No correlation between endothelial progenitor cell numbers and intima size. (A) The number of endothelial progenitor cells (EPCs; Ter119−/CD45lo/c-Kit+/Sca1+) in peripheral blood was determined at the end of the study. Data of individual mice and means of different treatment groups are indicated. (B) Regression analysis was performed on endothelial progenitor cell numbers and intimal area.
