Abstract
Objective To find out the relationship between fetal growth restriction (FGR) and transforming growth factor -β1 (TGF-β1). Methods The levels of TGF-β1 in maternal serum and placental tissue of FGR were detected with using ELISA and immunohistochemistry technique, and it was compared with those of normal term pregnancy. Results The levels of TGF-β1 in maternal serum of FGR group were significantly higher than those of normal term pregnancy (76. 5 ± 33. 4 VS 47.6 ± 24. 2, t' = 4. 65, P ＜0. 05). As for the intensity of the immunohistochemistry signal, TGF-β1 in syncytiotrophoblastic cells of FGR was markedly higher than that of control group (81.82% vs 5.83%, P ＜0. 01). Conclusions The levels of TGF-β1 are closely related with FGR. Key words: Transforming growth factor beta1/ME ; Placenta/ME; Fetal growth retardation/DI
