New York, California (PRWEB) August 28, 2014

The Manhattan Regenerative Medicine Medical Group announces a series of free public seminars on the use of adult stem cells for various degenerative and inflammatory conditions. They will be provided by Dr. Thomas A. Gionis, Surgeon-in-Chief, and, Dr. Nia M. Smyrniotis, Medical Director.

The seminars will be held on Wednesday, September 3, 2014, at 2pm and 4pm at the City Limits Diner, at 135 Harvard Avenue, Stamford, CT 06902. Please RSVP at (917) 410-7391.

The Manhattan Regenerative Medicine Medical Group is an affiliate of the Miami Stem Cell Treatment Center, which abide by investigational protocols using adult adipose derived stem cells (ADSCs) which can be deployed to improve patients quality of life for a number of degenerative and chronic inflammatory conditions and diseases. ADSCs are taken from the patients own adipose (fat) tissue (found within a cellular mixture called stromal vascular fraction (SVF). ADSCs are exceptionally abundant in adipose tissue. The adipose tissue is obtained from the patient during a 15 minute mini-liposuction performed under local anesthesia in the doctors office. SVF is a protein-rich solution containing mononuclear cell lines (predominantly adult autologous mesenchymal stem cells), macrophage cells, endothelial cells, red blood cells, and important Growth Factors that facilitate the stem cell process and promote their activity.

ADSCs are the body's natural healing cells - they are recruited by chemical signals emitted by damaged tissues to repair and regenerate the bodys injured cells. The Manhattan Regenerative Medicine Medical Group and the Miami Stem Cell Treatment Center only use Adult Autologous Stem Cells from a person's own fat No embryonic stem cells are used. Current areas of study include: Emphysema, COPD, Asthma, Heart Failure, Parkinsons Disease, Stroke, Multiple Sclerosis, Lupus, Rheumatoid Arthritis, Crohns Disease, and degenerative orthopedic joint conditions. For more information, or if someone thinks they may be a candidate for one of the adult stem cell protocols offered by the Manhattan Regenerative Medicine Medical Group or Miami Stem Cell Treatment Center, they may contact Dr. Gionis or Dr. Nia directly at (917) 410-7391, or see a complete list of the Centers study areas at: http://www.MiamiStemCellsUSA.com or http://www.NYStemCellsUSA.com.

About Manhattan Regenerative Medicine Medical Group and the Miami Stem Cell Treatment Center: The Manhattan Regenerative Medicine Medical Group and The Miami Stem Cell Treatment Center is an affiliate of the Cell Surgical Network (CSN); they are located in Manhattan, NY; Miami, Boca Raton, and Orlando, Florida. We provide care for people suffering from diseases that may be alleviated by access to adult stem cell based regenerative treatment. We utilize a fat transfer surgical technology to isolate and implant the patients own stem cells from a small quantity of fat harvested by a mini-liposuction on the same day. The investigational protocols utilized by the Manhattan Regenerative Medicine Medical Group and the Miami Stem Cell Treatment Center have been reviewed and approved by an IRB (Institutional Review Board) which is registered with the U.S. Department of Health, Office of Human Research Protection; and the study is registered with Clinicaltrials.gov, a service of the U.S. National Institutes of Health (NIH).

(RTTNews.com) - Asterias Biotherapeutics Inc. (ASTY.OB) said Wednesday that it has received clearance from the U.S. Food and Drug Administration or FDA to initiate a Phase 1/2a clinical trial of its product, AST-OPC1, in patients with complete cervical spinal cord injury.

The company stated that the approved trial follows the successful completion of the Phase 1 clinical study of the product, and is designed to assess safety and activity of escalating doses of AST-OPC1 in patients with complete cervical spinal cord injuries, the first targeted indication for AST-OPC1 and the first of future product registration clinical trials.

AST-OPC1 is a population of cells derived from human embryonic stem cells (hESCs) that contains oligodendrocyte progenitor cells (OPCs). OPCs and oligodendrocytes perform supportive functions for nerve cells in the central nervous system. The foundation for this newly cleared Phase 1/2a clinical trial comes from results from the Phase 1 clinical trial of AST-OPC1, which met its primary endpoints of safety and feasibility when administered to five patients with neurologically-complete, thoracic spinal cord injury.

