Celling Biosciences Sponsors 7th Annual Stem Cell Summit

By daniellenierenberg

AUSTIN, Texas, Feb. 21, 2012 /PRNewswire/ -- Celling Biosciences announces a sponsorship of the 7th Annual Stem Cell Summit being held on February 21st at Bridgewaters New York in New York City. The Stem Cell Summit is consistently the premiere venue for the world's leaders in regenerative medicine to network and promote next generation technologies and cell therapies.

The meeting will feature more than 30 thought leaders in stem cell therapy including Dr. Kenneth Pettine of the Orthopedic Stem Cell Institute in Loveland, Colorado.  Dr. Pettine has teamed up with Celling Biosciences' SpineSmith Division to present "Adult Stem Cell Therapy for Orthopedic and Spine Conditions Resulting from Injury or Aging."  Dr. Pettine has become an innovator in the regenerative cell therapy market and believes "regenerative therapies will become the next standard of care in treating many orthopedic conditions." 

Following the Stem Cell Summit, Dr. Pettine will be presenting a discussion on regenerative therapies to the trainers and medical staff attending this year's NFL combine.  The NFL has recently gained attention from Peyton Manning going oversees to receive a cell therapy treatment for his cervical spine condition.  Dr. Pettine envisions a day when these professional athletes stop going to foreign countries to receive medical treatment.

The Orthopedic Stem Cell Institute provides state-of-the-art regenerative cell therapy using Celling Biosciences' ART 21 system. The ART 21 system processes bone marrow from the patient at the point of care to consistently produce a concentrate of regenerative cells with high yields of mononuclear stem cells in less than 15 minutes.  Celling Biosciences provides the cell separation systems along with the biomaterials and devices necessary to recreate the environment to promote healing. 

Kevin Dunworth, founder of Celling Biosciences, believes regenerative cell therapy has more to do with creating the optimal environment then just providing cells.  "We believe autologous cell therapy is a viable solution but physicians need to understand that these cells require the necessary substrate for delivery and the proper techniques for retrieval.  Our focus has been on providing not only cell separation technologies, medical devices and biomaterials but also the registered nurses to deliver the service so physicians can have the most consistent, reliable and predictable regenerative cell therapy for their patients."

Stem cells a fix for 'broken hearts'?

By daniellenierenberg

When a piece of muscle in a person’s heart dies from lack of blood flow, it scars over and is lost.  But a team of researchers from the Cedars-Sinai Heart Institute in Los Angeles has proven that those muscles may not necessarily be gone forever.

In a ground-breaking study that may change how heart attacks are treated, Dr. Eduardo Marban and his team used stem cells to re-grow damaged heart muscle.  In the 17 patients who received the therapy, Marban measured an average 50 percent reduction in the size of the scar tissue

“One of the holy grails in medicine has been the use of medicine to achieve regeneration,” Marban said.  “Patients that were treated not only experienced shrinkage of their scars, but also new growth of their heart muscle, which is very exciting.”

The stem cells were not derived from embryos, but instead were developed from the patients’ own hearts.  Marban’s team inserted a catheter into the diseased hearts and took a small biopsy of muscle.  In the laboratory, the tissue was manipulated into producing stem cells.  After a few weeks of marinating in culture, researchers had enough stem cells to re-inject them into the patients’ hearts.  Over the course of a year, the stem cells took root in cardiac tissue, encouraging the heart to create new muscle and blood vessels.  In other words, the heart actually began to mend itself.

Click here to see an animation of how the process works.

“We’ve achieved what we have achieved using adult stem cells – in this case – actually specifically from a patient’s own heart back into the same patient.   There’s no ethical issues with that – there’s no destruction of embryos.  There’s no reason to worry about immune rejection."

While similar research has been done using stem cells from bone marrow, this is the first time that stem cells derived from a patient’s own cardiac tissue have been used.

Marban believes this therapy could be broadly used in many of the 5 to 7 million Americans who suffer from heart disease every year.  And he said the applications could go well beyond diseased hearts.

“If we can do that in the heart, I don’t see any reason, conceptually, why we couldn’t do it in kidneys for example, or pancreas or other organs that have very limited regenerative capacity,” Marban said.

