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 article provides a detailed and visual description of a methodology for collecting and measuring biochemical inflammatory and nociceptive mediators at the surgical wound site following cesarean delivery. This human bioassay has been used to determine correlations between wound and serum cytokine concentrations and drug-mediated changes in wound cytokines, chemokines and neuropetides.

Electrical Penetration Graph (EPG) is a well-established technique for studying the feeding behavior of stylet-bearing insects. Here we show a new application of EPG as a non-invasive tool for the acquisition of intracellular electrophysiology recordings of sieve elements (SEs), the cells that form the phloem vasculature in plants.

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
Voltage or current establishes the electrical stimulus, while pulse duration determines how long the material, cells, or tissue experiences it. Changing either parameter can alter the resulting injury and may favor membrane disruption, electrochemical changes, or localized heating. Researchers therefore treat these variables as controllable experimental conditions when comparing wound responses across samples.
Electrode arrangement influences how electrical energy is distributed across the target region. Because the injury must be localized and reproducible, the electrode configuration is an important part of the experimental design rather than a minor setup detail. Differences in arrangement can change the affected area and the electrical conditions experienced by cells or tissues.
The surrounding medium is one of the variables that determines how an applied electrical stimulus produces damage. Depending on the combined electrical conditions and medium, the response may include membrane disruption, electrochemical changes, or localized heating. Controlling this environment helps researchers distinguish biological responses to the wound from effects caused by inconsistent experimental conditions.
A basic workflow establishes the target material, cells, or tissue, places the electrodes in a defined arrangement, and applies a selected voltage or current for a specified pulse duration. The surrounding medium is kept consistent, after which the localized response can be examined. Recording these conditions allows wound closure, migration, or repair responses to be compared between experiments.
Researchers can use Electrical Wounding when they need a standardized way to compare how materials, cells, or tissues respond to damage. The controlled electrical parameters create a localized injury under defined conditions, supporting measurements of wound closure, cell migration, and tissue repair. This reproducibility is especially useful for studying how changes in the experimental system influence recovery.
Beyond tracking physical wound closure, the approach supports investigations of bioelectric signaling, meaning biological responses associated with electrical conditions. Findings from these controlled injury models may help inform strategies for electrical stimulation in regenerative medicine and wound-care technologies. The method therefore connects biophysical studies of repair with efforts to understand or influence tissue recovery.
