    摘要: A method for isolating cells which have a suprabasal position and expresses epithelial specific antigen but no sialomucin is provided. The isolated cells are shown to share many of the properties expected of a mammary gland stem cell. Three permanent cell lines that are capable of proliferating and capable of differentiating into cells of mammary gland luminal epithelial and myoepithelial cell lineages were established. Such cells form elaborate branching structures resembling uncultured terminal duct lobular units both by morphology and marker expression both in vitro and in vivo. Evidence is provided that these keratin K19 expressing cells most probably is the cells in which breast cancer arises. Thus they constitute a model not only for the developing breast, but also for the development of breast cancer. Also disclosed are the uses of such isolated cells or the cell lines as a model system of the mammary gland for pharmacological studies and their uses in tissue repair or transplantation.

    摘要: The present invention describes a novel gene, EPSTI1 for epithelial stromal interaction 1 (breast), which is upregulated upon direct interaction between tumour cells and stromal cells in the tumour environment of the breast. The full-length EPSTI1 cDNA was isolated and characterized with respect to nucleotide sequence, chromosomal organization and localization, i.e. the nucleotide sequence encoding the EPSTI1 polypeptide, the EPSTI1 polypeptide itself is disclosed herein. Furthermore, the present invention discloses the use of said gene for production of pure EPSTI1-protein. Finally the use of the EPSTI1 gene as a tool or diagnosis and prognosis of cancer, especially as a specific toll to detect metastatic cancer and invasive cancer is disclosed.
