Expression of bone morphogenetic protein receptor (BMPR) during perinatal ovary development and primordial follicle formation in the hamster: possible regulation by FSH.

ABSTRACT: To understand whether bone morphogenetic protein plays any role in the formation of primordial follicles in the hamster, we examined the temporal and spatial expression of bone morphogenetic protein receptor (BMPR) mRNA and protein in embryonic (E) 13 through postnatal day (P) 15 ovarian cells and a possible regulation by FSH during the formation of primordial follicles on P8. BMPRIA and BMPRII mRNA levels were significantly higher than that of BMPR1B throughout ovary development. BMPRIA and BMPRII mRNA levels increased significantly on E14 and declined by P5 through P6. Whereas BMPRII mRNA increased again by P7, BMPRIA mRNA levels increased through P8 concurrent with primordial follicle formation. In contrast, BMPRIB mRNA levels increased greater than 10-fold on P7-9, with a further 3-fol
