Delay in the appearance of CD61 and CD41a expression in MKs generated from CB with respect to PB.

Comparative analysis of the megakaryocytic markers CD61, CD41a, and CD42b during MK differentiation of the CD34⁺ cells cultured in the presence of TPO (100 ng/mL). Cells were labeled with either PE- or FITC-conjugated MoAbs and analyzed by flow cytometry. ●, CB; ○, PB. (Mean ± SEM values from 5 experiments.)
