Characteristics of human EPCs. MNCs were cultured for 7 days, and adherent cells lectin binding (green, exciting wavelength 477 nm) and DiLDL uptake (red, exciting wavelength 543 nm) were assessed under a laser scanning confocal microscope. Double positive cells appearing yellow in the overlay were identified as differentiating EPCs (×400). Group rapamycin 5.0 g/ml (B1, B2, B3) significantly decreased the number of EPCs compared with control group (A1, A2, A3).
