Table 2  Genes differentially expressed in the neurosphere vs. differentiated cells comparison (F-G).  Genes with p < 0.001, calculated by empirical Bayes moderated t-test and false discovery rate adjustment, and fold change ≥ 4 (-2 ≥ M ≥ 2), are included. Genes with M-value < 0 are up-regulated in differentiated cells, genes with M-value > 0 are up-regulated in neurospheres. M = log2(Cy5/Cy3), B = B-value calculated by empirical Bayes moderated t-test. Higher B-values mean higher probability for differential expression.
