Newswise Led by Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research member Dr. Hanna Mikkola, UCLA scientists have discovered a unique protein that is integral to the self-renewal of hematopoietic stem cells (HSCs) during human development.

This discovery lays the groundwork for researchers to generate HSCs in the lab (in vitro) that better mirror those that develop in their natural environment (in vivo). This could lead to improved therapies for blood-related diseases and cancers by enabling the creation of patient-specific blood stem cells for transplantation.

The findings are reported online November 13, 2014, ahead of print in the journal Cell Stem Cell.

The research community has long sought to harness the promise of pluripotent stem cells (PSCs) to overcome a significant roadblock in making cell-based therapies blood and immune diseases more broadly available, which has been hampered by the inability to generate and expand human HSCs in culture. HSCs are the blood forming cells that serve as the critical link between PSCs and fully differentiated cells of the blood system. The ability of HSCs to self-renew (replicate themselves) and differentiate to all blood cell types, is determined in part by the environment that the stem cell came from, called the niche.

In the five-year study, Mikkola and Drs. Sacha Prashad and Vincenzo Calvanese, members of Mikkolas lab and lead authors of the study, investigated a unique HSC surface protein called GPI-80. They found that it was produced by a specific subpopulation of human fetal hematopoietic cells that were the only group that could self-renew and differentiate into various blood cell types. They also found that this subpopulation of hematopoietic cells was the sole population able to permanently integrate into and thrive within the blood system of a recipient mouse.

Mikkola and colleagues further discovered that GPI-80 identifies HSCs during multiple phases of human HSC development and migration. These include the early first trimester of fetal development when newly generated HSCs can be found in the placenta, and the second trimester when HSCs are actively replicating in the fetal liver and the fetal bone marrow.

We found that whatever HSC niche we investigated, we could use GPI-80 as the best determinant to find the stem cell as it was being generated or colonized different hematopoietic tissues, said Mikkola, associate professor of molecular, cell and development biology at UCLA and also a member of the Jonsson Comprehensive Cancer Center. Moreover, loss of GPI-80 caused the stem cells to differentiate. This essentially tells us that GPI-80 must be present to make HSCs. We now have a very unique marker for investigating how human hematopoietic cells develop, migrate and function.

Mikkolas team is actively exploring different stages of human HSC development and PSC differentiation based on the GPI-80 marker, and comparing how blood stem cells are being generated in vitro and in vivo. This paves the way for scientists to redirect PSCs into patient-specific HSCs for transplantation into the patient without the need to find a suitable donor.

TOWIE tonight will feature a fundraising event for the blood cancer charity and bone marrow register Anthony Nolan, in support of Bobby Norris' mum Kym.

The finale of the ITVBe show will centre around the gala - with a few TOWIE stars reportedly planning surprise fundraising stunts!

Bobby Norris started the campaign #SaveBobbysMum in the summer [PH]

OK! Online columnist Bobby Norris launched a campaign for the charity in the summer after his mum Kym, 54, was diagnosed with leukaemia.

The #SaveBobbysMum campaign led to an astonishing 750% increase in sign-ups for the bone marrow register, but a match for Kym is yet to be found.

TOWIE stars including Chloe Sims have backed the campaign [PH]

Bobby said: "Both me and my mum were over the moon to hear about these huge increases in potential donors."

"It's given us something positive to focus on at a really difficult time."

Bobby Norris has shared this sweet snap of himself with mum Kym [PH]

He added: "For the donor, it's probably just a case of sitting still for a few hours while the stem cells are taken out of their blood.

Researchers at Lund University in Sweden have made a major breakthrough in Parkinson's disease treatment by developing stem cell-derived brain cells that can replace the cells lost due to the disease, thus paving the way for the first stem cell transplant treatment for Parkinsons patients.

Parkinson's disease, which affects about 10 million people worldwide, is a degenerative nervous system condition which causes tremors, muscle weakness, stiffness, and loss in mobility. Parkinson's is caused by loss of dopamine-producing neurons in the brain. Dopamine is an essential neurotransmitter that is required for regulating movement and emotions.

In this study, for the first time ever, the researchers were able to convert human embryonic stem cells into dopamine producing neurons, which behaved like native dopamine cells lost in the disease.

