    Enlarge Image New fate. Applying synthetic RNA for a muscle master-control gene turns embryonic cells into muscle cells. Credit: Warren et al., Cell Stem Cell, Advance Online Publication (2010) Four years ago, scientists took a major step toward overcoming the biggest ethical hurdle in stem cell research. Instead of using cells derived from embryos, researchers found a way to make adult cells behave as though they were embryonic. Simply inserting extra copies of four genes into these cells gave them the power to develop into almost any cell type in the body—a potential boon for studying and ultimately treating...

    Bioethics: A federal judge rules that the administration violated congressional intent when it lifted restrictions on federal funding for embryonic stem cell research. No, this will not usher in a new dark age. The ruling by U.S. District Judge Royce Lamberth was striking enough. Lamberth said that when President Obama lifted Bush administration restrictions on ESCR, he violated the Dickey-Wicker Amendment. First passed in 1996, and passed every year as part of the federal budget, Dickey-Wicker blocks federal funds for stem cell research in which human embryos are destroyed. Perhaps more striking is the press coverage of Lamberth's ruling. The...

    When scientists play politics with science, society and science both suffer, sometimes with life-threatening implications.  One recent example is Climategate, with revelations that leading global warming researchers played with the data, concealed and tried to suppress data that challenged their assertions and attempted to game the peer-review system.  And as a result of scientists caught playing politics with science, claims of man-made global warming have been met with growing skepticism. But a similar scenario has played out regarding human embryonic stem cell research (hESCR),  With the introduction of legislation to codify the Obama administration's rules expanding the federal role in...

    Norwegian scientists have developed a microfluidic platform to grow stem cells outside of the body in a controlled manner for a period of three weeks.  Stem cells from bone marrow are known as mesenchymal stem cells (MSCs) and like all adult stem cells they survive in specific microenvironments within the body, known as niches. But it's not so easy to grow them outside the body as they spread out as they grow which makes it difficult to control their microenvironment in vitro, as they tend to inhabit and block feeding channels.

    Scientists at the Swedish medical university Karolinska Institutet have shown how transplanted stem cells can connect with and rescue threatened neurons and brain tissue. The results point the way to new possible treatments for brain damage and neurodegenerative diseases. A possible strategy for treating neurodegenerative diseases is to transplant stem cells into the brain that prevent existing nerve cells from dying. The method has proved successful in different models, but the mechanisms behind it are still unknown. According to one hypothesis, the stem cells mature into fully-mature neurons that communicate with the threatened brain tissue; according to another, the stem...

    Stem cells have a unique ability: when they divide, they can either give rise to more stem cells, or to a variety of specialised cell types. In both mice and humans, a layer of cells at the base of the skin contains stem cells that can develop into the specialised cells in the layers above. Scientists at the European Molecular Biology Laboratory (EMBL) in Monterotondo, in collaboration with colleagues at the Centro de Investigaciones Energéticas, Medioambientales y Tecnologicas (CIEMAT) in Madrid, have discovered two proteins that control when and how these stem cells switch to being skin cells. The findings,...

All three patients were blind in one eye. The researchers extracted stem cells from their working eyes, cultured them in contact lenses for 10 days, and gave them to the patients. Within 10 to 14 days of use, the stem cells began recolonizing and repairing the cornea. Of the three patients, two were legally blind but can now read the big letters on an eye chart, while the third,...

    In a world-first breakthrough, University of New South Wales (UNSW) medical researchers have used stem cells cultured on a simple contact lens to restore sight to sufferers of blinding corneal disease. Sight was significantly improved within weeks of the procedure, which is simple, inexpensive and requires a minimal hospital stay. The research team from UNSW’s School of Medical Sciences harvested stem cells from patients’ own eyes to rehabilitate the damaged cornea. The stem cells were cultured on a common therapeutic contact lens which was then placed onto the damaged cornea for 10 days, during which the cells were able to...

    Robert Lanza is now reporting that his research group has produced induced Pluripotent Stem Cells (iPS) that are safe for use in humans. The website, Red Orbit, has provided a link to the original (.pdf)article. See the Time magazine news article, here. Lanza gives credit to the pioneering work of Shinya Yamanaka: Dr. Robert Lanza, chief scientific officer at Advanced Cell Technology (ACT), reported today in the journal Cell that his team has created stem cells using human skin cells and four proteins. The innovation builds on the breakthrough discovery in 2006 by Shinya Yamanaka, who similarly coaxed human skin...

