Asterias was created by BioTime to acquire Geron Corporations clinical-stage stem cell therapeutic assets. The companys work centers on the development of therapeutics derived from stem cells capable of becoming all of the cell types in the human body to fight disease, a process known as pluripotency. Together, Asterias and BioTime have the largest intellectual property portfolio of any company in the pluripotent stem cell field with over 600 patents and patent applications worldwide covering key therapeutic targets derived from each of the three primary germ layers that give rise to all cells in the human body. Asterias lead clinical programs are its AST-OPC1 cell therapeutic for spinal cord injury, which recently received clinical trial funding support through an award of $14.3 million by the California Institute for Regenerative Medicine (CIRM), and its AST-VAC2 allogeneic dendritic cell cancer immunotherapy platform.

"Pedro has the ideal mix of skills to lead Asterias in the next stage of its growth," said Michael D. West, Ph.D., BioTimes CEO. "His experience in shepherding medicines through clinical and regulatory processes to commercialization will be invaluable as Asterias moves forward with its plans to bring two of its product candidates into clinical trials. Pedro is also a seasoned business leader and manager whose long track record in building businesses and business alliances speaks for itself.

I am excited to be working with Asterias talented employees, whose hard work and incredible talent have been responsible for the rapid advancement of a number of promising treatments, said Mr. Lichtinger. The pluripotent stem cell technology platform is rapidly emerging into the clinic with a focus on major unmet medical needs that have limited or no cures available. Asterias two most advanced clinical programs have the potential to significantly improve patient outcomes and I am delighted to be a part of this effort.

Mr. Lichtinger has served as a director of BioTime since August 2009, during which time he has helped to guide its development as a leader in the field of regenerative medicine. Reflecting his new role at Asterias, Mr. Lichtinger has been nominated for election to the Asterias Board of Directors at the companys upcoming annual meeting, and will not stand for reelection to the BioTime Board of Directors at BioTimes upcoming annual meeting.

Since April, Dr. West, BioTimes longtime CEO, has also served as President and CEO of Asterias. With the appointment of Mr. Lichtinger as CEO, Dr. West will continue to be a member of the Board of Asterias and will resume his position as Vice President Technology Integration at Asterias, while continuing as BioTimes CEO.

Mr. Lichtinger has some 35 years of executive leadership experience in the pharmaceutical industry. Previously, he was president and CEO of Optimer Pharmaceuticals, a role that he held from May 2010 to February 2013. There, he led the successful registration and commercialization of DIFICID (fidaxomicin). Before joining Optimer, Mr. Lichtinger held a series of top management positions at Pfizer over a 25-year career, including serving as president of Pfizers Global Primary Care Unit, where he oversaw $23 billion in revenue and was responsible for a development budget in excess of $800 million including a portfolio of 66 projects. He also led Pfizers European operations as president of that group encompassing 27 countries and all Pfizer medicines, and previously headed Pfizers Global Animal Health business. In these roles, Mr. Lichtinger oversaw the successful development, commercialization, and alliances of numerous drugs.

About Asterias

Asterias Biotherapeutics (Asterias) is a biotechnology company focused on the emerging field of regenerative medicine. Asterias core technologies center on stem cells capable of becoming all of the cell types in the human body, a property called pluripotency. Asterias plans to develop therapies based on pluripotent stem cells to treat diseases or injuries in a variety of medical fields, with an initial focus on the therapeutic applications of oligodendrocyte progenitor cells (AST-OPC1) and antigen-presenting dendritic cells (AST-VAC1 and AST-VAC2) for the fields of neurology and oncology respectively. AST-OPC1 was tested for treatment of spinal cord injury in the worlds first Phase 1 clinical trial using human embryonic stem cell-derived cells. Asterias plans to seek FDA clearance to reinitiate clinical testing of AST-OPC1 in spinal cord injury this year, and is also evaluating its function in nonclinical models of multiple sclerosis and stroke. AST-VAC1 and AST-VAC2 are dendritic cell-based vaccines designed to immunize cancer patients against telomerase, a protein abnormally expressed in over 95% of human cancer types. AST-VAC2 differs from AST-VAC1 in that the dendritic cells presenting telomerase to the immune system are produced from human embryonic stem cells instead of being derived from human blood.

