A LITTLE stress is all it took to make new life from old. Adult cells have been given the potential to turn into any type of body tissue just by tweaking their environment. This simple change alone promises to revolutionise stem cell medicine.

Yet New Scientist has also learned that this technique may have already been used to make a clone. "The implication is that you can very easily, from a drop of blood and simple techniques, create a perfect identical twin," says Charles Vacanti at Harvard Medical School, co-leader of the team involved.

Details were still emerging as New Scientist went to press, but the principles of the new technique were outlined in mice in work published this week. The implications are huge, and have far-reaching applications in regenerative medicine, cancer treatment and human cloning.

In the first few days after conception, an embryo consists of a bundle of cells that are pluripotent, which means they can develop into all cell types in the body. These embryonic stem cells have great potential for replacing tissue that is damaged or diseased but, as their use involves destroying an embryo, they have sparked much controversy.

To avoid this, in 2006 Shinya Yamanaka at Kyoto University, Japan, and colleagues worked out how to reprogram adult human cells into what they called induced pluripotent stem cells (iPSCs). They did this by introducing four genes that are normally found in pluripotent cells, using a harmless virus.

The breakthrough was hailed as a milestone of regenerative medicine the ability to produce any cell type without destroying a human embryo. It won Yamanaka and his colleague John Gurdon at the University of Cambridge a Nobel prize in 2012. But turning these stem cells into therapies has been slow because there is a risk that the new genes can switch on others that cause cancer.

Now, Vacanti, along with Haruko Obokata at the Riken Center for Developmental Biology in Kobe, Japan, and colleagues have discovered a different way to rewind adult cells without touching the DNA. The method is striking for its simplicity: all you need to do is place the cells in a stressful situation, such as an acidic environment.

The idea that this might work comes from a phenomenon seen in the plant kingdom, whereby drastic environmental stress can change an ordinary cell into an immature one from which a whole new plant can arise. For example, the presence of a specific hormone has been shown to transform a single adult carrot cell into a new plant. Some adult cells in reptiles and birds are also known to have the ability to do this.

Stem cell power unleashed after 30 minute dip in acid

Wednesday 29 January 2014 14.05

A "revolutionary" new approach to creating stem cells in the laboratory could open up a new era of personalised medicine, it is claimed.

Scientists have shown it is possible to reprogramme cells into an embryonic-like state simply by altering their environment.

It means in principle that cells can have their developmental clock turned back without directly interfering with their genes - something never achieved before.

The cells become "pluripotent", having the potential ability to transform themselves into virtually any kind of tissue in the body, from brain to bone.

Reprogramming a patient's own cells in this way is seen as the Holy Grail of regenerative medicine.

It raisesthe prospect of repairing diseased and damaged organs with new healthy tissue that will not be rejected by the immune system.

Current methods of performing the same trick involve genetic manipulation, which carries with it a serious risk of triggering cancer.

But the new method described in the journal Nature requires no genetic tweaking.

Scientists simply bathed immature white blood cells from mice in an acidic solution for 25 minutes.

TUESDAY, Jan. 28, 2014 (HealthDay News) -- Scientists might be able to offer "hair-challenged" males a new glimmer of hope when it comes to reversing baldness.

Researchers from the University of Pennsylvania say they've gotten closer to being able to use stem cells to treat thinning hair -- at least in mice.

The researchers said that although using stem cells to regenerate missing or dying hair follicles is considered a potential way to reverse hair loss, it hasn't been possible to create adequate numbers of hair-follicle-generating stem cells -- specifically cells of the epithelium, the name for tissues covering the surface of the body.

But new findings indicate that this may now be achievable.

"This is the first time anyone has made scalable amounts of epithelial stem cells that are capable of generating the epithelial component of hair follicles," Dr. Xiaowei Xu, an associate professor of dermatology at Penn's Perelman School of Medicine, said in a university news release.

Those cells have many potential applications that extend to wound healing, cosmetics and hair regeneration, Xu said.

In the new study, Xu's team converted induced pluripotent stem cells (iPSCs) -- reprogrammed adult stem cells with many of the characteristics of embryonic stem cells -- into epithelial stem cells. This is the first time this has been done in either mice or people, the researchers said.

The epithelial stem cells were mixed with certain other cells and implanted into mice. They produced the outermost layers of skin cells and follicles that are similar to human hair follicles, according to the study, which was published Jan. 28 in the journal Nature Communications. This suggests that these cells might eventually help regenerate hair in people, the researchers said.

