Figure 7.

The Location of TLR4 protein was Similar in the Magnum, Isthmus, Uterus, and Vagina. Cross‐sections of the magnum, isthmus, uterus, and vagina are depicted in the pictures (A, E, I, and M) at low magnification: B, F, J, and n refer to the amplification for the epithelium in the magnum, isthmus, uterus, and vagina, respectively; the secretory glands in the magnum, isthmus, uterus, and vagina are described C, G, K, and O, respectively; and D, H, I, and p show the negative controls for the magnum, isthmus, uterus, and vagina, respectively. All sections were counterstained with hematoxylin. No immunoreaction products were observed. Positive staining was observed on the ciliated cell superior surface and cilium surface (white thin arrow head), secretory cell superior surface (white thin arrow), secretory cell lateral membrane (white fat arrow head), secretory cell basal membrane (white fat arrow), secretory gland vesicles membrane (black thin arrow), longitudinal muscle (black fat arrow), circular muscle (black fat arrow head), and blood vessel endothelium (black thin arrow head). Scale bars: 50 μm (A, D, E, H, I, L, M, and P), 20 μm (B, F, J, and N), and 10 μm (C, G, K, and O).
