Although chemotherapy is used to kill cancer cells, it can also have a strong toxic effect on normal cells such as bone marrow and blood cells, often limiting the ability to use and manage the chemotherapy treatment. Researchers at Fred Hutchinson Cancer Research Center reported at today's annual meeting of the American Society of Gene and Cell Therapy in Seattle that one possible approach to reduce this toxic effect on bone marrow cells is to modify the cells with a gene that makes them resistant to chemotherapy. http://medicalxpress.com/news/2011-05-gene-modified-stem-cells-bone-marrow.html Cancer Sat, 21 May 2011 05:36:52 EST news225174980 If pending clinical trials prove successful, a new discovery published in The FASEB Journal could represent a major scientific leap toward human tissue regeneration and engineering. In a research report appearing online, Yale scientists provide evidence to support a major paradigm shift in this specialty area from the idea that cells added to a graft before implantation are the building blocks of tissue, to a new belief that engineered tissue constructs can actually induce or augment the body's own reparative mechanisms, including complex tissue regeneration. http://medicalxpress.com/news/2011-05-scientists-method-human-tissue-regeneration.html Medical research Thu, 12 May 2011 16:32:51 EST news224436750
