Summary:
Investigators at the Massachusetts General Hospital (MGH) Center for Regenerative Medicine have confirmed that induced pluripotent stem cells (iPSCs) retain some characteristics of the cells from which they were derived, something that could both assist and impede potential clinical and research uses. In their report that will be published in Nature Biotechnology and has received early online release, the researchers also describe finding that these cellular "memories" fade and disappear as cell lines are cultured through successive generations.
