Abstract

Androgen-independent, human prostate carcinoma cells (DU145) develop into solid, carcinomatous xenotransplants on the diaphragm of nu/nu mice. Tumors encompass at least two poorly differentiated cell types: a rapidly dividing, eosinophilic cell comprises the main cell population and a few, but large basophilic cells able to invade the peritoneal stroma, the muscular tissue, lymph vessels. Poor cell contacts, intracytoplasmic lumina, and signet cells are noted. Lysosomal activities are reflected by entoses and programmed cell deaths forming cribriform carcinomas. In large tumors, degraded cells may align with others to facilitate formation of blood supply routes. Malignant cells would spread via ascites and through lymphatics.
