Myosin in early spermatids of the rat

Virchows Archiv B volume 38, pages 307–310 (1981)Cite this article

Summary

In order to obtain insight into the basic mechanism of cytoplasmic undulation in early spermatids, tubuli seminiferi of young adult rats were fixed in Stieve’s solution and examined immunohistochemically with anti-fast skeletal muscle myosin serum. A number of nuclei of spermatogonia, spermatocytes and spermatids stained intensely, but in addition the cytoplasm of early spermatids showed a positive reaction. It is suggested that myosin is involved in the cytoplasmic movements of earlier spermatids. The findings indicate a connection between contractile proteins and sterility in man.
