We describe protocols for our mouse graft arteriosclerois (GA) models which involve interposition of a mouse vessel segment into a recipient of the same inbred strain. By backcrossing additional genetic changes into the vessel donor, the model can assess the effect of specific genes on GA.

Two basic types of preparation are used to visualize specimens with a light microscope: wet mounts and fixed specimens. The simplest type of preparation is the wet mount, in which the specimen is placed in a drop of liquid on the slide. A liquid specimen can be directly deposited on the slide using a dropper. Solid specimens, such as skin scraping, can be placed on the slide before adding a drop of liquid to prepare the wet mount. Sometimes the liquid is simply water, but stains are often added...

A Technique for Human Skin Grafting in a Mouse Model

This video demonstrates a method for grafting human skin onto an immunodeficient mouse with a suppressed neutrophil response. The method involves applying human split-thickness skin to the mouse's graft bed, sealing it, and covering it for recovery. Eventually, the human skin adheres to the mouse's skin, establishing vascularization and circulation, resulting in a successful skin xenograft.

Fluorescence in-situ hybridization (FISH) is often required in combination with histopathology and molecular diagnostics for selection of therapy in personalized medicine. A novel non-cross-linking, formalin-free tissue fixative that allows high quality morphologic, molecular and FISH analyses from the same specimen by addition of a post-fixation step before FISH is presented.
FAQs
Effective fixation stabilizes the graft and preserves close contact with the recipient site while healing begins. This restraint helps prevent displacement that could interrupt tissue attachment or compromise the intended anatomical position. By maintaining stability during this vulnerable period, fixation supports the conditions needed for vascular and cellular integration and lowers the likelihood of graft failure.
Vascular and cellular integration help the graft become established within the recipient site rather than remaining mechanically supported only. Proper fixation contributes by maintaining graft position and contact during early healing, when unwanted movement could interfere with these processes. The quality of this integration affects whether the repaired or reconstructed tissue can develop stable structure and function.
These options provide different ways to stabilize a graft, but the appropriate choice depends on the procedure and the tissue being repaired. Sutures and anchors secure tissue, screws provide fixation in relevant reconstructive settings, and tissue adhesives bond graft material to the recipient site. Their shared purpose is to maintain position and contact while healing proceeds.
Fixation planning should account for the graft’s intended anatomical position, the need to restrict unwanted movement, and the requirement for sustained contact with the recipient site. The selected device or material should also suit the surgical context, such as ligament reconstruction, skin grafting, or bone repair. These considerations influence integration, recovery, and the risk of displacement.
A fixation procedure places the graft in its intended anatomical position, selects a suitable securing method, and stabilizes the tissue so it remains in contact with the recipient site during early healing. Depending on the operation, the surgeon may use sutures, screws, anchors, or tissue adhesives. The desired outcome is stable positioning that supports integration and function.
Graft fixation is used across reconstructive procedures in which transplanted or engineered tissue must remain stable while healing. Examples include ligament reconstruction, skin grafting, bone repair, and other surgeries intended to restore tissue structure or function. Although the anatomical setting differs, each application depends on maintaining graft position long enough for healing and integration to occur.
