CXCR2 loss in germline Cxcr2 knockout mice delays postnatal mammary ductal outgrowth and reshapes stromal architecture, with decreased adipocyte size and increased collagen deposition.
- Why it matters: CXCR2 is linked to inflammatory remodeling in disease, but its function in mammary morphogenesis and epithelial–stromal coordination is unclear.
- What they did: The study analyzed postnatal mammary gland development in germline Cxcr2 knockout mice, assessing ductal outgrowth, epithelial area, stromal structure, and immune cell composition.
- The result: Defects in ductal growth and stromal remodeling occurred alongside severe systemic immune dysregulation, suggesting CXCR2 indirectly regulates development by coordinating immune and stromal microenvironment rather than epithelial cell-intrinsic effects.
