Vanderbilt-Ingram Cancer Center researchers have identified a new population of intestinal stem cells that may hold clues to the origin of colorectal cancer.

This new stem cell population, reported March 30 in the journal Cell, appears to be relatively quiescent (inactive) in contrast to the recent discovery of intestinal stem cells that multiply rapidly and is marked by a protein, Lrig1, that may act as a "brake" on cell growth and proliferation.

The researchers have also developed a new and clinically relevant mouse model of colorectal cancer that investigators can now use to better understand where and how the disease arises, as well as for probing new therapeutic targets.

Colorectal cancer is the second leading cause of cancer deaths in the United States. These tumors are thought to arise from a series of mutations in intestinal stem cells, which are long-lived, self-renewing cells that gives rise to all cell types in the intestinal tract.

For more than 30 years, scientists believed that intestinal stem cells were primarily quiescent, proliferating only rarely in order to protect the tissue against cancer. Then, in 2007, researchers reported finding a population of intestinal stem cells (marked by the molecule Lgr5) that were highly proliferative.

Those findings "really changed the way we think about intestinal stem cells," said Robert Coffey, Jr., M.D., Ingram Professor of Cancer Research, co-chair of Vanderbilt's Epithelial Biology Center and senior author on the study.

"It came to so dominate the field that it raised the question about whether quiescent stem cells even existand that's where we enter into the picture."

Coffey's lab studies the epidermal growth factor (EGF) signaling pathway which includes a family of receptors known as ErbBs and its role in cancers of epithelial tissues, like the intestinal tract.

Vatican’s Stem-Cell Censorship Sham

Posted: March 30, 2012 at 3:49 am

The Catholic Church has never had a particularly easy relationship with science. After all, this is the institution that sentenced Galileo Galilei as a heretic for his theories on the universe during the Roman Inquisition. Two thousand years later, the church forgave Galileo and called the whole misunderstanding a tragic mutual incomprehension but it remains safe to say the Vatican doesnt have a great track record when it comes to empirical open-mindedness.

So onlookers were surprised when the Vatican announced it would be hosting a global conference on the highly controversial issue of stem-cell research in Rome over four days in late April. The church held a similar conference in 2010 and 2011, which focused on its recommendation that stem-cell research should be limited to adult cells that can be harvested from live donors, not embryonic cells that destroy the source. But this years conference schedule featured some of the worlds foremost experts in embryonic research as keynote speakersleading some scientists to think that the Vatican might actually be looking for enlightenment on the topic.

That was not exactly case. Instead, the Vatican seems to have hoped that by including embryonic researchers in the program, it would appear that these scientists actually endorsed the Vaticans stance.

It might have worked to some extent, but after some of the speakers declined to censor their speeches, the Vatican abruptly canceled the conference altogether. According to the conference website, the event was canceled due to serious economic and logistic-organizational reasons that have completely jeopardized the success of the 3rd International Congress on Responsible Stem Cell Research. The scientists who were planning to attend say they are being stifled instead. I think the only interpretation is that we are being censored, Alan Trounson, president of the California Institute for Regenerative Medicine in San Francisco, said in a statement. It is very disappointing that they are unwilling to hear the truth.

Just what was the Vatican thinking? Inviting embryonic stem-cell researchers to a conference and then denying them the right to talk about their field of expertise was a major gamble. Had the speakers agreed to avoid reference to embryonic research, it would have given the disingenuous impression that they endorse the Holy Sees recommendation on adult stem-cell research only. Did the Vatican really think they could control the scientific community? Apparently so. Father Scott Borgman of the Pontifical Academy for Life, which co-organized the conference, had reportedly asked the speakers to limit their discussions to adult stem-cell research only. George Daly, a leading embryonic researcher with the Childrens Hospital in Boston, says he was actually told not to make embryonic researchhis field of expertisea focal point of his talk. When he told Borgman that he would still be touching on the topic in a historical context, higher-ups in the Vatican reportedly panicked. I had been encouraged to think that the Congress would be a forum for discussion of many areas of common interest to the Vatican and stem cell scientists, regardless of the disagreements over embryonic stem cells, Daly told The Daily Beast. We should all agree that clinical trials of new medical treatments based on stem cells should proceed according to rigorous principles to ensure patients are kept as safe as possible and free from exploitation. And we should all agree that premature claims of therapeutic efficacy and direct marketing of unproven interventions to vulnerable patients is a threat to legitimate attempts to develop experimental stem cell medicines.