The study was led by Malin Parmar, associate professor in Lund's Department of Medicine, and conducted at both Lund University and at MIRCen in Paris as part of the EU networks NeuroStemCell and NeuroStemcellRepair.

According to Medical News Today, the researchers produced rat models of Parkinson's disease by destroying the dopamine cells in one part of the rat's brain, and then they transplanted the new dopamine producing stem cell neurons. These next generation dopamine neurons were found to survive long term, restore the lost dopamine, and form long distance connections to the correct parts of the brain when transplanted into rats. Most excitingly, these transplanted stem cells reversed the damage from the disease.

As the new dopamine neurons have the same properties and functions of native cells lost in Parkinson's disease and can be produced in unlimited quantities from stem cell lines, this treatment shows promise in moving into clinical applications as stem cell transplants for Parkinsons.

"This study shows that we can now produce fully functioning dopamine neurons from stem cells. These cells have the same ability as the brains normal dopamine cells to not only reach but also to connect to their target area over longer distances. This has been our goal for some time, and the next step is to produce the same cells under the necessary regulations for human use. Our hope is that they are ready for clinical studies in about three years", says Malin Parmar.

Human embryonic stem cells (ESC) are powerful treatment options due to their ability to change into any cell type in the body. However, it is difficult to get them to change into the desired cell types, and research efforts are also hampered due to the ethical concerns associated with embryonic stem cells.

The study is published in the journal,Cell Stem Cell, titled Human ESC-Derived Dopamine Neurons Show Similar Preclinical Efficacy and Potency to Fetal Neurons when Grafted in a Rat Model of Parkinsons Disease.

Abstract Embryoid body (EB) formation is a common intermediate during in vitro differentiation of pluripotent stem cells into specialized cell types. We have optimized the slow-turning, lateral vessel (STLV) for large scale and homogenous EB production from mouse embryonic stem cells. The effects of inoculating different cell numbers, time of EB adherence to gelatin-coated dishes, and rotation speed for optimal EB formation and cardiac differentiation were investigated. Using 3x105 cells/ml, 10 rpm rotary speed and plating of EBs onto gelatin-coated surfaces three days after culture, were the best parameters for optimal size and EB quality on consequent cardiac differentiation. These optimized parameters enrich cardiac differentiation in ES cells when using the STLV method.

Sabah becomes third to provide bone marrow transplant

KOTA KINABALU: The Sabah Women and Children's Hospital in Likas became the third government hospital in the country to provide bone marrow transplant after General Hospital Kuala Lumpur (GHKL) and Ampang Hospital.

State Health Director Dr Christina Rundi (pic) said, Tuesday, the Bone Marrow Transplant Unit is housed on the 7th Floor of the Radiotherapy and Nuclear Medicine Centre of the hospital.

At the official handover of the hospital to the State Health Department in April, last year, she mentioned that bone marrow transplant (also called stem cell transplant) would be possible in Sabah in the near future.

"Since then, we have made the necessary preparations to set up the Bone Marrow Transplant Unit.

Our nurses went for training at the Ampang Hospital in Kuala Lumpur while we procured the equipment such as stem cell processor and blood irradiator.

"We are fortunate to have the services of Paediatric Haemato-Oncologist, Dr Asohan Thevarajah who reported for work in July.

"And on Oct. 31, our dream came true when the Sabah Women and Children's Hospital performed the first bone marrow transplant on a 12-year-old leukaemic girl from Tuaran," she confirmed, when contacted.

The stem cell processor arrived last December followed by the blood irradiator in August this year. The purpose of the second machine is to sterilise the bone marrow donor's blood to reduce the risk of "graft (donor) versus host (patient)" disease.

A bone marrow transplant is a procedure to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Bone marrow is the soft tissue inside the hollow part of bones which helps form blood cells. Stem cells are immature cells in the bone marrow that give rise to all of one's blood cells.

How donation is done

Stem cell donation: For peripheral bloodstream cell donation, stem cells are filtered from the donor's blood in a nonsurgical outpatient procedure. Donors may experience head or muscle aches that go away shortly after the donation. They are typically back to their normal routine in one to two days.

