Fig. 3. Expression of Fyn^R176A mutant induced the branching of cortical neurons. The brains were transfected with GFP or Fyn^R176A at E15.5 and analyzed at E18.5. (A, A’) Normal morphology of migratory neurons in the GFP control group. (B, B’) Branching of cortical neurons in the Fyn^R176A group. (C) Ratio of neurons with branches in the Fyn^R176A mutant group compared with the GFP control group. Bars represent means ± standard deviation (*P < 0.05). (A, B) Scale bar = 100 μm, (A’ and B’) Scale bar = 10 μm.
