Supplementary Figure 7: Expression analysis of genes involved in syndactyly/interdigital cell death.

In situ hybridization analysis were performed in E14.5 forelimbs from Dup(syn)/+ mutants and corresponding wt controls. Note increased expression for Bmp4 and Nog as well as expansion of Bmp4 expression in the interdigital space (arrows). Bars represent 200μm.
