Figure 5: Expression profiles of genes detected by dd-PCR. Bars: difference changes in expression in Sca-1+CD31 cells versus Sca-1+CD31+ cells. Expression was normalized to GAPDH and the expression change was calculated based on a mean of three biological replicates. Bars above and below the -axis show upregulated and downregulated genes in Sca-1+CD31 cells. Differences were analyzed with Student’s -test. , , and .
