The largest national stem cell study for heart disease showed the first evidence that transplanting a potent form of adult stem cells into the heart muscle of subjects with severe angina results in less pain and an improved ability to walk. The transplant subjects also experienced fewer deaths than those who didn't receive stem cells. http://www.physorg.com/news177704058.html Medicine & Health Tue, 17 Nov 2009 18:30:02 EST news177704058 Researchers from North Carolina State University have identified a gene that tells embryonic stem cells in the brain when to stop producing nerve cells called neurons. The research is a significant advance in understanding the development of the nervous system, which is essential to addressing conditions such as Parkinson's disease, Alzheimer's disease and other neurological disorders. http://www.physorg.com/news177678975.html Biology Tue, 17 Nov 2009 11:30:05 EST news177678975 Researchers at the University of Illinois at Chicago College of Medicine have shown that adult stem cells from bone marrow can prevent acute lung injury in a mouse model of the disease. http://www.physorg.com/news175964175.html Medicine & Health Wed, 28 Oct 2009 15:57:33 EST news175964175 A new type of stem cell discovered in the prostate of adult mice can be a source of prostate cancer, according to a new study by researchers at the Herbert Irving Comprehensive Cancer Center at Columbia University Medical Center and NewYork-Presbyterian Hospital. http://www.physorg.com/news171721946.html Medicine & Health Wed, 09 Sep 2009 14:10:01 EST news171721946 (PhysOrg.com) -- Using new genetic tools, Cornell researchers have found that some stem cells in mice behave dramatically different than in fruit flies, where most of the pioneering stem cell work has been conducted. The findings could have important implications for understanding how some cancers might be initiated, say the researchers. http://www.physorg.com/news169480057.html Biology Fri, 14 Aug 2009 15:40:07 EST news169480057 University of Florida researchers were able to program bone marrow stem cells to repair damaged retinas in mice, suggesting a potential treatment for one of the most common causes of vision loss in older people. http://www.physorg.com/news168257942.html Medicine & Health Fri, 31 Jul 2009 11:23:05 EST news168257942 (PhysOrg.com) -- Johns Hopkins biomedical engineering students have demonstrated a practical way to embed a patient`s own adult stem cells in the surgical thread that doctors use to repair serious orthopedic injuries such as ruptured tendons. The goal, the students said, is to enhance healing and reduce the likelihood of re-injury without changing the surgical procedure itself. http://www.physorg.com/news167326190.html Medicine & Health Mon, 20 Jul 2009 18:30:01 EST news167326190 Preliminary data presented on March 28 as a late-breaking abstract at the American College of Cardiology's 58th annual scientific session from the largest CD34+ adult stem cell study for heart disease has shown the first evidence that delivering a potent form of autologous (from the patient) adult stem cells into the heart muscle of patients with severe angina may result in less pain and improved exercise tolerance. http://www.physorg.com/news157624724.html Medicine & Health Mon, 30 Mar 2009 09:39:04 EST news157624724 More than five years ago, Dr. Lawrence C.B.

The potential of using these cells to repair or replace damaged tissue holds great promise for cancer therapies and regenerative medicine. However, the question that must first be answered is what determines the ultimate fate of a stem or progenitor cell? A team of researchers led by Berkeley Lab's Mark LaBarge and Mina Bissell appear to be well on the road to finding out. http://www.physorg.com/news154954632.html Biology Fri, 27 Feb 2009 10:57:50 EST news154954632 Researchers in the laboratory of Samuel I. Stupp at Northwestern University have an interesting approach for tackling some major health problems: gather raw materials and then let them self-assemble into structures that can address a multitude of medical needs. http://www.physorg.com/news153832994.html Nanotechnology Sat, 14 Feb 2009 11:23:55 EST news153832994 A quadriplegic since she was 14, Jessica Grimm learned long ago how to work around her body's limitations. She lives alone, uses a computer, has a job, even drives a car. But the Arlington, Texas, student must rely on a coterie of assistants to help her dress, cook and get through each day. http://www.physorg.com/news153377258.html Medicine & Health Mon, 09 Feb 2009 05:46:16 EST news153377258 The simple recipe scientists earlier discovered for making adult stem cells behave like embryonic-like stem cells just got even simpler. A new report in the February 6th issue of the journal Cell, a Cell Press publication, shows for the first time that neural stem cells taken from adult mice can take on the characteristics of embryonic stem cells with the addition of a single transcription factor. Transcription factors are genes that control the activity of other genes. http://www.physorg.com/news153059473.html Biology Thu, 05 Feb 2009 12:31:44 EST news153059473 Research using a mouse model of human leukemia has provided critical insight into the genetic factors related to the generation and maintenance of myeloid leukemia stem cells. The study, published by Cell Press in the February 6th issue of the journal Cell Stem Cell, is likely to have a profound impact on the future design of therapeutic approaches targeted against cancer stem cells. http://www.physorg.com/news153059231.html Biology Thu, 05 Feb 2009 12:27:42 EST news153059231 Much to the dismay of patients and physicians, cancer stem cells - tiny powerhouses that generate and maintain tumor growth in many types of cancers - are relatively resistant to the ionizing radiation often used as therapy for these conditions. Part of the reason, say researchers at Stanford University School of Medicine, is the presence of a protective pathway meant to shield normal stem cells from DNA damage. When the researchers blocked this pathway, the cells became more susceptible to radiation. http://www.physorg.com/news152977118.html Medicine & Health Wed, 04 Feb 2009 13:39:16 EST news152977118 (PhysOrg.com) -- Researchers have achieved a feat drug developers had thought difficult, if not impossible, discovering a compound that blocks the functioning of a key developmental protein by binding to an `undruggable` target - an advance that may provide a new avenue to fight skin, pancreatic, prostate, and other cancers. http://www.physorg.com/news151594160.html Biology Mon, 19 Jan 2009 13:29:57 EST news151594160 The first demonstration that a single adult stem cell can self-renew in a mammal was reported at the American Society for Cell Biology (ASCB) 48th Annual Meeting, Dec. 13-17, 2008 in San Francisco. http://www.physorg.com/news148484867.html Biology Sun, 14 Dec 2008 13:47:47 EST news148484867 (PhysOrg.com) -- The first tissue-engineered trachea (windpipe), utilising the patient's own stem cells, has been successfully transplanted into a young woman with a failing airway. The bioengineered trachea immediately provided the patient with a normally functioning airway, thereby saving her life. http://www.physorg.com/news146297595.html Medicine & Health Wed, 19 Nov 2008 06:13:15 EST news146297595 Researchers at the Yerkes National Primate Research Center, Emory University, have discovered dental pulp stem cells can stimulate growth and generation of several types of neural cells.

In fact, they're willing to pass them along. Using the molecular equivalent of a tattoo on DNA that adult stem cells (ASC) pass to their "daughter" cells in combination with gene expression profiles, University of Utah researchers have identified two early steps in adult stem cell differentiation -the process that determines whether cells will form muscle, neurons, skin, etc., in people and animals. http://www.physorg.com/news140266575.html Biology Wed, 10 Sep 2008 11:56:15 EST news140266575