While the procedure may be a revolutionary medical technique, there are still a few more puzzling questions about the research that Marban would like to investigate further.  For example, while the patients grew new heart muscle and saw a dramatic reduction in scar tissue, the actual function of their hearts did not show a significant improvement.  And it appeared the stem cells themselves may not have turned into cardiac muscle, but rather they stimulated the heart to produce new muscle cells.

Because this was a “Phase 1” study, it was really meant to measure whether the procedure was safe.  Of the 17 patients who were given the stem cell injections, six experienced “serious adverse events,” but only one was regarded to be possibly related to the treatment.  

The potential success of this research could hold a lot of promise for the millions of Americans who suffer from heart disease each and every year, which is the leading cause of death in the United States.  If his future experiments yield the same results as this initial study, Marban believes he could be offering this therapy to patients within four years – and that could go a long way in mending all of America’s broken hearts.

Horizon in new super-cell elite

By daniellenierenberg

Cambridge personalised medicines pioneer Horizon Discovery Ltd has landed another showpiece deal as part of a new super-cell consortium.

Business Weekly understands that the UK company stands to make a seven-figure haul over the lifetime of an EU-funded project aimed at understanding hES cell differentiation control.

Horizon provides research tools to support the development of personalised medicines. It has joined the EU-FP7 funded ‘4D-Cell-Fate’ consortium  whose aim is to shed light on how stem cell re-programming and differentiation is regulated at the epigenetic level.

As a member of the consortium, Horizon will generate cell-lines harbouring endogenous pathway reporter genes and labelled versions of specific epigenetic target proteins to study their function.

Commercialisation of the output of the programme will be governed by a consortium agreement defined by EU regulation.

4DCellFate brings together 12 groups from nine countries, including academics, research-intensive SMEs, and Pharma, each an international leader in its field, combining expertise in a wide range of cutting-edge technologies and scientific approaches.

The aim of the 4D CellFate project, which is currently funded for five years, is to establish an integrated approach to explore the structure and function of the large multi-protein epigenetic complexes that are involved in control of stem cell self-renewal, lineage commitment, and differentiation.

Horizon will use its proprietary virally-mediated gene-engineering technology, GENESIS™, to alter endogenous genes in hES cells (e.g. via tagging with GFP and HaloTag® technologies) with unprecedented accuracy and precision.

By gaining a greater insight into how Polycomb Repressive Complexes (PRCs), and Nucleosome Remodelling and Deacetylation complexes (NuRD) control stem cell differentiation, it is hoped that better methods will be identified to generate ethical sources of ‘iPS’ stem cells and direct the fate of stem cells into the many forms of specific tissue types that are needed for disease therapy.

Dr Chris Torrance, CSO of Horizon, said: “Generating stem cells and differentiated cell types with greater precision, definition and safety are key areas for delivering on the great promise that stem cell-based therapies could bring to many disease areas.

“Horizon’s gene targeting technology will play a key role in helping to dissect key biological pathways in the fate of stem cells as part of the 4D Cell Fate project. Through this process, new and important approaches to disease therapy will be determined.”

CEO Dr Darrin Disley added: “Our company has a commitment to active involvement in cutting-edge research with leading experts in translational fields, including bringing the power of rAAV-mediated gene targeting technology to the 4D Cell Fate project.”

Scarred Hearts Can Be Mended With Stem Cell Therapy

By daniellenierenberg

February 15, 2012, 12:06 AM EST

By Ryan Flinn

(Adds comment from researcher in 13th paragraph.)

Feb. 14 (Bloomberg) -- Stem cells grown from patients’ own cardiac tissue can heal damage once thought to be permanent after a heart attack, according to a study that suggests the experimental approach may one day help stave off heart failure.

In a trial of 25 heart-attack patients, 17 who got the stem cell treatment showed a 50 percent reduction in cardiac scar tissue compared with no improvement for the eight who received standard care. The results, from the first of three sets of clinical trials generally needed for regulatory approval, were published today in the medical journal Lancet.

“The findings in this paper are encouraging,” Deepak Srivastava, director of the San Francisco-based Gladstone Institute of Cardiovascular Disease, said in an interview. “There’s a dire need for new therapies for people with heart failure, it’s still the No. 1 cause of death in men and women.”

