Fig. 2From: Membrane-enriched proteome changes and prion protein expression during neural differentiation and in neuroblastoma cells a-d) Quantitative mRNA expression of different markers during ES cells differentiation (0, 3, 6, 9 days). a) Oct4, b) Nanog, c) Sox1 and d) Nestin. Pairwise t-tests were performed to calculate significant differences compared to ES cells (*p < 0.05, **p < 0.01, ***p < 0.001)Back to article page
