PPIA, HPRT1, and YWHAZ Genes Are Suitable for Normalization of mRNA Expression in Long-Term Expanded Human Mesenchymal Stem Cells

Figure 5

Application for normalization of the most stable reference genes. OCT4 gene expression level in long-term expanded BM-MSCs was normalized using most stable RGs (PPIA, HPRT1 and YWHAZ) validated by geNorm and NormFinder, and two traditional RGs (GAPDH and ACTB) to demonstrate the effect of validated RGs on normalization of gene of interest. The data were presented as mean ± SD. P < 0.05 vs E-BM-MSCs.