Newswise LOS ANGELES (June 17, 2014) Stem cell therapy for cardiovascular disease isnt a medical pipe dream its a reality today, although patients need to better understand the complex science behind these experimental treatments, according to the chief of Cardiology for the Cedars-Sinai Heart Institute.

In a 17-minute TEDxGrandForks talk now available on YouTube.com, Timothy D. Henry, MD, known for his innovative work in developing stem cell treatments for advanced heart disease patients, said he understands why so many are confused about the latest scientific findings.

Most people today get our information from sound bites, and the issues surrounding stem cells are too complex to be fully explained in a single catchy phrase, Henry said, adding, We have far too much controversy about stem cells and far too much hype.

Stem cell science has become a political dividing line with many opposing research into stem cells derived from human embryos, Henry said. However, he said, todays leading-edge clinical research focuses on stem cells derived from adults that can be scientifically programmed to become a specialized cell, such as a heart cell or a brain cell, thereby avoiding the ethical questions involved in embryonic research.

Very few of the cells we give actually become muscle or actually become blood vessels, Henry said. What they do is increase growth factors and encourage natural cells in the body to generate new, healthy tissue.

The Cedars-Sinai Heart Institute, directed by Eduardo Marbn, MD, PhD, is a world leader in studying the use of stem cells to regenerate heart muscle in patients who have had heart attacks. In 2009, Cedars-Sinai physicians conducted the first infusion of stem cells into heart attack patients, using stem cells grown from the patients own heart tissue. The resulting study, published in February 2012 in The Lancet, showed that patients who underwent the stem cell procedure experienced a significant reduction in the size of the scar left behind by a heart attack. Patients also experienced a sizable increase in healthy heart muscle following the experimental stem cell treatments.

Currently, Henry is co-directing a new stem cell study with Raj Makkar, MD, director of Interventional Cardiology. The national trial, called ALLSTAR, uses heart cells from unrelated donors in an effort to reverse lasting tissue damage after a heart attack.

During his talk, Henry also expressed concern for patients who might be taken advantage of by unscrupulous clinics outside of the United States that offer stem cell cures for everything from neurological diseases to baldness. Patients also need to understand that stem cell science has a long way to go before regenerative medicine treatments are widely available.

Stem Cell Expert Explains How Experimental Regenerative Medicine Therapies Can Regrow Damaged Heart Muscle

By Ian Dipple Wednesday 18 June 2014 Updated: 18/06 11:28

REDDITCH residents have been urged to join the bone marrow register to help the fight against blood cancer.

Anthony Nolan and Redditch MP Karen Lumley have joined forces for the appeal. For the first time the charity has mapped the bone marrow register across the UK by local area.

In Redditch there are more than 562 people willing to donate their stem cells or bone marrow to save the life of a stranger.

However it is well below the average of 796 per Parliamentary constituency and is ranked 467th out of 650.

Two thirds of UK patients in need of a transplant will not find a matching donor from their family. Anthony Nolan helps them find an unrelated donor but can currently only match half of all requests.

Mrs Lumley said: "I want to see many more of my constituents join this fight. Im hunting for more crusaders to sign up today, so we can fight blood cancer together. It is something truly heroic to give a stranger a second chance at life. This is why Im proud to champion this cause to my constituents."

Ann OLeary, head of register development at Anthony Nolan, added: "Donating is an incredibly selfless thing to do and will give someone with blood cancer their best chance at survival."

Anyone aged 16 to 30 and in good health can join the bone marrow register. It involves filling out a simple online form and spitting into a tube.