The study, by researchers from Cedars-Sinai Heart Institute in Los Angeles and Johns Hopkins University in Baltimore, tested the approach in patients who recently suffered a heart attack, with the goal that repairing the damage might help stave off failure. While patients getting the stem cells showed no more improvement in heart function than those who didn’t get the experimental therapy, the theory is that new tissue regenerated by the stem cells can strengthen the heart, said Eduardo Marban, the study’s lead author.

“What our trial was designed to do is to reverse the injury once it’s happened,” said Marban, director of Cedars- Sinai Heart Institute. “The quantitative outcome that we had in this paper is to shift patients from a high-risk group to a low- risk group.”

Minimally Invasive

The stem cells were implanted within five weeks after patients suffering heart attacks. Doctors removed heart tissue, about the size of half a raisin, using a minimally invasive procedure that involved a thin needle threaded through the veins. After cultivating the stem cells from the tissue, doctors reinserted them using a second minimally invasive procedure. Patients got 12.5 million cells to 25 million cells.

A year after the procedure, six patients in the stem cell group had serious side effects, including a heart attack, chest pain, a coronary bypass, implantation of a defibrillator, and two other events unrelated to the heart. One of patient’s side effects were possibly linked to the treatment, the study found.

While the main goal of the trial was to examine the safety of the procedure, the decrease in scar tissue in those treated merits a larger study that focuses on broader clinical outcomes, researchers said in the paper.

Heart Regeneration

“If we can regenerate the whole heart, then the patient would be completely normal,” Marban said. “We haven’t fulfilled that yet, but we’ve gotten rid of half of the injury, and that’s a good start.”

While the study resulted in patients having an increase in muscle mass and a shrinkage of scar size, the amount of blood flowing out of the heart, or the ejection fraction, wasn’t different between the control group and stem-cell therapy group. The measurement is important because poor blood flow deprives the body of oxygen and nutrients it needs to function properly, Srivastava said.

“The patients don’t have a functional benefit in this study,” said Srivastava, who wasn’t not involved in the trial.

The technology is being developed by closely held Capricor Inc., which will further test it in 200 patients for the second of three trials typically required for regulatory approval. Marban is a founder of the Los Angeles-based company and chairman of its scientific advisory board. His wife, Linda Marban, is also a founder and chief executive officer.

“We’d like to study patients who are much sicker and see if we can actually spare them early death, or the need for a heart transplant, or a device,” Eduardo Marban said.

Bone gives 'some' heart healing

By daniellenierenberg

14 February 2012 Last updated at 19:10 ET By James Gallagher Health and science reporter, BBC News

Bone marrow stem cell therapy offers "moderate improvement" to heart attack patients, according to a large UK review of clinical trials.

The analysis by the Cochrane Collaboration looked at 33 trials involving more than 1,700 patients.

It said longer-term studies were needed to see if the experimental therapy affected life expectancy.

The review comes a day after doctors reported the first case of using heart cells to heal heart attack damage.

If a patient survives a heart attack, dead heart muscle is replaced with scar tissue - leaving the patient weaker and possibly on a lifetime of medicine.

Researchers are beginning to show that taking cells from a heart, growing millions of new heart cells in the laboratory and pumping those back into the heart may reduce scar tissue and lead to new heart muscle.

Stem cell therapy may also reduce the number of patients who later die or suffer from heart failure, but currently there is a lack of statistically significant evidence based on the small number of patients treated so far”

End Quote Dr Enca Martin-Rendon Lead researcher

However, the trials are at a very early stage and in only a handful of patients. Using a similar technique with cells taken from the bone marrow, which is a prime source of stem cells, has a much longer pedigree.

The report by Cochrane pooled the data from all 33 bone marrow trials which had taken place up to 2011.

It concluded that bone marrow therapy "may lead to a moderate long-term improvement" in heart function which "might be clinically very important".

Longer life uncertain

It said there was still no evidence of "any significant effect on mortality" in comparison with standard treatment. However, this may be due to the size of the studies and that patients were followed for a short period of time.

Lead author Dr Enca Martin-Rendon, from NHS Blood and Transplant at the John Radcliffe Hospital in Oxford, said: "This new treatment may lead to moderate improvement in heart function over standard treatments.

