Figure 4From: Generation of diverse neuronal subtypes in cloned populations of stem-like cellsActivation of region-specific genes is turned on after the onset of neural differentiation. RT-PCR analyses on the expression of otx2, emx2, dlx2, hox2b region-specific, ngn2, mash1 proneural and math2 neuron-specific genes, in non-induced (d0; st1) and in neuron-enriched (d15, d4, st4) cultures of R1 (ES), P19 (EC) and NE-4C (neural stem) cells, respectively.Back to article page
