Fig. 3

Gene networks of the top enriched modules at each stage of duct formation. Networks were visualized using top 50 or 100 highly connected genes. Colour of nodes show their DEG status. Pink nodes are statically DEGs (compared to stage 4.5 posterior control) and red nodes are DEGs in both static and dynamic comparisons. For dynamic changes it has been compared with the previous stages except for E4.5-Ant. (compared to 4.5 posterior stage). Grey nodes are non-DEGs. Larger nodes have higher degree of “hubness”. Only 500 or 1000 highly weighted edges are shown. Thicker edges (darker colour) represent higher weight