T cells use a novel mechanism to fight leukemia. They may recognize unique lipids produced by cancer cells and kill tumor cells expressing these lipid molecules. A study conducted by researchers at the University of Basel shows that a tumor-associated lipid stimulates specific T cells, which efficiently kill leukemia cells both in vitro and in animal models. The results have been published in the Journal of Experimental Medicine. Leukemias are cancer diseases affecting blood cells . Acute leukemias prevent development of normal bold cells and thereby are severe life-threatening diseases. Current therapy for acute leukemias is based on chemotherapy that eradicates tumor cells followed by bone-marrow stem cell transplantation that reconstitutes the patient with healthy blood cells. In some cases, leukemia cells survive this treatment and start to re-grow. A major aim of many studies is finding novel and efficient ways to detect and eradicate leukemia cells before a second outbreak of the disease.

More punch against tumor cells

T lymphocytes are major contributors to fight against leukemias. T cells may recognize and become activated by tumor-specific protein antigens in some instances produced in large amounts only by tumor cells. These protein antigens are also called tumor-associated antigens (TAA) and stimulate specific T cells, which in turn kill leukemia cells. However, protein TAA accumulation can be drastically reduced by variant leukemia cells and some TAA may change their structure, thus preventing recognition by T cells and facilitating tumor immune evasion.

Prof. Gennaro De Libero and his team from the Department of Biomedicine at the University of Basel has identified a new approach that might help to make the immune system more efficient in recognizing leukemia cells. His research team is studying T cells that specifically recognize lipid antigens since several years. Together with colleagues in Italy, China and Singapore, the Swiss team has identified a new lipid that accumulates in leukemia cells and that stimulates specific T cell responses. The new lipid methyl-lysophosphatidic acid (mLPA) is very abundant in several forms of human leukemias and is the first example of a lipid TAA.

The published study also shows that it is possible to isolate human T cells that specifically recognize and kill mLPA-expressing leukemia cells in in vitro tests. When these T cells were transplanted into mice, they also displayed great in vivo therapeutic efficacy against leukemia cells.

An important feature of mLPA is that differently from protein TAA, it does not change its structure, and remains abundant in leukemia cells. The Swiss team is now investigating, whether mLPA can be used to target leukemia cells in addition to protein TAA. This type of immunotherapy may be extremely beneficial in preventing relapses of the disease after chemotherapy and bone marrow transplantation. It opens new avenues to novel non-invasive cancer immunotherapies.

Lipids Help to Fight Leukemia

Phil Reyes, one of the Parkinson's patients in Summit 4 Stem Cell, urges California's stem cell agency to support its research.

A potentially groundbreaking trial to treat spinal cord injuries with tissue grown from human embryonic stem cells will resume, after being funded by the California's stem cell agency.

The California Institute for Regenerative Medicine's governing committee approved without opposition a $14.3 million award to Asterias Biotherapeutics of Menlo Park. Asterias is taking over from Geron, which stopped clinical trials in November, 2011. Geron, also of Menlo Park, said it discontinued the trials for business reasons. Asterias is a subsidiary of Alameda-based BioTime.

Patients will be given transplants of neural tissue grown from the embryonic stem cells. The hope is that the cells will repair the severed connections, restoring movement and sensation below the injury site.

CIRM also unanimously approved a $5.6 million grant for another potential breakthrough: a clinical trial by Sangamo Biosciences of Richmond, Calif, to cure HIV infection with gene therapy. The trial is now in Phase II. Immune cells are taken from the patient and given a mutant form of a gene that HIV uses to get inside the cells. The mutated gene resists infection. The genetically altered cells are then given back to the patient.

Approval of both grants had been expected, as staff reports had recommended their approval. The agency met in San Diego.

In addition CIRM's Independent Citizens Oversight Committee funded $16.2 million in grants to bring three stem cell researchers to California. That vote was more contentious, with some committee members arguing that it made no sense to bring more scientists to California without a specific need. In addition, they argued that CIRM's main emphasis needs to be on funding clinical trials.

Member Jeff Sheehy said that bringing the scientists to California doesn't create more scientific capacity. However, a vote to deny funding failed, and a subsequent vote to approve funding passed.

CIRM is projected to run out of its $3 billion in bond funding by 2017, and supporters of the public agency are considering asking California voters for more money.

