Endothelial FSHR expression at the periphery of invasive breast cancer. This picture illustrates that tumor FSHR+ blood microvessels are arranged in a hierarchical pattern of arterioles - capillaries - venules. Immunohistochemical analysis was performed on paraffin-embedded sections of human breast cancer tissues with the use of FSHR323 antibody, followed by a secondary peroxidase-coupled antibody visualized with the use of the red-brown peroxidase-reaction product of AEC. Scale bar represents 50 μm.
