It was an exciting moment. The ability of such cells to morph into any other sort of cell suggested that worn-out or damaged tissues might be repaired, and diseases thus treated--a technique that has come to be known as regenerative medicine. Since then progress has been erratic and (because of the cells' origins) controversial. But, as two new papers prove, progress there has indeed been. This week's Lancet published results from a clinical trial that used embryonic stem cells in people. Steven Schwartz of the University of California, Los Angeles, claims some success in treating a different problem: blindness. His research, sponsored by Advanced Cell Technology, a company based in Massachusetts, involved two patients. Dr Schwartz and his team coaxed embryonic stem cells to become retinal pigment epithelium--tissue which supports the rod and cone cells that actually respond to light--then injected 50,000 of them into one eye of each patient, with the hope that they would bolster the natural supply of these cells. The result was a qualified success. Opini Anda Klik untuk menuliskan opini Anda tentang koleksi ini! Kembali
