Unraveling Subcellular and Ultrastructural Changes During Vitrification of Human Spermatozoa: Effect of a Mitochondria-Targeted Antioxidant and a Permeable Cryoprotectant

open access: yesFrontiers in Cell and Developmental Biology, 2021
Mitochondria-targeted antioxidants have great potential to counterbalance the generated reactive oxygen species (ROS) because they cross the inner membrane of the mitochondria. Still, their use was not reported in vitrified human spermatozoa.

Vitrification of Pronuclear Zygotes Perturbs Porcine Zygotic Genome Activation

open access: yesAnimals, 2022
Zygotic genome activation (ZGA) plays an essential role in early embryonic development. Vitrification is a common assisted reproductive technology that frequently reduces the developmental competence of embryos.

Vitrification Solutions for Plant Cryopreservation: Modification and Properties

open access: yesPlants, 2021
Many plants cannot vitrify themselves because they lack glassy state-inducing substances and/or have high water content. Therefore, cryoprotectants are used to induce vitrification.

Cryopreservation of Brazilian green dwarf coconut plumules by droplet-vitrification

open access: yes, 2020
: This study evaluated the effect of vitrification solutions and exposure time on the cryopreservation of Brazilian green dwarf coconut plumules (BGD) using the droplet vitrification technique. Explants were excised from BGD mature fruits from the Active

In vitro application of Ceratonia siliqua improved sperm parameters and chromatin quality after vitrifacation in normozoospermic aged men

open access: yesMiddle East Fertility Society Journal, 2019
Background Vitrification is the main technique in the assisted reproductive technique (ART) labs. Sperm vitrification exposes sperm to damage. The aim of the present study was to evaluate the in vitro effect of Ceratonia siliqua (C.

Successful production of offspring derived from mouse zygotes vitrified with carboxylated ε-poly-L-lysine and polyvinyl alcohol without serum

open access: yesThe Journal of Reproduction and Development, 2022
The vitrification of zygotes is important for their use as donors for generating genome-edited mice. We previously reported the successful vitrification of mouse zygotes using carboxylated ε-poly-L-lysine (COOH-PLL).

Evaluation of different factors affecting the efficiency of oocytes cryopreservation in the bovine model [PDF]

open access: yes, 2011
Interest in oocyte cryopreservation has recently increased. Cattle oocytes are sensitive to low temperatures, and despite the efforts of numerous research groups cryopreservation of oocytes remains a difficult task.
