternoon, or occasionally overnight for observation.

Be The Match helped match 6,200 patients for marrow and cord blood transplants last year and added 472,000 new potential donors to the registry, according to the organization.

Bone marrow drive to help and honor Bond Clinic physician - The Ledger

Bone Marrow Donors Needed

Paula (Fitzgerald) Silvia of Middletown has been diagnosed with myeloid dysplasia syndrome (MDS), a form of blood cancer where the bone marrow cells do not mature into healthy blood cells. Paula received this devastating news at the end of June. Nothing seemed particularly out of sorts; she was travelling with her family, working, going to the beach and doing all her volunteer activities. Only indications were catching more colds and a little tired but Paulas life was always busy and she does so much for everyone, she should be tired.

Paula has started her first round of chemotherapy. Every four weeks, she has five consecutive days of chemotherapy infusion. However, it is only a temporary treatment. A bone marrow transplant is needed to cure the disease.

A bone marrow registration drive is being held on Sunday, September 17 from 4:00pm to 7:00pm at Fenner Hall, 15 Fenner Ave, Newport, for this purpose. It is being organized by her family and friends and is in conjunction with Dana-Farber Cancer Institute and http://www.BeTheMatch.org, a national bone marrow donor registry.

The first source for bone marrow matches is a sibling or child, if they fall in the age range, but Paulas family members were not a match. More than 35,000 people in the United States are diagnosed each year with leukemia, anemias, myelodysplastic disorders and other life-threatening diseases requiring treatment with a blood stem cell or bone marrow transplant. About 70 percent of bone marrow transplant recipients must rely on an unrelated donor. Finding a compatible donor is a challenge. The opportunity to register and/or donate will help many patients in need..

Donors must be 18 to 44, and be willing to donate to any patient in need.To join the registry, potential donors must complete paperwork at the drive and have a cheek swab taken. If unable to attend, donors are asked to go towww.bethematch.orgto sign up, or visit any RI Blood Center.

Paula (Fitzgerald) grew up in Newport in the Fifth Ward, attending Newport schools, graduating from Rogers in 1968.

Bone Marrow Drive To Benefit Paula Fitzgerald Silvia On Sunday, September 17th - Newport Buzz

Advancellssays its stem cell-based therapy completely reversed multiple sclerosis (MS) in an Indian pilot trial with only one MS patient.

The patient, Rahul Gupta, was diagnosed with MS seven years ago and has since suffered multiple relapses. His disease was progressing fast and he was quickly losing his ability to walk. Gupta, who lives in New Zealand, approached Advancells a company based in the Indian state of Uttar Pradesh that specializes in the use of stem cells for therapeutic purposes.

After my last relapse, I became determined to look for alternative treatments for multiple sclerosis,Gupta said in a press release. I started looking on the net and found that stem-cell therapy [offers] hope for people suffering with MS [and] that it is safe and would not harm me in any way. I was determined to undergo stem-cell treatment, as my illness was progressing very quickly.

Gupta enrolled inAdvancells adult stem-cell therapy program as the trials single patient. In the procedure carried outin June at a New Delhi clinic doctors isolated stem cells from his bone marrow and re-infused them back into the patientat specific points. Apart from this procedure, Gupta underwent only physiotherapy and a dietary routine.

Straight after the treatment I saw major improvements, he said. I could walk a lot better, could climb stairs which I was unable to do after 2012 and even go on the treadmill.

Dr. Lipi Singh, head of technology at Advancells, said the company is frequently approached by MS patients from around the world who want to participate in its program.

Patient selection is a key criterion for us and Rahul suited the criteria perfectly, Singh said. He is young and still at a moderate level of the disease and in a very positive frame of mind. Patients at this stage are best suited for this kind of treatment and thus we decided to accept him as a pilot case.

Singh now expects to review Guptas response sometime this fall.

It will take approximately three months for us to review changes in the magnetic resonance imaging of the patient, but the drastic changes in symptoms clearly are an indication of the fact that the treatment is working and could become a hope for millions of patients across the world who are suffering from this disease. Singh said.

