Wound Healing Model - Excisional Wound

The full-thickness wound in db/db mouse and in alloxan treated rats are two models of impaired wound healing in diabetes mellitus.

Delayed wound closure in db/db mice is due to impairment of wound contraction, as well as delayed formation and maturation of granulation tissue.

The rate of re-epithelialization is the same as in wild type mice.

The wide range of different read-outs permits a more precise differentiation of effects of novel therapeutic agents on the wound healing process.
