Effect of Rho-associated kinase inhibitor on cryopreservation of hES cells

ABSTRACT: After thawing, the mechanism of apoptosis advancing in human ES cells was invesitigated mainly by Gene conpath analysis. As time passed after thawing, nuclear fragmented cells increased more and more in cR-/mR- and cR+/mR-, but in cR+/mR+ and cR-/mR+, thawed cells formed cluster markedly, which was seen among three cell lines. Flow cytometry using TUNEL assay supported final colony formation ratio, which defined that such cell death was due to apoptosis. Gene map analysis 12 hours later after thawing of cR-/mR- showed activation of IL-1? & its receptor IL-1R and TGF-? & its receptor ACVR1C required for activation of caspase-8, initiation of caspase-8 and 10 and marked activation of ARHGDIB promoting actin reorganization comparing to cR+/mR+. Recovered cell lines in any condition did not
