Fig. 4.
Effect of Myelopoietin (MPO) administration on the bone marrow-derived concentration of GM-CFC, MK-CFC, and E-BFU in 600 cGy total body x-irradiated (250 kVp) animals.
Clonogenic activity was observed before (baseline [BL]) and on days 7, 14, 21, and 46 after TBI and administration of MPO (n = 5) or a control protein (n = 11, HSA or AS) as described in Methods. Clonogenic concentrations (per 105 MNC) are reported as mean values ± SEM. Asterisk (*) denotes significantly different from BL (P < .05); H denotes significantly greater than control protein, time-matched controls (P < .05); ↓ denotes zero values; ND denotes not done.