These five patients were administered a low dose of two million AST-OPC1 cells and have been followed to date for 2 to 3 years. No serious adverse events were observed associated with the delivery of the cells, the cells themselves, or the short-course immunosuppression regimen used.

The company noted that the new Phase 1/2a clinical trial will be an open-label, single-arm study testing three escalating doses of AST-OPC1 in 13 patients with subacute, C5-C7, neurologically-complete cervical spinal cord injury. These individuals have essentially lost all sensation and movement below their injury site with severe paralysis of the upper and lower limbs.

AST-OPC1 will be administered 14 to 30 days post-injury. Patients will be followed by neurological exams to assess the safety and activity of the product. Selection of the clinical trial sites is well underway and the Company expects to begin patient enrollment during the first quarter of 2015.

The new clinical trial differs from the original clinical study in that doses up to 10 times higher will be tested. In addition, the trial will focus on patients with neurologically-complete cervical spinal cord injuries. Because of the anatomy of the spinal cord and the existence of more sensitive outcomes measures to assess movement of the arms and hands, it is currently believed that detection of efficacy is much more likely to occur in patients with cervical injuries. It is this patient population that Asterias anticipates will be the target for the first registration clinical trials of AST-OPC1.

The results of the Phase 1/2a clinical trial are expected to provide support for a Phase 2b expansion study that will be conducted to more thoroughly demonstrate safety and efficacy of the product.

Manila:

A Philippine Catholic bishop Wednesday urged donors to research on Lou Gehrigs Disease to ensure that their money does not go to unethical studies involving stem cells.

The pastoral guidance was issued as more Filipinos take part in the viral fundraising ice bucket challenge for Lou Gehrigs Disease or Amyotrophic Lateral Sclerosis (ALS), a degenerative disease that affects nerve cells in the brain and spinal cord.

Archbishop Socrates Villegas said donors must make a clear and unequivocal declaration that their donation is made on condition that none of it is applied to research that involves the use of embryonic stem cells in vitro. Catholics who participate in the challenge and who make donations to this research must also demand of fund-raisers and organizers an assurance that none of the donations made will be applied to researches that are ethically reproved, he added.

Villegas said that as long as the research was ethical, the Church would even encourage Catholics to donate, noting, The importance of ALS research cannot be overstated. Research must proceed, for so many suffer. Several top government officials, business leaders and other Filipino personalities have recently taken up the ALS ice bucket challenge, drenching themselves in cold water to raise money for research on the illness.

Filipino bishop urges donors not to support stem cell research

Jeanne Loring and her Scripps Research Institute colleagues transplanted a set of cells into the spinal cords of mice that had lost use of their hind limbs to multiple sclerosis. As the experimentalists expected, within a week, the mice rejected the cells. But after another week, the mice began to walk.

We thought that they wouldnt do anything, says Loring, who directs theCenter for Regenerative Medicineat Scripps. But as her lab has since shown numerous times, and published in Stem Cell Reports, something that these particular so-called neural precursor cells dobeforethe immune system kicks them out seems to make the mouse better.

The cells Lorings team used are derived from induced pluripotent stem cells, which are mature cells, such as skin cells, that have been coaxed with a combination of chemicals to return to an earlier stage of development.

Induced pluripotent cells, also known as iPS cells, pose a number of opportunities for medicine. For instance, Loring is using iPS cells from Parkinsons disease and multiple sclerosis patients to reconstitute cell types that may be damaged in people with those conditions. She is also using them to test how certain drugs or treatments may affect damaged cells in people with conditions such as autism spectrum disorders.

Loring (front row, center) with the Loring Lab Group at the Center for Regenerative Medicine

Loring says no viable long-term treatments exist for the diseases her team has been working on, including Alzheimers disease, Parkinsons disease, and multiple sclerosis, Thats where the need is, she says.

The neural precursor cells that Loring has been using in the mice with MS are young cells that havent quite gotten to the point of being nerves yet. Only certain types of these cells have such a dramatic Lazarus-like effect on the affected mice, but Lorings team can readily identify them based on DNA analysis.

