CD10 is a remarkable member of the major class of widely expressed cell surface proteins, endopeptidases. First identified in leukemia as a tumor-specific antigen (common acute lymphoblastic leukemia antigen), CD10 has become largely used in cancer diagnosis. However, its function in oncogenesis remains unclear. We previously identified CD10 as a tool to(More)
The major components of the mammary ductal tree are an inner layer of luminal cells, an outer layer of myoepithelial cells, and a basement membrane that separates the ducts from the underlying stroma. Cells in the outer layer express CD10, a zinc-dependent metalloprotease that regulates the growth of the ductal tree during mammary gland development. To(More)
Understanding the mechanisms of cancer initiation will help to prevent and manage the disease. At present, the role of the breast microenvironment in transformation remains unknown. As BMP2 and BMP4 are important regulators of stem cells and their niches in many tissues, we investigated their function in early phases of breast cancer. BMP2 production by(More)
Here we describe a protocol established in our laboratory to quantify early common progenitors/stem cells grown as spheres in non-adherent culture conditions. This protocol is based on the combination of two functional tests: the mammosphere assay to maintain and enrich early mammary progenitors/stem cells, and the epithelial colony-forming cells (E-CFC)(More)
Keller et al. (1) highlighted the use of the CD10 and epithelial cell adhesion molecule (EpCAM) markers to discriminate basal from luminal breast epithelial subpopulations. Based on the same two markers, we have previously developed a simple, robust, and reliable flow cytometry sorting technique to separate luminal populations cleanly from the rest of(More)
