Molecular Differences Found Between Embryonic Stem Cells And Reprogrammed Skin Cells

ScienceDaily for July 3, 2009 reported on differences between embryonic stem cells and reprogrammed skin cells.

The data from the study suggest that embryonic stem cells and the reprogrammed cells, known as induced pluripotent stem (iPS) cells, have overlapping but still distinct gene expression signatures. The differing signatures were evident regardless of where the cell lines were generated, the methods by which they were derived or the species from which they were isolated, said Bill Lowry, a researcher with the Broad Stem Cell Research Center and a study author.
