APOE and endometriosis: Next, we aimed to perform a gain of function experiment whereby exogenous Apoe (mimetic) was delivered into the peritoneal cavity of mice with experimentally induced endometriosis (intact mice); the Apoe mimetic (COG-133, 3 μM in 200 μL sterile H2O) or vehicle were delivered daily (via intraperitoneal injection), with injections initiated at the same time as ectopic tissue transfer and for 2 wk following.
