Stereomicroscopic observation of endometriosis-like lesions.

Endometrial implants as labeled with CFDA-SE and observed at sacrifice by fluorescence stereomicroscopy in MIF-KO mice inoculated with endometrial tissue from syngeneic MIF-KO mice (KO/KO) or WT mice inoculated with syngeneic WT murine endometrial tissue (WT/WT) (controls). Endometrial implants in KO/KO mice treated with rhMIF (0.008 mg/kg) or WT/WT mice treated with ISO-1 (4 mg/kg) are shown. Implants were observed by optic light or epi-fluorescence (GFP). Merged images are shown.
