NEW YORK (TheStreet) -- Shares ofNeoStem (NBS) plummeted 25.52% to $5.05 in late morning trading Tuesdayafter the biotech company announced poor results from a trial of its proprietary cardiac stem-cell therapy NBS10.

NBS10, which used to be called AMR-001, missed two primary endpoints in the study to test the therapy's efficacy.The stem-cell therapy comesfrom a patient's own bone marrow and is injected into patients after a heart attack. The stem cells are then supposed to help blood flow and build cardiac muscle.

NeoStem's trial used non-invasive imaging to monitor blood flow through the heart six months after a one dose of NBS10 or a placebo. The study showed no difference between NBS and placebo, NeoStem said.

WESTWOOD (CBSLA.com) Doctors say a groundbreaking stem cell therapy treatment out of UCLA may have cured Bubble Baby syndrome once and for all.

KNX 1070s Brian Ping reports Dr. Donald Kohn has perfected a gene therapy that has now cured 18 children born without an immune system, known as ADA-deficient severe combined immunodeficiency (SCID).

Only weeks after giving birth to fraternal twins in 2012, Alysia and Christian Padilla-Vaccaro found out their daughter Evangelinas immune system was so deficient that she could have no exposure to the outside world.

After enrolling their daughter in Dr. Donald Kohns revolutionary stem cell gene therapy treatment which was nearly three decades in the making doctors extracted stem cells from the bone marrow in Evangelinas hip, then used a modified mouse virus to correct her faulty gene before replacing the marrow.

You hear the words mouse virus and you want to run the other way, said mom Alysia. But they modify it so that its teaching it to do something that they want it to do, which is put something in there that was missing.

Evangelinas new immune system developed without side effects and she is now living a healthy normal life.

Her mother Alysia said while the process was difficult for any mom to go through, it was all worth it.

UCLA Doctors Hail Potential Cure For Bubble Baby Syndrome

Inject a cocktail of undifferentiated stem cellsinto a patient who has suffered a heart attack, and days or even weekslater, the stem cells transform into cardiac cells and rebuild the damaged heart muscle. Months later, the patient has a "new" healthy heart.It's a great story. But so far, the proof remains elusive though not for a lack of trying.

The latest company to fulfill this ambitious scenario is NeoStem (NBS) which presented disappointing (but not surprising) results from a small study of its proprietary cardiac stem-cell therapy NBS10 at the American Heart Association annual meeting Monday. NeoStem tried to put some positive spin on the bad news but shares are down 25% to $5.10.

NBS10, formerly known as AMR-001, is an autologous stem-cell therapy derived from a patient's own bone marrow. When injected back into patients following a heart attack, the stem cells are supposed torestore blood flow, rebuild damaged cardiac muscle and improve function.

Except in NeoStem's study, NBS10 fell short on two primary endpoints designed to assess the therapy's efficacy. The study used non-invasive imaging to assess blood flow through the heart, six months after a single infusion of NBS10 or a placebo. There was no difference between NBS and placebo, NeoStem said.

The study's other co-primary efficacy endpoint was a measurement of adverse cardiac "MACE" events --defined as cardiovascular death, a repeatheart attack, heart failure hospitalization and coronary revascularization. To date, 17% of patientstreated with NBS10 have suffered a MACE event compared to 19% of patients in the placebo arm -- a difference which was not statistically significant.

NeoStem said NBS10 therapy was safe relative to placebo and that no patients treated with the stem cells have died compared to three deaths in the placebo patients. But with only one year of follow up on a small number of patients, any claims about a mortality benefit are clinically meaningless.

Chronic myeloid leukemia develops when a gene mutates and causes an enzyme to become hyperactive, causing blood-forming stem cells in the bone marrow to grow rapidly into abnormal cells. The enzyme, Abl-kinase, is a member of the "kinase" family of enzymes, which serve as an "on" or "off" switch for many functions in our cells. In chronic myeloid leukemia, the hyperactive Abl-kinase is targeted with drugs that bind to a specific part of the enzyme and block it, aiming to ultimately kill the fast-growing cancer cell. However, treatments are often limited by the fact that the cancer cells can adapt to resist drugs. EPFL scientists have identified an alternative part of Abl-kinase on which drugs can bind and act with a reduced risk of drug resistance. Their work is published in Nature Communications.