Even so, theyre not yet ready to treat human MS patients with the approach, she says. First, the researchers want to identify what the cells producea protein, perhaps, or a set of proteinsthat allows the mice to walk.

For other diseases, however, researchers are closer to being ready to transplant working versions of reprogrammed cells into sick people.

Could Reprogrammed Cells Fight 'Untreatable' Diseases?

Stem cell technology pioneer,DefiniGEN Ltdhas joined the Pfizer-inspired European Bank for induced pluripotent stem cells (EBiSC) consortium.

The consortium comprises 26 partners, and has been newly-formed with support from the Innovative Medicines Initiative (IMI) and the European Federation of Pharmaceutical Industries and Associations (EFPIA).

DefiniGen, a Cambridge University spin-out that has raised millions, represents one of the first commercial opportunities to arise from the universitys expertise in stem cells and is based on the research of Dr Ludovic Vallier, Dr Tamir Rashid and Professor Roger Pedersen of the universitys Anne McLaren Laboratory of Regenerative Medicine.

The EBiSC iPS cell bank will act as a central storage and distribution facility for human iPS cells, to be used by researchers across academia and industry in the study of disease and the development of new therapeutics. DefiniGENs role will be to validate EBiSC iPS cell lines by generating liver hepatocyte cells for toxicology, disease modelling, and regenerative medicine applications.

Dr Marcus Yeo, CEO of DefiniGEN, said: We are delighted to be a part of this ground-breaking consortium which will provide a crucial platform resource to enable the realisation of the full potential of iPS technology.

Conceptualised and coordinated by Pfizer Ltd in Cambridge, UK and managed by Roslin Cells Ltd in Edinburgh, the EBiSC bank aims to become the European go to resource for high quality research grade human iPS cells.

Today, iPS cells are being created in an increasing number of research programmes underway in Europe, but are not being systematically catalogued and distributed at the necessary scale to keep pace with their generation, nor to meet future demand.

The 35 million project will support the initial build of a robust, reliable supply chain from the generation of customised cell lines, the specification to internationally accepted quality criteria and their distribution to any global qualified user, ensuring accessibility to consistent, high quality tools for new medicines development.

Ruth McKernan, CSO of Pfizers Neusentis research unit in Cambridge, said: We are excited to be a part of this precompetitive collaboration to build a sustainable repository of high quality human iPS cell lines.

For many areas of research in academia and in industry, understanding the biological basis of disease heterogeneity is the next horizon. A bank of well-characterised iPS lines with strong relevance to the entire research community will help us all in our mission to bring therapies to patients.

Scientists who hoped to replicate the results of potentially groundbreaking stem-cell research have been unsuccessful to date, researchers at the Riken Center for Developmental Biology in Kobe, Japan, said Wednesday, according to the Associated Press. Detailed in two papers published in the journal Nature in January, the research was initially heralded as a breakthrough in the field of stem-cell biology, but was later met with skepticism after other institutions attempts to mirror its results failed. The authors of the papers and Nature retracted them in June.

Now, the center behind the papers says its recent efforts to confirm certain aspects of the research have failed. Researchers have conducted 22 experiments thus far, but we could not confirm the emergence of cells in the conditions described in [lead researcher Haruko Obokatas] papers, Riken said in a statement cited by Agence France-Presse. The center anticipates it will continue trying to confirm certain aspects of the research until next March, AP said.

The two papers published in Nature described a simple process for producing stem cells using an acid-based solution. Researchers said they successfully created pluripotent embryonic stem cells -- cells that can be grown into any kind of cell, including human organ tissue -- from mature skin cells. However, it was later revealed that researchers had misrepresented some of their data.

The controversy surrounding the research team who published the papers took an unexpected turn this month when one of the papers authors, Yoshiki Sasai, committed suicide at the Riken institute.

STEM CELL THERAPY: with DR ANDREW J. ROCHMAN - Video

MIAMI - When Bruce Daily woke up after having lumbar surgery a year ago, he realized he couldn't move the right side of his body.

"It took me a long while to figure out I wasn't gonna walk again," he said. "I knew I was down."

Daily, 69, had gone in for lumbar surgery at the University of Miami hospital and had an ischemic stroke while under anesthesia. An ischemic stroke results from an obstruction in a blood vessel that blocks the blood from getting to the brain.

