The pig as a model for human wound healing

Area of Science:

• Biomedical research
• Dermatology
• Translational medicine

Background:

• Numerous in vitro and in vivo models exist for wound healing research.
• Selection criteria for animal models include cost, availability, and human similarity.
• Small mammals, commonly used, exhibit significant anatomical and physiological differences from humans.

Purpose of the Study:

• To review existing literature on animal models for human wound healing.
• To assess the correlation of various models with human wound healing outcomes.
• To evaluate the suitability of the porcine model for wound healing studies.

Main Methods:

• Comparative literature review of over 180 articles.
• Examination of studies on wound dressings, topical antimicrobials, and growth factors.
• Analysis of anatomical and physiological similarities between porcine and human skin.

Main Results:

• Pig skin exhibits greater anatomical and physiological similarity to human skin compared to small mammals.
• The porcine model has been utilized in studies evaluating therapeutic agents for wound healing.
• Evidence supports the efficacy of the porcine model in predicting outcomes for human wound treatments.

Conclusions:

• The porcine model is a highly suitable animal model for human wound healing research.
• Its anatomical and physiological likeness to humans makes it valuable for testing therapeutic agents.
• The porcine model demonstrates strong correlation for evaluating treatments intended for human wounds.
