Extended Data Fig. 5: Emx2 is upregulated for a prolonged period and specifically expressed in the lateral skin mesenchyme.
From: Emx2 underlies the development and evolution of marsupial gliding membranes

a, Differential gene expression between patagium and shoulder skin (Data corrected for multiple comparisons; FDR < 0.1) from postnatal day 6 (P6) to P10 (left) and P11 to P15 (right). Yellow represents genes more highly expressed in the patagium; pink are genes more highly expressed in the shoulder; grey are genes without differential expression. b, Immunohistochemistry for EMX2 in sugar glider tissue prior to patagium outgrowth (P1) and as outgrowth begins (P5). Scale bars in b: 500 μm (zoomed out) and 100 μm (zoomed in).
