Supplementary Figure 5: Comprehensive characterization of expression of Fgf signalling components within the early mouse embryo.

Box plots showing the mRNA expression level of Fgf ligands and downstream cytoplasmic signal effectors, collected for each stage from single-cell microarray analysis (66 WT cells including 36 cells from 6 embryos for E3.25, 11 and 11 cells from 3 embryos for E3.5 EPI and PrE, and 4 and 4 cells from one embryo for E4.5 EPI and PrE cells, respectively; and 35 Fgf4−/− cells including 17 cells from 3 embryos for E3.25, 8 cells from one embryo for E3.5 and 10 cells from one embryo for E4.5).
