How long can the stem cells be stored for?

Scientists have determined that all cell activity stops once the cells are frozen and stored at cryogenic temperatures. There is no potential for further damage because there is no molecular movement meaning the cells can be stored for extended amounts of time without compromising their integrity.

Currently cord blood stem cells do not have a use-by date. Published research suggests that there is no cell degeneration after 30 years of cryopreservation. Comparatively, bone marrow and other human tissues and cells have been stored for decades and have stayed viable. There is no reason to believe that the same would not be true for cord blood and tissue stem cells.