The human body is daily exposed to external assaults such as bacteria, ultraviolet light or chemical agents. Skin, the largest organ of the body, is the first line of defense against these agents. Skin performs this function thanks to the close connections established between its cells (e.g. adherens junctions). The loss of cell adhesion between these cells is related to inflammatory diseases and cancer, hence the special interest in this area of research over the past years.

A study by the Spanish National Cancer Research Centre (CNIO), featured on the cover of the Journal of Cell Biology, shows how interactions between skin stem cellsthe cells responsible for the constant renewal of skinmaintain the architecture of this organ. "We knew that these junctions were important in skin stem cells but the cellular components involved in their structure and function were not yet understood", says Mirna Prez-Moreno, head of the Epithelial Cellular Biology Group that led the study.

Using skin cells derived from mice, researchers have discovered that one of the key elements in the formation and stabilisation of these junctions are microtubules, tubular structures that are part of all cells and that serve as pillars to maintain their form and function.

"We have seen for the first time that skin stem-cell microtubules connect with cell-cell junctions to form velcro-like structures that hold the cells together", says Marta Shahbazi, a researcher on Prez-Moreno's team and the first author of the study.

The connection between these two cellular componentsmicrotubules and cell-cell junctionsoccurs via the interaction between the CLASP2 and p120 catenin proteins, linked to microtubules and cell junctions respectively.

"We found that the abscence of CLASP2 or p120 catenin in epidermal stem cells caused a loss of their adhesion, and therefore the structure of these cells", says Shahbazi.

"Our results will open up new paths for exploring how these proteins regulate skin physiology", says Prez-Moreno, adding that this knowledge will be "important for the possible development of future regenerative or anti cancer therapies".

CHICAGO The International Society for Stem Cell Research (ISSCR) has announced the following 2014 award recipients, who will be formally recognized at its 12th Annual Meeting in Vancouver, taking place June 18-21, 2014:

The McEwen Award for Innovation, supported by the McEwen Centre for Regenerative Medicine, recognizes original thinking and groundbreaking research pertaining to stem cells or regenerative medicine that opens new avenues of exploration toward the understanding or treatment of human disease or affliction. The winner receives $100,000 USD. Past winners include James Thomson, Rudolf Jaenisch, Kazutoshi Takahashi and Shinya Yamanaka.

Award recipient Surani is a world leader in the field of epigenetics and the development of the mammalian germ line. His work on early mammalian development led to his involvement in the discovery of genomic imprinting and ongoing contributions to understanding the mechanistic basis of imprinting. Most relevant to stem cell biology, is his work on the cellular and molecular specification of the mammalian germ cell lineage, which impacted the field's understanding of how the germ line is established and the molecular mechanisms responsible for reprogramming the epigenome in order to generate the totipotent state.

"The ISSCR is thrilled to announce the McEwen Award for Innovation, our most prestigious award, will be presented to Azim Surani," Janet Rossant, ISSCR president, said. "His pioneering research, which has changed the face of epigenetics and advanced the field of stem cell biology, is a rare and significant contribution from a single individual."

The ISSCR-BD Biosciences Outstanding Young Investigator Award recognizes exceptional achievements by an ISSCR member and investigator in the early part of their independent career in stem cell research. The winner receives a $7,500 USD personal award and an opportunity to present at the ISSCR Annual Meeting. Past winners include Marius Wernig, Cdric Blanpain, Robert Blelloch, Joanna Wysocka and Konrad Hochedlinger.

Award recipient Greco established a noninvasive method to directly visualize skin stem cell division in real time in living animals the first of its kind for imaging any stem cell. By combining this method with laser ablation and transgenic lineage tracing, she captured previously inaccessible key information on stem cell behavior during tissue maintenance and regeneration. She demonstrated that the niche location of stem cells dictates their fates, the niche is required for tissue maintenance, and that a -catenin-mediated extrinsic mechanism regulates stem cell activation.

"The ISSCR is looking forward to presenting our Outstanding Young Investigator Award to Valentina Greco," Rossant said. "Her enthusiastic nomination by over a dozen leaders in the field of stem cell research demonstrates the significance of her early-career contributions to stem cell biology and regenerative medicine."

A team of engineers at the University of Wisconsin-Madison has created a process to improve the creation of synthetic neural stem cells for use in central nervous system research.

