Abstract: | The testes of the crayfish, Procambarus paeninsulanus, were prepared for light and transmission electron microscopy. During early stages of spermatogenesis, when the spermatogonia are dividing, processes from a single Sertoli cell extend between numerous spermatogonia. As the cells enter meiosis, many points of contact can be observed between the Sertoli cell processes and spermatocytes. These desmosome-gap junctions are maintained between the germ and Sertoli cells until the early spermatid stage. |
