Kinetics of primitive- and adult-type Mk colony formation.
Comparison in the kinetics of Mk colony formation between 7.5-dpc YS (○) and adult BM cells (■). Cells (1 × 105) from 7.5-dpc YS or adult BM were cultured in the presence of SCF, IL-3, IL-6, G-CSF, EPO, and TPO. The number of Mk colonies were counted every day for 2 weeks. The values shown are the mean ± SD in triplicate cultures.