Marrow donation: This is a surgical, usually outpatient, procedure using anesthesia. Holes are drilled into the patient's spine to get the marrow. Donors may feel soreness in the lower back afterward. Recovery takes two to seven days.

Outcomes: Survival rate for recipients was 69 percent for unrelated donors and 79 percent for related donors in 2010, the most recent year for which figures are available, according to the U.S. Department of Health and Human Services.

Be the Match is a national registry that connects patients with their donor match for a marrow or umbilical cord blood transplant. The registry is looking for diverse donors between age 18 and 44. Information: 800-627-7692 or BeTheMatch.org

Something was killing his wife from within, and Todd Miller had no idea what it was.

He didnt understand why she needed more than 100 blood transfusions. He couldnt fathom why Joselyn, a healthy person who barely got the sniffles, suddenly struggled to lift her arms.

The symptoms started in April 2012, soon after the Millers returned to their Laguna Beach home from the New Orleans Jazz Festival. Joselyn Millers arm and thigh muscles were so tight, she could barely move them.

They saw 10 specialists. No one could figure out what it was.

The second neurologist they saw suspected it was a very rare disease Shulmans syndrome, or eosinophilic fasciitis. According to the National Organization for Rare Disorders, only 300 known cases have ever been recorded in medical literature.

CHENNAI: It is harder for natives of Tamil Nadu to find a matching donor for a stem cell transplant compared to other states in the country. The suspected villain: Their genes.

A study published recently in British medical journal 'The Lancet' found that the likelihood of finding a matching stem cell donor for patients with blood-related problems in Tamil Nadu is 44.2% provided the registry had 10 lakh donors. The situation is the opposite in Haryana, with people in that state having the best chances (81.2%) of finding a donor.

Experts say consanguineous marriages are to blame. Consanguineous marriages increase the chances of patients finding a match within their small community but limit the possibility of finding one from a general donor pool.

"Unlike in other countries, stem cell variation in India is complex and dependent on ethnic variation," said Dr Dolly Daniel, professor of the department of transfusion medicine at Christian Medical College, Vellore, who was party of the study team. "Our aim was to find the size and genetic composition of each region and its impact on the proportion of patients who will be able to ?nd a suitable match."

She said Tamil Nadu could be at the tail-end of the list of states they surveyed because of inbreeding and a limited number of donors.

Stem cells are used to regenerate and repair diseased or damaged tissues. Adult stem cells are drawn from bone marrow, blood and the umbilical cord and are used to treat blood-related ailments like leukemia, thalassemia and as well as immunodeficiency.

The possibility of finding a matching stem cell donor within the family is around 30%.

"Finding a matching stem cell donor for the remaining 70% is a complex process. Most seek a graft from registries of unrelated adult donors or banked umbilical cord blood units," said Dr P Srinivasan, co-founder and chairman of Jeevan Stem Cell Bank.

Although the India stem cell industry is estimated to touch $540 million (Rs 3,250 crore) by 2015, the study noted that in terms of the number of donors, India has lagged in meeting demand. The study surveyed 10 adult donor and umbilical cord bank registries and clinical transplant centres in India and studied stem cells of 26 239 individuals.

The possibility of finding a perfect match within India is an average of 14.4% for a registry size of 25,000 and touches 60.6% for a size of 10 lakh. Registries in the country currently have around 1 lakh donors. The study said only when Indian registries have more than 2 lakh donors would patients have a good chance of finding the right match.

MIAMI (PRWEB) November 11, 2014

GlobalStemCellsGroup, Inc. has announced plans to host a minimum of four international symposiums on stem cell research in 2015. The symposiums will be held in three Latin American countriesChile, Mexico and Colombiain which Global Stem Cells has established state-of-the-art stem cell clinics staffed with expert medical personnel trained in regenerative medicine, through the Regenestem Network.

The fourth symposium will be held in Miami.

The decision follows the success of the Global Stem Cells Groups first International Symposium on Stem Cells and Regenerative Medicine, held Oct. 2, 3 and 4 in Buenos Aires, Argentina. Global Stem Cells Group CEO Benito Novas says the Buenos Aires event, combined with its steady growth of new clinics throughout Latin America, has provided additional motivation to schedule more stem cell symposiums in an effort to further educate the medical community on the latest advancements in stem cell therapies.

