Detection of Cannabinoid Receptor Expression by Endometriotic Lesions in Women with Endometriosis as an Alternative to Opioid-Based Pain Medication

Figure 2

Expression of CD10 by the endometrial stromal cells in normal ovaries and ovary with endometriosis. (a) Section of a normal ovary. No CD10-positive stromal cells are seen. (b) Section of an endometrium showing stromal cells expressing CD10. However, epithelial cells in the endometrial glands were negative for CD10 expression. (c) Section of an ovary with endometriosis showing intense expression for CD10 by many stromal cells. Similar to normal endometrium, epithelial cells in endometriotic lesions (EL) did not show CD10 expression. E = epithelium; EG = endometrial glands; EL = endometriotic lesion; S = stroma; 40x = magnification. Arrows indicate examples of immunopositive CD10 cells.
