In 2001, researchers at UCLA described the isolation of a population of adult stem cells, termed Adipose-derived Stem Cells or ASCs, from adipose tissue. This article outlines the isolation of ASCs from lipoaspirates using a manual, enzymatic digestion protocol using collagenase.

The purpose of the study is to illustrate the technical procedure of stromal vascular fraction (SVF)-enriched fat grafting as a novel treatment of symptomatic end-neuromata. This technique provides advantages of both the mechanical barrier and the biological action at the cellular level by the processed and concentrated SVF.

We describe the isolation of cardiac extracellular matrix from C57Bl/6J control mice, tight-skin mice, and tight-skin mice treated with the IRF5 inhibitory peptide. We also describe the vasodilation studies on the isolated vessels from C57Bl/6J, tight-skin mice and tight-skin mice treated with the IRF5 inhibitory peptide.

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...

Neutrophils are among the first cells to arrive on the site of inflammatory immune response, and their functions and mechanisms have been studied extensively in vitro. We demonstrate a standard density gradient separation method to isolate human neutrophils from whole blood using commercially available separation media.
FAQs
An SVF preparation can contain stromal cells, endothelial cells, pericytes, immune cells, and blood-derived components rather than a single uniform cell type. That diversity allows investigators to examine tissue repair, inflammation, and angiogenesis within one fraction, but it also means biological effects and experimental results may reflect changing proportions of several populations.
Tissue disruption makes the adipose sample accessible to downstream separation, while controlled digestion helps release cells from the tissue structure. Filtration and centrifugation then support separation and concentration of the remaining vascular-associated fraction. Because each stage affects what is recovered, process control is important for preserving a usable and representative cell population.
The source of adipose tissue, digestion and other processing conditions, and subsequent handling can alter cellular composition and viability. These variables may change the relative representation of stromal, endothelial, pericyte, immune, and blood-derived populations. Consequently, samples prepared under different conditions may not produce directly comparable experimental or clinical outcomes, even when the overall workflow appears similar.
A typical workflow begins with adipose tissue disruption, followed by controlled digestion. The processed material is filtered, and centrifugation supports separation and concentration of the stromal vascular fraction while mature adipocytes are removed. The resulting population is then handled for the intended study. Consistent control of these steps helps maintain cell viability and reproducible composition.
The method is useful when a study needs a mixed adipose-derived cell population to investigate tissue repair, inflammation, or angiogenesis. In regenerative medicine, the fraction can support research on cell-based therapies. Its heterogeneous nature also allows researchers to examine these processes in the context of stromal, vascular-associated, immune, and blood-derived cellular components.
Differences in cell viability or composition should be considered alongside the biological outcome, because isolation conditions can influence both. A result attributed to the fraction may partly reflect variation in tissue source, processing, or handling. Standardized procedures therefore improve comparison across experiments and help clarify whether changes in repair, inflammation, or angiogenesis are biologically meaningful.
