The development of primordial follicles is a complex process regulated by various signaling pathways. Among these pathways, the bone morphogenetic protein 4 (Bmp4) signaling pathway plays a critical role in controlling follicular survival and growth. Bmp4 exerts its effects on follicular development by activating the Smad signaling pathway. However, the precise mechanism of Bmp4Smad signaling in primordial follicle development remains unclear.Objectives:This research aims to investigate the role and mechanism of the Bmp4Smad signaling pathway in mouse primordial follicle development. Specifically, this study aims to determine the effect of Bmp4 on primordial follicle survival, growth, and differentiation, as well as the downstream targets of the Smad pathway that mediate these effects.Methods:The study will use a mouse model to investigate the role of Bmp4Smad signaling in primordial follicle development. The ovaries of newborn mice will be collected and cultured in vitro in the presence or absence of Bmp4. The effects of Bmp4 on follicular survival, growth, and differentiation will be assessed by histological examination and immunofluorescence staining. The downstream targets of the Smad pathway will be identified by transcriptome analysis.Expected results:It is expected that Bmp4 will promote primordial follicle survival and growth, and induce the initiation of follicular differentiation. The transcriptome analysis is expected to identify novel targets of the Smad pathway that mediate these 精品文档---下载后可任意编辑effects and provide insights into the mechanistic basis of Bmp4Smad signaling in primordial follicle development.Conclusion:This study will contribute to our understanding of the mechanisms that regulate mammalian follicular development and may provide new targets for infertility treatment.
