Comparison of cell morphological changes in mPB- and CB-derived CD34+ cell cultures. CD34+ cells selected from mPB and CB were cultured for 21 days in vitro. Morphological changes in differentiated cells from both sources were similar. No remarkably different patterns were found in the Giemsa staining photos (a). Based on the erythrocyte cell type counting at the end of each phase, the mPB-derived cells matured more rapidly than the cells derived from CB, even though cells from both sources have similar maturation patterns (b).