He added: This is a good start to a lengthy research phase, but it seems that we are on the right track and hopefully we will be able to make a significant contribution in eradicating not only MS but a host of untreatable diseases existing today.

GREENVILLE Onboard the next SpaceX cargo spacecraft launching to the International Space Station (ISS) from Pad 39A at the Kennedy Space Center will be a commercial research system owned and operated by Techshot Inc. The equipment will conduct regenerative medicine experiments onboard the station before returning to Earth in the same capsule for a splashdown off the coast of Southern California approximately 30 days later.

Techshots ADvanced Space Experiment Processor (ADSEP) is a device approximately the size of a microwave oven that contains three separate modules, each of which simultaneously can process experiments in three separate on-orbit replaceable automated mini-laboratory cassettes. Two of the three cassettes on the mission will conduct research for a team led by Robert Schwartz, Ph.D., from the University of Houston.

Funded by the Center for the Advancement of Science in Space (CASIS), the study will evaluate a new approach to growing human tissue for transplant. The microgravity environment onboard the ISS could improve cell growth and development and 3D tissue formation, enabling discoveries that will advance translational disease treatments. Previous studies on Earth by Schwartz and his collaborators at the Texas Heart Institute and the Baylor College of Medicine have found that low gravity environments help specially programmed stem cells move toward becoming new heart muscle cells, which may be used to repair damaged hearts on Earth.

The third cassette contains an experiment conducted by and for Techshot itself. The company is developing a 3D bioprinter for the ISS known as the Techshot BioFabrication Facility (BFF), which it expects to launch to the station near the end of 2018. Critical to the success of the printer will be the ability to provide nutrients and mechanical stress for organs and tissues it manufactures in space strengthening them and keeping them viable for transplantation back on Earth.

Approximately 36 hours prior to launch, Techshot scientists in a laboratory at the Kennedy Space Center will 3D print a one centimeter thick construct consisting of stem cells and heart muscle cells. Theyll then place it inside the prototype BFF cell culturing subsystem, which for this mission is temporarily housed inside an ADSEP cassette. The printer used in the lab will be the same modified nScrypt unit that was the first to 3D print cardiac constructs with adult human stem cells in microgravity aboard an aircraft in parabolic flight. Video captured inside the cassette during the month-long experiment, and the tissue itself which is expected to have developed its own micro blood vessels will be evaluated for effectiveness after return from space.

Techshots space bioprinting program leverages its terrestrially based technologies for cell isolation and vascular graft development, and its decades long experience culturing cells in space, said Techshot Chief Scientist Eugene Boland, Ph.D., in a news release. Being able to test our novel approach for culturing 3D printed cells more than a year before we fly the whole BFF is invaluable. The data from this mission will get us one step closer toward our goal of helping eliminate organ shortages.

Founded in 1988, Techshot Inc., develops technologies used in the aerospace, defense and medical industries. Through its Space Act Agreement with NASA, and its role as an official CASIS Implementation Partner, the company provides equipment and services that help federal, institutional and industrial customers live and work in space. http://www.Techshot.space

SOUTH SAN FRANCISCO, CA--(Marketwired - August 08, 2017) - VistaGen Therapeutics Inc. (NASDAQ: VTGN), a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders, announced today that the Company has received a Notice of Allowance from the U.S. Patent and Trademark Office (USPTO) for U.S. Patent Application No. 14/359,517 regarding proprietary methods for producing hematopoietic precursor stem cells, which are stem cells that give rise to all of the blood cells and most of the bone marrow cells in the body, with potential to impact both direct and supportive therapy for autoimmune disorders and cancer.

The breakthrough technology covered by the allowed U.S. patent was discovered and developed by distinguished stem cell researcher, Dr. Gordon Keller, Director of the UHN's McEwen Centre for Regenerative Medicine in Toronto, one of the world's leading centers for stem cell and regenerative medicine research and part of the University Health Network (UHN), Canada's largest research hospital. Dr. Keller is a co-founder of VistaGen and a member of the Company's Scientific Advisory Board. VistaGen holds an exclusive worldwide license from UHN to the stem cell technology covered by the allowed U.S. patent.

