SDF-1α (human) serves as a chemotactic agent for mononuclear cells through its interaction with the CXCR4 receptor, facilitating critical biological processes such as stem cell homing, retention, survival, and proliferation, in addition to cardiomyocyte repair, angiogenesis, and ventricular remodeling post-myocardial infarction. It holds significant utility in cardiovascular disease research [1] [2].
