Figure 4 (A) Time course of changes in circulating CD34+MNC count after left anterior descending coronary artery (LAD) ligation in different experimental groups. (B) Representative images of double-stained cultured cells (1,1'-dioctadecyl-3,3,3',3'-tetramethylindocarbocyanine-labeled acetylated low density lipoprotein [Dil-ac-LDL] and Ulex europaeus agglutinin I [UEA-I]) at baseline (a, b) and 1 week after LAD ligation (c, d) from dogs with and without erythropoietin (EPO) treatment immediately after LAD ligation. (C) Quantitative analysis of endothelial progenitor cell culture assay. *p < 0.05 vs. the control group. p < 0.05 vs. baseline.
