Stem Cells Created from Adults’ Cells
For the first time, researchers have successfullycreated stem cells from the skin cells of adults. This is considered the first step in developing patient-specific cells lines to treat diseases like heart failure, Parkinson’s, multiple sclerosis, and vision loss, but it is also the first step inhuman reproductive cloning, an issue fraught with ethical dilemmas. To create the stem cells, researchers fused a grown skin cell with an ovum whose DNA had been removed. The resulting embryo contains an inner lining of pluripotent stem cells. Of 39 attempts to create stem cells from adult cells, the researchers succeeded only once for each of their two skin cell donors. More… Discuss