Thanks to Global Stem Cells Groups growing network of world-class stem cell researchers, treatment practitioners and investors committed to advancing stem cell medicine, the company is rapidly moving closer to its goal of helping physicians to bring treatments into their offices for the benefit of patients.

More than 900 physicians, researchers and regenerative medicine experts from around the world attended the Buenos Aires symposium, and Novas expects that number to grow with upcoming conferences.

We will continue to bring together a variety of committed stem cell advocates from the U.S., Mexico, Greece, Hong Kong and other regions around the globe, to be joined by a team of knowledgeable speakers, each one presenting the future of regenerative medicine in their field of specialty, Novas says.

Regenerative medicine as a field is still in its infancy, according to Global Stem Cell Group President and CEO Benito Novas.

Our objective is to [open a dialogue among the worlds medical and scientific communities in order to advance stem cell technologies and translate them into point of care medicine to the best of out abilities, Novas says. Our mission is to bring the benefits of stem cell therapies to the physicians office safely, efficacy and compliance with the highest standards of care with safety, efficacy and complying with the highest standard of care the world has to offer.

The purpose of each symposium is to bring top stem cell scientists together to share their knowledge and expertise in regenerative medicine, and begin the process of separating myths from facts when it comes to stem cell science and technology.

Stem Cells Help Victim of Spinal Cord Injury to Walk

The motor neurons that innervate muscle fibres are essential for motor activity. Their degeneration in many diseases causes paralysis and often death among patients. Researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (I-Stem - Inserm/AFM/UEVE), in collaboration with CNRS and Paris Descartes University, have recently developed a new approach to better control the differentiation of human pluripotent stem cells, and thus produce different populations of motor neurons from these cells in only 14 days. This discovery, published in Nature Biotechnology, will make it possible to expand the production process for these neurons, leading to more rapid progress in understanding diseases of the motor system, such as infantile spinal amyotrophy or amyotrophic lateral sclerosis (ALS).

Human pluripotent stem cells have the ability to give rise to every cell in the body. To understand and control their potential for differentiation in vitro is to offer unprecedented opportunities for regenerative medicine and for advancing the study of physiopathological mechanisms and the quest for therapeutic strategies. However, the development and realisation of these clinical applications is often limited by the inability to obtain specialised cells such as motor neurons from human pluripotent stem cells in an efficient and targeted manner. This inefficiency is partly due to a poor understanding of the molecular mechanisms controlling the differentiation of these cells.

Inserm researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (I-Stem - Inserm/French Muscular Dystrophy Association [AFM]/University of vry Val d'Essonne [UEVE]), in collaboration with CNRS and Paris-Descartes University, have developed an innovative approach to study the differentiation of human stem cells and thus produce many types of cells in an optimal manner.

"The targeted differentiation of human pluripotent stem cells is often a long and rather inefficient process. This is the case when obtaining motor neurons, although these are affected in many diseases. Today, we obtain these neurons with our approach in only 14 days, nearly twice as fast as before, and with a homogeneity rarely achieved," explains Ccile Martinat, an Inserm Research Fellow at I-Stem.

To achieve this result, the researchers studied the interactions between some molecules that control embryonic development. These studies have made it possible to both better understand the mechanisms governing the generation of these neurons during development, and develop an optimal "recipe" for producing them efficiently and rapidly.

"We are now able to produce and hence study different populations of neurons affected to various degrees in diseases that cause the degeneration of motor neurons. We plan to study why some neurons are affected and why others are preserved," adds Stphane Nedelec, an Inserm researcher in Ccile Martinat's team.

In the medium term, the approach should contribute to the development of treatments for paralytic diseases such as infantile spinal muscular amyotrophy or amyotrophic lateral sclerosis. "Rapid access to large quantities of neurons will be useful for testing a significant number of pharmacological drugs in order to identify those capable of preventing the death of motor neurons," concludes Ccile Martinat.

