A Representative images of cleavage and blastocyst fromation. Scale bar = 50 μm. B The survival rate after thawing. C The rate of cleavage formation. D The rate of blastocyst formation. “n” represents the cell number used in this experiment. Data are presented as mean percentage (mean ± SEM) of at least three independent experiments. *P < 0.05, **P < 0.01, ns non significanceBack to article page
