Human Blastocyst Biopsy and Vitrification.

Journal of Visualized Experiments, 2019
Blastocyst biopsy is performed to obtain a reliable genetic diagnosis during IVF cycles with preimplantation genetic testing. Then, the ideal workflow entails a safe and efficient vitrification protocol, due to the turnaround time of the diagnostic ...

The effects of vitrification on oocyte quality

Biology of Reproduction, 2021
Vitrification, is an ultra-rapid, manual cooling process that produces glass-like (ice crystal-free) solidification. Water is prevented from forming intercellular and intracellular ice crystals during cooling as a result of oocyte dehydration and the use

Effect of vitrification at different meiotic stages on epigenetic characteristics of bovine oocytes and subsequently developing embryos.

Animal science journal = Nihon chikusan Gakkaiho, 2021
Vitrification by the Cryotop method is frequently used for bovine oocyte cryopreservation. Nevertheless, vitrified oocytes still have reduced developmental competency compared with fresh counterparts. The objective of this study was to compare the effect

Review of non-permeating cryoprotectants as supplements for vitrification of mammalian tissues.

Cryobiology, 2020
Vitrification of mammalian tissues is important in the areas of human assisted reproduction, animal reproduction, and regenerative medicine. Non-permeating cryoprotectants (CPAs), particularly sucrose, are increasingly used in conjunction with permeating
