Four Steps for Validating Stem Cells

July 15, 2016

(Euekalert) – It has been difficult to generate human embryonic stem cells at the earliest stage of pluripotency, in what is named “ground” or “naïve” state, whereas this is readily done with mouse cells. The labs of Rudolf Jaenisch at MIT, Joe Ecker at the Salk Institute, and Didier Trono at EPFL have now developed a four-step process for determining accurate signatures of human embryonic stem cells and relating them to precise developmental stages. The work, a first for human embryonic stem cells, is published in Cell Stem Cell.
