A) GO analysis for differentially expressed genes of cartilage transcriptome in regenerated cartilage of PEG‐CHI and PEG‐CHI‐KGN groups at 12 weeks after surgery. B) Pathway analysis for differentially expressed genes from the rabbit regenerated cartilage transcriptome. C) The most significant clustered module of differentially expressed genes was identified from the PPI network utilizing MCODE in Cytoscape. The more size nodes shown, the more degree nodes obtained. Interactions were color coded according to the combined scores, with darker edges corresponding to higher scores. D) RT‐PCR validation for essential genes in the most significant cluster in RNA‐Seq; data were expressed as mean ±SD (n = 3, P < 0.05).
