Fig. 6From: Limb patterning genes and heterochronic development of the emu wing budRNA-seq analysis of genes associated with limb bud outgrowth in emu versus chicken embryos (HH stages 20–21). Statistically significant differential expression (adjusted p < 0.05) is shown by asterisks. Black forelimb; white hindlimb. Fgf10 expression was higher in the emu forelimb bud than in the hindlimb bud at the time of outgrowth (stages 20–21)Back to article page
