Figure Lengend Snippet: DNA-Damage Responses Are Induced, and the Strand Breaks Are Accumulated in FA FL HSPCs (A) Representative γH2AX foci in SCA1 + FL cells (60× objective lens; the scale bar represents 5 μm). (B) Quantification of γH2AX foci per cell (n = 3 WT and 3 KO from three litters). (C) Representative RAD51 foci in SCA1 + FL (60× objective lens; the scale bar represents 5 μm). (D) Quantification of cells positive for foci (p = 0.02, n = 6 WT and 6 KO from three litters). (E) Expression of DDR genes in SCA1 + FL cells (p = 0.08, 0.44, 0.06, 0.22, and 0.005, respectively; n = 4 WT and 4 KO from three litters). (F) Expression of selected DDR genes in ASL-sorted FL cells (p = 0.08, 0.5, 0.04 respectively; n = 3 WT and 3 KO from two litters). (G) Olive tail moment of 428 SCA1 + FL cells from seven WT animals and 288 SCA1 + FL cells from five Fancc − / − animals from four litters (p = 0.003). (H) Olive tail moment of 289 SCA1 + FL cells from five WT animals and 267 SCA1 + FL cells from five Fancd2 − / − animals from four litters (p = 0.04). (I) Representative alkaline comets of SCA1 + FL cells (20× objective lens; the scale bar represents 20 μm). Error bars reflect SEM, and asterisks indicate ∗ p ≤ 0.05 and ∗∗ p ≤ 0.01.
