Figure 3C illustrates 11 enriched pathways involved in the chondrogenic differentiation of BMSCs mediated by collagen hydrogel, including Focal adhesion, Regulation of actin cytoskeleton, Protein digestion and absorption, Dilated cardiomyopathy, ECM-receptor interaction, Hypertrophic cardiomyopathy, Proteoglycans in cancer, Propanoate metabolism, PI3K-Akt signaling pathway, Wnt signaling pathway and Valine, leucine and isoleucine degradation. Here, AKT1 is linked to hypertrophic cardiomyopathy.
