A precise murine model for acute kidney injury (AKI) due to ischemia is an important tool to investigate acute kidney injury and possibly find therapeutic tools to treat renal injury. The hanging weight system offers a tool for immediate and reliable renal artery occlusion and reperfusion without causing renal congestion.

We present a preparation for visualizing and manipulating calcium signaling in native, intact microvascular endothelium. Endothelial tubes freshly isolated from mouse resistance arteries supplying skeletal muscle retain in vivo morphology and dynamic signaling within and between neighboring cells. Endothelial tubes can be prepared from microvessels of other tissues and organs.

The surgical procedure used to induce experimental myocardial infarction in mice begins with left thoracotomy between the third and the fourth ribs in order to visualize the anterior surface of the heart and left lung. The left coronary artery is ligated, the chest is closed and the mouse is allowed to recover spontaneously.

FAQs
Preserving the vessel wall maintains the structural context needed to examine vascular function and immune responses directly. Damage introduced during separation could complicate interpretation of endothelial barrier changes, leukocyte adhesion, or inflammatory signaling. Careful handling therefore supports more meaningful microscopy, molecular assays, and comparisons between experimental conditions involving vascular inflammation or pathogen-associated injury.
When the lumen remains intact, the isolated vessel can support perfusion or other downstream analyses that depend on access to the internal vascular space. This feature helps investigators examine responses in a more controlled vessel preparation while retaining the artery’s relationship between its wall and lumen. Whether lumen preservation is required depends on the planned experiment.
This preparation can separate vessel-specific effects from broader systemic responses. Researchers can examine leukocyte adhesion, inflammatory signaling, endothelial barrier changes, and pathogen-associated vascular injury within the isolated artery itself. That controlled perspective is useful when determining whether an observed vascular response reflects a direct change in the vessel or an indirect consequence of whole-system inflammation.
The procedure relies on careful dissection under sterile conditions, with attention to preserving the vessel wall and, when needed, keeping the lumen available for perfusion or subsequent analysis. These handling priorities protect the preparation’s usefulness for structural, functional, immunological, and infection-related studies. The specific endpoint determines how much emphasis is placed on wall or lumen preservation.
After isolation, investigators may apply microscopy, molecular assays, pharmacological testing, or other downstream analyses supported by the preparation. These approaches can characterize vascular structure, inflammatory signaling, leukocyte adhesion, endothelial barrier changes, and pathogen-associated injury. Using several readouts allows structural observations to be considered alongside functional or molecular changes in the same research context.
Isolated arteries provide a controlled setting for evaluating pharmacological interventions aimed at vascular inflammation. Researchers can assess how a treatment affects vessel-associated immune responses, endothelial barrier changes, or pathogen-related injury without relying only on systemic measurements. This makes the preparation relevant for comparing treatment conditions and examining whether therapeutic effects are linked specifically to vascular tissue.
