Source: Zimmermann, S., et.al. Stromal Vascular Fraction-enriched Fat Grafting for the Treatment of Symptomatic End-neuromata. J. Vis. Exp. (2017)This video demonstrates the surgical procedure for neurolysis and stromal vascular fraction (SVF)-enriched fat grafting in the management of symptomatic neuroma. Neurolysis removes adhesion tissue to restore nerve gliding, while SVF-enriched fat grafting is applied around the nerve to create a protective barrier, support nerve healing, and enhance...

This study investigated the antifouling activity of artificial lung hollow fibers coated by priming the lung device. While this surface modification of fibers approach is practical, the effectiveness of the coating process depends on the graft coverage across fiber mat layers within the bundle.

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.

Here we present a protocol describing oxygenated ex situ machine perfusion of donor liver grafts. This article contains a step by step protocol to procure and prepare the liver graft for machine perfusion, prepare the perfusion fluid, prime the perfusion machine and perform oxygenated normothermic machine perfusion of the liver graft.
FAQs
Cell adhesion helps the graft attach to neighboring tissue, while extracellular-matrix remodeling reorganizes the surrounding structural network during healing. These processes allow the implanted material or cells to become integrated rather than remaining mechanically isolated. Their coordination contributes to stable incorporation and helps the repaired region respond to local biological and mechanical conditions.
Vascularization, the development or connection of blood supply, supports the local conditions needed for graft incorporation and healing. A graft with inadequate access to blood supply may not integrate effectively with surrounding tissue. For this reason, blood supply is evaluated alongside compatibility and structural support when assessing whether an In Situ Grafting approach can succeed.
The host immune response influences whether the graft becomes incorporated or encounters conditions that limit healing. Controlled responses can coexist with the adhesion, vascularization, and matrix-remodeling processes required for repair, whereas poorly controlled responses may interfere with integration. Managing this biological interaction is therefore central to developing graft-based therapies and tissue-engineering strategies.
Mechanical and biochemical signals provide local cues that influence how a graft interacts with its surroundings during healing. Mechanical conditions relate to structural support, while biochemical cues affect cellular and tissue responses. Together, these signals help guide incorporation and remodeling, making the local repair environment an important determinant of graft performance.
Planning should account for graft compatibility, available blood supply, structural support, and the host response. These factors are interconnected: compatibility affects biological interaction, blood supply supports healing, structural support helps maintain the repair site, and controlled host responses promote incorporation. Considering them together helps researchers evaluate whether the approach is appropriate for a particular tissue-repair objective.
Applications described for this approach include repair of damaged skin, bone, blood vessels, and other tissues. The choice of graft material and the required support depend on the biological and structural demands of the target site. This flexibility makes the technique relevant to tissue engineering and to the development of therapies intended to promote localized repair.
A general workflow begins by selecting compatible donor tissue, cells, or graft material and identifying the region requiring repair. The graft is then placed at that site, where local adhesion, blood-supply development, immune responses, matrix remodeling, and mechanical or biochemical signaling influence healing. Researchers assess incorporation in relation to these interacting conditions.
The approach provides a framework for studying repair within the tissue environment where healing must occur. Researchers can examine how grafts interact with surrounding cells, blood supply, extracellular matrix, immune responses, and structural conditions. This makes it useful for developing regenerative strategies and evaluating how biological compatibility and local support affect therapeutic integration.