With the cancelation of the event, discourse between the two diverse entities will not have a venue. One Vatican official told the Catholic News Service that many of the Vaticans leaders were secretly glad the conference failed. I am infinitely relieved that the church has avoided a major blunder which would have confused the faithful for decades to come, the unnamed source said. The Holy Spirit has certainly shown to be present through those faithful members who drew attention to the ambiguity of the choice of speakers. I hope and pray that a review will be affected of the basis on which these congresses are planned.

Some stem-cell researchers are also relieved the conference wont go on. I personally am very uncomfortable with a scientific meeting run by a church, and one at which only certain types of science and scientists are allowed to attend, blogged Paul Knoepfler, an associate professor of Cell Biology and Human Anatomy at UC Davis School of Medicine who blogs about stem cell research at IPCell.com. Also I cant help but wonder, what would be the reaction if someone like Daley spent a few minutes of his talk discussing his embryonic cell research in a very nonconfrontational way? Would he be tasered or drop through some trap door straight to Hell?

Still, Knoepfler was hopeful. I view the canceled Vatican stem-cell meeting as a missed opportunity for a very much needed, open dialogue about stem cells, he told The Daily Beast. More specifically, I believe the reasons for the cancellation reflect an anti-scientific attitude by the highest level of Vatican leaders. More simply put, the attitude might be summed up by the phrase If you do not think like us, you are not welcome at our meeting, and well go so far as to cancel the whole thing to avoid your presence.

Inviting embryonic stem-cell researchers to a conference and then denying them the right to talk about their field of expertise was a major gamble.

World’s first bedside genetic test gets green light by prestigious medical publication

Posted: March 29, 2012 at 3:28 pm

Dr. Derek So and Dr. Jason Roberts. (CNW Group/OTTAWA HEART INSTITUTE, UNIVERSITY OF OTTAWA)

OTTAWA, March 29, 2012 /CNW/ - Developed in Canada and conducted by researchers from the University of Ottawa Heart Institute (UOHI), in partnership with Spartan Bioscience, the world's first bedside genetic test has received acknowledgment by The Lancet, the world's leading general medical journal.

The article Point-of-care genetic testing for personalisation of antiplatelet treatment (RAPID GENE): a prospective, randomised, proof-of-concept trial, reports on the use of a simple cheek swab test, the Spartan RX CYP2C19, performed by nurses at the patient's bedside. This revolutionary technology allows doctors to rapidly identify patients with a genetic variant known as CYP2C19*2. Cardiac stent patients with this variant are at risk of reacting poorly to standard anti-platelet therapy with Plavix (clopidogrel).

The study demonstrated that tailored drug treatment therapy made possible by the genetic testing successfully protected all of the patients with the at-risk genetic variant from subsequent adverse events, while 30 per cent of patients treated with standard therapy did not receive adequate protection.

"For the first time in medicine, nurses were able to perform DNA testing at the patient's bedside. This is a significant step towards the vision of personalized medicine," said Dr. Derek So, Interventional Cardiologist at the University of Ottawa Heart Institute (UOHI), and principal investigator of the RAPID GENE study.

Study Details The RAPID GENE study enrolled 200 patients who were being treated with cardiac stenting for an acute coronary syndrome or stable angina. Patients were randomized to a treatment strategy of rapid point-of-care genotyping and Effient (prasugrel) for CYP2C19*2 carriers, or to standard therapy with Plavix (clopidogrel). The Spartan RX CYP2C19 bedside DNA test was performed by nurses who received a 30-minute training session, but had no prior laboratory training. The test had a sensitivity of 100% and a specificity of 99.4% compared with DNA sequencing. For CYP2C19*2 carriers, treatment with prasugrel completely eliminated High on-treatment Platelet Reactivity (HPR). HPR is a marker for patients at risk of complications after stenting. In contrast, 30.4% of carriers receiving clopidogrel had HPR at 1 week.

About UOHI As Canada's largest and foremost cardiovascular health centre, the University of Ottawa Heart Institute is dedicated to understanding, treating, and preventing heart disease. We deliver high-tech care with a personal touch, shape the way cardiovascular medicine is practiced, and revolutionize cardiac treatment and understanding.

Basketball’s influence on stem cell treatments in sports medicine

Posted: March 29, 2012 at 3:27 pm

As the basketball frenzy that accompanies March Madness draws to the fever pitch of the Final Four, it brings to mind that basketball is a high contact sport. A quick peek at the NBA injured list reveals a catalog of breaks and tears affecting tendons, ligaments and bones.

