Number of proplatelet-forming MKs at different days of culture, generated from CB and PB CD34⁺ cells grown in serum-free medium and in the presence of thrombopoietin (100 ng/mL). Data are referred to 10³ total MKs counted for each day of culture. Mean ± SEM from 3 separate experiments is presented.

P < .05 (Student t test).
