Seeking superior stem cells: "New technique produces one hundred-fold increase in efficiency in reprogramming human cells --- Researchers from the Wellcome Trust Sanger Institute have today (10/10/2011) announced a new technique to reprogramme human cells, such as skin cells, into stem cells. Their process increases the efficiency of cell reprogramming by one hundred-fold and generates cells of a higher quality at a faster rate.
Until now cells have been reprogrammed using four specific regulatory proteins. By adding two further regulatory factors, Liu and co-workers brought about a dramatic improvement in the efficiency of reprogramming and the robustness of stem cell development. The new streamlined process produces cells that can grow more easily.
"This research is a milestone in human stem cells," explains Wei Wang, first author on the research from the Wellcome Trust Sanger Institute. "Our technique provides a foundation to unlock the full potential of stem cells.""
