Subtype-specific genes. Venn diagram representing numbers of fibroblastic- (green), chondroblastic- (red), and osteoblastic (blue)-specific differentially expressed genes obtained with factorial LIMMA analysis, considering chondroblastic versus osteoblastic (chondro vs osteo), fibroblastic versus osteoblastic (fibro vs osteo), and chondroblastic versus fibroblastic (chondro vs fibro) analyses. Subtype-specific genes are genes that are either both upregulated or both downregulated in the subtype of interest in the different comparisons.
