MSH: A specialized barrier, in the TESTIS, between the interstitial BLOOD compartment and the adluminal compartment of the SEMINIFEROUS TUBULES. The barrier is formed by layers of cells from the VASCULAR ENDOTHELIUM of the capillary BLOOD VESSELS, to the SEMINIFEROUS EPITHELIUM of the seminiferous tubules. TIGHT JUNCTIONS form between adjacent SERTOLI CELLS, as well as between the ENDOTHELIAL CELLS.,CSP: specialized barrier in the testis between the interstitial blood compartment and the adluminal compartment of the seminiferous tubules; formed by layers of cells from the vascular endothelium of the capillaries to the seminiferous epithelium; tight junctions form between adjacent sertoli cells as well as between the endothelial cells.
