The results of real-time PCR analysis.

<p>Expression of each gene in each analyzed sample was firstly normalized to cDNA from all analyzed samples (pooled cDNA) and compared to normalized expression in BJ fibroblasts (SOX2, MSI1, nestin) and iPSCs (NKX2.2). The p-value was indicated in the selected samples (* p < 0.05; ** p < 0.01; *** p < 0.001; SEM), all statistical data are summarized in <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0141688#pone.0141688.s004" target="_blank">S4 Table</a>.
