Methods are disclosed for isolating and culturing human mammary epithelial cells of both normal and malignant origin. Tissue samples are digested with a mixture including the enzymes collagenase and hyaluronidase to produce clumps of cells substantially free from stroma and other undesired cellular material. Growing the clumps of cells in mass culture in an enriched medium containing particular growth factors allows for active cell proliferation and subculture. Clonal culture having plating efficiencies of up to 40% or greater may be obtained using individual cells derived from the mass culture by plating the cells on appropriate substrates in the enriched media. The clonal growth of cells so obtained is suitable for a quantitative assessment of the cytotoxicity of particular treatment. An exemplary assay for assessing the cytotoxicity of the drug adriamycin is presented.