Because he was unconscious, he missed the four-to-five hour-window to apply the tissue plasminogen activator, or tPA, the only medication available to treat ischemic strokes. The medication dissolves the clot, restoring blood flow to the brain.

But while he missed that chance, he was right on time to meet Dr. Dileep Yavagal, a neurosurgeon who practices at the University of Miami and Jackson Memorial hospitals. Yavagal was enrolling patients in RECOVER-stroke, a clinical trial treating recent stroke patients with stem cells from their bone marrow and applying them directly into the carotid artery, one of two arteries that supply the neck and head with blood. Daily was one of 47 patients nationwide who qualified for the study.

The study is funded by Cytomedix, the company that developed the technology to extract stem cells from bone marrow. The firm chose Yavagal to lead a national blind study at the end of 2012.

Yavagal enrolled 13 patients at the University of Miami/Jackson Memorial Hospital, between the end of 2012 and January of 2014. So far, the initial three-month results have revealed that the marrow cells are not doing any damage, and there was no clear difference between those who received the cells and those who didn't. The study's one-year final results will be revealed in January.

"There is severe need for developing treatment for ischemic stroke, and stem cells are the most promising," said Yavagal, whose own research is still in its initial phase, focusing on using a healthy donor's bone marrow stem cells versus the patient's own marrow.

Stroke, the leading cause of adult disability in the United States, and the No. 4 cause of death in the country, causes 130,000 deaths a year in the U.S., according to the Centers for Disease Control and Prevention.

Yavagal, associate professor of clinical neurology and neurosurgery and the director of interventional neurology at the University of Miami's Miller School of Medicine, said that restricted mobility or loss of speech resulting from a moderate to severe stroke can be devastating because patients often become dependent on someone else for daily activities.

(RTTNews.com) - GlaxoSmithKline plc (GSK, GSK.L) said Tuesday the U.S. Food and Drug Administration approved a supplemental New Drug Application for the once-daily use of Promacta (eltrombopag) in patients with severe aplastic anaemia who have had an insufficient response to immunosuppressive therapy.

Severe aplastic anaemia, or SAA, is a blood disorder where the bone marrow fails to make enough red blood cells, white blood cells, and platelets. Eltrombopag, an oral thrombopoietin (TPO) receptor agonist, works by helping to induce proliferation and differentiation of bone marrow stem cells to increase production of blood cells.1

"FDA approval of Promacta addresses a significant treatment need for this very rare but serious blood disorder in those who have failed current treatment options," said Paolo Paoletti, president of Oncology, GSK.

Promacta gained Breakthrough Therapy designation status from the FDA in January 2014 and Priority Review in April 2014. Today's approval by the FDA is based on results from an investigator-sponsored Phase II study conducted by the National Heart, Lung and Blood Institute at the National Institutes of Health.

Stem cells heal pooches in pain MIKE MATHER

NICK REED/Fairfax NZ

HAPPY HOUND: Shiloh with owner Adele Holland. She is a different dog since having stem cell injections to relieve arthritis pain, Holland says.

Three years ago australian shepherd dog Shiloh was diagnosed with a severe case of degenerative arthritis that left her limping slowly towards her deathbed.

As time went on, and to the dismay of her Horotiu family, Shiloh became increasingly stiff, was soon no longer able to jump, could barely walk without pain, and eventually had to be carried outside to the toilet.

But, remarkably, the 10-year-old pet is not only still alive today, she is walking and jumping without a trace of pain.

It's a physical improvement her owner Adele Holland describes as "nothing short of a miracle".

Shiloh's recovery is something dozens of arthritic Waikato dogs have now experienced after stem cell injections, a treatment technique adopted by Hamilton veterinarian practice CareVets.

Veterinarian Ivan Aleksic said Shiloh was the first dog to receive stem cells. His practice had successfully repeated the $2600 treatment on more than 40 dogs with arthritis. He described stem cells as "the body's own repair cells".

"They have the ability to divide and differentiate into many different types of cells based on where they are needed throughout the body. They can divide and turn into tissues such as skin, fat, muscle, bone, cartilage and nerve to name a few.

