The Pig as a translational model for wound healing
MD Biosciences offers various models of wound healing in both rodents and pigs. Skin wound healing is a complex biological process activated by signaling pathways of epithelial and non-epithelial cells, which release a myriad of cytokines and growth factors. While rodent models provide data for earlier research stages, pig models are ideally suited for wound healing efficacy studies. Perhaps one of the most compelling arguments for use of pigs in wound healing studies is the similarity in the physiological processes through which pig and human heal. Pig and human close partial-thickness wounds primarily through re-epithelialization, rather than wound contraction as is the case with small animals such as rodents. Impaired wound healing can also be evaluated by using a diabetic animal.
Inflammatory biomarkers provide information related to mechanisms contributing to inflammatory pain and how well compounds modulate the inflammatory and/or pain response.
