Abstract: | Summary Close contacts between endothelial and smooth muscle cells in teleost (Prochilodus scrofa) blood vessels are described for the first time in the present study. More frequently are seen finger-like, club-shaped or foot-like endothelial processes that come into close contact with the plasma membrane of a smooth muscle cell. Rarely, some myoendothelial contacts occur between the finger-like protrusions that arise from both the endothelial and from the smooth muscle cells. The functional significance of the myoendothelial connection is discussed. |
