Several steps are potentially mutagenic, such as exposure to high cytosolic concentrations of ethylene glycol, and the extreme dehydration that is a requisite for vitrification. A good cryoprotectant, then, would be one which causes the bulk solvent to go through its density change long before vitrification occurs. Effective cryopreservation of human embryonic stem cells by the open pulled straw vitrification method. The embryos were compared with in vivo blastocysts derived from the uterus on day 5 of pregnancy as regards their response to vitrification treatment. Vitrification secures the waste for several thousands of years and would be used in conjunction with a deep repository disposal. Vitrification is a method in which not only cells but the entire solution is solidified without the crystallization of ice. As mentioned above, lattice repacking and solvent transport both require solvent rearrangement, which is impossible after solvent vitrification. The in vitro blastocysts seemed more susceptible to vitrification solution per se than to the vitrification-warming treatments. No difference was observed between the two vitrification methods. To summarize, vitrification of the intermembrane layer causes the membranes to tend to remain in the phase they were in at the time of vitrification. In vivo blastocysts were more severely injured by vitrification and warming procedures than by exposure to vitrification solution. Also, the relative abundance of survivin and caspase-3 expression did not differ significantly between the two vitrification methods. Immediately after vitrification and warming rabbit embryos displayed severe subcellular damage and the increased presence of unevenly shaped nuclei with immature nucleoli.

Adding cryoprotectant inhibits ice formation and promotes vitrification, but more importantly alters the amount of expansion. However, both vitrification methods resulted in blastocysts with a significantly higher apoptotic index than that found in fresh blastocysts (non-frozen controls). In embryo cryopreservation, vitrification has advantages over slow freezing methods. If vitrification occurs between fluid membranes (small solutes, a2), the presence of the glass will hinder the transition to the gel phase. Thus, the best cooling rate may be the slowest rate that causes vitrification and prevents ice formation.

All-round vitrification method for human oocytes and embryos (abstract). Vitrification of immature porcine oocytes: effects of lipid droplets, temperature, cytoskeleton, and addition and removal of cryoprotectant. The size of the glass-forming solute is an important consideration that has led to further confusion and controversy about the proposed role of vitrification on membrane stabilization in desiccated systems. In the case of the excluded large solutes, vitrification will have little direct effect on the membranes because vitrification takes place in bulk volumes of solution. Cryopreservation of animal and human embryos by vitrification. The critical role of sugars in promoting the state of intracellular vitrification during drying, and hence the condition of low molecular and free radical mobility, remains in favour. Vitrification of mouse oocytes results in aneuploid zygotes and malformed fetuses. Vitrification will have a significant effect on membrane phase behaviour only if the glass forms between the membranes, or between a membrane and other hydrophilic ultrastructural elements.
