Total zona pellucida removal of vitrified–warmed blastocysts. (A) Expanded blastocyst after warming procedure. (B) Blastocyst shrinkage by high osmolality solution and pipetting. (C) Partial removal of zona pellucida from blastocyst by laser. (D and E) Complete zona pellucida removal by gentle pipetting. (F) Blastocyst with zona pellucida completely removed. Arrowhead indicates the blastocyst. Scale bars represent 100 µm.

3. Figure 2
Blastocyst adhesion and outgrowth after assisted hatching. (A) Cumulative blastocyst adhesion rate at 0, 12, 18, 24, 36, 48, 72, 96 h after assisted hatching treatment. (B) Time required for adhesion. (C) Outgrowth speed of blastocysts. Error bars represent the standard error of the mean. Bars labelled with asterisk are statistically significantly different from each other (P < 0.05). Due to a low number of hatched and adhered blastocysts (n = 3) in the intact group, adhesion time and blastocyst outgrowth speed in the Intact group were not statistically compared with those of the P- or C-removal groups.

4. Figure 3
Integrin mRNA expression in blastocysts after assisted hatching. (A) ITGA5 mRNA expression in blastocyst after assisted hatching treatment. (B) ITGB1 mRNA expression in blastocyst after assisted hatching treatment. Error bars represent the standard error of the mean. Bars labelled with distinct letters are statistically significantly different from each other (P < 0.05).