The process, outlined in a paper published in Stem Cells last month, will improve the state of the art in the creation of synthetic neural stem cells for use in central nervous system research.

Randolph Ashton

Human pluripotent stem cells have been used to reproduce nervous-system cells for use in the study and treatment of spinal cord injuries and of diseases such as Parkinson's and Huntington's.

Currently, most stem cells used in research have been cultured on mouse embryonic fibroblasts (MEFs), which require a high level of expertise to prepare. The expertise required has made scalability a problem, as there can be slight differences in the cells used from laboratory to laboratory, and the cells maintained on MEFs are also undesirable for clinical applications.

Removing the high level of required skill and thereby increasing the translatability of stem cell technology is one of the main reasons why Randolph Ashton, a UW-Madison assistant professor of biomedical engineering and co-author of the paper, wanted to create a new protocol.

Rather than culturing stem cells on MEFs, the new process uses two simple chemical cocktails to accomplish the same task. The first mixture, developed by John D. MacArthur Professor of Medicine James Thomson in the Morgridge Institute for Research, is used to maintain the stem cells in the absence of MEFs. The second cocktail allows researchers to push the stem cells toward a neural fate with very high efficiency.

These chemical mixtures help to ensure the consistency of the entire process and give researchers a better understanding of what is driving the differentiation of the cells. "Once you remove some of the confounding factors, you have better control and more freedom and flexibility in terms of pushing the neural stem cells into what you want them to become," says Ashton.

Sugar Land orthopedic surgeon Dr. Mark Maffet of Houston Methodist Orthopedics & Sports Medicine is the first orthopedic surgeon in Fort Bend County who is using stem cells to help accelerate healing and recovery after surgery.

Stem cells hold a great deal of promise in orthopedics, Dr. Maffet said. Right now, their use is cutting edge but I believe they will ultimately play a huge role in making surgical repair more successful.

Stem cells are found in bone marrow, blood and various types of tissue. Because they can differentiate into specialized cells and continuously divide, stem cells act as a repair system for the body and can replenish damaged tissue.

Dr. Maffet used stem cells to surgically repair Amy Statlers ACL tear. ACL tears are a common sports injury that often requires reconstruction of the knee.Statleris an active woman who enjoys playing softball and exercising and wanted to get back to her active lifestyle quickly.

Dr. Maffet made me feel comfortable by explaining the process and answering all of my questions about the surgery;it was important for me to have a quick recovery,"Statlerexplained."I am currently in physical therapy and am expected to be back on the softball field for our first practice in February. I am so happy with my recovery thus far and I feel better every day.

During ACL reconstruction surgery, orthopedic surgeons take a tendon from the knee or hamstring (either a patient's own or from a donor) and use it to replace the damaged ACL ligament. Dr. Maffet has begun using stem cells to help the body accept the new tendon and to speed the healing process.

The new ACL graft is soaked in a concentrate full of stem cells and other growth factors prior to fixation, he explained. In other cases, we can simply suture the torn ligament and inject the stem cell concentrate into the affected area.

Dr. Maffet is also using stem cells in rotator cuff repairs of the shoulder. By creating vascular channels down into the bone at the repair site, his goal is to trigger the stem cells located there and improve tendon healing. Other physicians throughout Houston Methodist, including Dr. David Lintner in the Medical Center, are also offering this procedure.

In time, I believe we will be able to show that the use of stem cells in orthopedic applications is making a difference in the lives of our patients, he said. The potential to repair and regenerate damaged tissue or bone, using the patients own stem cells, will give us a fantastic new tool in treating sports injuries and other orthopedic issues. The ability to make our patients recoveries easier and more successful is exciting.

Sugar Land surgeon becomes first in Fort Bend to use stem cells in orthopedic surgery

Researchers have developed a new way to study bone disorders and bone growth, using stem cells from patients afflicted with a rare, genetic bone disease. The approach, based on Nobel-Prize winning techniques, could illuminate the illness, in which muscles and tendons progressively turn into bone, and addresses the similar destructive process that afflicts a growing number of veterans who have suffered blast injuries including traumatic amputations or injuries to the brain and nervous system. This insidious hardening of tissues also grips some patients following joint replacement or severe bone injuries.

The disease model, described in a new study by a UC San Francisco-led team, involves taking skin cells from patients with the bone disease, reprogramming them in a lab dish to their embryonic state, and deriving stem cells from them.

