The goal of this protocol is to establish an orofacial muscle fibrosis model. Comparison of the histology between mice masseter and tibialis anterior muscle after freezing injury confirmed masseter muscle fibrosis. This model will facilitate further investigation into the mechanism underlying orofacial muscle fibrosis.

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.

2011
Lateral fluid percussion (LFP), an established model of traumatic brain injury in mice, is demonstrated. LFP fulfills three major criteria for animal models: validity, reliability and clinical relevance. The procedure, consisting of surgical craniotomy, fixation of hub followed by induction of injury, resulting in focal and diffuse injuries, is described.
FAQs
Damage begins when ice crystals form within and around cells. Intracellular and extracellular ice can disrupt membranes, alter tissue structure, and interfere with local blood flow. These linked changes provide measurable routes from cold exposure to cellular injury and tissue dysfunction, helping researchers connect physical freezing effects with biological outcomes.
Thawing is not simply a return to normal temperature. The post-thaw phase can intensify inflammation and cell death, so injury assessment must consider responses after freezing as well as the initial cold event. This makes the model useful for examining how early damage progresses into later tissue degeneration or repair.
Control over freezing conditions is central to the model’s experimental value. By reproducing cold injury in a controlled biological setting, researchers can compare treatments under consistent conditions rather than relying only on variable, uncontrolled exposure. These comparisons help distinguish effects associated with injury from changes linked to a proposed intervention.
A typical experimental workflow applies a defined subzero exposure to biological tissue, permits thawing, and then examines injury and recovery. The design can compare untreated or differently treated conditions, provided the freezing and post-thaw phases remain controlled. This organization links the exposure protocol to cellular damage, inflammatory responses, degeneration, or regeneration observed afterward.
Researchers can examine inflammatory signaling, tissue degeneration, and regeneration after cold injury. Together, these outcomes reveal whether tissue responses remain associated with ongoing damage or include repair-related changes. The model therefore supports investigation of cellular and molecular responses, not merely visible structural injury, and helps relate local tissue changes to broader mechanisms of repair.
Its applications include studying tissue repair, cryoinjury, and cold-related disease. Because exposure conditions are controlled, the system can support comparisons among treatments and help clarify why tissues degenerate, signal inflammation, or regenerate after freezing. This makes it relevant to biology questions that connect experimental injury with repair mechanisms and disease-related tissue damage.
