From: Single-cell analysis of menstrual endometrial tissues defines phenotypes associated with endometriosis

Fig. 1

ME contains endometrial tissues. Histological analysis of endometrial tissues isolated from the menstrual effluent (ME) from 4 separate subjects: A control subject, B, C two subjects with pathologically confirmed endometriosis, and D subject with chronic symptoms of endometriosis (not yet diagnosed). Upper panels for A–D: H&E staining is shown in two panels at two magnifications for each individual: A 40X (left) and 200X (right), B 100X and 200X, C 100X and 200X, and D 40X and 200X; arrowheads point to glandular epithelium. Sections show typical late secretory/menstrual endometrium with expanded stroma containing scattered inflammatory cells and secretory and inactive type glands. Lower panels for A–D: immunostaining with anti-CD10 and anti-CD56 antibodies to detect stromal cells (left) and uterine NK (uNK) cells (right), respectively, at 100X. Scale bars are shown in each image