"We are pleased to report that the USPTO has allowed another important U.S. patent relating to our stem cell technology platform, stated Shawn Singh, Chief Executive Officer of VistaGen. "Because the technology under this allowed patent involves the stem cells from which all blood cells are derived, it has the potential to reach the lives of millions battling a broad range of life-threatening medical conditions, including cancer, with CAR-T cell applications and foundational technology we believe ultimately will provide approaches for producing bone marrow stem cells for bone marrow transfusions. As we continue to expand the patent portfolio of VistaStem Therapeutics, our stem cell technology-focused subsidiary, we enhance our potential opportunities for additional regenerative medicine transactions similar to our December 2016 sublicense of cardiac stem cell technology to BlueRock Therapeutics, while focusing VistaStem's internal efforts on using stem cell technology for cost-efficient small molecule drug rescue to expand our drug development pipeline."

About VistaGenVistaGen Therapeutics, Inc. (NASDAQ: VTGN), is a clinical-stage biopharmaceutical company focused on developing new generation medicines for depression and other central nervous system (CNS) disorders. VistaGen's lead CNS product candidate, AV-101, is in Phase 2 development, initially as a new generation oral antidepressant drug candidate for major depressive disorder (MDD). AV-101's mechanism of action is fundamentally different 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. National Institute of Mental Health (NIMH) in a small 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 an inadequate response to standard, FDA-approved antidepressants. Dr. Maurizio Fava of Harvard University 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, and levodopa-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.

About VistaStemVistaStem Therapeutics is VistaGen's wholly-owned subsidiary focused on applying human pluripotent stem cell (hPSC) technology, internally and with third-party collaborators, to discover, rescue, develop and commercialize (i) proprietary new chemical entities (NCEs), including small molecule NCEs with regenerative potential, for CNS and other diseases and (ii) cellular therapies involving stem cell-derived blood, cartilage, heart and liver cells. VistaStem's internal drug rescue programs are designed to utilize CardioSafe 3D, its customized cardiac bioassay system, to develop small molecule NCEs for VistaGen's pipeline. To advance potential regenerative medicine (RM) applications of its cardiac stem cell technology, in December 2016, VistaStem exclusively sublicensed to BlueRock Therapeutics LP, a next generation regenerative medicine company established in 2016 by Bayer AG and Versant Ventures, rights to certain proprietary technologies relating to the production of cardiac cells for the treatment of heart disease. In a manner similar to its exclusive sublicense agreement with BlueRock Therapeutics, VistaStem may pursue additional collaborations and potential RM applications of its stem cell technology platform, including using blood, cartilage, and/or liver cells derived from hPSCs, for (i) cell-based therapy, (ii) cell repair therapy, and/or (iii) tissue engineering.

Technologies that reprogram one type of cell to perform the role of another hold a huge amount of potential when it comes to medicine, possibly changing the way we treat everything from Parkinson's to pancreatic cancer to brain tumors. One broader outcome of all of this could be a game-changing ability to repair and restore damaged tissue and organs. Scientists are now reporting a promising advance in the area, in the form of patch that they say can use an electric pulse to turn skin cells into the building blocks of any organ.

The new technology has been dubbed tissue nanotransfection and was developed by scientists at The Ohio State University's Wexner Medical Center. According to the researchers, it uses the skin as a kind of regenerative cellular factory, where it produces any cell type that can then be used to repair injured or aging tissues, organs and blood vessels. It consists of a nanotechnology-based chip that is applied to the skin, which is then struck with a short electric pulse to deliver genetic instructions into the cells of the tissue.

"These are genes that induce tissue plasticity allowing the flexibility to direct the fate," Chandan Sen, first author of the paper, explains to New Atlas. "Thus, for example, skin cells can be directed to form blood vessels, or neural cells, or some other cell of interest."

We have seen a number of promising approaches to reprogramming cells for various regenerative health purposes. In 2012, a Japanese researcher won a Nobel Prize for his discovery that skin cells from mice could be harvested and converted into stem cells in the lab, work that has inspired a number of exciting breakthroughs since.

But according to Sen, one of the main advantages his tissue nanotransfection technology holds over other approaches is the fact that the cell conversion takes place in the body. This avoids the thorny issue of immune response, in which the host cells react to the newcomers and possibly attack them, something that can cause a raft of complications.

