Improved viability of freeze-thawed embryonic stem cells after exposure to glutathione

Adding a potent antioxidant, glutathione (GSH), to a cryoprotective solution consisting of dimethyl sulfoxide and ethylene glycol and/or postthaw culture medium significantly improved the postthaw viability of mouse embryonic stem cells. This effect, which was caused by a decrease in reactive oxygen species, was only induced by exposure of embryonic stem cells during cryopreservation. (Fertil Steril (R) 2010;94:2409-12.
