Fine structural relation between the Sertoli cell and the differentiating spermatid in the human testis

Summary

The structural relationship between the Sertoli cell and the developing spermatid was studied with the electron microscope. In the contact area of the Sertoli cell with the anterior part of the developing spermatid, a filamentous structure is observed. This structure consists of fine tubular filaments about 100 Å in diameter associated with dense material. The functional significance of the structure is discussed.
