(A) Gating strategy for cell cycle analysis of HSC/P populations in Dek mice after sublethal irradiation. (B–Q) Cell cycle analysis of the hematopoietic stem cell and progenitor compartments in untreated (n=4 each genotype) and irradiated (n=5 each genotype) Dek WT and KO mice (n=5). The percentage of cells in G0/quiescence (B,F,J,N), G1 phase (C,G,K,O), S phase (D,H,L,P) and G2M phase (E,I,M,Q) phase are shown and were determined after FACS analysis.
