Kinetic analysis of myeloerythroid progenitor recovery after sublethal ionizing radiation. (A) CFUs generated from mpx:eGFP; gata1:DsRed DN cells after recovery from 25 Gy irradiation. (B) Ratio of CFUs generated to number of mpx:eGFP; gata1:DsRed DN cells isolated and cultured from the lymphoid (●) and precursor (■) light scatter fractions (as diagrammed in Figure 2A). The x-axis is days after 25 Gy irradiation; day 0 fish were not irradiated. Data points represent the average of 3 individual biologic replicates performed in triplicate, and error bars represent SD.
