Representative FACS plots showing different profiles of endothelial (CD31) and hematopoietic (CD45 and CD235a) lineage positive cells (shown as red dots in Panel a–c) and gating strategy based on different expression levels of CD49f in the Lin− mammary epithelial cells (Panel d). (e) A schematic diagram shows experimental flow for sorted cells. SFD refers to sphere formation and differentiation assay and CFC refers to colony formation on irradiated NIH3T3 cells.