Edward Hsiao, MD, PhD

Once the team derived the stem cells, they identified a cellular mechanism that drives abnormal bone growth in the thus-far untreatable bone disease, calledfibrodysplasiaossificansprogressiva(FOP). Furthermore, they found that certain chemicals could slow abnormal bone growth in the stem cells, a discovery that might help guide future drug development.

Clinically, the genetic and trauma-caused conditions are very similar, with bone formation in muscle leading to pain and restricted movement, according to the leader of the new study, Edward Hsiao, MD, PhD, an endocrinologist who cares for patients with rare and unusual bone diseases at the UCSF Metabolic Bone Clinic in the Division of Endocrinology and Metabolism.

The human cell-based disease model is expected to lead to a better understanding of these disorders and other illnesses, Hsiao said.

The new FOP model already has shed light on the disease process in FOP by showing that the mutated gene can affect different steps of bone formation, Hsiao said. These different stages represent potential targets for limiting or stopping the progression of the disease, and may also be useful for blocking abnormal bone formation in other conditions besides FOP. The human stem-cell lines we developed will be useful for identifying drugs that target the bone-formation process in humans."

The teams development of, and experimentation with, the human stem-cell disease model for FOP, published in the December issue of theOrphanetJournal of Rare Diseases, is a realization of the promise of research using stem cells of the type known as induced pluripotent stem (iPS) cells, immortal cells of nearly limitless potential, derived not from embryos, but from adult tissues.

Shinya Yamanaka, MD, PhD, a UCSF professor of anatomy and a senior investigator with the UCSF-affiliated Gladstone Institutes, as well as the director of the Center foriPSCell Research and Application (CiRA) and a principal investigator at Kyoto University, shared the Nobel Prize in 2012 for discovering how to makeiPScells from skin cells using a handful of protein factors. These factors guide a reprogramming process that reverts the cells to an embryonic state, in which they have the potential to become virtually any type of cell.

Regenocyte Adult Stem Cell Therapy-Neim Malo

BERLIN, Jan. 3 (Xinhua) -German scientists have developed a prototype of artificial bone marrow, which can simplify the treatment of leukemia in a few years, Karlsruhe Institute of Technology (KIT) announced on Friday.

Scientists from KIT, Max Planck Institute for Intelligent Systems in Stuttgart and the University of Tubingen have recreated basic properties of the natural bone marrow artificially in a laboratory.

The haematopoietic stem cells provide replenishment of red blood cells or immune cells, so they can be used for the treatment of leukemia, in a way that the diseased cells of the patient are replaced with healthy haematopoietic stem cells from a matched donor.

However, at present not every leukemia patient can find a matchable doner, so a simple solution to this problem would be to increase hematopoietic stem cells.

As the hematopoietic stem cells retain their stem cell properties only in their natural environment, the scientists need to create an environment that resembles the stem cell niche in the bone marrow.

To accomplish this goal, the German scientists created with synthetic polymer a porous structure that mimics the structure of the spongy bone in the area of the hematopoietic bone marrow.

In the artificial bone marrow, the researchers directed isolated hematopoietic stem cells freshly from umbilical cord blood and incubated them for several days.

Analyzes with different methods showed that the cells actually proliferate in the newly developed artificial bone marrow.

Now the scientists can study the interactions between materials and stem cells in detail in the laboratory to find out how the behavior of stem cell is influenced and controlled by synthetic materials.

This knowledge could help to realize an artificial stem cell niche for the targeted increase of stem cells to treat leukemia patients in 10 to 15 years.

(This is my blog post about the embryonic stem cell study. For my news article about the study, go here.)

Genetically modified human embryonic stem cells can solve one of the toughest problems facing embryonic stem cell therapy, immune rejection of transplanted cells, may have been solved, according to a UC San Diego-led research team.

The cells can be made invisible to the immune system by genetically modifying them to make two immune-suppressing chemicals, according to a study performed in mice given a human immune system. Immune functioning in the rest of the animal remains active. The immune protection also applies to differentiated cells derived from the stem cells.

If the approach works in people, patients receiving transplanted tissue or organs made from embryonic stem cells wouldn't have to take harsh immune-suppressing drugs, said Yang Xu, a UCSD professor of biology. The method also may prevent immune rejection of tissues grown from other types of stem cells.