Also appearing at the CIRM meeting were advocates of funding a stem cell-based therapy for Parkinson's disease. The therapy, which may be approved in 2015 for a clinical trial, uses artificial embryonic stem cells called induced pluripotent stem cells grown from the patient's own skin cells. The group, Summit 4 Stem Cell, plans to ask for funding to help with the trial in the near future.

An Okotoks boy may not understand his community is helping to give him a better life this weekend, but there is a good chance he will be smiling anyway.

At four years old, Ryker Menzies communicates through a series of sounds, suffers from frequent muscle spasms, is in a wheelchair because hes unable to walk or sit on his own and is constantly on painkillers.

This has been Rykers reality since infancy due to a severe case of cerebral palsy, and his parents Tiffany Boyd and Jamie Menzies are hopeful stem cell therapy treatment in Panama City will improve his muscle movement, vision and speech.

Unfortunately, they havent been able to afford the procedure living on one income while Boyd cares for Ryker.

To help pay for the $15,600 treatment, the couple is organizing a mini-market at the Foothills Centennial Centre on June 14 from 11 a.m. to 4 p.m. and inviting the community to check out an abundance of second-hand items and products from home-based and privately-owned businesses for an entry fee of $2.

Money will also be raised through a food vendor, numerous raffle tickets for prizes including vacations and toys, and items donated by residents. Okotoks singer Emily Gryba will perform at the event.

Ive been getting a lot of calls from people donating stuff to the market to sell there, as well as a few online donations, said Boyd. We will just set up about five tables and have family run them. The proceeds will go to Ryker.

Boyd said she is ecstatic at the amount of community support for Rykers stem cell treatment. An online fund she established called Raise for Rykstar collected $1,300, with another $2,000 donated by family, friends and community members.

The feedback has been fantastic, she said. Were already at $3,500.

As the family gets closer to reaching their financial goal, Boyd is eager to book an appointment to give Ryker the best life possible. She said she was told they will have an appointment within a month or two of making the call.

COLLEGE STATION - There are more than 18,000 people waiting for a bone marrow or stem cell transplant, something that could save their lives.

Despite the fact that there are 11-million people on the registry as available donors, only 40% of those in need will find a match.

That's because it's extremely difficult to match someone perfectly, and since it's done by DNA markers, the best chances come from someone in your same race and ethnicity group.

So while the odds are slim to begin with, the chance of finding a match for a minority is even smaller. Fewer minorities are signed up to be potential donors.

Lindsey Crawford, a local recruiter for the "Be the Match" foundation says, " African Americans make up about 10 percent of our registry, Hispanics about 6 percent and multi-racial only about 4 percent."

Most of the time, you won't have to actually donate bone marrow, it'll just be stem cells, which is a painless process similar to giving plasma. 20% of the time, actual bone marrow is needed, and that does require surgery, but you're given an anesthetic to ease the pain.

If you'd like to sign up to be a potential bone marrow or stem cell donor, you can visit http://www.bethematch.org.

Critical Need for Bone Marrow Donors

19 hours ago Fig. 1: Pluripotent stem cells enable planarians to achieve extraordinary feats of regeneration. (A) Planarians are able to re-grow an entire head in a matter of a few days. (B) The stem cells and their early offspring can be found almost all over the worms body.

Planarians are known as masters of regeneration: they can re-build any part of their bodies after amputation. This ability relies on a large number of pluripotent stem cells. To further investigate the mechanisms that enable planarians to maintain their stem cell pool over generations, scientists have now established a method for analysing the composition of planarian stem cells and the turnover of their proteins. They discovered a protein that is not only required for the maintenance of the stem cell pool in planarians, but might also be active in the pluripotent stem cells of mammals.

Of earthworms and flatworms

Everyone knows the myth about earthworms: if you cut them in half, you get two worms. Nothing could be further from the truth, alas. However, if the earthworm is replaced by a flatworm, the two parts can survive these childish experiments. What's more, be it skin, intestine or brain, the body part lost through cutting will simply grow again in a matter of days. The creatures involved here are planarians[1], a class of flatworms that are so flat that they need neither lungs nor a heart to take in and distribute oxygen in their bodies. So simple and yet so ingenious? It would appear so. Regeneration studies involving these animals have shown that a dismembered planarian can generate several hundred tiny animals, hence they could "almost be called immortal under the edge of a knife" (Dalyell, 1814). The astonishing aspect here is that both the blueprint and construction material for the regeneration process must be contained in each of the fragments: a small piece of tail, for example, becomes a complete worm under the animal's own strength and using existing resources.

