Real time qPCR results of PAX6, NEUN, NESTIN, CSTB gene expression levels in PAX6- and NEUN- FACS sorted nuclei from f-CTRL d135 hCOs. Data are represented as mean ± SEM. Statistical significance was based on T-student test (*P < 0.05, **P < 0.01). For PAX6, 10 samples were analyzed as biological replicates: 5 for Pax6+sorted Nuclei and 5 for Neun+sorted Nuclei; for NEUN, NESTIN and CSTB, 9 samples were analyzed as biological replicates: 5 for Pax6+sorted Nuclei and 4 for Neun+sorted Nuclei.
