Abstract

A series of human germ cell-derived tumors were examined for the presence of nucleoli which persist through mitosis. Embryonal carcinomas, seminomas, and the cytotrophoblasts of choriocarcinomas had persistent nucleoli in more than 70% of mitoses. The differentiated cells derived from embryonal carcinomas, endodermal sinus tumors, and the more differentiated elements of choriocarcinomas only rarely had persistent nucleoli. These nucleoli appeared to remain transcriptionally active.
