MicroRNAs differentially overexpressed in ALDH1 (+) cells compared with ALDH1 (−) cells. A. Hierarchical clustering of miRNA expression profiles by miRNA microarray. Unsupervised hierarchical clustering analysis of miRNAs that exhibited a statistically significant (p < 0.05) increase or decrease in ALDH1 (+) cells compared to ALDH1 (−) cells. The miRNA expression level is color-coded. B. Validation of candidate miRNAs expression by qRT-PCR. The bar graph shows the expression of each microRNA in flow cytometry-sorted ALDH1 (+) cells relative to the average expression level in ALDH1 (−) cells. Representative experiments repeated three times (*p < 0.05).
