Figure 7From: Critical role of p38 MAPK for regeneration of the sciatic nerve following crush injury in vivo Western blot analysis. Protein lysates extracted from sciatic nerves from both wt (p38+/+) and sem (p38+/−) mice were examined by western blotting for TNF-α and IL-1β expression at three days and four weeks following crush injury. Expression at each time point (n = 3 samples per group) were analyzed and quantified as relative density against control.Back to article page
