Herein, we present a protocol to use heat shock protein 27 (HSP27)-specific small interfering RNA to assess the function of HSP27 during corneal epithelial wound healing. RNA interference is the best method for effectively knocking-down gene expression to investigate protein function in various cell types.

This protocol focuses on damaging the ocular surface of zebrafish through abrasion to assess the subsequent wound closure at the cellular level. This approach exploits an ocular burr to partly remove the corneal epithelium and uses scanning electron microscopy to track changes in cell morphology during wound closure.

FAQs
Epithelial repair follows a coordinated sequence: cells first spread and migrate across the exposed surface, then proliferate to restore an intact layer. Migration provides rapid coverage, while proliferation replenishes the cell population needed for sustained repair. This sequence helps re-establish the corneal surface after injury and supports preservation of transparency and vision.
Inflammatory signals help recruit immune cells to the injured cornea and activate stromal keratocytes, the resident cells of the stromal layer. These responses connect surface injury with deeper tissue repair. Their activity is important for coordinating healing, but treatment research also considers how repair-related responses may contribute to scarring or haze that can impair vision.
Restoring the cornea requires more than closing the epithelial surface. Extracellular matrix remodeling helps re-establish tissue structure, while endothelial responses support fluid balance within the cornea. Together, these processes influence whether the repaired tissue preserves the organization and optical properties needed for transparency and clear vision.
The cornea contains epithelial, stromal, and endothelial layers, and injury to each engages different repair-related responses. Surface damage emphasizes epithelial migration and proliferation, whereas deeper injury also involves keratocyte activation and matrix remodeling. Endothelial involvement is relevant to fluid balance, so the affected layer helps determine which aspects of healing require attention.
Understanding the repair sequence helps explain how the cornea responds to abrasions, ulcers, and injuries created during surgery. It provides a framework for considering whether epithelial coverage, stromal organization, or endothelial function needs support. The same knowledge also helps clinicians and researchers focus on outcomes such as preserved transparency, reduced haze, and maintained vision.
Research on contact lenses and wound-healing therapies can examine whether interventions support tissue repair while limiting undesirable consequences. Relevant outcomes include restoration of corneal structure, preservation of transparency, maintenance of fluid balance, and reduction of scarring or haze. These measures connect biological healing responses with the visual function that treatment aims to protect.
