Vitrification is a promising approach for cryopreservation of adherent cells because it allows complete avoidance of ice formation. However, high cryoprotectant (CPA) concentrations are required to prevent freezing, and exposure to high CPA concentrations increases the risk of osmotic and toxic damage. Although cell membrane transport modeling can be used...
BACKGROUND: Simple and effective cryopreservation of human oocytes would have
an enormous impact on the financial and ethical constraints of human assisted
reproduction. Recently, studies have demonstrated the potential for cryopreservation
in an ice-free glassy state by equilibrating oocytes with high concentrations of
cryoprotectants (CPAs) and rapidly cooling to liquid...
Ice-free cryopreservation, known as vitrification, is an appealing approach for banking of adherent cells and tissues because it prevents dissociation and morphological damage that may result from ice crystal formation. However, current vitrification methods are often limited by the cytotoxicity of the concentrated cryoprotective agent (CPA) solutions that are required...
