Isolation of myeloid-derived suppressor cells (MDSC) from endometriotic mice model and their immunomodulatory functions.

Abstract

Endometriosis is a chronic, painful disease whose etiology remains unknown. The development of novel therapies and diagnostic tools for endometriosis has been limited due in part to challenges in studying the disease. Recently, a few reports have shown that immunosuppressive cells, such as myeloid-derived suppressor cell (MDSC), may promote the progression of endometriosis. MDSCs are a heterogeneous group of myeloid cells with potent immunosuppressive and angiogenic properties. Here, in this chapter, we provide a detailed protocol to phenotype MDSC as well as to isolate and assess the functionality from the peritoneal cavity of a mouse model of surgically induced endometriosis. Importantly, the current mouse model has been widely used to study how the immune system, hormones, and environmental factors affect endometriosis as well as the effects of endometriosis on fertility and pain.
