Figure 3: Combinatorial actions of GFs and Neurog2.

(a–c) The numbers of total GFP⁺ (a), GFP⁺/Dcx⁺ (b) and GFP⁺/NeuN⁺ (c) cells detected at different time points after GF/virus infection (mean±s.d., n=3–4 animals). The number of GFP⁺ cells in GF-untreated animals is shown in Supplementary Table S1. *P<0.01 compared with control viruses in Student’s t-test. (d,e) The estimated numbers of GFP⁺/Dcx⁺ (left) and GFP⁺/NeuN⁺ (right) cells in the striatum (d) and neocortex (e) under various conditions (mean±s.d., n=3–4 animals). The numbers in parentheses show the percentage of GFP⁺/NeuN⁺ cells at DAI-14 compared with GFP⁺/Dcx⁺ cells at earlier time points. *P<0.01 compared with control viruses in Student’s t-test; $P<0.01 compared with GFs or Neurog2 alone in Student’s t-test. ND, not detected.
