Fig. 1From: Identifying the key genes regulating mesenchymal stem cells chondrogenic differentiation: an in vitro studyStudy design and heatmap showing all DEGs. A The expreimental procedure of this study. B The expression of chondrogenic marker COL2A1 in chondrocyte pellet after induced for 7, 14, and 21 days were assessed by IHC. C The correlation coefficient between different biological replicates and indicated time points. MSCs = undiferentiated MSCs, C7 = induced chondrogenesis for 7 days, C14 = induced chondrogenesis for 14 days, C21 = induced chondrogenesis for 21 days, CHO = mature chondrocytes. D Heatmap showing all DEGs. The expression values are |log2 fold changes|≥ 1 and P ≤ 0.05Back to article page
