BM cells (1 × 105/mL) from 5-FU–treated hG-CSFR Tg mice or littermates were incubated with hG-CSF (20 ng/mL) or mIL-3 (10 ng/mL). On day 7 of incubation, blast colonies were individually lifted from the culture and replated to a secondary culture containing mSCF (100 ng/mL), mIL-3 (10 ng/mL), EPO (2 U/mL), TPO (20 ng/mL), and IL-6 (100 ng/mL). Data represent the number of colonies on day 8 of the secondary culture.
