# SVF vs ADSC: how the stromal vascular fraction differs from adipose-derived stem cells

SVF and ADSC are often used interchangeably in marketing but are different products: SVF is a fresh, mixed cell fraction from fat; ADSC are the mesenchymal stem/stromal cells within it, usually expanded in culture and regulated as manufactured biologics.

## Quick answer

SVF is the whole cell mixture isolated from fat in one procedure without culture. ADSC (adipose-derived stem cells) are the multipotent stromal cells inside SVF, typically purified by culturing them for days to weeks. SVF is faster and heterogeneous; ADSC products are more uniform but are regulated as manufactured biologics in most jurisdictions.[1][2]

## Comparison

| Aspect | SVF | ADSC |
| --- | --- | --- |
| Preparation | Single session, no culture | Culture expansion (days–weeks) |
| Composition | Mixed: stromal, endothelial, immune, pericytes | Mostly mesenchymal stem/stromal cells |
| Cell dose | Limited by harvested fat | Can be scaled by expansion |
| Regulation | Depends on processing (minimal manipulation rules) | Usually regulated as a biologic/ATMP |
| Typical use | Cell-assisted fat grafting, research | Clinical trials, approved products in some countries |

## Why the distinction matters

Clinics may describe an SVF procedure as "stem cell" treatment. Because stem/stromal cells are only a fraction of SVF, the number of actual stem cells delivered is far lower than in a cultured product, and the two should not be assumed to have the same effects or risks.[1] The ISSCR advises that claims be specific to the product actually used.[3]
