Polymerization of sperm actin in the presence of cytochalasin‐B

Abstract
The polymerization of globular actin to fibrous actin which occurs when sperm are activated, was not inhibited by cytochalasin‐B. The acrosomal filaments and its component actin filaments formed in the presence of cytochalasin‐B; and once formed, the actin filaments did not depolymerize when exposed to cytochalasin‐B.
