(A) Phase contrast photomicrograph of unfixed endometrial stromal cells in vitro forming multilayered structures with a central cavity. (B–D) Photomicrographs of paraffin-fixed sections of endometrial outgrowths in three-dimensional fibrin matrix showing typical histological architecture of endometrial cells, (B) typical endometrial glands staining with anticytokeratin, (C) glands and stroma viewed under phase-contrast, and (D) normal nuclear morphology with the DAPI fluorescent stain. Bar = 25 μm.