The pressure to improve performance and search for quick recoveries has led some celebrity athletes to seek out stem cell treatments overseas and in the U.S. Among NBA players to get stem cell treatments are Jason Kidd, Tracy McGrady, Amar Stoudemire, Allan Houston and Kenyon Martin, according to a Sports Illustrated article.

Dragoo said in a phone interview that the publicity has actually had a negative impact on the development of clinically proven stem cell therapies for orthopedic medicine and how it is perceived.Because of this market pressure, private clinics have been offering stem cells treatments both here in the USA as well as around the world. Often these treatments have not been studied and are not regulated in any way. FDA regulations have also severely limited new clinical trials in stem cell therapy in the USA.

The ethical debate of using embryonic stem cells taken from fetuses has been sidestepped to some extent by the viability of adult stem cells for stem cell therapy. Although the U.S. Food and Drug Administration permits cells being extracted from individuals, transformed into stem cells and re-inserted back into the same person, it requires that the conversion involve no more than water, preservatives and storage products. Anything more than that, the FDA policy goes, would be classified as a drug therapy and need to go through the proper application protocol.

But a much-awaited decision by the U.S. District Court in Washington, DC expected in May that may resolve a four-year old battle between the FDA and Regenerative Science in Colorado could represent a sea change in how autologous adult stem cell treatments are regulated. The FDA is seeking to prevent the company from providing autologous adult stem cell treatment for musculoskeletal and spinal injuries. If the FDA were to lose, anyone with a medical license could develop autologous stem cells and inject them back into patients, without any regulatory oversight, according to a Cell Press article.

Although stem cells there are the focus of numerous clinical trials, they are mainly for cancer and rare diseases, with most being conducted outside the United States. While there have been some developments for sports medicine applications produced by research from academic institutions, there have been no clinical trials for stem cell treatments in sports medicine in the United States because of the U.S. Food and Drug Administrations reservations about using adult stem cells. Despite the laxer regulations in Japan, China and Europe, its not in the financial interest of companies there to spend the money to do clinical trials if they dont have to.

Among the most interesting applications for orthopedic medicine are the restoration of articular cartilage and patching defects in joint cartilage, with the hope of resurfacing arthritic joints in the future, Dragoo said. Stanford is preparing to initiate its own clinical trial next year looking at inducible stem cells.

This technique takes adult cells and make them young again by inserting four genes which makes the cells immature and allows them to be directed into different types of tissues, Dragoo said.

CEO of stem cell company responds to FDA warning letter

Posted: March 29, 2012 at 12:50 am

The head of a stem cell company has responded to a warning letter issued by the U.S. Food and Drug Administration citing several violations at the company which derives stem cells from adipose tissue or body fat.

Dr. Steven Victor of IntelliCell BioSciences said it would be moving to a new facility next month that it believes will address the current good manufacturing practice issues referred to in the warning letter It has also hired consultants with FDA compliance experience that will help bring its new facilities in compliance with the FDA. Victor added that the company will address all of the FDAs observations on April 3.

The New York company received a warning letter dated March 13 that was published on the FDAs website yesterday. The letter said that the process that the company uses to produce stem cells from adipose tissue did not meet the FDAs definition of minimal manipulation for structural tissue such as adipose tissue.

That provision section 1271.10 of the Code of Federal Regulations for Food and Drugs requires that the products, in this case, stem cells, are used for the person the cells are taken from, or a first or secondary relative, not combined with anything else other than water, a preservative, or sterilizing or storage products. It also permits these cells to be used for reproduction. Treatments that do not fall within this provision are classified as a drug.

Although there are numerous clinical trials using stem cells to treat cancer and rare diseases, critics say the FDAs intransigence on stem cell treatments using adult stem cells has produced unintended consequences. Private clinics in the U.S. and outside the country are using adult stem cells for cosmetic surgery and treating other maladies like back pain with no clinical trials to prove their efficacy and safety.