"Ours is reprogramming of not just cells but tissue within the live body under immune surveillance," he tells us. "Our strategy must co-operate with physiological factors to achieve the end goal."

That end goal is still a while away, but his team is making promising progress all the same. It put the technology to the test on animals, and in one experiment involving mice with badly injured legs lacking blood flow, it was able to convert skin cells into vascular cells. Within about a week, the legs featured active blood vessels. By the second week they were saved.

In a separate experiment, the team was also able to use the technology to reprogram skin cells into nerve cells, which were then injected into brain-injured mice to assist with stroke recovery.

"This is difficult to imagine, but it is achievable, successfully working about 98 percent of the time," said Sen. "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. The chip does not stay with you, and the reprogramming of the cell starts. Our technology keeps the cells in the body under immune surveillance, so immune suppression is not necessary."

The team hopes to move onto clinical trials some time next year, but Sen tells us they must first test the technology on larger animals and design the device to work on humans.

A University of Chicago-based research team has overcome challenges that have limited gene therapy and demonstrated how their novel approach with skin transplantation could enable a wide range of gene-based therapies to treat many human diseases.

In a study inthe journal Cell Stem Cell, the researchers provide proof-of-concept. They describe gene-therapy administered through skin transplants to treat two related and extremely common human ailments: Type 2 diabetes and obesity.

We resolved some technical hurdles and designed a mouse-to-mouse skin transplantation model in animals with intact immune systems, said study author Xiaoyang Wu, assistant professor in the Ben May Department for Cancer Research at the University of Chicago. We think this platform has the potential to lead to safe and durable gene therapy in mice and, we hope, in humans, using selected and modified cells from skin.

Beginning in the 1970s, physicians learned how to harvest skin stem cells from a patient with extensive burn wounds, grow them in the laboratory, then apply the lab-grown tissue to close and protect a patients wounds. This approach is now standard. However, the application of skin transplants is better developed in humans than in mice.

The mouse system is less mature, Wu said. It took us a few years to optimize our 3-D skin organoid culture system.

This study is the first to show that an engineered skin graft can survive long term in wild-type mice with intact immune systems. We have a better than 80 percent success rate with skin transplantation, Wu said. This is exciting for us.

The researchers focused on diabetes because it is a common non-skin disease that can be treated by the strategic delivery of specific proteins.

They inserted the gene for glucagon-like peptide 1 (GLP1), a hormone that stimulates the pancreas to secrete insulin. This extra insulin removes excessive glucose from the bloodstream, preventing the complications of diabetes. GLP1 can also delay gastric emptying and reduce appetite.

Using CRISPR, a tool for precise genetic engineering, they modified the GLP1 gene. They inserted one mutation, designed to extend the hormones half-life in the blood stream, and fused the modified gene to an antibody fragment so that it would circulate in the blood stream longer. They also attached an inducible promoter, which enabled them to turn on the gene to make more GLP1, as needed, by exposing it to the antibiotic doxycycline. Then they inserted the gene into skin cells and grew those cells in culture.

When these cultured cells were exposed to an air/liquid interface in the laboratory, they stratified, generating what the authors referred to as a multi-layered, skin-like organoid. Next, they grafted this lab-grown gene-altered skin onto mice with intact immune systems. There was no significant rejection of the transplanted skin grafts.

When the mice ate food containing minute amounts of doxycycline, they released dose-dependent levels of GLP1 into the blood. This promptly increased blood-insulin levels and reduced blood-glucose levels.

When the researchers fed normal or gene-altered mice a high-fat diet, both groups rapidly gained weight. They became obese. When normal and gene-altered mice got the high-fat diet along with varying levels of doxycycline, to induce GLP1 release, the normal mice grew fat and mice expressing GLP1 showed less weight gain.

Expression of GLP1 also lowered glucose levels and reduced insulin resistance.

Together, our data strongly suggest that cutaneous gene therapy with inducible expression of GLP1 can be used for the treatment and prevention of diet-induced obesity and pathologies, the authors wrote.

