Fig. 4.
Frequency distributions of megakaryocytic colony sizes in cultures of healthy, ET and PV (experiment 160) and healthy and 2°T (experiment 198) progenitor cells.
Abscissa: cell number per colony; ordinate: number of megakaryocytic colonies (per 1.5 × 105 PBMNCs per 0.7 mL) with a given number of cells per colony.