Not the preserve of youth: pluripotency also available in adults

So where do the components needed to rebuild the cellular structures come from? In their search for the answer to this question, scientists have a population of small cells in their sights, namely the approximately five-micrometre-long neoblasts. These cells are found almost everywhere in the planarian body and behave like stem cells: they divide, renew and can form the different cell types that have been lost as a result of amputation (Fig. 1). When the planarian loses a body part or discards its tail for reproduction, the neoblasts are reactivated and migrate to the wound. They divide there and their offspring form a blastema, in which as a result of interplay between various extra- and intra-cellular factors important differentiation and patterning processes take place. Thanks to these processes, in turn, complex structures like the brain are formed. If the neoblasts are eliminated through radiation, for example, the planarian loses its ability to regenerate and dies within a few weeks. The fact that, following transplantation into an irradiated, neoblast-free worm, a single neoblast can produce all cell types and enable the host worm to regain its ability to regenerate shows that at least some neoblasts are pluripotent [2]. In healthy mammals, pluripotency, that is the ability of one cell to produce any given cell type found in an organism, e.g. muscle, nerve or pancreas cells, only arises in the early embryonic stage. Therefore, stable pluripotency in the adult organism is something special but not impossible as long as mechanisms exist for conserving this characteristic as is clearly the case with the planarians.

An in-vivo Petri dish for pluripotent stem cells

The preservation of pluripotency has been an important topic in stem cell research for years, and has mostly been examined up to now using isolated embryonic stem cells. Important transcription factors that can induce and preserve pluripotency were discovered in the course of this research. So what can planarians contribute to the current research if their stem cells cannot be cultivated and reproduced outside of the body? This is precisely where the strength of the planarians as a model system in stem cell research lies: the combination they can offer of a natural extracellular environment and pluripotent stem cells. Whereas cultivated stem cells are normally taken out of their natural environment and all important interactions with neighbouring cells and freely moving molecules are interrupted as a result, the stem cells in planarians can be observed and manipulated under normal conditions in vivo. Therefore, planarians are of interest as "in-vivo Petri dishes" for stem cells, in which not only their mechanisms for preserving pluripotency can be studied, but also their regulation and contribution to regeneration.

A venerable old worm meets ultra-modern next-generation technologies

Although planarians have been renowned as masters of regeneration and research objects for generations, they have undergone a genuine explosion in research interest in recent years. In particular, the possibility of switching off specific genes through RNA interference (RNAi) and the availability of the genome sequence of Schmidtea mediterranea, a planarian species which is especially good at regenerating itself, have contributed to this surge in interest. With the development of modern sequencing procedures, that is 'next generation sequencing', gene expression profiles that provide information about the specific genes activated in particular cells or tissues at particular points in time can now be produced on a large scale. Hence, it is possible to examine which messenger RNAs (mRNAs) are produced that act as molecular templates for the production of proteins. For example, hundreds of these mRNAs are produced after the amputation of a worm's head and their proteins provide potential regulators of the regeneration process [3; 4]. However, the real work only starts here: the extent to which the presence of a particular mRNA also reflects the volume of protein that is active in the cell remains to be determined. It is mainly the proteins in the form of enzymes, signalling molecules and structural elements, and not their mRNAs, that ultimately control the majority of cellular processes. In addition, their production using mRNA templates and their lifetime are precisely regulated processes and the frequency with which an mRNA arises cannot provide any information about these processes. The time has come, therefore, to develop experimental approaches for planarians that extend beyond gene expression analysis and lend greater significance to the subsequent regulatory processes.