When they transplanted gene-altered human cells to mice with a limited immune system, they saw the same effect. These results, the authors wrote, suggest that cutaneous gene therapy for GLP1 secretion could be practical and clinically relevant.

This approach, combining precise genome editing in vitro with effective application of engineered cells in vivo, could provide significant benefits for the treatment of many human diseases, the authors note.

We think this can provide a long-term safe option for the treatment of many diseases, Wu said. It could be used to deliver therapeutic proteins, replacing missing proteins for people with a genetic defect, such as hemophilia. Or it could function as a metabolic sink, removing various toxins.

Skin progenitor cells have several unique advantages that are a perfect fit for gene therapy. Human skin is the largest and most accessible organ in the body. It is easy to monitor. Transplanted skin can be quickly removed if necessary. Skins cells rapidly proliferate in culture and can be easily transplanted. The procedure is safe, minimally invasive and inexpensive.

There is also a need. More than 100 million U.S. adults have either diabetes (30.3 million) or prediabetes (84.1 million), according the Centers for Disease Control and Prevention. More than two out of three adults are overweight. More than one out of three are considered obese.

Additional authors of the study were Japing Yue, Queen Gou, and Cynthia Li from the University of Chicago and Barton Wicksteed from the University of Illinois at Chicago. The National Institutes of Health, the American Cancer Society and the V Foundation funded the study.

The Wall Street Journal editorial board reported yesterday that the Health Resources and Service Administration (HRSA) regulation which sought to ban compensation for blood-forming stem cell donors has been defeated. This represents a small but significant victory for advocates of compensating organ donors a practice that remains outlawed by the National Organ Transplant Act (NOTA).

The crux of HRSAs rulemaking was a move to redefine blood-forming stem cells drawn from the bloodstream as an organ, no different from the bone marrow found within the bone, and thus under NOTAs purview. Our friends at the Institute for Justice (IJ) rightly argued for years that such a move was nonsensical and illegal. Blood and plasma are explicitly exempt from NOTAs ban on donor compensation, and as such donations of some subpart of the blood, including stem cells, should also be exempt.

The battle to kill the then-pending regulation heated up late last year, as HRSA neared its deadline to finalize the rule. The Niskanen Center formally joined IJs efforts in November, when we released a report called Bone Marrow Mismatch: How compensating bone marrow donors can end the transplant shortage and save lives. The report highlighted the enormous gap between bone marrow demand and supply under the current regime of voluntary donation, and argued against the applicability of the core ethical concerns advanced by HRSA. Our research and Hill event on the issue culminated in a listening session with HRSA officials, in which we argued that the social cost of enacting the rule was well in excess of $100 million, and thus worthy of delay for a deeper cost-benefit appraisal.

Its unclear what happened next. HRSAs hard December 18 deadline came and went, with a final rule that appeared to have been written but not formally submitted to the Federal Register. Perhaps it was the incoming administration, or the threat of litigation should the rule go through, or our research which provided a clear rationale for postponement. Regardless, the rule entered a strange purgatory, which is where it stayed until HHS formally withdrew the rule last week.

The Niskanen Center has received communications from a federal employee who believes our research was to some degree responsible for the rules ultimate repeal. That said, my research was simply part of a multi-pronged and multi-year effort to oppose the rule, led early on byIJ, the entrepreneur Doug Grant, the economist Mario Macis, and Peter Jaworski, the business ethicist and creator of DonationEthics.com.

The view of the Niskanen Center is that economic rights include the right to receive compensation for organ donations. NOTA therefore deserves a much deeper legal challenge. But in the meantime, lets celebrate the defeat of this regulation as a clear example of what it means to make small steps toward a better world.

Every evening when Aadya watches children in the neighborhood play, my heart breaks. My daughter too was once an energetic presence rushing about. I know that Aadya longs to join them.

It started after Aadyas second birthday. She got high fever and rashes all over. The local doctor called it skin allergy and prescribed medicines. The fever persisted, and we sought another medical opinion.

The diagnosis was devastating. B Cell Acute Lymphoblastic Leukaemia a cancer that affects the immune system. Our only hope now lies in the contributions of caring strangers through ketto.org.

