Crystallization of the supercooled state is a disaster. (Tissue will freeze intracellularly, which is fatal). The thrust of current organ preservation research is actually to supercool all the way to deep sub-zero temperatures, thereby vitrifying tissue without any damaging crystal formation. *************************************************************************** Brian Wowk CryoCare Foundation 1-800-TOP-CARE President Human Cryopreservation Services http://www.cryocare.org/cryocare/ --------------------------------------------------------------------------- Rate This Message: http://www.cryonet.org/cgi-bin/rate.cgi?msg=8356