Catherine M. Bollard, MBChB, MD, director of Childrens National Health Systems Program for Cell Enhancement and Technologies for Immunotherapy (CETI), and her team have performed the hospitals first treatment using T-cell therapy for a 6-month-old patient with congenital immune deficiency and a life-threatening virus infection.

Not only does this therapy offer a potentially curative treatment for patients who have failed conventional therapies for infections and cancer, the procedure sets the stage for avoiding potentially toxic drugs which can ultimately reduce inpatient stays and medical costs.

Its extremely important, offering a novel therapeutic thats not available at the majority of hospitals worldwide, said Dr. Bollard, a member of the Division of the Blood and Marrow Transplantation and senior scientist at Childrens Nationals Center for Cancer and Immunology Research at Childrens Research Institute. She is also the Principal Investigator and the Sheik Zayed Institute for Pediatric Surgical Innovation.

Childrens National is one of the few hospitals in the world to offer cellular therapy to treat life-threatening infections in patients with immune deficiencies as well as preventing or treating relapse in children with cancer. Cellular therapy uses the bodys own immune system to fight cancer and/or infections.

Patients from other hospitals and childrens facilities have been referred to Childrens National because of the uniqueness of the cell therapies we can now offer here, Dr. Bollard said. This kind of procedure reduces the amount of time for care and is not only cost effective for a hospital but also more tolerable for the patient, said Dr. Bollard. None of this could have been achieved without every one of those members within the CETI Program pulling together as a team to make it happen.

In the first of its kind cellular therapy achievement at Childrens National, Dr. Bollard and her team have shown that in the laboratory they can train nave or inexperienced immune system cells (T-cells) to kill cancer and/or viruses. In the first patient treated here, T-cells were grown from the patients mother and then injected into the young patient, who had severe combined immunodeficiency and a potentially life threatening virus infection. The T-cells the patient received (cytotoxic T lymphocytes) are a type of white blood cell that can kill virus-infected cells or cancer cells infected or cells that are damaged in other ways.

The babys immunodeficiency ailments included SCID, or severe combined immunodeficiency, a primary immune deficiency, which can result in the onset of one or more serious infections within the first months of life. Early in life, the child was infected with cytomegalovirus (CMV), a latent virus related to herpes that has significant morbidity and high mortality rates in immune compromised people. Initially, the patient had received a bone marrow transplant, but the CMV could not be cleared with the drug therapy he received after transplant, Dr. Bollard said.

Conventional treatment using antiviral agents is expensive and toxic and can be ineffective. Transfer of virus-specific T cytotoxic cells is seen as an alternative means of preventing and treating these infections. The hospital takes donor cells and manufactures them in the lab to fight specific viruses and/or cancer. The cells are given to the patients in the outpatient clinic, in a procedure that takes less than five minutes. The cytotoxic T-cells usually take within two to six weeks after which time the patient may no longer need other medications to treat or prevent infection.

We give these cells to the patient and then we hope that in a couple of weeks the CMV viral load falls to very low levels or even zero, Dr. Bollard said. This patient is 6 months old. By giving these T-cells, he can get off the drug therapy and spare his kidneys from the toxicity of the antiviral drugs.

The world has great expectations that stem cell research one day will revolutionize medicine. But in order to exploit the potential of stem cells, we need to understand how their development is regulated. Now researchers from University of Southern Denmark offer new insight.

Stem cells are cells that are able to develop into different specialized cell types with specific functions in the body. In adult humans these cells play an important role in tissue regeneration. The potential to act as repair cells can be exploited for disease control of e.g. Parkinson's or diabetes, which are diseases caused by the death of specialized cells. By manipulating the stem cells, they can be directed to develop into various specialized cell types. This however, requires knowledge of the processes that regulate their development.

Now Danish researchers from University of Southern Denmark report a new discovery that provides valuable insight into basic mechanisms of stem cell differentiation. The discovery could lead to new ways of making stem cells develop into exactly the type of cells that a physician may need for treating a disease.

