Source: Macheda, T., et. al. Electromagnetic Controlled Closed-Head Model of Mild Traumatic Brain Injury in Mice. J. Vis. Exp. (2022)This video demonstrates the procedure to induce a closed-head injury in a mouse model using a stereotaxic frame. The controlled impact replicates mild traumatic brain injury, allowing researchers to study neurological effects and recovery by measuring post-injury reflexes and behavior.

The isolated rat heart is an enduring model for ischemia reperfusion injury. Here, we describe the process of harvesting the beating heart from a rat via in situ aortic cannulation, Langendorff perfusion of the heart, simulated ischemia-reperfusion injury, and infarct staining to confirm the extent of ischemic insult.

Induction of Traumatic Brain Injury in a Rat Model Using a Lateral Fluid Percussion Device

2025
This video demonstrates the induction of traumatic brain injury (TBI) in a rat using a lateral fluid percussion injury (FPI) device. The procedure involves creating a hole in the skull of an anesthetized rat to expose the dura mater, onto which a cannula is attached. The rat is then connected to the device, which generates a pressure wave that reaches the brain, mimicking TBI by causing neural cell death and vascular...
FAQs
The immediate breach disrupts local tissue architecture, creating a site where biological responses can develop. Depending on the tissue and experimental conditions, the injury may initiate bleeding control, inflammatory signaling, cellular migration, and matrix remodeling. These processes provide measurable endpoints for studying how biological or engineered systems respond to localized damage.
Puncture size, depth, and location determine the extent and position of architectural disruption. If these parameters vary between samples, differences in healing may reflect inconsistent injury rather than the treatment or construct being tested. Standardizing them improves reproducibility and supports meaningful comparisons across treatments, tissue-engineered designs, or experimental groups.
The same localized injury can produce different responses because outcomes depend on the tissue and the surrounding experimental conditions. Bleeding control, inflammatory signaling, cellular migration, and matrix remodeling may therefore vary in prominence. Accounting for these influences helps researchers interpret recovery patterns without assuming that every model responds identically.
Before creating the injury, researchers should establish the instrument or probe to use and define the intended puncture size, depth, and location. Applying these parameters consistently creates a controlled injury site. The resulting system can then be examined for recovery-related responses under the selected biological or engineered experimental conditions.
In bioengineering, this approach is useful when researchers need to evaluate wound-healing responses in biological or engineered systems. It supports testing of biomaterials and tissue-engineered constructs by providing a localized injury against which recovery can be assessed. The method can reveal how a design responds after its structure has been mechanically disrupted.
Comparisons can show whether different treatments or tissue-engineered designs support distinct recovery responses after a standardized injury. Researchers may examine processes such as bleeding control, inflammatory signaling, cellular migration, or matrix remodeling, depending on the model. Consistent injury parameters make observed differences more interpretable and help link outcomes to the tested intervention or design.
