Previous studies focused on the effects of sympathetic denervation with
6-hydroxydopamine (6-OHDA) on nondiabetic wounds, but the effects of 6-OHDA on
diabetic wounds have not been previously reported. In this study, treated mice
received intraperitoneal 6-OHDA, and control mice received intraperitoneal
injections of normal saline. Full-thickness wounds were established on the backs
of mice. The wounds were sectioned (four mice per group) for analysis at 2, 5, 7,
10, 14, 17, and 21 days after injury. The wound areas in the control group were
larger than those in the treatment group. Histological scores for epidermal and
dermal regeneration were reduced in the 6-OHDA-treated group on day 21. The mast
cells (MCs) in each field decreased after sympathectomy on days 17 and 21. The
expression levels of norepinephrine, epidermal growth factor (EGF), interleukin-1
beta, NG2 proteoglycan, and desmin in the treatment group were less than those in
the control group. In conclusion, 6-OHDA delays reepithelialization during wound
healing in diabetic mice by decreasing EGF, but increases wound contraction by
reducing IL-1? levels and the number of MCs. Besides, 6-OHDA led to reduced
pericyte proliferation in diabetic wounds, which might explain the vascular
dysfunction after sympathetic nerve loss in diabetic wounds.