"We have discovered that proteins called transcription factors work together in a new and complex way to reprogram the DNA strand when a stem cell develops into a specific cell type. Until now we thought that only a few transcription factors were responsible for this reprogramming, but that is not the case", explain postdoc Rasmus Siersbaek, Professor Susanne Mandrup and ph.d. Atefeh Rabiee from Department of Biochemistry and Molecular Biology at the University of Southern Denmark.

"An incredibly complex and previously unknown interplay between transcription factors takes place at specific locations in the cell's DNA, which we call 'hotspots'. This interplay at 'hotspots' appears to be of great importance for the development of stem cells. In the future it will therefore be very important to explore these 'hotspots' and the interplay between transcription factors in these regions in order to better understand the mechanisms that control the development of stem cells", explains Rasmus Siersbaek.

"When we understand these mechanisms, we have much better tools to make a stem cell develop in the direction we wish", he says.

Siersbaek, Mandrup and their colleagues made the discovery while studying how stem cells develop into fat cells. The Mandrup research group is interested in this differentiation process, because fundamental understanding of this will allow researchers to manipulate fat cell formation.

"We know that there are two types of fat cells; brown and white. The white fat cells store fat, while brown fat cells actually increase combustion of fat. Brown fat cells are found in especially infants, but adults also have varying amounts of these cells.

"If we manage to find ways to make stem cells develop into brown rather than white fat cells, it may be possible to reduce the development of obesity. Our findings open new possibilities to do this by focusing on the specific sites on the DNA where proteins work together", the researchers explain.

BEIRUT: Fat removal and a non-surgical facelift at the same time might sound like a two-for-one offer too good to be true. But that is a pretty common combination at the Innovi Stem Cell Therapy Clinic, where doctors extract stem cells from the bodys fat to do any number of cosmetic cleanups, from scar removal to diminishing fine lines and wrinkles.

The clinic opened five months ago in the Beirut neighborhood of Sodeco, bringing Lebanon its first specialized center in stem cell research.

Around the world at any given medical conference, from fields as diverse as orthopedics to dentistry, stem cells have become one of the main events, as researchers believe these undifferentiated cells hold the cure to some of the gravest human diseases: cancer, diabetes, multiple sclerosis, to name a few.

In a country like Lebanon, stem cell specialists figured the best way to support their research was to offer one of the most in-demand medical procedures: cosmetic surgery.

Walking through the halls of the elegant, albeit quaint, clinic, one will see top-of-the-line fat freezing technology, equipment for laser hair removal and facilities where doctors carry out medical face peels and stretch mark treatment.

They also offer Ozone therapy, which uses pure oxygen that can supposedly alleviate a range of maladies from skin disorders and premature aging to chronic pain.

But we are not a beauty clinic, said one of the doctors, who asked not to be identified due to Lebanons strict medical advertising laws.

These cosmetic procedures complement their work in stem cells, a far less understood and rapidly evolving area of medicine. Innovi, for example, has built the Middle Easts only stem cell bank, where up to 19,000 vials can be frozen and preserved with liquid nitrogen. The closet housing the bank, which looks like an enormous washing machine, now holds the stem cells of a modest 10 clients.

The clinic has become a hub for various stem cells research. Doctors have visited from Europe and a Syrian doctor is now working with a couple to try and grow sperm from the stem cells of a man with aspermia.

But cosmetic treatments and stem cells go well together as doctors have been using fat-derived cells, also called adipose stem cells, as a Botox-like filler for almost a decade.

A breakthrough for rejuvenating aging skin today includes topical stem cells rich in Growth Factors. These are non-embryonic stem cells.

Collagen is lost during the aging process as production slows down, a contributing factor in the formation of wrinkles, lines, sagging and thinning of skin.

"A very effective way to reduce wrinkles, improve skin quality and boost collagen levels is through Human Fibroblast Conditioned Media," says Kathy Heshelow, founder of Sublime Beauty. "Human Fibroblast Conditioned Media contains key ingredients for rejuvenation of skinespecially natural Growth Factors and other proteins."

2 reasons why these Growth Factors are key for anti-aging skin care:

1) Growth Factors, when used topically, stimulate skin to create more collagen. Results include smoother, healthier skin with diminished wrinkles. Collagen is the structure holding up skin, essential for smoothness.

