abstract：:The mammary gland is composed of multiple types of epithelial cells, which are generated by mammary stem cells (MaSCs) residing at the top of the hierarchy. However, the existence of these multipotent MaSCs remains controversial and the nature of such cells is unknown. Here we demonstrate that protein C receptor (Proc...