These arehumanized laboratory mice that contain a functional human immune system. Such mice have been used for years; a UCSD research team developed a model with a stronger immune response to test their immune-suppressing tissues. / Zhili Rong, UCSD

Researchers placed genes in the stem cells to produce the two chemicals, CTLA4-lg and PD-L1, naturally made in the body. The humanized immune systems of the mice accepted transplants of cells engineered to make the chemicals. The researchers transplanted cardiomyocytes and fibroblasts derived from the engineered stem cells. Transplants derived from regular embryonic stem cells were rejected.

The study was published online Thursday in the journal Cell Stem Cell. Its findings will have to be confirmed for safety and effectiveness in more animal studies before human trials can be considered, which will take years. The mouse model itself was "optimized" for the study to more faithfully reflect the human immune system than other immune models, the study said.

Xu said a further study is being considered in monkeys, a large animal model considered to better reflect human biology than mice.

Embryonic stem cells are being tested along with many other kinds of stem cells to replace diseased or destroyed body parts, such as spinal cord segments and insulin-producing beta cells in the pancreas. All of these cells have advantages and drawbacks. Immune rejection, along with a tendency to form tumors, are two big drawbacks to embryonic stem cells.

San Diego-based ViaCyte is preparing to test a therapy with beta cells within a year. The company encapsulates them in a permeable barrier that allows insulin to diffuse out but prevents the immune system from entering. However, that approach won't worth with transplants that must integrate into the body, such as spinal cord tissue. So a way of turning off the immune system just in those cells is an attractive idea.

An artists impression of the European Space Agencys Rosetta probe, which aims to be the first to land on a comet.

Several research groups, including a team led by geneticist Erika Sasaki and stem-cell biologist Hideyuki Okano at Keio University in Tokyo, hope to create transgenic primates with immune-system deficiencies or brain disorders. This could raise ethical concerns, but might bring us closer to therapies that are relevant to humans (mice can be poor models for such disorders). The work will probably make use of a gene-editing method called CRISPR, which saw rapid take-up last year.

The European Space Agencys Rosetta spacecraft could become the first mission to land a probe on a comet. If all goes well, it will land on comet ChuryumovGerasimenko in November. Mars will also be a busy place: Indias orbiter mission should arrive at the planet in September, about the same time as NASAs MAVEN probe. And NASAs Curiosity rover should finally make it to its mission goal, the slopes of the 5.5-kilometre-high Aeolis Mons, where it will look for evidence of water. Back on Earth, NASA hopes to launch an orbiter to monitor atmospheric carbon dioxide.

Neurobiologist Miguel Nicolelis at Duke University in Durham, North Carolina, has developed a brain-controlled exoskeleton that he expects will enable a person with a spinal-cord injury to kick the first ball at the 2014 football World Cup in Brazil. Meanwhile, attempts are being made in people with paralysis to reconnect their brains directly to paralysed areas, rather than to robotic arms or exoskeletons. In basic research, neuroscientists are excited about money from big US and European brain initiatives, such as Europes Human Brain Project.

In the pharmaceutical industry, all eyes are on trial results from two competing antibody treatments that harness patients immune systems to fight cancer. The drugs, nivolumab and lambrolizumab, work by blocking proteins that prevent a persons Tcells from attacking tumours. In early tests, the drugs evoked a better level of response in patients than ipilimumab, a similar therapy that was launched in 2011 to treat advanced melanoma.

Semiconductors known as perovskites convert light energy into electricity. They are cheap to build and have already shown conversion rates of more than 15% (a leap from 4% when the feat was first reported in 2009). Expect to see still-higher efficiencies this year, perhaps reaching 20% the same as the lower end of existing commercial silicon-based photo-voltaics. A team at the University of Oxford, UK, also hopes to make lead-free perovskites.

In 2013, two research teams showed that broadly neutralizing antibodies that target an array of HIV types quickly cleared an HIV-related virus in monkeys. The therapy will be tested in people who carry HIV, with results expected in the autumn. Meanwhile, last years curing of a baby born with the virus might lead to wider trials of the technique used: high doses of antiretroviral drugs given at birth.

Technology that rapidly sequences DNA as it is fed through a ring of proteins, known as a biological nanopore, will hit the market this year after decades of development. Oxford Nano-pore Technologies in Oxford, UK, aims to release the first data from a disposable sequencer the size of a memory stick, which it is sending to scientists for testing. It promises to read longer strands of DNA than other techniques (potentially useful in sequencing mixed samples of bacterial DNA, for example), and to show results in real time.