Production of human motor neurons from stem cells gaining speed

The ASTIS trial (Autologous Stem cell Transplantation International Scleroderma), launched in 2001, evaluated the efficacy of autologous haematopoietic stem cell transplantation (HSCT) in patients with systemic sclerosis. A key point to safe use of HSCT is a correct evaluation of cardiac condition, and a close follow up for cardiac complications. In a letter to the Editor published in The Journal of the American Medical Association, entitled Cardiac Assessment Before Stem Cell Transplantation for Systemic Sclerosis, Dr. Burt at the Division of Immunotherapy, Northwestern University and colleagues highlight the importance of performing extensive cardiopulmonary screening in patients with severe forms of systemic sclerosis before administrating HSCT.

HSCT therapy first involves harvestingpatients stem cells. Since Scleroderma, also known as systemic sclerosis, is a chronic systemic autoimmune disease (autoimmune diseases are characterized by a hyper-reactive response of the immune response against substances, and tissues normally present in the body), thesecond step of the process involves destroyingpatients hyper-reactive immune system usingchemotherapy. Afterward, the patients harvested stem cells will be injected back into the body. The objective is to reset the patient immune system to normal standards and thus stop the process of scleroderma.

Systemic sclerosis is associated with many cardiac complications, including intrinsic myocardial ischemia and fibrosis, left ventricular diastolic dysfunction, and pericardial disease. While the criteria for exclusion inthe ASTIS trial was mean pulmonary artery pressure greater than 50 mm Hg by echo-cardiogram or cardiac catheterization, theauthors emphasize that this does not exclude pulmonary arterial hypertension. Despite the fact that2009 guidelines updatedtheir information and described pulmonary arterial hypertension as a mean pulmonary artery pressure higher than 25 mm Hg, the authors cautioned that a significant amount of attention has to be dedicated toassessing cardiac risks in these patients to prevent treatment-related mortality.

AP Glowing: Model Kate Moss

For someone who has mature skin, it is annoying watching 20-somethings with blemish-less complexions worrying about wrinkles and crowfeet. No one seems to be concerned about those over 40 who, for the better part of their 20s and 30s, were busy cooking, cleaning and washing up instead of pandering to their skin.

So when Page 3 Salon, in Race Course, issued an invitation to try its new award-winning skin therapy for mature skin all the way from Spain, one jumped at it. It is supposed to be the same treatment celebrities such as Elton John, Penelope Cruz, Jemima Khan and Kate Moss use to keep their skin glowing and young.

If you have mature skin, this treatment is the one for you, says a spokesperson for the brand Skeyndor (meaning golden skin), who was in Coimbatore recently to promote the product and train the beauty therapists at Page 3 the correct way to use the products. Skeyndor has over 200 products to suit other skin types, too. R&D is the companys strength and it is also one of the first in the cosmetic industry to use nano-technology for skin care.

She says, comfortingly, that my skin is still not too bad and sits me down to explain what I can do to keep it from aging too fast.

The special facial that is recommended for me uses products that are gentle on the skin and one particular treatment that has the same effect as Botox. And, without being invasive at all. Before the facial commences a photograph is taken focussing on the problem areas of the skin. And once the hour-plus, soothing treatment is done (so soothing that I fall asleep), it is time for another photograph. And strangely enough, even the sceptic in me has to admit there is a discernible difference in skin texture. It felt more elastic and from the photographs I could tell there were fewer few lines.

The beautician recommends a series of facials at regular intervals (depending on the condition of the skin and the amount of repair it needs). The salon will make a schedule for you and remind you when it is time to come for a treatment. The salon also provides you with tips on home care. Page 3 offers two high-end special facials. Both sound tempting: One is called Revisit your youth and the other Turn Back Time.

Anyone who is 35 plus can go for the Turn Back Time facial, says Shan of Page 3. This treatment is supposed to arrest ageing and promote the production of epidermal stem cells. It holds off the fine lines, wrinkles and sagging. Revisit Your Youth on the other hand is corrective. It promises to reduce the crows feet and lines that have already appeared on your face. The products in this line work like Botox without being invasive, says Shan.

The products are available at the salon. For appointments and details call:0422-4393333/4223331

Dopamine-making neurons derived from human embryonic stem cells.

See correction at end of article.

A rat model of Parkinson's disease has been successfully treated with neurons derived from human embryonic stem cells, according to a study led by Swedish scientists. Its a promising sign for scientists at The Scripps Research Institute and Scripps Health who hope to perform similar therapy on Parkinsons patients, using artificial embryonic stem cells.

