Simplistic model of mammary epithelial cell differentiation hierarchy. a Schematic outline of a ductal-alveolar unit with location of the various cell types indicated. b A putative map of mammary epithelial cell differentiation. A multipotent stem cell present during development gives rise to luminal epithelial and basal stem cells, which further divide into luminal and basal progenitors during puberty. Ductal and alveolar hormone-receptor negative progenitors are distinct lineages and there is also a separate hormone receptor positive luminal lineage
