摘要:: The cell line Rama 25 is derived from a mammary tumor induced in a rat by dimethylbenzanthracene. During rapid proliferation, Rama 25 cells appear as a single undifferentiated epithelial type; at high cell densities, however, small numbers of two other cell types are formed, which respectively resemble secretory and myoepithelial cells of the mammary gland, as judged by light and electron microscopy and immunofluorescent staining for casein (milk proteins). These additional cell types cannot be explained as contaminating cell populations since the cell line has been cloned several times; furthermore, the proportion of either can be increased by dimethylsulphoxide under different conditions. Specific epithelial features are seen by histological and ultrastructural examination of tumors formed by Rama 25 cells in immunodeficient mice. A line of the myoepithelial-like cells, Rama 29, isolated from a Rama 25 culture by cloning, is also described. We propose that the undifferentiated cell type is a form of mammary stem cell which can differentiate in culture.