Stem cell treatment helps arthritic dogs

Q: My daughter plays college soccer and ruptured her ACL. The coaches mentioned stem cell injections that some big-name athletes have used to recover from injuries. Should we consider them? Paige R., Chicago

A: Professional athletes are always looking for the fastest way to heal their injuries. In 2010, Yankees pitcher Bartolo Colon was treated for a torn rotator cuff with injections of fat and bone marrow adult stem cells; he's playing for the Mets this season. And in 2011, Denver Broncos' Peyton Manning opted for injections of his own fat stem cells to try to get over a neck injury. Two years later, he had a record-breaking season and took the Broncos to the Super Bowl. But does this mean the injections worked? Nope.

Colon's agent attributes the pitcher's career turnaround to a re-dedication to the game, not the injections, and Manning followed up his stem cell treatment with major surgery and intense rehab (done in secret).

There's just no solid evidence yet that injections of adult bone marrow (or fat) stem cells effectively regenerate and repair damaged tendons or ligaments, and you cannot be certain of what the injections contain or their side effects. They often are delivered in an unregulated environment and aren't FDA-approved.

We suspect your daughter is headed for reconstructive surgery and six months of rehab. Then she needs to learn new ways to move so she reduces stress on her knees. One metastudy found that two ACL-injury-prevention regimens were effective: Sportsmetrics promotes leg and core strength, increases vertical jump height and may improve speed and agility; the Prevent Injury and Enhance Performance (PEP) program, makes a big difference in the flexion strength of the knee. Both improve athletic performance tests and reduce injury rates. Rehab is tough, and there are no shortcuts, but we bet your daughter has the grit to do it!

Q: I had Roux-en-Y gastric bypass surgery last year, and my blood glucose levels were almost normal even before I lost any weight. How is that possible? Marty Z., Jupiter, Florida

A: Congrats, Marty. We hope you're continuing to have such good results. It is amazing that bypassing part of your stomach and intestine could have such an immediate effect on your blood sugar levels, and just recently researchers have figured out why that happens sometimes. It seems to have something to do with the bacteria that live in your digestive tract, also called your gut biome.

Roux-en-Y surgery bypasses most of the stomach and the first part of the small intestine, called the duodenum. That's where a lot of your gut bacteria live and where they influence gut hormones that regulate appetite, insulin use, glucose levels and more. So right away, the surgery decreases levels of hormones that regulate appetite; you can eat less without being hungry. That alone lowers glucose levels and increases the effectiveness of your body's insulin supply.

Also, when you have diabetes, your gut bacteria are thrown out of balance; the bad guys overwhelm the good guys (like bifidobacteria and lactobacillus). And that means the hormones that affect how cells get and use glucose can't do their job. The glucose stays in your bloodstream instead of being used as fuel by your cells. But once a lot of the bad gut bacteria are bypassed, your gut biome snaps back into balance and the bacteria and hormones work together to regulate blood sugar levels.

So we suggest you keep your gut biome balanced and happy with a healthy diet of five or more servings of fruits and veggies a day. Asparagus, garlic, cooked onions and dandelion greens deliver prebiotics that help good-for-you gut bacteria thrive. Fermented foods like nonfat kefir and kimchi contain healthful probiotics. Also, avoid saturated fats and added sugars they just make your biome miserable. And we like daily spore probiotic supplements containing bacillus coagulans GBI-30, 6086 and lactobacillus GG.

TORONTO -- Canadian doctors have begun using stem cell transplants to treat "stiff person syndrome," a rare neurological condition in which a patient's leg and other muscles suddenly contract painfully, often leaving them immobilized like a tin soldier.

The disorder, which affects an estimated one in a million people, occurs when the immune system turns against a person's own tissues, in this case attacking cells in the brain and spinal cord.

Stem cell transplants have been used to treat patients with other auto-immune diseases, among them multiple sclerosis, scleroderma and Crohn's disease, but this may be the first time the procedure has been employed to alleviate the symptoms of stiff person syndrome, or SPS, the researchers reported Monday in the journal JAMA Neurology.

SPS is characterized by episodes of stiffness in the muscles and painful muscle spasms, which can be brought on by stress, loud noises or emotional distress. Some people with the disorder are so disabled they are unable to walk or move and may isolate themselves at home to avoid triggering an attack.

