The expression of subunits α5,β1,β3 was detected in normal morulas and increased in blastocysts. The expression of subunit α1 was not detected in morulas or blastocysts, but detected only in outgrowing trophocytes. 3. Expression of integrin β3 in irradiated group embryos was weaker than that of normal group. There was no expression of integrin α1 both in morulas and blastocysts in irradiated group and no difference in the expression of subunits α5 and β1 between these two groups.

结果：1、超声波照射组胚胎贴附率、滋养细胞外延生长率均显著低于正常胚胎。2、正常胚胎桑椹胚期即有α5、β1、β3整合素表达，而无α1表达；囊胚期α5、β1、β3表达增强，仍无α1表达；α1只出现在外延生长的滋养细胞。3、超声波照射组胚胎β3整合素的表达明显弱于正常组，且未见α1表达；而α5、β1的表达两组间无差异。
