DU 145 was isolated by K.R. Stone et al from a lesion in the brain of a patient with metastatic carcinoma of the prostate and a 3 year history of lymphocytic leukemia. The line is not detectably hormone sensitive, is only weakly positive for acid phosphatease and isolated cells from colonies in soft agar. Ultrastructural analyses of both the cell line and original tumor revealed microvilli, tonofilaments and desmosomes. Many mitochondria, well developed Golgi and heterogenous lysosomes. The cells do not express prostate antigen.
