Abstract: Mammary stem cells The existence of mammary stem cells has been inferred from genetic analysis of human breast tissue, and from the fact that mouse mammary gland can regenerate from tissue fragments. Two groups now report the isolation of mammary stem cells from mice. Shackleton et al. use a technique based on the introduction of a marker for stem-cell function. A single cell from this population then showed its potency by regenerating an entire mammary gland in vivo. This population of cells is expanded in a pre-malignant mammary tumour model, providing support for the concept of a mammary cancer stem cell. In a paper published online, Stingl et al. report the use of a powerful limiting dilution transplant procedure to purify to near homogeneity a rare subset of adult mouse mammary cells that can individually regenerate an entire mammary gland within six weeks.
