Localization of FcRn in RMFR of young abomasum ALNA. From left to right column, the paraffin sections were stained with hematoxylin and eosin (H&E), immunohistochemistry for FcRn, hematoxylin counterstain (as negative control), respectively. a non-FAE represents non-follicle-associated epithelium in the top panel, and FcRn positive expression was mainly distributed in membrane of the epithelial cells (arrow); b FAE represents follicle-associated epithelium in the second panel from top to bottom and FcRn positive expression was mainly distributed in membrane of the epithelial cells (arrow), but the expression level was lower than that in non-FAE; c Vessel, FcRn was highly expressed both in vascular endothelial cells and smooth muscle cells (arrow); d Smooth muscle, FcRn was also highly expressed in basement membrane of smooth muscle (arrow).