    Research using adult stem cells has saved the life of a Texas boy suffering from sickle cell anemia.   Dallas-area residents Joe and Darlene Davis welcomed the news of a pregnancy and later the birth of their first son. Texas Alliance for Life recorded an interview with the couple. "I was very excited to find that I had a son -- but finding out that he had sickle cell anemia, as a nurse I knew there was going to be a lot of problems associated with that disease," Joe said. "The child can have strokes," Darlene also noted. "It can stunt his growth and...
  • New cancer-killing method found in stem cells, cells showing potential in cancer fight

    Genetically engineered stem cells from bone marrow showed promise as a potential new way to deliver a cancer-killing protein to tumors, British researchers said on Tuesday. Experiments in cell cultures and in mice showed the adult stem cells — a type known as mesenchymal stem cells — could home in on cancer cells and deliver a lethal protein that attacked only the cancer while sparing normal healthy tissue. “We’ve developed cells which specifically target cancer through the body and deliver an anti-cancer protein to where it is needed in a seek-and-destroy approach,” said Dr. Michael Loebinger of University College London,...

    TUESDAY, (HealthDay News) -- Injecting bone marrow cells into the heart's muscular wall restored blood flow to hearts with blocked arteries for which conventional treatments had proven ineffective, Dutch physicians have reported. "I think this is very good news for patients who are at the end of the line and have no options left," said Dr. Douwe E. Atsma, an interventional cardiologist at Leiden University Medical Center and an author of the study, which appears in the May 20 issue of the Journal of the American Medical Association. The 50 people in the study, 43 of them men, were experiencing...

    April 24, 2009 ( - A preliminary study on the use of stem cells obtained from a patient's own adipose tissue in the treatment of multiple sclerosis (MS) has shown promising results. The three case studies, described in BioMed Central's open access Journal of Translational Medicine support further clinical evaluation of what are known as stromal vascular fraction (SVF) cells in MS and other autoimmune conditions. Thomas Ichim, from Medistem Inc., and Dr. Boris Minev, from the Division of Neurosurgery, University of California San Diego, worked with a team of researchers to demonstrate the possible effectiveness of SVF cells in...

    Doctors ... removed the stem cells from the patient's bone marrow in the leg, then separated or purified the stem cells and intravenously returned them to the patient within a few hours. Because they are the patient's own stem cells, rejection was not an issue as is the case with embryonic stem cells. "Research shows that stem cells have an instinctive guidance system and migrate to the area of injury. While the stem cells do not produce new brain cells for this patient, they enhance the repair process in the brain and reduce damage," the doctors said in a press...

    ONDON, April 15 (Reuters) - A stem-cell repair technique that has already been used to fix hundreds of injured race horses is to be tested for the first time in people with damaged Achilles tendons. Privately owned British biotech firm MedCell Bioscience Ltd said on Wednesday it would start clinical tests within 12 months and planned to run a larger confirmatory study at several European hospitals in 2011. Patients will receive injections containing millions of their own stem cells, which have been extracted and multiplied up in a laboratory, and can regenerate new tissue to repair damaged regions.

    A team of UCSF researchers has for the first time used tiny molecules called microRNAs to help turn adult mouse cells back to their embryonic state. These reprogrammed cells are pluripotent, meaning that, like embryonic stem cells, they have the capacity to become any cell type in the body. The findings suggest that scientists will soon be able to replace retroviruses and even genes currently used in laboratory experiments to induce pluripotency in adult cells. This would make potential stem cell-based therapies safer by eliminating the risks posed to humans by these DNA-based methods, including alteration of the genome and...

    Washington, DC ( -- A recent appearance by Dr. Mehmet Oz, a cardiovascular surgeon at Columbia University and a regular on Oprah Winfrey's popular eponymous television program, is generating buzz within pro-life circles. During the program, Oz told Americans the truth about embryonic stem cell research.Oz made it clear that the "stem cell debate is dead" mostly in part because embryonic stem cells have yet to catch up to their adult stem cell and iPS cell counterparts.The comments are drawing interest because Oz made them in front of the iconic television personality and embryonic stem cell research advocate Michael J....
