Supplementary Figure 4: RA signaling does not affect the efficiency of SANLPC development.

(a) Individual data point dot plots of the flow cytometric analyses presented as stacked bar graph in Fig. 2e showing the proportion of NKX2-5+cTNT+ and NKX2-5-cTNT+ cells at day 20 of differentiation generated from mesoderm (3 ng/ml BMP4, 2 ng/ml ACTA) treated with retinoic acid (RA) on days 2-12 (n = 4). (b) Individual data point dot plots of the flow cytometric analyses presented as stacked bar graph in Fig. 2g showing the proportion of NKX2-5+cTNT+ and NKX2-5-cTNT+ cells at day 20 of differentiation generated from mesoderm (3 ng/ml BMP4, 2 ng/ml ACTA) treated with BMP4 (2.5 ng/ml) together with SB (5.4 μM) and/or different concentrations of retinoic acid (RA) between days 3-5. t-test: **P < 0.01 vs Nkx2-5-cTNT+ cells in untreated control condition (n = 4). All error bars represent s.e.m. d, day
