Endometrial assembloid model reveals endometrial adenogenesis regulation by estradiol-driven WNT7B expression [bulk RNA-seq]
Ontology highlight
ABSTRACT: Little is known about the adenogenesis of human endometrial glands. This study explored endometrial adenogenesis using a novel three-dimensional endometrial assembloid model that integrates human endometrial organoids (EOs) and human endometrial stromal cells (HESCs). The model effectively recapitulated endometrial tubular gland formation, underscoring the critical role of stromal-epithelial interactions. Transcriptomic analyses identified WNT7B as a key intrinsic regulator for EO-derived tubular gland formation, which is extrinsically regulated by TGFβ1-VDR interaction between HESCs and EOs. Estradiol stimulated endometrial gland development via WNT7B downregulation in EOs. This finding was validated in an estradiol-stimulated mouse model and clinical samples from women undergoing in vitro fertilization (IVF) cycles. Uterine-specific WNT7B knockout in mice further confirmed its inhibitory role in endometrial gland development. This study offers insights into endometrial adenogenesis and potential therapeutic targets for related endometrial disorders.
