摘要
Sertoli cells in the immediate vicinity of testicular tumors (seminoma and teratoma) display a conspicuously high number of nuclear bodies. These organelles show a great structural variability and may reach an unusually large size. Apart from the well-known types, there are variants with a granular, a fibrillar and an amorphous component which thus resemble complete nucleoli. This finding, as well as the close contact between nuclear bodies and nucleoli and the inverse relationship in the size of both organelles, supports the concept that nuclear bodies may originate from nucleoli. © 1979 Academic Press, Inc.
