Fig. 5
Expression of 370 highly connected intra-module hub genes across the five tissue layers. All hub genes are derived from nine modules marked with asterisks in Additional file 6: Figure S3A with high MM values (MM ≥ 0.7). Each line represents the scaled log2 transition of average FPKM value for each individual gene. Among them, 29 genes being highlighted with yellow are reported previously and 187 genes that emphasized with blue font are involved in seven Fuzzy c-means clusters. Particularly, the Wnt related genes and their receptors (Frizzled genes) are emphasized with bold italic. ‘@’: MM value ranged from 0.7 to 1. ‘#’: genes related to angiogenesis. ‘$’: genes related to cartilage/bone development. ‘C’: Cluster ID related to Fuzzy c-mean Clustering Analysis