"Sometimes this happens when they're startled," said Dr. Harry Atkins of the Blood and Marrow Transplant Program at the Ottawa Hospital, who headed a team that transplanted stem cells into two women with the disease.

"So you can imagine walking across the street and someone honks the horn and you can't move, or you start falling and because your muscles can't move, you just fall and you hurt yourself," Atkins said Monday from Ottawa.

"It really does provide a barrier with just going on with your life."

Tina Ceroni of Toronto is one of the two SPS patients who had the stem-cell transplant -- and she said it has given back her life.

The personal fitness trainer, now 36, started getting severe symptoms in her late 20s. Initially she was diagnosed with hyponatremia, or low blood sodium, thought to be related to her heavy training schedule for a half-ironman competition.

ABC Kellie van Meurs (3rd from R) died of a heart attack last month while receiving stem cell treatment in Moscow.

Rogue operators in Australia and overseas are charging thousands of dollars for ineffectual stem cell treatments, a leading stem cell research group has warned.

And Stem Cells Australia says there is a growing number of patients going overseas for stem cell treatments which are limited in Australia.

A loophole in the therapeutic goods legislation means that doctors are legally allowed to treat patients, both here and overseas, with their own stem cells even if that treatment is unsafe or has not been proven effective through clinical trials.

Stem Cells Australia believes that dozens of doctors in Australia offer the questionable treatments.

"They're selling treatment without any proof of benefit, and without any proof of safety," Associate Professor Megan Munsie, a stem cell biologist at the University of Melbourne, told 7.30.

Annie Leverington was diagnosed with multiple sclerosis in 2007.

She was once a talented flamenco dancer and worked as a court stenographer.

But in 2002 she noticed something was wrong when her fingers started to "drop" during long trials.

Then her feet started to go.

As Prof Noel Caplice describes it, a revolutionary new system that avoids putting patients through heart bypass operations was literally a back-of- the-garage effort.

A cardiologist in Cork, he came up with the treatment when working as a cardiologist at the Mayo Clinic seven years ago. During this time, Caplice and an engineer friend worked on prototype meshes and attaching these to stents.

The treatment introduces cells that encourage the body to make new blood vessels that grow past the blockage, actually reversing the disease in as little as three or four weeks.

The treatment may also offer hope for patients suffering from other cardiovascular disorders such as peripheral artery disease, a common risk in diabetes. And, because it uses the patients own cells, there is no question of rejection, says Caplice, director of University College Corks Centre for Research in Vascular Biology.

This would represent a major step forward in the treatment of coronary artery disease, he adds. Instead of open-heart surgery and stitching in arteries to bypass a blockage, it causes the body to grow its own bypass. He is leading the research, which also involves the Mayo Clinic in the US, and the team has published a paper describing the work in the current issue of the journal Biomaterials.

He came up with the idea when working as a cardiologist at the Mayo Clinic seven years ago, he says.

One area we were interested in was patients who were inoperable, patients who were too ill to face open-heart surgery and who had no options. That represents about 20 to 25 per cent of all patients with coronary artery disease.

He was a scientist physician while at the Mayo as he is now, doing research but also working with patients, and he ran his own laboratory. He originally thought of introducing stem cells to encourage blood vessel growth, but when injected they go everywhere, you cant direct them in the body.

Caplice is also a consultant cardiologist at Cork University Hospital.

Bypassing surgery for new cardiac treatment

"By directly reprogramming cells we've managed to produce an artificial cell type that, when transplanted, can form a fully organised and functional organ. This is an important first step towards the goal of generating a clinically useful artificial thymus in the lab."

The thymus is the central hub of the immune system sending out infection fighting T-cells.

People with a defective thymus lack functioning T-cells and are highly vulnerable to infections. This is especially hazardous for bone marrow transplant patients, who need a working thymus to rebuild their immune systems after surgery.

Around one in 4,000 babies born each year in the UK have a malfunctioning or completely absent thymus, due to rare conditions such as DiGeorge syndrome.

Thymus disorders can be treated with infusions of extra immune cells or transplantation of a new organ soon after birth. However, such approaches are severely limited by a lack of donors and tissue rejection.

