In Vitro Growth and Maturation of Vitrified-Warmed Bovine Oocytes Collected from Early Antral Follicles
Cryopreservation of growing oocytes enriches the choice of timing and location of artificial embryo production. However, completion of oocyte growth after warming is crucial when using such cryopreserved oocytes. Our research objective was to develop a sequential system that incorporates cryopreservation of growing bovine oocytes and their subsequent in vitro growth. Oocyte-granulosa cell compl...
متن کاملP-36: Addition of Zinc in The Vitrification Medium Improves In Vitro Maturation of Oocytes Derived from Vitrified-Warmed Follicles
Background Follicle cryopreservation has been proposed as an alternative fertility preservation option. Follicles can be cryopreserved in intact ovarian tissue pieces or after isolation of individual follicles from the fresh ovarian tissue using enzymatic or mechanical techniques. Researchers have used different cryoprotectants and various techniques to improve cryopreservation. It is plausible...
متن کاملThe impact of alpha lipoic acid on developmental competence of mouse vitrified pre-antral follicles in comparison to those isolated from vitrified ovaries
BACKGROUND Cryopreservation of ovarian tissues and pre-antral follicles is a promising prospect for preservation of women fertility. OBJECTIVE The aim of this study was to evaluate the in vitro developmental competence of mouse vitrified pre-antral follicles in comparison to isolated pre-antral follicles derived from vitrified ovaries in the presence of alpha lipoic acid (ALA). MATERIALS AN...
متن کاملComparison of the cryo-tolerance of vitrified gorgonian oocytes
Coral reefs have been declining considerably in recent years because of changes to the environment and climate. The cryopreservation of coral gametes is an essential alternative method that yields immense success in preserving corals. This study focuses on developing vitrification techniques for Junceella fragilis and Ellisella robusta oocytes, and presents a comparison on the cryotolerance of ...
متن کاملP-118: Developmental Competence of Ovine Embryos Derived from Frozen Oocytes Co-Cultured with Embryos Derived from Fresh Oocytes
Background: Currently, a limited number of studies have been done on the vitrification of small ruminant oocytes, especially in sheep, where poor developmental rates are obtained following immature and mature oocyte vitrification. Poor ovine oocyte cryopreservation could attribute to the damage to enzymes which has role in metabolic pathways. Therefore, production of cytokines and growth factor...