In rats and people, neurons that make the neurotransmitter dopamine are essential for normal movement. The cells are destroyed in Parkinson's, leading to the difficulty in movement that characterizes the disease.

Researchers transplanted dopamine-producing cells grown from human embryonic stem cells into the brains of rats whose own dopamine-making neurons had been destroyed. The rats were immune-suppressed so they would not reject the cells. Within five months, the transplanted cells boosted dopamine production to normal levels, restoring normal movement in the rats.

The study was published Thursday in the journal Cell Stem Cell. The senior author was Malin Parmar of Lund University in Lund, Sweden.

The results support the Scripps approach of using the artificial embryonic stem cells, called induced pluripotent stem cells, said Jeanne Loring, who heads the Center for Regenerative Medicine at The Scripps Research Institute in La Jolla. Loring is part of a group called Summit 4 Stem Cell that's raising funds to treat eight Parkinson's patients with their own IPS cells.

Particularly significant is the study's comparison of the effects of dopamine-making neurons derived from fetal cells to that of embryonic stem cells, Loring said by email.

"In the 1980s and 1990s, there were several clinical trials that showed that grafts of fetal brain containing the precursors of dopamine neurons could reverse the effects of Parkinson's disease in some patients," Loring said. "We, and the others developing stem cell therapies, based our plans on the results of those studies, but no one had ever directly compared fetal tissue and human pluripotent stem cell-derived dopamine neurons in an animal model of PD."

Induced pluripotent stem cells appear to have much the same capacity as human embryonic stem cells to generate different tissues and organs.

Magnifisio dashed home strongly over 1400m to win Saturdays Lee-Steere Stakes at Ascot. Picture: Westernracepix

Sprinter Smoko will have stem cell therapy at Murdoch Veterinary Hospital to a strained suspensory ligament in his off-foreleg.

Vets found Smoko had strained the ligament when he pulled up sore following his shock sixth as a $2 favourite to Shining Knight in last Tuesday's Colonel Reeves Stakes (1100m) at Ascot.

Co-trainer Ross Price said Smoko would be sidelined for months.

"He will go to Murdoch where they will look at him and see about stem cell therapy," he said.

"In about 10 days we will take him up there and see what they can do. It is then going to be five months off and hoping."

Smoko was a $6.50 chance in Saturday week's Winterbottom Stakes (1200m) before he was scratched. WA's hopes of winning back the Group 1 weight-for-age hinge on Magnifisio, Shining Knight and Testamezzo, with Barakey in doubt after struggling to recover from a virus.

"He is still feeling flat and I will have to wait and see if he improves over the next few days," trainer Jim Taylor said.

Magnifisio firmed from $12 into $8 on the TAB yesterday following her strong win at her debut over 1400m in Saturday's Group 2 Lee-Steere Stakes at Ascot.

Melbourne sprinters Angelic Light, Moment Of Change and reigning champion Buffering dominate betting at $4.30, $6.50 and $7.50.

Stem cell therapy for sidelined star Smoko

The day Olivia Cox was diagnosed with Type 1 diabetes at age 16, her mother vowed to find a cure.

"I said to her, "there's someone walking this Earth who has been cured of diabetes, and I'm going to find him," Ruth Cox said.

Cox's search started with a call to Harvard University and ended with a family trip to Lima, Peru. It was at a clinic there that now 18-year-old Olivia and her father, Jeff, 54, who also has diabetes, received an infusion of stem cells designed to wipe out diabetes in their bodies or, at the very least, lessen its impact. The treatment illegal in the United States cost $70,000 for both father and daughter. Two months later, the Niskayuna family is waiting for a transformation and wondering if, in their desperation for a cure, they were snookered by false promises.

Because stem cells can be programmed to become anything from heart muscle to toenails, stem cell therapy can hypothetically be used to treat anything, from baldness to Lou Gehrig's Disease. But the study of regenerative medicine is still nascent in the United States, where it is restricted to procedures that use the patient's own cells, and it has been primarily used in treating cancer a procedure that saved Ruth Cox 13 years ago, when she had breast cancer.

