  1. Note:Tha indicates SERCAs inhibitor Thapsigargin. NS-8593 is a TRPM7 specific inhibitor. Mib indicates T-type Ca2+ channels inhibitor Mibefradil. GSK-7975A is an Orai1 specific inhibitor. PA indicates survival embryos of all activated oocytes after activation. PN indicates pronuclear embryos from surviving oocytes. 2-Cell indicates cleaved embryos in pronuclear fertilized eggs. “X” indicates none available data. The significance of differences between Inhibitors and Ctrl group were analyzed by the Chi-square test and p < 0.05 (*) was considered statistically significant
