DNA damage in cumulus cells generated after the vitrification of in vitro matured porcine oocytes and its impact on fertilization and embryo development

Porcine Health Management, 2021
Background The evaluation of the DNA damage generated in cumulus cells after mature cumulus-oocyte complexes vitrification can be considered as an indicator of oocyte quality since these cells play important roles in oocyte developmental competence ...

Cryopreservation of rye protoplasts by vitrification [PDF]

Cryobiology, 1989
A procedure has been developed for the vitrification of mesophyll protoplasts isolated from leaves of nonacclimated (NA) and cold-acclimated (ACC) winter rye seedlings (Secale cereale L. cv Puma). The procedure involves (a) equilibration (loading) of the protoplasts with an intermediate concentration (1.5, 1.75, or 2.0 molar) of ethylene glycol (EG) at

Hyperactive ice‐binding proteins stabilize cell membranes and improve resistance to dehydration stress in Caenorhabditis elegans

FEBS Open Bio, EarlyView.
TisIBP8, a fungal‐derived hyperactive ice‐binding protein, helps Caenorhabditis elegans survive dehydration. It localizes near cell membranes, reduces cell damage, and helps maintain membrane structure during drying. These results suggest that ice‐binding proteins can protect cells from dehydration stress as well as freezing stress.