The new research, published in the journal Nature Cell Biology, raises the possibility of creating a whole new functioning thymus using cells manufactured in the laboratory.

While fragments of organs, including hearts, livers and even brains, have been grown from stem cells, no one before has succeeded in producing a fully intact organ from cells created outside the body.

Dr Rob Buckle, head of regenerative medicine at the MRC, said: "Growing 'replacement parts' for damaged tissue could remove the need to transplant whole organs from one person to another, which has many drawbacks not least a critical lack of donors.

"This research is an exciting early step towards that goal, and a convincing demonstration of the potential power of direct reprogramming technology, by which once cell type is converted to another. However, much more work will be needed before this process can be reproduced in the lab environment, and in a safe and tightly controlled way suitable for use in humans."

Chris Mason, Professor of Regenerative Medicine at University College London, said: "Using living cells as therapies has the big advantage in that the functionality of cells is many orders of magnitude greater than that of conventional drugs. Nowhere is this level of functionality more needed than in curing disorders of the immune system.

British scientists create first complete working organ from cells

British scientists produced a working thymus, a vital immune system "nerve centre" located near the heart.

In future the technique, so far only tested on mice, could be used to provide replacement organs for people with weakened immune systems, scientists believe.

But it might be another 10 years before such a treatment is shown to be effective and safe enough for human patients.

The research by-passed the usual step of generating "blank slate" stem cells from which chosen cell types are derived.

Instead, connective tissue cells from a mouse embryo were converted directly into a completely different cell strain by flipping a genetic "switch" in their DNA.

The resulting thymic epithelial cells (TECs) were mixed with other thymus cell types and transplanted into mice, where they spontaneously organised themselves and grew into a whole structured organ.

Professor Clare Blackburn, from the Medical Research Council (MRC) Centre for Regenerative Medicine at the University of Edinburgh, who led the team of scientists, said: "The ability to grow replacement organs from cells in the lab is one of the 'holy grails' in regenerative medicine. But the size and complexity of lab-grown organs has so far been limited.

"By directly reprogramming cells we've managed to produce an artificial cell type that, when transplanted, can form a fully organised and functional organ. This is an important first step towards the goal of generating a clinically useful artificial thymus in the lab."

If the immune system can be compared with an army, the thymus acts as its operations base. Here, T-cells made in the bone marrow are primed to attack foreign invaders, just as soldiers are armed and briefed before going into battle.

Once deployed by the thymus, the T-cells protect the body by scanning for infectious invaders such as bacteria and viruses, or dangerous malfunctioning cells, for instance from tumours. When an "enemy" is detected, the T-cells mount a co-ordinated immune response that aims to eliminate it.

First intact organ built from cells created in lab

An Australian-based biomedical company has been given approval from the AFL to use stem-cell therapy on players recovering from injury.

Sydney-based Regeneus has revealed it was recently given permission for its HiQCell treatment on players suffering from such issues as osteoarthritis and tendinopathy.

The treatment is banned by the World Anti-Doping Agency if it is performance-enhancing but allowed if it is solely to treat injuries.

Regeneus commercial development director Steven Barberasaid the regenerative medicine company had sought approval from the AFL for what the company says is "innovative but not experimental" treatment.

"In 2013, Regeneus sought and received clearance from ASADA [Australian Sports Anti-Doping Authority] for its proprietary HiQCell therapy for use with athletes who participate in sporting competitions subject to the WADA Anti-Doping Code. The AFL is one of many professional sports bodies which applies the WADA Anti-Doping Code within its regulations for players," he said.

"In March this year, the AFL introduced a Prohibited Treatments List as an additional level of scrutiny over and above the WADA code for player treatments. In light of this, Regeneus made a submission to the AFL to confirm that our specific treatment is not prohibited under that list. Subsequently, the chief medical officer of the AFL has recently communicated with our primary Melbourne-based HiQCell medical practitioner that the treatment is not prohibited and can be administered on a case-by-case basis to players.

"We anticipate documented confirmation of this outcome in the near future from the AFL.

"To our knowledge, the permission is specific to HiQCell and not necessarily to cell-based therapies in general."