"Stem cell therapy may also reduce the number of patients who later die or suffer from heart failure, but currently there is a lack of statistically significant evidence based on the small number of patients treated so far."

Prof Anthony Mathur, from Barts and the London School of Medicine and Dentistry, is leading the largest ever trial of stem cells in heart attack patients.

It starts this year, however, he told the BBC that the results could come quite quickly. Three thousand patients across Europe will take part. They will be injected with stem cells five days after a heart attack and then followed for two years to see if the therapy affects life expectancy.

Prof Peter Weissberg, medical director at the British Heart Foundation, said: "This review reflects the consensus of opinion about these trials - cell therapy has a modestly beneficial effect.

"Despite that, no-one knows why, or even if, cell therapies will translate into better survival or sustained improvement in damaged hearts. It's much too early to judge the likely long-term benefits."

Radiation therapy transforms breast cancer cells into cancer stem cells

By daniellenierenberg

Washington, Feb 14 (ANI): Researchers have shown for the first time that radiation treatment -despite killing half of all tumour cells during every cycle - transforms other cancer cells into treatment-resistant breast cancer stem cells.

According to researchers with the UCLA Department of Radiation Oncology at UCLA's Jonsson Comprehensive Cancer Center, the generation of these breast cancer stem cells counteracts the otherwise highly efficient radiation treatment.

If scientists can uncover the mechanisms and prevent this transformation from occurring, radiation treatment for breast cancer could become even more effective, said study senior author Dr. Frank Pajonk, an associate professor of radiation oncology and Jonsson Cancer Center researcher.

"We found that these induced breast cancer stem cells (iBCSC) were generated by radiation-induced activation of the same cellular pathways used to reprogram normal cells into induced pluripotent stem cells (iPS) in regenerative medicine," said Pajonk, who also is a scientist with the Eli and Edythe Broad Center of Regenerative Medicine at UCLA.

"It was remarkable that these breast cancers used the same reprogramming pathways to fight back against the radiation treatment."

"Controlling the radiation resistance of breast cancer stem cells and the generation of new iBCSC during radiation treatment may ultimately improve curability and may allow for de-escalation of the total radiation doses currently given to breast cancer patients, thereby reducing acute and long-term adverse effects," the study stated.

There are very few breast cancer stem cells in a larger pool of breast cancer cells. In this study, Pajonk and his team eliminated the smaller pool of breast cancer stem cells and then irradiated the remaining breast cancer cells and placed them into mice.

Using a unique imaging system Pajonk and his team developed to visualize cancer stem cells, the researchers were able to observe their initial generation into iBCSC in response to the radiation treatment.

The newly generated iBCSC were remarkably similar to breast cancer stem cells found in tumors that had not been irradiated, Pajonk said.

The team also found that the iBCSC had a more than 30-fold increased ability to form tumors compared to the non-irradiated breast cancer cells from which they originated.

Pajonk said that the study unites the competing models of clonal evolution and the hierarchical organization of breast cancers, as it suggests that undisturbed, growing tumors maintain a small number of cancer stem cells.

However, if challenged by various stressors that threaten their numbers, including ionizing radiation, the breast cancer cells generate iBCSC that may, together with the surviving cancer stem cells, repopulate the tumour.

"What is really exciting about this study is that it gives us a much more complex understanding of the interaction of radiation with cancer cells that goes far beyond DNA damage and cell killing," Pajonk said.

"The study may carry enormous potential to make radiation even better."

Pajonk stressed that breast cancer patients should not be alarmed by the study findings and should continue to undergo radiation if recommended by their oncologists.

"Radiation is an extremely powerful tool in the fight against breast cancer," he said.

"If we can uncover the mechanism driving this transformation, we may be able to stop it and make the therapy even more powerful," Pajonk added.

The study has been published in the online edition of peer-reviewed journal Stem Cells. (ANI)

Radiation treatment generates cancer stem cells from less aggressive breast cancer cells, study suggests

By daniellenierenberg

ScienceDaily (Feb. 13, 2012) — Breast cancer stem cells are thought to be the sole source of tumor recurrence and are known to be resistant to radiation therapy and don't respond well to chemotherapy.

