# Is autologous fat the same as SVF or stem cells?

## Short answer

No. Autologous fat is the whole tissue: mature fat cells, blood-vessel cells, fibroblasts, preadipocytes, stromal cells and the structural matrix. The stromal vascular fraction (SVF) is a cell mixture separated from that fat, usually by enzymatic digestion, and adipose-derived stem cells are only a small part of it. Regulators generally treat whole fat and isolated SVF differently. Enzymatic isolation of SVF is considered more than minimal manipulation.
