Intra-epidermal nerve fibre (IENF) density after chronic constriction injury of the mental nerve. The number of nerve fibres that originated from, or crossed, the basement membrane were counted in 10 μm parasagittal sections that were immunolabelled for protein gene product 9.5 (PGP 9.5), Tropomyosin-related kinase A (TrkA) and Calcitonin gene-related peptide (CGRP).