Abl-kinase and leukemia

Abl-kinase can turn "on" molecules that are involved in many cell functions including cell growth. In chronic myeloid leukemia, the chromosome that contains the gene for Abl-kinase swaps a section with another chromosome, causing what is known as the "Philadelphia chromosome". When this mutation takes place in the blood stem cells in the bone marrow, Abl-kinase fuses with another protein, turning into a deregulated, hyperactive enzyme. This causes large numbers of blood-forming stem cells to grow into an abnormal type of white blood cell, which gives rise to chronic myeloid leukemia.

To treat this type of leukemia we use drugs that specifically bind and block a part of Abl-kinase called the "active site". As the name suggests, this is the part of the enzyme that binds molecules to turn them on. Therefore, blocking the active site with a drug stops the hyperactivity of Abl-kinase caused by the Philadelphia mutation and slow down or even abolishes the production of abnormal cancerous blood cells. The problem is that targeting the active site of Abl-kinase often causes the cancer cells to adapt and develop drug resistance, making them harder to kill.

An indirect path against resistance

A team of researchers led by Oliver Hantschel at EPFL (ISREC) has now discovered a new way to indirectly inhibit the activity of Abl-kinase. The scientists systematically made small, strategic mutations to Abl-kinase that caused its 3D structure to change. Then they tested each mutant version of the enzyme to see if its function would change.

Hantschel's team built on previous studies showing that Abl-kinase is indirectly controlled by another part of itself called the "SH2 region", which is located close to the active site. Normally, the SH2 region regulates the active site by opening and closing it. But under the Philadelphia mutation, that regulation is lost. What the scientists discovered was that when the Philadelphia mutation takes effect, the SH2 region actually "clamps" open the active site of Abl-kinase and forces it to go into overdrive.

A large-scale trial conducted in India has shown that stem cell therapy does not work in stroke patientsREUTERS

A study conducted on 120 patients in India has shown that stem cell treatment is not effective in treating paralysis resulting from a stroke.

The research which is thefirst large-scale study conducted in Indiacompared outcomes in those treated with stem cells to others and found no difference, reports Down to Earth.

While 60 patients with some form of disability of limbs caused by a stroke were given conventional treatment, an equal number received bone marrow stem cells in addition. All had experienced a stroke 3-4 weeks before the trial.

"We found that at the end of the first month, patients with stem cells showed more improvement compared to the control group. But at the end of the third month and one year, there was no difference," said Kameshwar Prasad, head, Department of Neurology, All India Institute of Medical Sciences (AIIMS), who led the study.

On an average 280 million bone marrow cells were injected, of which blood forming stem cells were around 2.9 million per patient.

The average age of patients in the study was around 50.

The study, published in the current issue of American journal Stroke, was conducted at AIIMS in New Delhi and four other hospitals covering four cities.

The study comes when many others have been suggesting that stem cells could help treat paralysis in stroke patients. The earlier study was done on a small number of patients as compared to the AIIMs study.

More research needs to be done, before stem cells are used in therapy as in India, many private clinics are openly offering stem cell treatment for various diseases.

Stem Cells Treatment Not Useful In Stroke Patients Finds Indian Study

Stem cells are the building blocks of your skin. They have a unique ability to replace damaged and diseased cells. As they divide, they can proliferate for long periods into millions of new skin cells.

As we age, our stem cells lose their potency. Your skin's ability to repair itself just isn't what it used to be. The result can be fine lines, wrinkles, age spots, and sagging skin. But non-embryonic stem cells -- the same stem cells active early in life -- are highly potent. Lifeline anti-aging stem cell serums tap into the potency of these stem cells to help renew your skin.

Scientists at Lifeline Skin Care discovered that human non-embryonic stem cell extracts can help renew skin -- by replacing old cells with healthy new ones. These stem cell extracts help stimulate your own skin's abilities to repair itself. And Lifeline anti-aging stem cell serums were born.