The Intergovernmental Panel on Climate Change will complete its fifth assessment report by November. The findings of working groups II and III will focus on the impacts of climate change, and on how societies can adapt to or mitigate those effects (working groupI published its findings last year). Away from formal negotiations, United Nations secretary-general Ban Ki-moon is hoping for bold pledges on emissions at a summit in New York in September. In research, a large carbon capture and storage project in Canada the Can$1.24-billion (US$1.17-billion) Boundary Dam coal power-plant in Saskatchewan begins commercial operation in April.

The complex world of Stephen Davies, PhD, is populated by nerve cells and fibers, star-shaped cells, precursor cells, and proteins. But the work he does with it all has one simple goal: to give hope to the victims of spinal cord injuries, and, ultimately, a wide array of neurological disorders that cause misery and exact an enormous individual and societal price.

Davies lab in Research Complex 1 on the Anschutz Medical Campus has attracted attention throughout the worldwide medical research community.

Stephen Davies, PhD

Davies is pushing forward with promising treatments hes developed that use stem cells to regenerate nerve growth in injured spinal cords. The approach has helped laboratory mice with spinal cord injuries (or SCIs) regain their mobility. He hopes to bring the treatments to clinical trial and, one day, mainstream medicine.

Im optimistic well have therapies for both acute and chronic injuries in the future, he says. Hopefully sooner rather than later.

The scar tissue that results from SCIs is the primary target of Davies work.

Davies found that treating animals with SCIs with a protein called decorin not only suppressed formation of molecules responsible for producing scarring, but also stimulated the growth of neurons (nerve cells) and axons, the long nerve cell fibers that conduct electrical impulses between the spinal cord and the brain.

Decorin overrides the inhibitors to new nerve growth and allows new communications to be made," Davies explains. He says new neuron and axon growth in laboratory mice with decorin increased at 15 times the rate of untreated mice.

The therapies were working on have an obvious application for the treatment of wounded warriors coming home from the Middle East," Davies says. There are terrible neurologic problems being accrued on the battlefield and from [improvised explosive devices].

He believes his research could ultimately lead to treatments for far more than spinal cord injuries. Its a technical approach to general repair of the central nervous system, he asserts. It could be developed for use in stroke, traumatic brain injuries and a variety of neurologic disorders. And it could prove effective at preventing atrophy of damaged brain neurons and protecting them from dying. That advance would offer hope to Alzheimers patients.

Orange County, California (PRWEB) December 23, 2013

The top stem cell therapy clinic in California, TeleHealth, is now offering PRP therapy for hip arthritis. The treatments are often able to delay or avoid the need for joint replacement, and are administered by Board Certified doctors at two clinic locations. Call (888) 828-4575 for more information and scheduling.

Tens of millions of Americans suffer from hip arthritis, and hundreds of thousands of hip replacements are performed every year. Nonoperative treatments prior to joint replacement often consist of steroid injections for pain relief. While the joint replacement typically has excellent pain relief outcomes, there are risks involved and sometimes the eventual need for a revision procedure.

Therefore, a procedure that offers pain relief while offering the potential for joint repair is a welcome option in hip arthritis management. TeleHealth is now offering platelet rich plasma therapy, known as PRP therapy for short, to provide pain relief and potential joint regeneration. The procedure involves a simple blood draw at the office, with the blood then being spun down in a centrifuge to obtain a solution of concentrated platelets and growth factors.

The PRP is then injected into the symptomatic hip, providing an immense amount of regenerative medicine to the arthritic joint. The material then calls in the body's stem cells as well. Published studies on PRP for joint arthritis have so far shown excellent results for pain relief.

Often times, PRP therapy at TeleHealth is covered by insurance. Verification by the clinic is able to check prior to the procedure. Patients are seen from all over Southern California for treatment of hip, knee and shoulder arthritis along with tendonitis and ligament injury. This often includes athletes, weekend warriors, executives, senior citizens and more.

To receive further information on stem cell and PRP therapy for joint arthritis or soft tissue injury, call (888) 828-4575.

It's the Christmas gift one little boys family thought they would never receive a life-saving transplant after a worldwide search for a donor.

But miraculously, two-year-old Gaurav Bains has finally had the operation he desperately needed.

His family have endured a torturous ordeal as the months counted down to a Christmas deadline to find a bone marrow donor with a 100 per cent match.

The young lad had always been ill after being born premature, but earlier this year, after a series of chest infections, he was diagnosed with Monosomy 7 Syndrome, a rare blood condition.

