ABSTRACT
The wound healing process in rodents (rats and mice) and lagomorphs (rabbits) predominantly relies on wound contraction rather than re-epithelialization and granulation tissue formation. As a result, existing laboratory animal models for wound healing often fail to mimic human wound healing mechanisms accurately. This study introduces a standardized rabbit model with superior translational potential for skin wound healing research. Two full-thickness dermal wounds were created on the posterior dorsal surface of each rabbit using a standard 2 ×2â¯cm² template. One of these wounds was randomly selected to be treated as a contraction-suppressed wound by applying a transparent adhesive elastic bandage. At the same time, the other was retained as a standard full-thickness wound. Wound contraction was measured on 7, 14, 21, 28, and 35 days. Histomorphological evaluation was done on day 35 to evaluate the quality of wound healing. The findings indicate that transparent adhesive elastic bandage prolonged the wound healing time and suppressed wound contraction in rabbits. In addition, the healed contraction-suppressed full-thickness wounds had denser and thicker collagen fibers than the healed standard full-thickness wounds, indicating better collagen fiber deposition. Our model achieved a 100â¯% success rate in maintaining the transparent adhesive elastic bandage in the rabbits. Therefore, we have developed a simple, non-invasive, cost-effective method for preventing wound contraction. Further studies are required to establish the utility of this model for studying wound healing mechanisms and evaluating therapeutic interventions.
