Brain Is Command Center for Aging | The Scientist Magazine®
But, what and when are we going to do about it? Hurry! Inflammation in the hypothalamus may underlie aging of the entire body, according to a study published today (May 1) in Nature. Over-activation of the inflammatory protein nuclear factor kB (NF-κB) in the brain region leads to a number of aging-related changes in mice, … Continue reading
Distinct niches in bone marrow nurture blood stem cells | Science Codex
The future of stem cell research: determine which conditions make the right stem cells in the body work the way we want them to, using stimulating factors for the good and suppressing the bad ones that cause cancer. “What we found was rather surprising,” Link says. “There’s not just one niche for developing blood cells … Continue reading
Scientists Explore (Adult) Stem Cells to Treat Diabetic Blindness
Great news about ethical treatment for a common complication of diabetes, from the Voice of America: Stitt, who directs the Queen’s University Center for Vision and Vascular Science, is participating in a European-led study called Repair of Diabetic Damage by Stromal Cell Administration (REDDSTAR). Researchers from the U.S., Northern Ireland, Germany, the Netherlands, Denmark and … Continue reading
High-priced mice for science at Texas A&M
This article from the Texas A&M newspaper describes the medical research with “knockout” mice, or mice that have a specific gene turned off. The University’s Texas Institute of Genomic Medicine , part of the College of Veterinary Medicine and Biomedical Sciences specializes in developing knockout mice strains using embryonic stem cells from mice embryos, which … Continue reading
New Class of Stem Cell-Like Cells Discovered in Spinal Cord Offers Possibilities for… — SEATTLE, Sept. 15, 2011 /PRNewswire/ —
This is exciting, although preliminary, research results. These researchers used what is known about stem cells to look for existing cells in the spinal cord. The genes that “switch on and off” are now known for quite a few stem cell lines and they are matched against all the cell genomes that we have in … Continue reading
Ethical dilemma in fetal stem cell research – UK stroke study
“The world’s first clinical trial of brain stem cells to treat stroke has recorded no adverse effects to date, BBC News has reported. The BBC website reports that research using stem cells to treat strokes “is set to move to its next phase” after independent assessors approved continuation of the trial of the experimental treatment. … Continue reading
Human-animal embryos don’t work for stem cell production
The New Scientist has a good review article that explains a new research report from Robert Lanza of Advanced Cell Technology, that attempts with “thousands” of embryos created by placing human DNA into the oocytes or eggs of animals have failed to produce stem cells. NatureNews, the news arm of the journal, Nature discusses the … Continue reading
“Tea-bag” Adult Stem Cell Treatment for Stroke
British researchers report an amazing recovery for a 49 year old man who suffered a hemorrhagic stroke on October 15, 2008. The researchers at the company, “Biocompatibles,” used adult stem cells from a healthy donor. The cells had been engineered to cause them to produce a protein that helps prevent “programmed” cell death (even after … Continue reading
We need sharing, not eggs or embryos!
From WebMD: “We don’t need any eggs or embryos at all,” says Shinya Yamanaka, MD, a professor at the Institute for Frontier Medical Sciences in Kyoto, Japan. Yamanaka describes his lab’s early successes in mice creating stem cells from adult cells. His research involves isolating two dozen chemicals that give embryonic stem cells their ability … Continue reading
McGee: Embryo research equals physician assisted suicide
Glenn McGee, one of the editors, pseudoeditors and bloggers over at the American Journal of Bioethics blog, Blog.Bioethics.net, posted a portion of his column, “The Kavorkianization of Dolly” for The Scientist. Subscription is required for The Scientist, but you can read part of the snide column on the blog.bioethics.net site (or here). It may be … Continue reading
