[ effect of re-vitrification on developmental rate and Bax, Bcl-2, and ErbB4 gene expressions in mouse embryos]

ABSTRACT

Objective: Vitrification is a convenient, effective method for freezing and storing embryos. Under certain situations, such as an unsuitable endometrial environment, extra embryos can be re-vitrified for future use. There is inadequate data on the effects of revitrification on embryos, so we have evaluated the effects of re-vitrification on the development rate and expression of apoptotic and implantation genes
