Notes. Whole-femur bone marrow from Fancd2+/+, Fancd2+/− and Fancd2−/− mice were irradiated in single cell suspension with doses between 0–8 Gy as described in the Methods section. CFU-GM, BFU-E and CFU-GEMM were scored when colonies reached ≥50 cells in days 10–13. Results are the mean ± SEM of three separate experiments.
P1 = comparison between +/+ group and −/− group.
P2 = comparison between heterozygote +/− group and −/− group.