Now, researchers with the UCLA Department of Radiation Oncology at UCLA's Jonsson Comprehensive Cancer Center report for the first time that radiation treatment -- despite killing half of all tumor cells during every treatment -- transforms other cancer cells into treatment-resistant breast cancer stem cells.

The generation of these breast cancer stem cells counteracts the otherwise highly efficient radiation treatment.

"It was remarkable that these breast cancers used the same reprogramming pathways to fight back against the radiation treatment."

The study recently appeared in the early online edition of the peer-reviewed journal Stem Cells.

Stem cell treatments change girl's life

By daniellenierenberg

PIEDMONT, Okla. -- Stem cell research is one of the newest and most exciting areas of study. Experts believe these tiny unwritten cells hold the keys to curing a number of diseases and debilitating injuries. But here in the U.S., stem cell research isn't moving fast enough for a growing number of families.

This is the story of an Oklahoma family that traveled to China for cutting-edge stem cell treatment not offered in the US.

Cora Beth Taylor walks a different road than most will ever travel.

Her journey is filled with obstacles, heartbreak and triumph.

Cora, William and Tate Taylor are triplets born premature.

The brothers have never shown any signs of prematurity.

But Cora, at about a year old, started falling behind developmentally.

By 18 months she had been diagnosed with Cerebral Palsy.

Cora has never had any cognitive delays.

She's a super-smart little gal but her muscles haven't developed properly.

It's devastating; they just won't cooperate.

Cora's parents, Kevin and Beth Taylor, have tried everything for their little girl; that is, everything available in the U.S.

Last year, Piedmont Schools raised the money to help the Taylors take Cora to China for treatment, close to $50,000.

Research hospitals in China are using stem cells from donor umbilical cord blood to treat children with Cerebral Palsy.

Beth Taylor says, "That was a difficult decision to make to take your child to a foreign country for medical treatments. Living in the US you feel like this is the best there is."

The Taylors spent 37 days in China.

Cora Beth had eight stem cell transfusions.

Through a spinal tap, doctors put the cells into her spinal column where they penetrate the blood-brain barrier and get to work.

Critics are quick to point out this area of regenerative medicine has largely unverified effectiveness. Results are often anecdotal and the FDA is a long way from approving this type of experimental treatment for America.

Though the Taylors are convinced and here's why.

Beth Taylor said, "Within the first couple of weeks we could see changes. We could see definite improvements in strength and balance."

Cora had never been able to do a sit-up in her life ever; she did her first in China.

Nine-year-old Cora remembers, "The thing that I was most happy about accomplishing was a sit up. Because I'd tried to do a sit up before going to China but I just couldn't do it."

Now, Cora Beth can do 20.

The most notable change has been Cora's walk.

This third-grader had never gone to school without her walker.

Today she walks the halls without it; she hasn't used it in months.

She recently competed in a beauty pageant in her hometown of Piedmont, without the help of her walker as well.

Cora says, "So, I'm really excited. I don't think there's anything that I couldn't accomplish."

Doctors say Cora’s stem cells will continue to mature over the next few years.

For her, there are many milestones ahead.

In the US, Duke University is studying stem cell treatments for children with Cerebral Palsy.

Right now they don't have FDA clearance to use donor stem-cells.

Experts say treatment similar to Cora Beth's Chinese therapy is years away in the U.S.

Dr. Ramaswamy on Dormant Tumor Cells and Resistance – Video

By daniellenierenberg

13-02-2012 12:31 Sridhar Ramaswamy, MD, Tucker Gosnell Investigator and Associate Professor of Medicine, Massachusetts General Hospital Cancer Center, Harvard Medical School, Broad Institute of Harvard and MIT, and Harvard Stem Cell Institute, discusses ongoing research into drug tolerance and resistance, specifically the roll of dormant cancer cells. If a tumor goes into remission as a result of a cancer drug and then recurs it is likely that the tumor will still respond to the initial treatment. In the dormant state the cells are resistance, in the original they are sensitive. The exact mechanism behind this has yet to be discovered. In some cases giving a course, stopping, and then continuing later on can create an additive effect, an idea that Ramaswamy calls a drug holiday. A comparison is underway between drug and non-drug induced dormant cells in order to find the mechanism that causes resistance. The ultimate goal of the research is to be able to predict and stop drug resistance.

