Screening of differentially expressed miRNAs in UC-hMSCs. (A) The diagram showed the number of down-regulated miRNAs in high-osteogenic UC-hMSCs and low-osteogenic UC-hMSCs. (B) The heatmap diagram showed the results of the two-way hierarchical clustering of miRNAs. Each row represents one miRNA, and each column represents a sample. The color scale illustrates the relative expression level of a miRNA across all samples: green represents an expression level above the mean, and red represents an expression lower than the mean.
