This protocol describes the induction of an ischemia-reperfusion (IR) model on mouse ear skin using magnet clamping. Using a custom-built intravital imaging model, we study in vivo inflammatory responses post-reperfusion. The rationale behind the development of this technique is to extend the understanding of how leukocytes respond to skin IR injury.

Athletes absorb several hundred mild traumatic brain injuries (mTBI)/concussions every year; however, the consequence of these on the brain is poorly understood. Therefore, an animal model of single and repetitive mTBI that consistently replicates clinically relevant symptoms provides the means to advance the study of mTBI and concussion.

Source: Richard Glickman-Simon, MD, Assistant Professor, Department of Public Health and Community Medicine, Tufts University School of Medicine, MA This video describes the examination of the ear, beginning with a review of its surface and interior anatomy (Figure 1). The cartilaginous auricle consists of the helix, antihelix, earlobe, and tragus. The mastoid process is positioned just behind the earlobe. The slightly curving auditory canal ends at the tympanic membrane, which transmits sound...

FAQs
It allows investigators to examine separate responses in sensory hair cells, supporting cells, and neural pathways after damage. Comparing these tissues can reveal how injury progresses through cellular damage, inflammation, degeneration, and attempted repair. This mechanistic resolution helps connect microscopic changes with hearing or balance dysfunction and identifies biological processes that protective or regenerative treatments may target.
Cochlear damage primarily relates to hearing function, whereas vestibular damage relates to balance and dizziness. An experimental model can therefore be organized around the affected sensory system and its corresponding functional outcome. Separating these domains helps researchers determine whether an intervention protects auditory pathways, vestibular tissues, or both, rather than treating all inner ear injury as a single response.
Tissue findings show which cells and pathways are affected, while functional assessments indicate whether those changes alter hearing or balance. Using both types of evidence provides a more complete interpretation of injury severity and recovery. This relationship is important when judging whether a treatment merely changes tissue appearance or produces meaningful improvement in sensory function.
A typical workflow begins with controlled exposure to a damaging condition or another method that simulates injury. Investigators then examine cochlear or vestibular tissues, including hair cells, supporting cells, and neural pathways, and assess auditory or vestibular function. Comparing injured and treated conditions can reveal injury mechanisms, recovery patterns, and treatment-related protection or repair.
Researchers can use the injury platform to test protective drugs, regenerative treatments, and gene-based therapies under controlled experimental conditions. Outcomes may include changes in cellular damage, inflammation, degeneration, repair, hearing, or balance. This makes the model useful for preclinical comparison of interventions before researchers determine whether an approach merits further development for related disorders.
These models provide experimental context for hearing loss, tinnitus, dizziness, and related hearing or balance disorders. Their value extends beyond reproducing symptoms because they connect functional problems with changes in sensory cells and neural pathways. In medicine, that connection supports investigation of disease mechanisms and the development of interventions aimed at protection, regeneration, or gene-based repair.