Neuralstem ALS Stem Cell Trial Interim Results Reported in the Journal, STEM CELLS

Posted: March 28, 2012 at 5:34 pm

ROCKVILLE, Md., March 28, 2012 /PRNewswire/ --Neuralstem, Inc. (NYSE Amex: CUR) announced that safety results from the first 12 patients with amyotrophic lateral sclerosis (ALS or Lou Gehrig's disease) to receive its stem cells were reported online in the peer-reviewed publication, STEM CELLS, on March 13th. "Lumbar Intraspinal Injection of Neural Stem Cells in Patients with ALS: Results of a Phase I Trial in 12 Patients" (http://www.ncbi.nlm.nih.gov/pubmed/22415942.1) reports that one patient has shown improvement in his clinical status, even though researchers caution that the study was not designed to show efficacy. Additionally, there was no evidence of accelerated disease progression due to the intervention in any of the 12 patients, who were followed from 6-18 months after they were transplanted with the cells. All of the patients, who received transplants in the lumbar (lower back) region, tolerated the treatment without any long-term complications related to either the surgery or the cells.

(Logo: http://photos.prnewswire.com/prnh/20061221/DCTH007LOGO )

The 12 patients, part of the ongoing Phase I trial to evaluate the safety of Neuralstem's stem cells and transplantation procedure in patients with ALS, were the first in the world to receive intraspinal stem cell injections. Results from these patients were also were reported at the American Academy of Neurology Annual Meeting last September.

Based on a positive safety assessment, the trial has now been approved by the FDA to progress to transplanting ALS patients in the cervical (upper back) region of the spine, where the goal is to protect the motor neurons which affect respiratory function, and possibly prolong life. The fourteenth patient was transplanted earlier this month. All patients were treated at Emory University Hospital in Atlanta, Georgia.

"For these first 12 patients, we have met the objective of the Phase I trial, demonstrating safety for both the procedure of intraspinal injection and the presence of the neural stem cells in the spinal cords of ALS patients," said Jonathan Glass, MD, lead author of the publication. "We are encouraged by these results and have now advanced our trial to injections into the cervical spinal cord, targeting the motor neurons that control respiratory function." Dr. Glass is Professor of Neurology and Pathology at Emory University School of Medicine, as well as the Director of the Emory ALS Center.

"This important peer-reviewed publication reinforces our belief that we have demonstrated a safe, reproducible and robust route of administration into the spine for these spinal cord neural stem cells," said Eva Feldman, MD, PhD, Director of the A. Alfred Taubman Medical Research Institute and Director of Research of the ALS Clinic at the University of Michigan Health System. "The publication covers data up to 18 months out from the original surgery. However, we must be cautious in interpreting this data, as this trial was neither designed nor statistically powered to study efficacy." Dr. Feldman is senior author on the study, principal investigator (PI) of the ALS trial and serves as a consultant to Neuralstem as part of her University of Michigan activities.

"As this article points out, our experience in the lumbar spinal cord has been overwhelmingly positive," commented Karl Johe, PhD, study author and Neuralstem Chairman and Chief Scientific Officer. "We have already transplanted two patients in the cervical spinal cord, where we believe we can affect patients' lives the most by improving their breathing. We are in active discussions with the FDA to increase the number of cells and the number of injections as well."

"We wish to thank the teams at Michigan and Emory for the tireless efforts required to refine this breakthrough method of administration of our neural stem cells. We'd also like to thank the patients and families involved in the trial," said Richard Garr, Neuralstem CEO and President. "The progress we have made to date is both substantial, and a true team effort."

About the Study

Safety results were reported on the first 12 patients in an ongoing Phase I study to evaluate the safety of Neuralstem's spinal cord stem cells (HSSC's), as well as the transplantation technique, in the treatment of ALS (amyotrophic lateral sclerosis, or Lou Gehrig's disease).

Senior author Dr Irving Weissman, professor of pathology at Stanford, and colleagues, write about their success in treating bladder, brain, breast, colon, liver, ovarian, and prostate cancer tumors in this week's online ahead of print issue of the Proceedings of the National Academy of Sciences.

They say the antibody blocks a protein known as CD47, that sends "don't eat me" signals that cancer cells use to stop macrophages and other cells of the immune system from gobbling them up.

Anti-CD47 is the first antibody treatment to work against a variety of human solid tumors. The investigators said they are now eager to get started with phase 1 and phase 2 clinical trials in humans within the next two years.

The treatment also significantly reduced the ability of the tumors to spread (metastasize) to other parts of the mice's bodies, and in some cases, the animals appeared to be "cured".

Weissman, who directs the Institute of Stem Cell Biology and Regenerative Medicine and the Ludwig Center for Cancer Stem Cell Research and Medicine, both at Stanford, told the press their findings show "conclusively" that CD47 is a "a legitimate and promising target for human cancer therapy":