2) Growth Factors help to replace and regenerate the nutrients needed by skin for rejuvenation. It promotes skin tissue repair and strengthens the elastic fibers which give the skin its softness and suppleness.

"We added our stem cell serum to the Sublime Beauty line for those that wanted a higher end, scientific formula," says Heshelow. "Our serum is of high purity with no fillers and is made in the U.S under strict conditions."

Expensive to make, Heshelow says the Sublime Beauty serum is less expensive than many similar serums found on the market, which can range from $300 to $500. "Our serum retails under $160," Heshelow says.

Use twice daily and see first results in about 2 weeks.

2 Reasons Why Growth Factors and Stem Cells are a Breakthough for Aging Skin, Says Sublime Beauty

On his journey from Birmingham boy to Hollywood star David Harewood has shared the silver screen with Leonardo Di Caprio and earned an MBE for services to drama.

But the Homeland actor says his finest moment came away from the cameras and the red carpet.

Seven years ago David received a telephone call from the Anthony Nolan Trust. Someone somewhere had the blood cancer leukaemia and was in desperate need of a bone marrow transplant to help them beat the disease.

David was the closest match.

David, 48, says: The call came completely out of the blue, I felt like I had won the lottery. It was like a giant finger in the sky pointing me out and saying, its you. I immediately wanted to do whatever I could to help.

The transplant was initially scheduled for a few months later, but those plans had to be hastily revised while RADA-trained actor David was in Romania filming The Last Enemy for BBC One.

I had another call to say my recipient had taken a turn for the worse, says David, who is best known for playing CIA counter-terrorism chief David Este in the hit US spy drama Homeland.

They couldnt wait until I finished filming as they might not make it. They needed my stem cells urgently, it was horrifying.

Thankfully David was due a break in filming, which he used to flew straight home to the UK. A nurse then visited him at home every morning for four days, giving him injections to boost his stem cell production.

On the fifth day David went to Harley Street in London to have his stem cells harvested. He was hooked up to a machine that took blood from one arm, filtered out the vital stems cells that would replace his recipients bone marrow and fed the blood back into his body through a needle in the other arm.

Doctors and scientists in Southampton have completed their first hip surgery with a 3D printed implant and bone stem cell graft.

The 3D printed hip, made from titanium, was designed using the patient's CT scan and CAD CAM (computer aided design and computer aided manufacturing) technology, meaning it was designed to the patient's exact specifications and measurements.

The implant will provide a new socket for the ball of the femur bone to enter. Behind the implant and between the pelvis, doctors have inserted a graft containing bone stem cells.

The graft acts as a filler for the loss of bone. The patient's own bone marrow cells have been added to the graft to provide a source of bone stem cells to encourage bone regeneration behind and around the implant.

Southampton doctors believe this is a game changer. Douglas Dunlop, Consultant Orthopaedic Surgeon, conducted the operation at Southampton General Hospital. He says: "The benefits to the patient through this pioneering procedure are numerous. The titanium used to make the hip is more durable and has been printed to match the patient's exact measurements -- this should improve fit and could recue the risk of having to have another surgery.

"The bone graft material that has been used has excellent biocompatibility and strength and will fill the defect behind the bone well, fusing it all together."

Over the past decade Mr Dunlop and Professor Richard Oreffo, at the University of Southampton, have developed a translational research programme to drive bone formation using patient skeletal stem cells in orthopaedics.

The graft used in this operation is made up of a bone scaffold that allows blood to flow through it. Stem cells from the bone marrow will attach to the material and grow new bone. This will support the 3D printed hip implant.

Professor Oreffo comments: "The 3D printing of the implant in titanium, from CT scans of the patient and stem cell graft is cutting edge and offers the possibility of improved outcomes for patients.

"Fractures and bone loss due to trauma or disease are a significant clinical and socioeconomic problem. Growing bone at the point of injury alongside a hip implant that has been designed to the exact fit of the patient is exciting and offers real opportunities for improved recovery and quality of life."
