Scientists Create Therapy-Grade Stem Cells Using New Cocktail to Reprogram Adult Cells

September 17, 2014

(Eurekalert) – Now researchers at the Hebrew University of Jerusalem have developed a new cocktail of reprogramming factors that produce high-quality iPSCs. Dr. Yosef Buganim, at the Institute for Medical Research Israel-Canada in the Hebrew University’s Faculty of Medicine, worked with scientists at the lab of Whitehead Institute founding member Rudolf Jaenisch, a professor of biology at MIT. The researchers reasoned that changing the reprogramming factors could reprogram the adult cells in a more controlled way and yield high-quality iPSCs. Working with mouse cells, Dr. Buganim and research scientist Styliani Markoulaki used bioinformatic analysis to design a new cocktail of reprogramming factors (Sall4, Nanog, Esrrb, and Lin28, known collectively as SNEL).
