Effects of re-vitrification of mouse morula and early blastocyst stages on apoptotic gene expression and developmental potential

ABSTRACT

Objective: re-vitrification of embryos immediately after thawing or after a culture period could be used to preserve the extra embryos after embryo transfer. This study aims to clarify the effect of re-vitrification on Bax and Bcl-2 gene expressions of compact and early blastocyst stage embryos