Bone marrow recipient meets donor who gave him gift of life

By daniellenierenberg

BOCA RATON—

A physician from Indianapolis met the woman who saved his life on Sunday morning, providing an emotional kick-off for the second annual Walk for Life, sponsored by the Gift of Life Bone Marrow Foundation.

"It's almost like a total out of body experience," said Scott Savader, 53, moments after he embraced former Sunrise resident Jill Rubin, who provided the stem cells that were transplanted into Savader's body nearly two years ago.

As the two met for the first time, about 300 people cheered before heading off on a 5K walk at Florida Atlantic University. The effort is part of a campaign to raise awareness and raise $100,000 for lab tests necessary to match donors and recipients.

Savader said receiving the transplant was "like being plucked from a fire or a sinking car. There is a bond there now that transcends just knowing somebody. If not for her generosity, I would have died."

Each year, 10,000 people in the U.S. are diagnosed with a disease treatable with a bone marrow transplant. Yet only about half find the donor who could save them, according to Jay Feinberg, the Delray Beach resident who started the foundation after he was diagnosed with an aggressive form of leukemia.

He received a transplant in 1995 and has since dedicated his life to making matches for others.

Savader, a radiologist, was diagnosed with myelofibrosis in 2008.

Rubin, 45, a physical therapist, said she registered as a bone marrow donor 10 years ago while attending a fair in Plantation. She and her family have since moved to Deland.

"This is very emotional for me," said Rubin as she and Savader posed for pictures.

After spending a little time with Savader and his family Sunday, Rubin said she felt even better about her gift to him.

She also learned that Savader grew up and went to high school in Cooper City. "Small world," she said.

Temperatures in the 40s and a chilly wind did little to dampen enthusiasm for the walk. Participants were inspired by Savader and Rubin and other success stories.

Among the latter were 6-year-old Matthew Welling, on hand with his parents Michael and Susie Welling of Port Chester, N.Y., and Boca Raton resident Jill Goldsmith, who donated the bone marrow that reversed the boy's osteoporosis in 2007.

"It was an amazing, life-changing experience," said Goldsmith, 50, as she watched Matthew dance happily around a field at the university.

"What I had to do to save a life was so easy," said Goldsmith. "And to see him now, well, I feel proud and honored and so blessed."

During last year's walk, more than 1,000 new donors were added to the registry and resulted in 14 matches for patients throughout the U.S. They joined a total registry of nearly 200,000, said Feinberg.

Volunteering to become a potential donor begins with an oral swab that is then tested for tissue type. Most of the foundation's money goes toward paying for those lab tests, which cost about $55 each, said Feinberg.

By daniellenierenberg

01-02-2012 13:37 Meet founders of Cord Blood Registry, Tom and Wendy. Hear why they started CBR -- a family business dedicated to helping people live healthier lives through cord blood stem cell medicine. Today, CBR has grown, but the attention to healthy families is the same. For more than 15 years, Cord Blood Registry has led the umbilical cord banking industry in technical innovations and provided families with peace of mind and hope. CBR's experience and dedication to quality has enabled CBR to help more clients use their cord blood stem cells in treatments than any other family bank. Our research and development efforts are focused on helping leading clinical researchers advance stem cell regenerative medicine that may help families in the future. Ultimate use of cord blood stem cells will be determined by the treating physician who will consider if they are applicable for the condition and should come from the patient or a suitable donor (like an HLA matched sibling). There is no guarantee that treatments being studied in the laboratory or in clinical trials will be available in the future. CBR is the preferred choice of OB/Gyns. © 2011 Cord Blood Registry.

