MD Biosciences provides advanced wound healing models in rodents and pigs to support every stage of therapeutic development. Rodent models are ideal for early-stage research, while pig models, with their human-like physiology, are optimal for assessing therapeutic efficacy and conducting GLP IND-enabling studies. MD Biosciences also runs chronic wound models, as well as aged and diabetic models, to address the impact of comorbidities on wound healing.
The incisional wound model is designed to study surgical wound healing and tissue repair in both pigs and rodents. This model involves creating a full-thickness incision through the skin and fascia, with the option of muscle retraction to replicate operational wounds. It is commonly used to evaluate the effects of treatments on incision closure and post-surgical pain. Additionally, it is ideal for testing new incision-washing fluids on unsutured wounds, as well as advancements in sutures, pain relievers, and adhesives.
The excisional wound model is used to study tissue regeneration and wound closure in both pigs and rodents. This model involves creating a full-thickness wound by removing all layers of skin and fascia. It is commonly used to evaluate therapies aimed at improving local wound healing, such as a bandage, sponge, biologic, or other intervention.
The burn wound model is used to study thermal injuries and burn healing in both pigs and rodents. This model involves applying controlled heat to create a burn injury. It is utilized to evaluate interventions for burn recovery, including reducing inflammation, promoting tissue regeneration, supporting blood vessel formation, and encouraging nerve-ending growth. Additionally, it is valuable for assessing the effectiveness of new technologies, such as creams, liquids, and other innovations.
The diabetic wound model is used to study impaired healing under diabetic conditions in both pigs and rodents. This model involves creating wounds in a diabetic animal to evaluate treatments aimed at targeting chronic wound healing and addressing complications associated with diabetes.
The figure shows H&E staining from saline (vehicle control)-treated pigs with full-skin incisions on day 14. Figure A illustrates the epidermis (red line), dermis (D), and subcutis (SC). Figure B highlights the presence of a thin, well-defined fibrous scar that spans the dermis and subcutis.
The figure displays wound closure in young versus aged pigs. It shows delayed healing in aged pigs, compared to faster closure in younger pigs.
Pig sensory nerve function closely mirrors human sensory function, particularly in key pain biomarkers such as TRPV1, with comparable silent nociceptor activity and nerve ending density.
Pig skin closely resembles human skin in both structure and permeability. Pig skeletal muscle aligns with human muscle in contractile, metabolic, and morphological characteristics.
Pigs exhibit similarities to humans in their digestive, immune, nervous, and cardiovascular systems, making them predictive models for topical treatments, medical devices, and drug dosing studies.