B Cell Acute Lymphoblastic Leukaemia. Big sounding medical terms that we knew nothing about, but by the look on the doctors face, clearly it was serious.

Acute lymphoblastic leukemia affects, breaks down the bodys ability to fight diseases. The cancer starts in the bone marrow, where new blood cells grow. These cells grow very fast and the bone marrows capacity to make normal cells is reduced.

The doctor said Aadya needed treatment immediately, or else the cancer would spread. From March to December 2016, she was under the care of Dr. Shweta Bansal at the Sir H.N.Reliance Foundation Hospital and Research Centre in Mumbai. Ten months is a long time for a grown person. To watch our only child suffer through so many blood tests and chemotherapy treatments was very painful and difficult.

After ten months, the treatment ended and we were full of hope that Aadya would begin to recover. Then just four months later, in April 2017, we got the terrible news that the leukemia had relapsed. Since then, Aadya has been visiting the hospital for chemotherapy and tests, every 15-30 days.

Today Aadya is three years old and it hurts us to see her childhood being taken away. She barely eats, feels tired and weak all the time, and gets bruised easily. Even the slightest exposure to infection can be dangerous so we mostly keep her at home. She has missed many days of school and plays indoors. Any exposure to dust is dangerous so we have to make sure that her clothes, food, and toys are kept dust-free at all times.

Aadyas hope is a Bone Marrow Transplant, which costs a staggering Rs 25 lakh. We have started a fundraising page with ketto.org, counting on peoples sense of humanity to help us with this life-saving surgery.

So far we have spent Rs 15 lakh on Aadyas chemotherapy treatments, medications, and hospital visits. I am a housewife and my husband earns Rs 25,000 working as a back office employee. We are completely dependent on his salary and had to raise the money for the treatment by taking loans, borrowing from family members and friends and through insurance. All that we have managed to raise until now has been used up in the treatment.

A Bone Marrow Transplant surgery will replace Aadyas damaged bone marrow with healthy bone marrow stem cells, enabling her to lead a normal, healthy life. Her father is a matching and willing donor but we need to put together Rs 25 lakh in the next one month. We have no means of raising that kind of money.

For Aadya to survive, that operation has to be done in one months time. For over a year now, Aadya has been fighting a tough, long battle. Now there is hope that this operation will finally end her nightmare and lead to that one final miracle when we can take our baby home.

We have started a fundraising page with Ketto.org in Aadyas name, in the hope that people will come forward and help us raise the funds for this surgery.

Please help us pay for her BMT by logging on to Ketto.org.

Help us to bring Aadya home.

Researchers demonstrate a process known as tissue nanotransfection (TNT). When it comes to healing, this TNT is the bomb.

It's usually bad news to have something growing on your skin, but new technology uses that all important layer as a sort of garden to "grow" whatever types of cells your body might need to treat an injury or disease, be it in a limb or even the brain.

Researchers atthe Ohio State University Wexner Medical Centerhave developed a nanochip that uses a small electrical current to deliver new DNA or RNA into living skin cells, "reprogramming" them and giving them a new function.

"It takes just a fraction of a second. You simply touch the chip to the wounded area, then remove it,"Chandan Sen, director of the Center for Regenerative Medicine and Cell-Based Therapies at Ohio State, said in a statement. "At that point, the cell reprogramming begins."

In a study published in the journal Nature Nanotechnology, Sen's team used a technology called Tissue Nanotransfection (TNT) to create new blood vessels in pigs and mice with badly injured limbs that lacked blood flow.

They zapped the animals' skin with the device, and within about a week, active blood vessels appeared, essentially saving the creatures' legs. The tech was also used to create nerve cells from skin that were then harvested and injected into mice with brain injuries to help them recover.

"By using our novel nanochip technology, injured or compromised organs can be replaced," Sen said. "We have shown that skin is a fertile land where we can grow the elements of any organ that is declining."

While it sounds futuristic, reprogramming skin cells is not a new idea. The ability to change skin into pluripotent stem cells, sometimes called "master" cells, earned a few scientists a Nobel Prize half a decade ago. But the new nanochip approach improves upon that discovery by skipping the conversion from skin to stem cell and instead converting a skin cell into whatever type of cell is desired in a single step.

