Extended Data Fig. 4: Single-cell expression of AER genes and genes at the Lbx1-Fgf8 locus.

a–c, Dot plots showing expression and percentage of expressing cells for Fgf8 and MusD-Dac1J at E11.5 (a), 6 AER genes (Dlx1, Dlx5, Dlx6, Msx2, Wnt6, and Fgf4) at E9.5, E10.5 and E11.5 (b), and the 5 genes at the Lbx1-Fgf8 locus at E9.5, E10.5 and E11.5 (c). Data are shown in the 7 forelimb cell cluster in wild-type (grey) and Dac1J/Dac1J (green).
