OBJECTIVE: To assess the effects of Bushenantai (BSAT) granule() on angiogenesis-related factors [E2, P, and vascular endothelial growth factor (VEGF)] at the maternal-fetal interface of recurrent spontaneous abortion (RSA) mice, and to evaluate the role of BSAT in promoting angiogenesis at the maternal-fetal interface by influencing the expression of sex hormones, and VEGF.
METHODS: A mouse model with normal pregnancy and another with Clark's classic RSA were established. The RSA mice were randomly assigned to six groups: normal, model, progesterone, high-doseBSAT granule (BSAT-H), medium-dose-BSAT granule (BSAT-M), and low-dose-BSAT granule (BSAT-L) (n = 10 for each group). The embryo loss rate and the histopathological changes in the decidual tissues were measured. Serum levels of estrogen (E2), progesterone (P), and VEGF were detected by enzyme-linked immunosorbent assay. The mRNA and protein expressions of estradiol receptor (ER), progesterone receptor (PR), VEGF, and vascular endothelial growth factor receptor 2 (VEGFR2) in the decidual tissues were identified by immunohistochemistry, Western blotting, and quantitative reverse transcription polymerase chain reaction.
RESULTS: The embryo loss rate in all groups that received BSAT treatment was reduced, while the number of blood vessels at decidual tissues was increased. The serum levels of E2, P and VEGF were elevated, and the mRNA and protein expressions of ER, PR, VEGF, and VEGFR2 in the decidual tissues were enhanced.
CONCLUSION: BSAT can improve angiogenesis at the maternal-fetal interface and reduce the embryo loss rate, which may be associated with its ability to increase the serum levels of estrogen, progesterone, and VEGF, in addition to up-regulation of mRNA and protein expression of ER, PR, VEGF, and VEGFR2 in the decidual tissue.
