Abstract
Objective - Endothelial progenitor cells (EPCs) that may repair vascular injury are reduced in patients with coronary artery disease (CAD). We reasoned that EPC number and function may be increased by granulocyte colony-stimulating factor (G-CSF) used to mobilize hematopoietic progenitor cells in healthy donors. Methods and Results - Sixteen CAD patients had reduced CD34 +/CD133 + (0.0224±0.0063% versus 0.121±0.038% mononuclear cells [MNCs], P+/VEGFR-2 + cells, consistent with EPC phenotype (0.00033±0.00015% versus 0.0017±0.0006% MNCs, P+/CD133 + cells from 0.5±0.2/μL to 59.5±10.6/μL and CD133 +/ VEGFR-2 + cells from 0.007±0.004/μL to 1.9±0.6/μL (both P+ cells that coexpressed the homing receptor CXCR4 (30.4±8.3/μL, P
