Discovery of the day
This Review demonstrates that mammary gland stem cells, characterized by self-renewal and multipotency, are dynamically regulated by intrinsic factors such as TP53 and signaling pathways including Wnt, which are often co-opted during tumorigenesis. Recent advances in single-cell transcriptomics and lineage tracing reveal unexpected diversity and plasticity within these cell populations, with physiological changes like pregnancy and aging modifying the microenvironment to create windows of increased cancer susceptibility. For clinical practice, these insights provide a framework for understanding breast cancer heterogeneity, highlighting potential therapeutic targets and informing evidence-based decisions about risk stratification and treatment selection for improved patient outcomes.
