Embryonic mammary gland stem cells identified

Scientists have identified the mechanisms that regulate mammary gland development. Using a combination of lineage tracing, molecular profiling, single cell sequencing and functional experiments, they have demonstrated that mammary gland initially develops from multipotent progenitors during the early steps of embryonic mammary gland morphogenesis whereas postnatal mammary gland development is mediated by lineage-restricted stem cells.
