Ultrastructure of immature and mature human oocytes after cryotop vitrification
In vitro maturation of vitrified immature germinal vesicle (GV) oocytes is a promising fertility preservation option. We analyzed the ultrastructure of human GV oocytes after Cryotop vitrification (GVv) and compared it with fresh GV (GVc), fresh mature metaphase II (MIIc) and Cryotop-vitrified mature (MIIv) oocytes. By phase contrast microscopy and light microscopy, the oolemmal and cytoplasmic...
متن کاملEfficient vitrification of mouse embryos using the Kitasato Vitrification System as a novel vitrification device
BACKGROUND Currently, the cryopreservation of embryos and oocytes is essential for assisted reproductive technology (ART) laboratories worldwide. This study aimed to evaluate the efficacy of the Kitasato Vitrification System (KVS) as a vitrification device for the cryopreservation of mouse embryos to determine whether this novel device can be adapted to the field of ART. METHODS In Experiment...
متن کاملEmbryo vitrification using a novel semi-automated closed system yields in vitro outcomes equivalent to the manual Cryotop method.
STUDY QUESTION Can the equilibration steps prior to embryo vitrification be automated? SUMMARY ANSWER We have developed the 'Gavi' system which automatically performs equilibration steps before closed system vitrification on up to four embryos at a time and gives in vitro outcomes equivalent to the manual Cryotop method. WHAT IS KNOWN ALREADY Embryo cryopreservation is an essential componen...
متن کاملVitrification of isolated mice blastomeres using a closed loading device
Isolated blastomeres obtained by embryo biopsy serve mainly for preimplantation genetic screening. Blastomeres are undifferentiated embryonic cells that include all the embryo genetic information. A lot of developing technologies may benefit by the efficient cryopreservation of blastomeres for future potential use, especially for stem cell culture and differentiation control. We are hereby repo...
متن کاملVitrification of immature feline oocytes with a commercial kit for bovine embryo vitrification.
The aim of this study was to evaluate the suitability of a commercial kit for bovine embryo vitrification for cryopreserving cat oocytes and to evaluate comparatively the effects of its use with slow freezing procedure on cryotolerance in terms of morphology and oocyte resumption of meiosis. Germinal vesicle stage oocytes isolated from cat ovaries were either vitrified (n = 72) using a vitrific...
