No difference between sensory and mixed motor nerves in number of regenerating axons, axon diameter, axon area, or myelin area in distal stump (p > 0.05). (a) number of regenerating axons per 100 μm2 of nerve area, (b) mean axon diameter, (c) mean axon and myelin area. Asterisk (*) indicates significant difference between denervated group (D) and immediate repair (IR) or sensory protected (SP), post hoc Tukey test p < 0.05. Number of animals: IR n = 5, SP n = 5, and D n = 4. Error bars represent SEM.
