Ultrastructural studies on the blood-testes barrier of the rat.
Typical pinocytic vesicles were visible in electron micrographs in both outer and inner cellular layers of rat boundary tissue. FF technique revealed that they formed characteristic ribbons of foveoli. Foveoles less numerous were present in outer lamina for the most part of the investigated material. So we believe that this phenomenon speaks in favor of myoblastic origin of that layer.
