Plating CD34-enriched BM-MNCs generated similar numbers of CE-EPCs as PB-MNCs, which contained significantly fewer progenitors. A: Cellular composition of MNCs obtained from PB or thawed BM before culture, as determined by flow cytometry. Data were obtained from four independent experiments. B: EPC yield by counting high-power fields from each source per million MNCs plated. C: Bright-field images of EPCs generated from MNCs obtained from thawed BM (with and without CD34 depletion) or PB after 7 days in culture. *Statistical significance at P < 0.05. Magnifications, ×200.
