Figure Legend Snippet: Loss of Puma prevents compensatory proliferation of stem cells upon DNA damage. (A) To compare the rates of proliferation in different stem cell populations, the mice of the indicated genotpyes were exposed to IR, and, on days 3 and 7, were injected i.p. with a single dose of BrdU. Four hours later, mice were sacrificed, and the percentage of BrdU+ cells was assessed by flow cytometry in the individual stem cell subsets or total bone marrow. The relative increase in proliferation (BrdU+ cells) in relation to untreated controls was calculated by using the following equation: (IR-induced proliferation percent − spontaneous proliferation percent)/(100 − spontaneous proliferation percent). Bars represent fold induction of BrdU+ cycling cells as mean ± SEM of three to four animals per genotype and three independent experiments. (*) Significant differences in BrdU uptake were observed between wild-type and puma−/− or p53−/− MPP (P < 0.03) and LT-HSC (P < 0.01) subsets at days 3 or 7 post-IR. (B) Mice were fed BrdU in drinking water for 12 d, yielding between 70% and 90% of labeling efficiency in both genotypes alike. Then mice were exposed to 1.75 Gy IR at days 0 and 7. The percentage of BrdU+ stem cell subsets was assessed by flow cytometry. IR-induced loss of BrdU as an indirect measure of proliferation was calculated by subtracting the percentage of BrdU+ cells of mice pre-exposed to IR from the percentage of BrdU+ cells in control animals. Symbols represent mean ± SEM of three to four animals per genotype and time point. Spontaneous BrdU loss was not different between genotypes (P > 0.78). (*) BrdU loss was significantly different at all time points after IR in MPP (P < 0.014) and LSK (P < 0.026) cells at days 3 and 7, and in LT-HSCs (P < 0.014) at days 7 and 10. (C) Cell cycle analysis using Ki67 was performed in control mice or mice exposed to IR 7 d before. The percentage of cells in G0 is plotted. Bars represent mean ± SEM of three animals per genotype. (*) The percentage of stem/progenitor cells in G0 was significantly higher in puma+/−, puma−/−, and p53−/− when compared with wild-type mice (P < 0.04).
