The Quest for a Cure: Stem Cells' Potential for 10 Vexing IllnesssWith President Barack Obama's recent lifting of the ban on federal funding for embryonic stem cell research, scientists now have new prospects for developing medical treatments. Excitement over the embryonic cells comes from their remarkable ability, as biological blank slates, to become virtually any of the body's cell types. Many observers believe the president's move will accelerate the hunt for cures for some of our most vexing diseases. |
Adult Stem Cell Breakthrough: First Tissue-engineered Trachea Successfully TransplantedThe 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. |
Breakthrough in Medicine: Bone Marrow Transplant May Cure HIVA German doctor says one of his patients, who suffered from leukaemia and was infected with the immunodeficiency virus that causes AIDS, appears to have been cured of AIDS by a bone marrow transplant from a donor who had a genetic mutation known to help the body resists AIDS infection. |
Foreign stem cell clinics boomingEvery three months, David Martin, a quadriplegic, returns to a small clinic in the Russian capital for therapy he cannot legally get back home in Kalamazoo, Mich.: injections of stem cells taken from his own body, at a cost of $12,000 per visit. |
Adult Stem Cells Help Those With Immune Disorders, Heart DiseaseTreatment with adult stem cells harvested from blood or bone marrow may benefit some patients with certain kinds of cardiovascular disorders and autoimmune diseases, a new U.S. analysis shows. |
By modifying a stem cell's surface, researchers can steer cells where needed11 Feb 2008. Now it appears that even stem cells can come with GPS. In a groundbreaking study, Robert Sackstein, MD, PhD, and colleagues in the Department of Dermatology at the Biomedical Research Institute at Brigham and Women’s Hospital (BWH) harmlessly modified the surface of human mesenchymal stem cells (a type of adult stem cell that is the precursor of bone forming cells called osteoblasts), which directed the cells through the bloodstream into bone, where they matured into new bone cells. These findings will appear in the February print issue of Nature Medicine and on the journal’s website. |
Researcher transplants stem cells to try to save patients' legs2008 FEB 4 -- A Northwestern University Feinberg School of Medicine researcher has launched the first U.S. trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation in their legs. |
Finnish patient gets new jaw from own stem cellsHELSINKI (Reuters) - Scientists in Finland said they had replaced a 65-year-old patient's upper jaw with a bone transplant cultivated from stem cells isolated from his own fatty tissue and grown inside his abdomen. |