Where Stem Cells in Anti Aging Products Come From

The first types of human stem cells to be studied by researchers were embryonic stem cells, donated from in vitro fertilization labs. But because creating embryonic stem cells involves the destruction of a fertilized human embryo, many people have ethical concerns about the use of such cells.

Lifeline Skin Care (through its parent company, ISCO) is the first company in the world to discover how to create human non-embryonic stem cells -- and how to take extracts from them. As a result, you need never be concerned that a viable human embryo was damaged or destroyed to create these anti-aging products.

The non-embryonic stem cells in Lifeline stem cell serums are derived from unfertilized human oocytes (eggs) which are donated to ISCO from in vitro fertilization labs and clinics.

Lifeline Anti Aging Stem Cell Serums are Based in Science

Lifeline Skin Care's exclusive anti-aging products are a combination of several discoveries and unique high-technology, patent-pending formulations.

Beyond Batten Disease Foundation (BBDF) and the New York Stem Cell Foundation (NYSCF) have been selected as a national innovator by the Milken Institute and will present their breakthrough findings about juvenile Batten disease at the 6th annual Partnering for Cures, November 16-18 in New York City. The presentation will highlight the collaborative efforts of NYSCF, BBDF and Batten Disease Support and Research Association.

Craig and Charlotte Benson established Beyond Batten Disease Foundation in August 2008 after their then five-year-old daughter, Christiane, was diagnosed with juvenile Batten disease. Together with hundreds of families affected by Batten disease, and many more supporters who share their hope and resolve, they are working tirelessly to create a brighter future for Christiane, and all children with Batten disease.

Watch the Benson Family story:

The Benson Family Story

Beyond Batten Disease and the New York Stem Cell Foundation hope to ramp up funding and partnerships to develop stem cell resources to investigate and explore new treatments and ultimately find a cure for juvenile Batten disease, a fatal illness-affecting children as they convene at the FasterCures, conference. The Washington, D.C.-based center of the Milken Institute will bring together nearly 1,000 medical research leaders, investors and decision-makers to forge the collaborations needed to speed and improve outcomes-driven R&D. NYSCF scientists have created the first iPS cells from a neurological disease and the first ever stem cell disease model from any disease. This discovery was named Time Magazine #1 breakthrough in 2008 because it was the first time anyone has made stem cells from a person with a disease and used them to produce the type of cell that degenerated in that patient. Again, in 2012 Time Magazine recognized the Beyond Batten Disease Foundations creation of a rate genetic disease test as a top ten medical breakthrough.

We know the genetic mutations associated with juvenile Batten disease. This partnership will result in stem cell models of juvenile Batten, giving researchers an unprecedented look at how the disease develops, speeding research towards a cure, said Susan L. Solomon, NYSCF Chief Executive Officer.

Working with NYSCF to generate functional neuronal subtypes from patients and families is a stellar example of one of our key strategies in the fight against juvenile Batten disease: creating resource technology with the potential to transform juvenile Batten disease research and accelerate our timeline to a cure, said Danielle M. Kerkovich, PhD, BBDF Principal Scientist.

Juvenile Batten disease begins in early childhood between the ages of five and ten. Initial symptoms typically begin with progressive vision loss, followed by personality changes, behavioral problems, and slowed learning. These symptoms are followed by a progressive loss of motor functions, eventually resulting in wheelchair use and premature death. Seizures and psychiatric symptoms can develop at any point in the disease.

Juvenile Batten disease is one disorder in a group of rare, fatal, inherited disorders known as Batten disease. Over 40 different errors (mutations) in the CLN3 segment of DNA (gene) have been attributed to juvenile Batten disease. The pathological hallmark of juvenile Batten is a buildup of lipopigment in the bodys tissues. It is not known why lipopigment accumulates or why brain and eventually, heart cells are selectively damaged. It is, however, clear that we need disease-specific tools that reflect human disease in order to figure this out and to build therapy.

