THIS study examined the effect of diabetes on neural regeneration in vitro. Nodose ganglia (NG) with vagal nerve fibers, dissected from streptozotocin-induced diabetic and normal C57BL/6J mice were embedded in collagen gel. After 3 and 7 days in culture, the numbers of regenerating neurites from transected nerve terminals of NG in diabetic mice were significantly greater than those in controls. Although many studies have revealed diabetes-associated impairment in neural regeneration, the results in the present study suggest that experimental diabetes could induce the potential to enhance regenerative capability of vagal sensory nerves after axotomy.
