Chronic non-healing wounds, prevalent in diabetic and vascular diseases, arise from dysregulated chemokine signaling that disrupts angiogenesis, immune coordination, and tissue remodeling. This review synthesizes current knowledge on chemokine biology in wound repair, with a focus on their spatiotemporal regulation across the hemostasis, inflammation, proliferation, and remodeling phases. We detail chemokine classification (CC, CXC, CX3C, and C families), receptor interactions, and downstream pathways, including G protein-dependent and β-arrestin-biased mechanisms. Furthermore, we evaluate emerging therapeutic strategies, including neutralizing antibodies, receptor antagonists, engineered chemokines, and biomaterial-based delivery systems designed to restore chemokine gradient integrity and promote healing. Recent advances in structural biology and protein engineering are highlighted as enabling the design of biased ligands and multi-target inhibitors to overcome chemokine redundancy. The review concludes that precision modulation of chemokine networks offers a promising translational framework to redirect chronic inflammation toward regenerative healing, thereby addressing a significant unmet clinical need in chronic wound management.