"Our technology keeps the cells in the body under immune surveillance, so immune suppression is not necessary," Sen says.

By now I think we've all learned that beauty is only skin deep, but it might take a while to learn that the same could go for cures, at least if the system works just as well on people.

Next up, the scientists hope to find out by continuing to test their technology in human trials. The aim is that it could eventually be used to treat all sorts of organ and tissue failure, including diseases like Parkinson's and Alzheimers.

The chip has not been tested in humans, but it has been used to heal wounds in mice. Wexner Medical Center/The Ohio State University hide caption

The chip has not been tested in humans, but it has been used to heal wounds in mice.

Scientists have created an electronic wafer that reprogrammed damaged skin cells on a mouse's leg to grow new blood vessels and help a wound heal.

One day, creator Chandan Sen hopes, it could be used to be used to treat wounds on humans. But that day is a long way off as are many other regeneration technologies in the works. Like Sen, some scientists have begun trying to directly reprogram one cell type into another for healing, while others are attempting to build organs or tissues from stem cells and organ-shaped scaffolding.

But other scientists have greeted Sen's mouse experiment, published in Nature Nanotechnology on Monday, with extreme skepticism. "My impression is that there's a lot of hyperbole here," says Sean Morrison, a stem cell researcher at the University of Texas Southwestern Medical Center. "The idea you can [reprogram] a limited number of cells in the skin and improve blood flow to an entire limb I think it's a pretty fantastic claim. I find it hard to believe."

When the device is placed on live skin and activated, it sends a small electrical pulse onto the skin cells' membrane, which opens a tiny window on the cell surface. "It's about 2 percent of the cell membrane," says Sen, who is a researcher in regenerative medicine at Ohio State University. Then, using a microscopic chute, the chip shoots new genetic code through that window and into the cell where it can begin reprogramming the cell for a new fate.

Sen says the whole process takes less than 0.1 seconds and can reprogram the cells resting underneath the device, which is about the size of a big toenail. The best part is that it's able to successfully deliver its genetic payload almost 100 percent of the time, he says. "No other gene delivery technique can deliver over 98 percent efficiency. That is our triumph."

Chandan Sen, a researcher at Ohio State University, holds a chip his lab created that has reprogrammed cells in mice.

To test the device's healing capabilities, Sen and his colleagues took a few mice with damaged leg arteries and placed the chip on the skin near the damaged artery. That reprogrammed a centimeter or two of skin to turn into blood vessel cells. Sen says the cells that received the reprogramming genes actually started replicating the reprogramming code that the researchers originally inserted in the chip, repackaging it and sending it out to other nearby cells. And that initiated the growth of a new network of blood vessels in the leg that replaced the function of the original, damaged artery, the researchers say. "Not only did we make new cells, but those cells reorganized to make functional blood vessels that plumb with the existing vasculature and carry blood," Sen says. That was enough for the leg to fully recover. Injured mice that didn't get the chip never healed.

When the researchers used the chip on healthy legs, no new blood vessels formed. Sen says because injured mouse legs were was able to incorporate the chip's reprogramming code into the ongoing attempt to heal.

That idea hasn't quite been accepted by other researchers, however. "It's just a hand waving argument," Morrison says. "It could be true, but there's no evidence that reprogramming works differently in an injured tissue versus a non-injured tissue."

What's more, the role of exosomes, the vesicles that supposedly transmit the reprogramming command to other cells, has been contentious in medical science. "There are all manners of claims of these vesicles. It's not clear what these things are, and if it's a real biological process or if it's debris," Morrison says. "In my lab, we would want to do a lot more characterization of these exosomes before we make any claims like this."

Sen says that the theory that introduced reprogramming code from the chip or any other gene delivery method does need more work, but he isn't deterred by the criticism. "This clearly is a new conceptual development, and skepticism is understandable," he says. But he is steadfast in his confidence about the role of reprogrammed exosomes. When the researchers extracted the vesicles and injected them into skin cells in the lab, Sen says those cells converted into blood vessel cells in the petri dish. "I believe this is definitive evidence supporting that [these exosomes] may induce cell conversion."

