摘要

The maintenance of early pregnancy is a complex and distinctive process, primarily characterized by critical reproductive events such as embryo implantation, trophoblasts differentiation, decidualization, and extravillous trophoblasts (EVTs) invasion etc. However, dysregulation of these essential reproductive processes can result in various pregnancy complications, including recurrent miscarriage, preeclampsia, and fetal growth restriction etc. Notably, these complications exhibit an interconnected regulatory network that suggests shared underlying pathophysiological mechanisms. Meanwhile, the role of the BMP signaling pathway in sustaining early pregnancy is increasingly being investigated and elucidated. In this review, we have clarified the specific molecular mechanisms which are fundamental to essential reproductive processes and summarize an overview of animal models associated with BMP signaling molecules. In addition, we present a novel perspective on several contentious viewpoints regarding the functional roles of BMP ligands. Therefore, we anticipated a comprehensive understanding of the precise ways in which the BMP signaling pathway affects reproductive events during early pregnancy could provide new perspectives and approaches for preventing and addressing early pregnancy complications.
