Figure 2. Correlation between expressions of clusters-special genes and functional gene sets and previously-identified marker genes of subpopulation of chondrocytes. (A) The heatmap of enriched pathways in clusters by GSVA. (B) The bubble chart of correlations between clusters-special genes and previously-identified marker genes of subpopulation of chondrocytes. (C) The heatmap of correlations between subpopulation of chondrocytes and constructed gene sets.
