A: Representative IHC staining with epithelial marker EpCAM, specific for epithelial cells in ovarian endometrioma tissue. Formation of CFUs by ovarian endometriotic epithelial cells seeded at clonal density for 21 days in vitro. B: Plate showing variation of CFUs. C: Small cluster of endometriotic epithelial cells at day 4. D: Intercalated and honeycomb-shaped ovarian epithelial cells. E: Morphology of endometriotic epithelial cells at day 10. F–I: Small and large CFUs. Phase contrast photomicrograph of a typical epithelial small CFU (F) and large CFU (G). Limiting dilution assay with small (H) and large (I) CFUs. Hematoxylin stain (H and I). Scale bars = 200 μm.
