From: Expression of follicle-stimulating hormone receptor by the vascular endothelium in tumor metastases
FSHR-expression in metastases to liver of breast cancer (A) and colon cancer (B). Immunohistochemical analysis was performed as for the Figure 1. Arrows point to the blood vessels. bc, breast cancer; cc, colon cancer. Panels C and D show FSHR expression in the normal appearing tissue surrounding metastasis of colon cancer to liver. Endothelial cells of the arterioles and capillaries (arrowheads) derived from the hepatic artery (HA) express FSHR (C). The majority of the branches of the portal vein (PV) do not express FSHR. No staining is visible in the central vein (CV) and its associated sinusoids (*) (D). The scale bar represents 20 μm in all panels.
