Porcine Ex vivo Cornea Model of Bacterial Keratitis: A Technique to Establish Bacterial Infection in Corneal Epithelial Cells

2025
This video describes a protocol to set up an ex vivo model for bacterial keratitis using a corneoscleral button dissected from the porcine eye. Inoculated bacteria traverse the corneal epithelial incisions to invade the underlying stroma and establish an infection within the corneal tissues that mimic the in vivo infection.

Endothelial corneal transplantation is a surgical technique for treatment of posterior corneal diseases. Mechanical microkeratome dissection to prepare tissue results in thinner, more symmetric grafts with less endothelial cell loss and improved outcomes. Dissections can be performed at the eye bank prior to corneal transplantation surgery.

Here, a step-by-step protocol for the preparation and cultivation of porcine split corneal buttons is presented. As this organo-typically cultivated organ culture model shows cell death rates within 15 days, comparable to human donor corneas, it represents the first model allowing long-term cultivation of non-human corneas without adding toxic dextran.

FAQs
The epithelial surface acts as an initial physical and immunological barrier, limiting exposure of deeper tissue to external challenges. Beneath it, the stroma provides the site into which inflammatory cells can be recruited after immune activation. Examining these compartments together helps researchers relate barrier status to deeper inflammatory changes rather than treating corneal infection as a single uniform tissue response.
When injury or microbial invasion disrupts the corneal environment, innate immune signaling can become activated. This response is associated with cytokine release and recruitment of inflammatory cells into the underlying stroma. Studying these linked events allows investigators to connect an initial barrier challenge with downstream inflammation and tissue damage, helping clarify host responses during ocular infection.
Their organized tissue structure and physiological similarity to human corneas make them useful for examining how ocular tissue responds to microbial invasion. In immunology and infection studies, investigators can connect pathogen-related challenge with epithelial barrier effects, innate immune signaling, cytokine release, inflammatory-cell recruitment, and tissue damage. This supports biologically relevant evaluation of infection-related tissue responses.
An ex vivo approach provides a controlled setting for examining corneal responses to injury or microbial invasion while focusing on tissue-level events. Investigators can study wound healing, antimicrobial responses, and inflammatory changes under controlled experimental conditions. This makes the tissue useful for linking a defined challenge to observable changes in ocular biology and host defense.
Because the tissue supports evaluation of therapeutic strategies and corneal repair approaches, researchers can use it to examine responses relevant to infection, injury, and healing. Its structural and physiological similarities to the human cornea strengthen its value as a translational model. Findings can help characterize how candidate approaches relate to tissue damage, antimicrobial responses, or restoration after injury.
Studies can reveal how a corneal barrier challenge is associated with innate immune activation, cytokine release, inflammatory-cell recruitment, and tissue damage. They can also address whether tissue responses include wound-healing or antimicrobial activity under experimental conditions. Considering these outcomes together gives a broader picture of host defense and pathology than focusing on microbial invasion alone.
