Composition of hematopoietic compartments in FL and blood in inbred mouse strains. (A) Percentages of LT-HSC and 5 progenitor populations in FLs across inbred mouse strains. (B) Percentages of primitive RBCs, definitive RBCs, and platelets across inbred mouse strains. E14.5 embryos from C57BL/6J (n = 24), C57BL/10SnJ (n = 16), C57L/J (n = 14), BALB/b (n = 16), C3H/HeH (n = 24), CBA/CaJ (n = 17), FVB/NJ (n = 21), and 129/SvEv (n = 31) strains were analyzed in 3 separate experiments, with data from 1 representative experiment shown.
