[Ascitic form the human cancer transplantable to thymus-deprived mice].

An ascitic form of tumor was obtained in thymus-free BALB/c mice from a solid strain of human mammary carcinoma. It passed 32 serial transplantations. The paper describes the kinetics of the tumor growth. Cytological and biochemical examinations of the ascitic form of mammary carcinoma demonstrated its appurtenance to human malignant tumors of the mammary gland.