Stem cell treatment using donor cells is more common elsewhere in the world, but with varying results and none that could be described as a cure. An executive order from President Barack Obama opened up funding for stem cell research and there are now more than 4,000 clinical trials under way, some on animals and some recruiting people with various ailments.

The American Diabetes Association strongly supports stem cell research, according to a statement posted on its website, which reads in part:

"Scientists from across the United States and throughout the world, including those involved with the American Diabetes Association believe that stem cell research, especially embryonic stem cell research, holds great promise in the search for a cure and better treatments for diabetes."

Jeff Cox, diagnosed with Type 1 diabetes when he was 11, has suffered none of the complications that often come with the disease neuropathy, loss of vision and heart disease. But Cox said living with diabetes is hell. He pricks his finger at least a dozen times a day to check his blood sugar level, because it is a more precise reading than the glucose monitor he wears. He also wears a pump that he programs to inject him with insulin automatically based on his diet and exercise each day. All the therapies used to treat diabetes are designed to intervene where the pancreas has gone awry.

In Type 1 diabetes, the pancreas doesn't produce insulin due to an autoimmune attack against the beta cell that produces insulin the hormone that converts glucose into energy our bodies need to survive. The Coxes didn't want their daughter to face a lifetime of managing her diabetes. They wanted a cure, and they were willing to take a risk to find it.

In order to treat diabetes with stem cell therapy, pancreatic stem cells isolated from umbilical cord blood that are programmed to produce insulin, plus autologous mesenchymal stem cells from the patient's bone marrow, are injected. Once in the pancreas, the cells are supposed to replicate themselves, gradually replacing the non-insulin producing cells in the host's pancreas. The treatment is conducted in Peru, China, Russia and India and elsewhere, but Zubin Master, a bioethicist at Albany Medical College, said the risks of traveling abroad for stem cell therapy range from paying for an expensive treatment that doesn't work, to cancer and death.

The motor neurons that innervate muscle fibres are essential for motor activity. Their degeneration in many diseases causes paralysis and often death among patients. Researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (I-Stem - Inserm/AFM/UEVE), in collaboration with CNRS and Paris Descartes University, have recently developed a new approach to better control the differentiation of human pluripotent stem cells, and thus produce different populations of motor neurons from these cells in only 14 days. This discovery, published in Nature Biotechnology, will make it possible to expand the production process for these neurons, leading to more rapid progress in understanding diseases of the motor system, such as infantile spinal amyotrophy or amyotrophic lateral sclerosis (ALS).

Human pluripotent stem cells have the ability to give rise to every cell in the body. To understand and control their potential for differentiation in vitro is to offer unprecedented opportunities for regenerative medicine and for advancing the study of physiopathological mechanisms and the quest for therapeutic strategies. However, the development and realisation of these clinical applications is often limited by the inability to obtain specialised cells such as motor neurons from human pluripotent stem cells in an efficient and targeted manner. This inefficiency is partly due to a poor understanding of the molecular mechanisms controlling the differentiation of these cells.

Inserm researchers at the Institute for Stem Cell Therapy and Exploration of Monogenic Diseases (I-Stem - Inserm/French Muscular Dystrophy Association [AFM]/University of vry Val d'Essonne [UEVE]), in collaboration with CNRS and Paris-Descartes University, have developed an innovative approach to study the differentiation of human stem cells and thus produce many types of cells in an optimal manner.

"The targeted differentiation of human pluripotent stem cells is often a long and rather inefficient process. This is the case when obtaining motor neurons, although these are affected in many diseases. Today, we obtain these neurons with our approach in only 14 days, nearly twice as fast as before, and with a homogeneity rarely achieved," explains Ccile Martinat, an Inserm Research Fellow at I-Stem.

To achieve this result, the researchers studied the interactions between some molecules that control embryonic development. These studies have made it possible to both better understand the mechanisms governing the generation of these neurons during development, and develop an optimal "recipe" for producing them efficiently and rapidly.

"We are now able to produce and hence study different populations of neurons affected to various degrees in diseases that cause the degeneration of motor neurons. We plan to study why some neurons are affected and why others are preserved," adds Stphane Nedelec, an Inserm researcher in Ccile Martinat's team.
