IGFBP-4 is an inhibitor of canonical Wnt signalling required for cardiogenesis.
In the beta-actin panel of Fig.1C, a left band (OP-9) is similar to a right band (OP-9 + anti-BP4).
In the beta-Actin panel of Fig.3B, lane 1 and lane 2 bands from the left are similar.
In the "GATA-4" panel of Fig.3e, lane 1 and lane 6 bands from the left are similar to each other"
In Fig.3e, Lane 1 and 2 image from the left of a GATA-4 panel are a vertically flipped and resized version of lane 1 and 2 image from the left of Nkx2.5 panel.
In Supplementary Figure S3f, the left band of beta-actin panel is a resized version of that of Nkx2.5 panel.