I have to admit that my first response to these reports out of Britain that stem cells had been successfully used to repair a complete spinal cord transection was skepticism incredulity even. Theyre reporting that a man with a completely severed spinal cord at level T10-T11 is able to walk again! The Guardian gushes! The Daily Mail gets in the act (always a bad sign)! When I read that the patient had an 8mm gap in his spinal cord that had been filling up with scar tissue for the last two years, I was even more doubtful: under the best of conditions, it was unlikely that youd get substantial connectivity across that distance.

So I read the paper. Im less skeptical now, for a couple of reasons. They actually did this experiment on 3 people, and all showed degrees of improvement, although the newspapers are all focusing on just the one who had the greatest change. The gradual changes are all documented thoroughly and believably. And, sad to say, the improvements in the mans motor and sensory ability are more limited and more realistic than most of the accounts would have you think.

The story is actually in accord with what weve seen in stem cell repair of spinal cord injury in rats and mice.

Overall, they found that stem cell treatment results in an average improvement of about 25% over the post-injury performance in both sensory and motor outcomes, though the results can vary widely between animals. For sensory outcomes the degree of improvement tended to increase with the number of cells introduced scientists are often reassured by this sort of dose response, as it suggests a real underlying biologically plausible effect. So the good news is that stem cell therapy does indeed seem to confer a statistically significant improvement over the residual ability of the animals both to move and feel things beyond the spinal injury site.

Significant but far from complete improvement is exactly what wed expect, and that improvement is a very, very good thing. It is an accomplishment to translate animal studies into getting measurable clinical improvements in people.

The basic procedure is straightforward. There is a population of neural cells in humans that do actively and continuously regenerate: the cells of the olfactory bulb. So what they did is remove one of the patients own olfactory bulbs, dissociate it into a soup of isolated cells, and inject them into locations above and below the injury. They also bridged the gap with strips of nerve tissue harvested from the patients leg. The idea is that the proliferating cells and the nerves would provide a nerve growth-friendly environment and build substrate bridges that would stimulate the damaged cells and provide a path for regrowth.

Big bonus: this was an autologous transplant (from the patients own tissues), so there was no worry about immune system rejection. There were legitimate worries about inflammation, doing further damage to the spinal cord, and provoking greater degeneration, and part of the purpose of this work was to assess the safety of the procedure. There were no complications.

Also, Im sure you were worried about this, but the lost olfactory cells also regenerated and the patients completely recovered their sense of smell.

Now heres the clinical assessment. Three patients were operated on; T1 is the one who has made all the news with the most remarkable improvement. There were also three control patients who showed no improvement over the same period.

Neurological function improved in all three transplant recipients (T1, T2, T3) during the first year postsurgery. This included a decrease of muscle spasticity (T1, T2) as well as improvement of sensory (T1, T2, T3) and motor function (T1, T2, T3) below the level of spinal cord injury.

NOTRE DAME - You could be a life saver!

On Friday, November 21, 2014, the Saint Mary's College student club SMC Stands Up To Cancer will hold a bone marrow registration drive on campus.

It'll take place from 11am to 3pm in Reignbeaux Lounge in Le Mans Hall. For a campus map click here.

To participate, you must be between the ages of 18 and 44. It's completely painless to sign up, requiring just a swab of the inside of your cheek to get a sample of cells.

Your genetic information will be added to the Be the Match marrow database, which searches for possible matches for blood cancer patients. Suitable donors can provide bone marrow or peripheral blood stem cells to patients, saving lives.

This will be the second annual bone marrow drive held on Saint Mary's campus. Typically, one person in 540 is a match for a patient with a blood cancer. But a match surfaced out of the 50 registered on campus at the last drive. Allison Lukomski '16, a communicative sciences and disorders major, was a match for a female cancer patient. Lukomski donated peripheral blood stem cells over fall break through a non-surgical procedure.

The bone marrow registration event comes on the heels of the Pink Party Zumbathon, hosted by SMC Stands Up to Cancer, which raised money for cancer research through the national organization Stand Up To Cancer.

