Fig. 5. Comparison of the CFC content of Mpl^-/- and C57Bl6 mouse embryos at E11.5, E12.5 and E14.5. Total CFCs and CFU-GM, BFU-E, CFU-GEMM and CFU with MK content of (A) E11.5 AGM and (B) E11.5, E12.5 and E14.5 FL are presented. Half an AGM suspension and 5x10⁴ FL cells were used in each Petri dish. The results of a single experiment representative of two other independent experiments are shown. For each experiment, three independent Petri dishes were prepared and scored, and the results shown represent the mean±s.e. ^*, P<0.05.
