FSHR expression in human nonpregnant reproductive tissues. Tissues were stained with antibody FSHR-323 IgG2a (brown) and counterstained with hematoxylin (blue). A) Proliferative endometrium (magnification ×100). Labeled are glandular epithelium (G), endometrial stroma (S), and endothelial cells of an endometrial blood vessel (V). B) Secretory endometrium (magnification ×100). Labeled are glandular epithelium (G), endometrial stroma (S), and endothelial cells of the endometrial blood vessels (V). C and D) Cervix (magnification ×100). Labeled are cervical glands (G), cervical muscle (M), endothelial cells of cervical blood vessels (V), and arterial smooth muscle (AM). Corresponding negative controls stained with nonimmune IgG2a at the same concentration are shown in Supplemental Figure S9.
