Converting adult stem cells to embryonic-like stem cellsThe simple recipe researchers 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........Go to the Research news blog (Added on 2/6/2009 6:14:16 AM)