Then in the summer, his family was told his best chance of a healthy life would be if a donor was found before Christmas

Had a match not been found, Gauravs condition meant he would have been likely to develop an aggressive form of childhood leukaemia, which he may not have survived.

But thanks to a huge campaign, and the determination of his family, thousands of people signed up to the donation register from around the country and the world.

And this week the youngster finally had the operation that could save his life.

The whole procedure, which saw donated stem cells passed into his body, only took 90 minutes, and now his family, from Alexandra Road in Tipton, are optimistic.

Dad Sunny Bains, aged 31 and a shopkeeper, said: Everything went alright and he didnt have any side effects.

Abba Zubair, medical and scientific director of the Cell Therapy Laboratory at the Mayo Clinic in Jacksonville, wants to test the feasibility of growing stem cells in outer space, cells that could be used to generate new tissue and even new organs in human beings.

There are reasons to believe that stem cells, which are hard to grow in the great quantity they are needed on Earth, will grow much more rapidly in the microgravity environment in space, Zubair thinks. Now the Center for the Advancement in Science in Space has given Zubair a $300,000 grant to test that by placing stem cells in a specialized cell bioreactor in the International Space Station.

It now takes a month to generate enough cells for a few patients, Zubair said. A clinical laboratory in space could provide the answer we all have been seeking for regenerative medicine. ... If you have a ready supply of these cells, you can treat almost any condition and can theoretically regenerate entire organs using a scaffold. Additionally, they dont need to come from individual patients. Anyone can use them without rejection.

The stem cells he plans to grow in space will be stem cells that can induce regeneration of neurons and blood vessels in patients who have suffered hemorrhagic strokes caused by blood clots.

I have a special personal interest in stroke, Zubair said. Thats what killed my mom years ago. I really would like to conquer and treat stroke.

The first step in growing stem cells in space is happening at the University of Colorado where engineers are building the cell bioreactor Zubair will use on the space station. Within a year, Zubair hopes to transport the bioreactor and stem cells to the space station, perhaps aboard a flight by SpaceX, a company expected to begin commercial flights to the space station soon.

Once the bioreactor and stem cells are aboard the space station, it will take about a month to grow them, Zubair said. The results will then be analyzed by the astronauts on the space station and by researches back in Zubairs Jacksonville laboratories.

We will be trying to determine if our notion that stem cells grow faster in microgravity is true, Zubair said. We also want to know how feasible it is to produce clinical grade cells in space that can be used in humans.

Hes optimistic his study will show that growing stem cells in space is a viable way to create stem cells in quantity.

Were quite excited, he said. I really think the future is full of promise. We just have to take the opportunity to make that a reality.

The breakthrough marks a major advance in treating kidney disease and more avenues in bioengineering human organs. Researchers published their findings in the journal Nature Cell Biology, following their success in making human skin cells form a functioning "mini-kidney" with a width of only a few millimeters.

During self-organization, different types of cells arrange themselves with respect to each other to create the complex structures that exist within an organ, in this case, the kidney, Professor Melissa Little of University of Queenslands Institute for Molecular Bioscience (IMB), who led the study, said in a statement. The fact that such stem cell populations can undergo self-organization in the laboratory bodes well for the future of tissue bioengineering to replace damaged and diseased organs and tissues.

While it may be a while until the process can be used in human trials, Little says it could be a major development in treating chronic kidney disease.

One in three Australians is at risk of developing chronic kidney disease, and the only therapies currently available are kidney transplant and dialysis, Little said. Only one in four patients will receive a donated organ, and dialysis is an ongoing and restrictive treatment regime.

The engineered kidney is a first for science.

"This is the first time anybody has managed to direct stem cells into the functional units of a kidney," Professor Brandon Wainwright, from the University of Queensland, told The Telegraph. "It is an amazing process it is like a Lego building that puts itself together."

Scientists were able to make the kidney by identifying genes that remained active and inactive during kidney development. They were then able to alter the genes into embryonic cells that allowed them to self-organize into the human organ.

"The [researchers] spent years looking at what happens if you turn this gene off and this one on," Wainwright said. "You can eventually coax these stem cells through a journey they [the cells] go through various stages and then think about being a kidney cell and eventually pop together to form a little piece of kidney."

Little predicts the stem cell kidneys could one day be used to make human kidney transplants, or a cluster of mini kidneys used to boost renal function in patients.
