Several Sierra Sciences scientists, including Dr. Laura Briggs and Dr. Bill Andrews, recently collaborated with BioTime on a scientific paper, "Spontaneous reversal of the developmental aging of normal human cells following transcriptional reprogramming" which was published in the May 2010 issue of Regenerative Medicine.

The research suggests that, in addition to the differentiation process, cellular aging in iPS cells can be reversed. iPS cells that had sufficient levels of telomerase made it possible for these cells to become young again-resembling cells at the beginning of the human life cycle.
