Figure 3From: High-efficiency transfection of cultured primary motor neurons to study protein localization, trafficking, and functionMagnetofection does not affect motor neuron morphology and survival. Primary motor neurons (2 DIV) were transfected with Lifeact-GFP (A) or pmaxGFP (B) and fixed 1 day (A), or 3 and 5 days (B) after transfection. A. Motor neuron morphology was evaluated using the F-actin probe Lifeact-GFP and compared to rhodamine phalloidin staining. Cell body, dendrites (left) and growth cone (right) did not show any difference between transfected (top panel) and control (bottom) cells. Size bar: 10 μm. B. Surviving motor neurons were scored based on neurofilament (NF) and HB9 staining (left). Representative images are shown (bottom right). Bars represent mean and SEM from 3 independent experiments. One way repeated measures ANOVA, p > 0.05.Back to article page
