Figure 3. Changes in RGC axons and dendrites after transfection with Sema3A siRNA. A: Treatment with siRNA Sema3A and control siRNA for 120 h promoted the growth of RGC axons and inhibited the growth of dendrites. Scale bar, 40 μm. B: The longest axon and dendrite per RGC were measured after transfection with Sema3A siRNA at 120 h of culture. C: The percentage of bipolar cells was measured in Sema3A siRNA-treated RGCs after 120 h (mean ± SD; 37-71 cells per treatment, *p<0.05 compared to control siRNA).
