title: A deficiency of axonal regeneration in C57BL/6J mice.
abstract: Axonal regeneration within peripheral nerves and dorsal spinal roots was investigated in inbred strains of mice with known differences in macrophage recruitment and inflammatory functions. During the second week after sciatic nerve crush, counts of regenerating newly myelinated fibres were significantly lower in C57BL/6J mice than in 4 other strains. After dorsal root crush with or without concomitant sciatic nerve transection to enhance regeneration, fibre counts in roots of C57BL/6J were one-fifth of those in A/J mice. Axonal regeneration is subnormal in C57BL/6J mice but this defect appears not to be linked to known deficiencies in macrophage function.
