Objective: To detect the different expression of the protein expression of SOCS1, SOCS2, SOCS3 in maternal - fetal interface of mice with normal pregnancy and recurrent spontaneous abortion (RSA) . Methods: CBA/J × BALB/C and CBA/J × DBA/2 were used as normal pregnancy and RSA model respeetively. The protein expressions of SOCS1, SOCS2 and SOCS3 in decidual and placental tissues on day 14. 5 of gestation were detected by Western blotting. Results : Compared with normal pregnancy model mice, the expression of SOCS1 was significantly incre...
