>Small Town Hospital Collects Cord Blood for Texas Public Banks
>I was so happy to hear that my local hospital is now one of the hospitals that collects cord blood for the public banks. The cells from cord blood are rich in adult stem cells that can be used to replace the bone marrow of children with blood disorders and for treatment of all sorts … Continue reading
Political news in Nature Reports
Rather than science news, Nature Reports focuses on the political (I believe this is available without subscription, but let me know if you need a copy and can’t access it): News Feature Nature Reports Stem Cells Published online: 17 October 2007 Scientific definition by political request (by) Monya Baker The NIH must set criteria for … Continue reading
The Politics of Embryonic Stem Cells: Gearhart “pressures” Atala
I was able to attend the “Understanding Stem Cells: Science and Policy” lecture at the Koshland Science Museum, the museum of the National Academies of Sciences, in Washington, DC last week where I heard Jonathan Moreno, PhD, – the ethicist who works for and advances the American Center for Progress and Dr. John Gearhart, Director … Continue reading
>New President of California Stem Cell Institute
>Alan Trounson, PhD, the researcher responsible for the first in vitro (IVF) birth in Australia, who once had to apologize for misleading the Australian Parliament after showing them a video that he claimed showed a mouse that walked after human embryonic stem cell treatment for spinal cord injury (in fact, they were fetal cells from … Continue reading
>Review: What we know about stem cells
>The Journal, Stem Cells, has published a free open access article about those cells that become the different blood cells, including red blood cells, white blood cells and platelets, entitled “Concise Review: Hematopoietic Stem Cells and Tissue Stem Cells: Current Concepts and Unanswered Questions” by Donald Metcalf, MD, of Australia. An interesting point from this … Continue reading
>Embryonic stem cells for chemical weapons detectors?
>First, I want to say admit that this whole subject gives me the creeps. As an avid science fiction reader, I was surprised to find that I am not ready for disembodied human neural cells sitting around – functioning – in machines. I’m certainly not willing for anymore human embryos to be destroyed for such … Continue reading
Rao: Adult Stem Cells “soon to be on the market”
The journal Stem Cells has published an Open-Access review by the former NIH director, Mahendra Rao, MD, PhD, covering last month’s “Adult Mesenchymal Stem Cells in Regenerative Medicine Conference” at the National Center for Regenerative Medicine in Ohio. Another review with summaries of some of the individual talks as well as the history of the … Continue reading
>Stem Cells in Tendons (Plus some education)
>The National Institutes of Health (NIH) reported last week that scientists have isolated stem cells from tendons which help in the growth and repair of those structures. The abstract of the peer-reviewed report, “Identification of tendon stem/progenitor cells and the role of the extracellular matrix in their niche,” is curently available at Nature Medicine at … Continue reading
>Confirmation: Adult Cells Reprogrammed to Embryonic Stem Cells
>Last year, we read, and blogged about experiments by Drs. Kazutoshi Takahashi and Shinya Yamanaka of Kyoto University in Japan demonstrating that (adult) mouse fibroblasts could be reprogrammed to become embryonic stem cells in hopes of being able to one day develop truly “patient specific” stem cells made from the person’s own adult stem cells. … Continue reading
>Texas Researchers: Prostate Pluripotential Stem Cells
>Researchers Dr. Liping Tang from the Bioengineering Department at University of Texas at Arlington, and Dr. Victor K. Lin of the Department of Urology at UT Southwestern (Dallas, Texas) have published a paper describing pluripotent adult stem cells from prostate tissue. Tissue cultures as well as biochemical markers show that the cells harvested from men … Continue reading
