Abstract: The present invention relates generally to a method for the generation of a substantially homogenous population of undifferentiated cells. More particularly, the present invention relates to a method for isolating a substantially homogenous population of stem cells, and in particular, mammary stem cells (MaSCs). The MaSCs of the present invention are isolated on the basis of differential levels of proteins present on their cell surface. The MaSCs of the present invention are particularly useful as targets for identifying agents which modulate MaSC survival, self-renewal, proliferation and/or differentiation in both normal and diseased tissue such as, but not limited to, tumor tissue, and, also as source of tissue for the regeneration, replacement and/or augmentation of tissue damaged and/or lost after disease or injury.

Abstract: The present invention relates generally to a method for detecting an aberrant cell, and more particularly an aberrant epithelial cell, in a subject or in a biological sample from said subject and agents useful for same. More particularly, the present invention relates to a method of deleting an aberrant mammary epithelial cell. The presence of the aberrant cell or group of aberrant cells provides an indication of a particular disease or condition or a propensity for development of a disease or condition.
