Spontaneous Endometritotic Lesions Compared to Eutopic Endometrium in the Baboon

The development and progression of endometriotic lesions are poorly understood, but immune cell dysfunction and inflammation are closely associated with the pathophysiology of endometriosis. A lack of suitable 3D in vitro models permitting the study of interactions between cell types and the microenvironment is a contributing factor. To address this limitation, we developed endometriotic organoids (EO) to explore the role of epithelial-stromal interactions and model peritoneal cell invasion associated with lesion development (GSE202661). These organoids were compared to spontaneous endometriotic lesions from baboons (Papio anubis). Overall design: Endometriotic lesion tissues (n=4) were compared to eutopic endometrium (n=3).