Leukemia Survivor Meets His Bone Marrow Donor – Video

By daniellenierenberg

16-01-2012 16:52 On October 1st, 2009 I was diagnosed with Leukemia. After 9 months of intense chemotherapy treatments, the decision was made that I would need a bone marrow transplant. A suitable donor was not found within my family so I would have to rely on the national Be The Match® marrow registry to locate one for me. A match was found and on August 18th, 2010 I underwent a stem-cell transplant using an unrelated donors stem-cells. Today, I'm cancer free! Her generosity and selflessness has allowed me to call myself a 'survivor'. This video was captured of my donor and I meeting face-to-face for the first time. It was truly an amazing experience! I have made it my life's mission to 'Pay it Forward'. After transplant, I started working for The Leukemia and Lymphoma Society where I am able to use my wounds for good on a daily basis. My diagnoses was not in vain! To learn how you can help create a world without cancer, visit http://www.LLS.org and to join the Be The Match® registry, visit join.marrow.org

New study makes key finding in stem cell self-renewal

By daniellenierenberg

The work has implications in two areas. In cancer treatment, it is desirable to inhibit cell proliferation. But to grow adult stem cells for transplantation to victims of injury or disease, it would be desirable to sustain proliferation until a sufficient number of cells have been produced to make a usable organ or tissue.

The study gives researchers a handle on how those two competing processes might be controlled. It was performed at the university's Hormel Institute in Austin, Minn., using mouse stem cells. The researchers, led by Hormel Institute Executive Director Zigang Dong and Associate Director Ann M. Bode, have published a report in the journal Nature Structure and Molecular Biology.

"This is breakthrough research and provides the molecular basis for development of regenerative medicine," said Dong. "This research will aid in the development of the next generation of drugs that make repairs and regeneration within the body possible following damage by such factors as cancer, aging, heart disease, diabetes, or paralysis caused by traumatic injury."

The mechanism centers on a protein called Klf4, which is found in embryonic stem cells and whose activities include keeping those cells dividing and proliferating rather than differentiating. That is, Klf4 maintains the character of the stem cells; this process is called self-renewal. The researchers discovered that two enzymes, called ERK1 and ERK2, inactivate Klf; this allows the cells to begin differentiating into adult cells.

The two enzymes are part of a "bucket brigade" of signals that starts when a chemical messenger arrives from outside the embryonic stem cells. Chemical messages are passed to inside the cells, resulting in, among other things, the two enzymes swinging into action.

The researchers also discovered how the enzymes control Klf4. They attach a small molecule--phosphate, consisting of phosphorus and oxygen--to Klf4. This "tag" marks it for destruction by the cellular machinery that recycles proteins.

Further, they found that suppressing the activity of the two enzymes allows the stem cells to maintain their self-renewal and resist differentiation. Taken together, their findings paint a picture of the ERK1 and ERK2 enzymes as major players in deciding the future of embryonic stem cells--and potentially cancer cells, whose rapid growth mirrors the behavior of the stem cells.

Klf4 is one of several factors used to reprogram certain adult skin cells to become a form of stem cells called iPS (induced pluripotent stem) cells, which behave similarly to embryonic stem cells. Also, many studies have shown that Klf4 can either activate or repress the functioning of genes and, in certain contexts, act as either an oncogene (that promotes cancer) or a tumor suppressor. Given these and their own findings reported here, the Hormel Institute researchers suggest that the self-renewal program of cancer cells might resemble that of embryonic stem cells.

"Although the functions of Klf4 in cancer are controversial, several reports suggest Klf4 is involved in human cancer development," Bode said.

NOC Interview 2: Big Pharma – Video

01-02-2012 21:36 Notes from the interview: Nicholas Anderson - Author, NOC: British Secret Operations Big Pharma... must be careful in discussing reason for writing books is in part because of something along these lines medical doctor helped to exfiltrate from soviet union end of 1991 doctor wanted to meet... nicholas anderson flew to meet in moscow... bottom line: he claimed to have number of effective treatments and cures... MIND YOU... he's not trying to get your hopes up, but you should look into alternate treatments natural remedies. stem cell, energetic medicine is more detail in the book? when the book was written, it was non-fiction. but it didn't last to be a non-fiction novel. former secret operations must be cleared. large majority that was redacted or cleared from the fiction novel was about big pharma. certain things -are- in the book. also know that nicholas anderson was skeptical about these items first. even so, he wondered why aren't these alternative cures more widely known? the doctor appeared on a primetime show and the media prevented him from saying what he wanted to say... in a couple examples, they removed things he had said. they said the -opposite- of what he actually said. it was then that he realized he was on to something and he saw that happening. did this doctor have access to this medicine in the soviet union or was it secretive? in the beginning of communism, they did come up with things in medicine that the west never did come up with. this doctor had ...
