Fig. 9From: Limb patterning genes and heterochronic development of the emu wing budExpression of Gremlin, Twist1, Msx-2 and Mkp-3 in emu and chicken limb buds. a Whole-mount in situ hybridization shows localization in limb buds. b RNA-seq shows relative expression levels in emu versus chicken at stages 20–21. Adjusted p < 0.05 denoted by asterisks). Both Gemlin-1 and Msx-2 showed elevated expression in emu forelimb buds relative to hindlimb buds at stages 20–21Back to article page
