Effect of MSPCs on the reconstitution of hematopoiesis. (A) Schematic shows the in vivo experimental procedure. (B) Number of BMMNCs per tibia 5 months after transplantation; *P < .001 for comparison of mice injected with WT MSPCs versus PBS or Fancg^−/− MSPCs. (C) CFU-Cs per tibia; *P < .001 for comparison of mice injected with WT MSPCs versus PBS or Fancg^−/− MSPCs. *P < .01 for comparing recipients injected with WT MSPCs versus PBS or Fancg^−/− MSPCs. Data represent mean (± SE) of CFU-GMs from 5 mice in each group.
