Porcine corneal ex vivo organ culture and epithelial wound healing provide an economical, ethical, reproducible, and quantitative means for testing the ocular toxicity of chemicals. They also aid in elucidating mechanisms underlying the regulation of epithelialization and tissue repair, and in evaluating therapeutics for treating diabetic keratopathy and delayed wound healing.

Chronic wounds that are resistant to antibiotics are a major threat to the healthcare system. Biofilm infections are stubborn and hostile and can cause deficient functional wound closure. We report a clinically relevant swine model of biofilm-infected full-thickness chronic wounds. This model is powerful for mechanistic studies as well as for testing interventions.

This protocol describes a method to inflict an abrasion to the ocular surface of the mouse, and to follow the wound healing process thereafter. The protocol takes advantage of an ocular burr to partially remove the surface epithelium of the eye in anaesthetized mice.
FAQs
Layered architecture provides a more physiologically relevant context for examining how corneal cells respond to injury. Tissue organization can influence cell migration, proliferation, matrix remodeling, and re-epithelialization, while biochemical signals help coordinate these processes. This structure allows bioengineers to study repair responses that may not be represented adequately in simpler laboratory systems.
A defined wound creates a consistent starting point for tracking several parts of the repair response. Researchers can monitor how cells migrate into the injured region, proliferate, remodel the surrounding matrix, and restore epithelial coverage. Examining these processes separately helps reveal whether a material or treatment affects early movement, cell expansion, matrix changes, or re-epithelialization.
The biomaterial or extracellular matrix scaffold provides structural support for the corneal cells and helps recreate aspects of the tissue environment. Its properties can be evaluated for effects on wound repair and matrix remodeling. Comparing scaffold-based systems enables bioengineers to investigate materials intended for corneal implants or regenerative strategies under controlled culture conditions.
A typical workflow combines corneal cells with a selected biomaterial or extracellular matrix scaffold, establishes the engineered tissue, and introduces a defined wound. The construct is then maintained under controlled culture conditions while researchers follow migration, proliferation, matrix remodeling, and epithelial restoration. This sequence links the initial injury to measurable repair outcomes.
Researchers can use the model when they need to assess how biomaterials, therapeutics, or regenerative strategies influence corneal wound repair in a controlled setting. Because the system reproduces tissue architecture and injury responses, it provides a platform for comparing interventions based on their effects on cell behavior, matrix remodeling, and re-epithelialization before further development.
By revealing how tissue architecture, biomaterials, and biochemical signals shape healing, the model can guide the design of corneal implants and regenerative approaches. It also offers a controlled way to examine repair responses relevant to individual treatment strategies. In bioengineering research, these capabilities help connect engineered tissue behavior with clinically oriented design decisions while reducing reliance on animal studies.