Beverly Hills, California (PRWEB) November 17, 2014

Veteran television and movie actor Darius McCrary has received a revolutionary stem cell procedure for his painful knee and ankle. The regenerative medicine procedure with stem cells was performed by Dr. Raj, a top orthopedic doctor in Beverly Hills and Los Angeles.

Darius McCrary is well known for his decade long stint on Family Matters as character Eddie Winslow. He won a Best Young Actor Award for this role along with movie roles in both Mississippi Burning and Big Shots. Currently, Darius appears along with Charlie Sheen in the show Anger Management.

While staying in tip top shape for his career, Darius has developed persistent pain in his right knee and ankle. Rather than seek a regular cortisone injection for pain relief or opt for surgery, he desired the ability to repair the joint damage and achieve pain relief. "I couldn't imagine being immobilized because of injury, so I opted for a stem cell procedure."

The procedures were performed by Dr. Raj, who is a prominent Beverly Hills orthopedic doctor with extensive experience in regenerative medicine. The procedure consisted of a combination of platelet rich plasma therapy along with amniotic derived stem cell therapy. Anecdotal studies are showing that the stem cell procedures for extremity joints allow patients to achieve pain relief and often avoid the need for potentially risky surgery.

Dr. Raj has performed over 100 stem cell procedures for patients who have degenerative arthritis or sports injuries. "Patients do extremely well with the procedures. Minimal risk and there's a huge potential upside!"

With an active acting career, Darius McCrary cannot afford to be distracted with chronic pain. "I'm looking forward to getting back in the gym and going hard without this pain," he stated excitedly. The procedure was filmed and can be seen on Dr. Raj's Facebook page.

To discuss stem cell procedures at Beverly Hills Orthopedic Institute and how they can benefit, call (310) 247-0466.

Marc-Andr Skelling of East Angus needs help. The 23-year-old man has Hodgkins Lymphoma, a cancer affecting the bodys white blood cells and lymph nodes. He has been told that without a viable donation of bone marrow stem cells he has less than a month to live.

We need to find a donor, its urgent, said Muguette Skelling, Marc-Andrs mother. Were inviting everyone, no matter who they are, to register with Hma-Quebec.

Bone marrow is responsible for the production of red and white blood cells in the body and therefore a bone marrow transplant can be an effective treatment for a range of blood related diseases. Depending on the context, individuals can receive a transplant either from another part of their own body, or from an outside donor.

Individuals in good health who are between 18 and 35 years of age can register to donate in Quebec. Registration is done online through the Hma-Quebec website. Once registration is complete, a test kit containing a cheek swab is mailed to the registrant that must then be returned. According to Mnard, the whole process from registration to getting onto the list takes twelve weeks.

A protein that plays a critical role in preventing the development of many types of human cancers has been shown also to inhibit a vital stem cell property called pluripotency, according to a study by researchers at the Stanford University School of Medicine.

Blocking expression of the protein, called retinoblastoma, in mouse cells allowed the researchers to more easily transform them into what are known as induced pluripotent stem cells, or iPS cells. Pluripotent is a term used to describe a cell that is similar to an embryonic stem cell and can become any tissue in the body.

The study provides a direct and unexpected molecular link between cancer and stem cell science through retinoblastoma, or Rb, one of the best known of a class of proteins called tumor suppressors. Although Rb has long been known to control the rate of cell division, the researchers found that it also directly binds and inhibits the expression of genes involved in pluripotency.

"We were very surprised to see that retinoblastoma directly connects control of the cell cycle with pluripotency," said Julien Sage, PhD, associate professor of pediatrics and of genetics. "This is a completely new idea as to how retinoblastoma functions. It physically prevents the reacquisition of stem cellness and pluripotency by inhibiting gene expression."

Marius Wernig, MD, associate professor of pathology, said, "The loss of Rb appears to directly change a cell's identity. Without the protein, the cell is much more developmentally fluid and is easier to reprogram into an iPS cell."

Wernig and Sage, both members of the Stanford Cancer Institute, share senior authorship of the study, which will be published online Nov. 13 in Cell Stem Cell. Postdoctoral scholar Michael Kareta, PhD, is the lead author.

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.
