Fig. 5From: Alterations of miR-16, miR-let-7a and their target genes expression in human blastocysts following vitrification and re-vitrificationTUNEL staining in human blastocyst. The nuclei are stained by hoechst (blue color). the apoptotic nuclei are stained by TUNEL (red color). A-C, Apoptosis in fresh human blastocysts. D-F, Apoptosis in vitrified/warmed human blastocysts.
