Figure 4: Expression profiles of miRNAs detected by dd-PCR. Bars: changes in miRNAs expression in Sca-1+CD31 cells versus Sca-1+CD31+ cells. Expression was normalized to miRNA U6 and expression change was calculated based on the mean of three biological replicates. Bars above and below the -axis: upregulated and downregulated miRNAs in Sca-1+CD31 cells. Differences were analyzed with Student’s -test. , , and .
