Figure 3From: Axonal outgrowth is associated with increased ERK 1/2 activation but decreased caspase 3 linked cell death in Schwann cells after immediate nerve repair in ratsLength of regenerating axons in the distal nerve segment. Axonal outgrowth was evaluated by measuring the length of stained neurofilaments, and the graph shows the length of the neurofilaments (mm) expressed as mean + SD. The stars indicate p-values * < 0.05: *** < 0.001.Back to article page
