Immunohistochemistry of regions of the female reproductive tract with anti-CD9 and anti-α6 antibodies. Sections of the reproductive tract from mature female mice were stained with JF9. (A) A low-magnification cross-section of the utero–tubal junction (J) flanked by uterine epithelium (U) and oviduct (O) and higher-magnification sections of the uterus (B), the isthmus (C), and the oviduct (D) are shown. (C Inset) A section of C indicated by a red arrow is magnified four times. Sections of the isthmus were stained with an anti-α6A cytoplasmic tail antibody in the absence (E) or presence (F) of the immunizing peptide. Arrows in C–F indicate locations of positive apical staining.
