Comparison of The Effects of Vitrification on Gene Expression of Mature Mouse Oocytes Using Cryotop and Open Pulled Straw
Objective Oocyte cryopreservation is an essential part of assisted reproductive technology (ART) which was recently introduced into clinical practice. This study aimed to evaluate the effects of two vitrification systems (Cryotop and Open Pulled Straw, OPS) on mature oocytes gene expressions. MaterialsAndMethods The survival rate of metaphase II (MII) mouse oocytes were assessed after cryoprese...
متن کاملOpen Pulled Straw (OPS) Vitrification of Mus Musculus Morula and Blastocyst Survival in Two Common Cryopreservation Medias
The objectives of this study were to: (1) determine an optimal cryoprotectant of mice embryos; and (2) determine whether morula or blastocyst stage is ideal for vitrification in both medias. One experiment was performed using two different medias for vitrification with open pulled straws (OPS) with morulae and blastocysts. In the first protocol, we called V, embryos were exposed to 10% ethylene...
متن کاملOpen-pulled straw vitrification differentiates cryotolerance of in vitro cultured rabbit embryos at the eight-cell stage.
The objective was to determine cryotolerance of in vitro cultured rabbit embryos to the open-pulled straw (OPS) method. Overall, 844 rabbit embryos at pronuclear, 2- to 4-cell, 8-cell, and morula/blastocyst stages were vitrified, and ≥ 1 mo later, were sequentially warmed, rehydrated, and subjected to continuous culture (n = 691) or embryo transfer (ET, n = 153). Embryos vitrified at the 8-cell...
متن کاملEffect of vitrification on number of inner cell mass in mouse blastocysts in conventional straw, closed pulled straw, open pulled straw and cryoloop carriers.
OBJECTIVE To compare the effect of using open and closed carriers on count of inner cell mass in vitrified mouse blastocyst after warming. METHODS The experimental study was conducted at Ahvaz Jundishapur University of Medical Sciences, Ahvaz, Iran, from April to September 2010. Forty female NMRI (Naval Medical Research Institute, USA) mice were injected with pregnant mare's serum gonadotropi...
متن کاملNo Peri- and Postnatal Effects on Calves Born After Transfer of in Vitro Produced Embryos Vitrified by the Open Pulled Straw (OPS) Method
The general objective of this study was to perform follow-up studies including selected peri- and postnatal characteristics on calves born after transfer of in vitro produced (IVP) embryos vitrified by the 'Open Pulled Straw' (OPS) method. An overall pregnancy rate of 16% after transfer of the OPS-vitrified IVP embryos was achieved and resulted in birth of 9 calves, with 11 AI calves serving as...