Even if the device works as well as Sen and his colleagues hope it does, they only tested it on mice. Repairing deeper injuries, like vital organ damage, would also require inserting the chip into the body to reach the wound site. It has a long way to go before it can ever be considered for use on humans. Right now, scientists can only directly reprogram adult cells into a limited selection of other cell types like muscle, neurons and blood vessel cells. It'll be many years before scientists understand how to reprogram one cell type to become part of any of our other, many tissues.

Still, Morrison says the chip is an interesting bit of technology. "It's a cool idea, being able to release [genetic code] through nano channels," he says. "There may be applications where that's advantageous in some way in the future."

A Chip That Reprograms Cells Helps Healing, At Least In Mice - NPR

A med-tech startup has developed a fast and easy way to treat certain burn wounds with stem cells. This technology is developed by German researcher Dr. Jrg Gerlach. He is the worlds first ever person who use a patients stem cells to directly heal the skin. The technique is meant to reduce the healing time and minimize complications, with aesthetically and functionally satisfying outcomes. There are no scars, no residual pain and its like there wasnt any burn to start with. Its not less than a miracle.

The medical technology startup has now transformed the proof-of-concept device from a complicated prototype into a user-friendly product called a SkinGun, which it hopes doctors will be able to use outside of an experimental setting. RenovaCare CEO Thomas Bold believes, the SkinGun can compete with, or even replace, todays standard of care. The sprayer allows us to have a generous distribution of cells on the wound, explained Roger Esteban-Vives, director of cell sciences at RenovaCare.

RenovaCares SkinGun sprays a liquid suspension of a patients stem cells onto a burn or wound in order to re-grow the skin without scars. Stem-cell methods helped cut this risk by quickening healing and providing a source of new skin from a very small area. Cell Mist method gets a greater yield from its harvest than mesh grafting, a more common way to treat burns. At a maximum, grafting can treat six times the size of its harvest area. Cell Mist can cover 100 times its harvest area.

When dispensing cells over a wound, its important that they make the transition without any damage. Damaged cells reduce the effectiveness of the treatment.

High cell viability also contributes to faster healing. When a wound heals naturally, cells migrate to it to build up the skin. That process can take weeks.

Stem cells have tremendous promise to help us understand and treat a range of diseases, injuries and other health-related conditions.

There is still a lot to learn about stem cells, however, and their current applications as treatments are sometimes exaggerated by the media and other parties who do not fully understand the science and current limitations

Beyond regulatory matters, there are also limitations to the technology that make it unsuitable for competing with treatments of third-degree burns, which involve damage to muscle and other tissue below the skin.

When burn victims need a skin graft they typically have to grow skin on other parts of their bodies. This is a process that can take weeks. A new technique uses stem cells derived from the umbilical cord to generate new skin much more quickly.The umbilical cord consists of a gelatinous tissue that contains uncommitted mesenchymal stemcells (MSC)

Research is underway to develop various sources for stem cells, and to apply stem-cell treatments for neurodegenertive diseasesand conditions such as diabetes, heart disease, and other conditions.

Tens of thousands of grafts are performed each year for burn victims, cosmetic surgery patients, and for people with large wounds having difficulty healing. Traditionally, this involves taking a large patch of skin (typically from the thigh) and removing the dermis and epidermis to transplant elsewhere on the body. Burns victims are making incredible recoveries thanks to a revolutionary gun that sprays stem cells on to their wounds, enabling them to rapidly grow new skin. Patients who have benefited say their new skin is virtually indistinguishable from that on the rest of the body.

Thomas Bold, chief executive of RenovaCare, the company behind SkinGun, said: The procedure is gentler and the skin that regrows looks, feels and functions like the original skin.

If you are planning to have stem cell treatments dont forget to remember these points

Stem cell researchers are making great advances in understanding normal development. They are trying to figure out what goes wrong in disease and developing and testing potential treatments to help patients. They still have much to learn. However, about how stem cells work in the body and their capacity for healing. Safe and effective treatments for most diseases, conditions and injuries are in the future.
