Immunohistochemical localization of α4 and β3 integrin subunits in the endometrium from controls and from copper IUD T200 users. (A), A positive staining for mouse anti-human β3-subunit in the endometrial gland (arrow) on day 8 after ovulation in a control patient’s menstrual cycle. (B), A positive staining for α4 in a gland in an IUD user (arrow) and negative expression in the lumen as expected (arrow head). (C), The same sample stained for β3. Observe the negative expression in the gland (asterisk) and in the lumen (arrowhead). (D), A patient with negative β3 in glands (asterisk) and lumen (arrowhead), but with a positive-staining stromal epithelium (white arrow). (Original magnification, ×200.)
