Seminiferous tubule contractility is fundamental for sperm progression towards the rete testis; hence its regulation represents a key point in male fertility. Endothelin-1 (ET-1), a potent stimulator of smooth muscle contractility, has recently been shown to be produced in the testis, as well as to bind to specific receptors on myoid cells and thereby activate intracellular signaling. The present paper illustrates contraction of isolated myoid cells in response to ET-1 both in phase-contrast… CONTINUE READING
