Stromal Vascular Fraction
يعرف أيضا باسم: الكسر الوعائي اللحمي المستخلص من الدهون, الجزء الوعائي اللحمي, الكسور الوعائية اللحمية, إس في إف, SVF
The stromal vascular fraction (SVF) is a heterogeneous mix of cells obtained from adipose tissue after removing mature fat cells; it contains stromal/stem cells, endothelial cells, pericytes and immune cells.
What is SVF (stromal vascular fraction)?
Stromal vascular fraction (SVF) is the heterogeneous mix of cells left after mature fat cells are removed from processed adipose tissue. It contains stromal/stem cells, endothelial cells, pericytes and immune cells. SVF is isolated from liposuctioned fat by enzymatic or mechanical processing and is used in research and in some fat grafting procedures. It is not a purified stem cell product, and its composition depends on the processing method.

نظرة عامة
SVF is produced from liposuctioned fat by enzymatic digestion or mechanical processing and then separated from adipocytes. It is not a purified stem cell product: stem/stromal cells are a minority of the cells. SVF is used in research and in some aesthetic and regenerative procedures, including cell-assisted fat grafting. The composition and clinical value of SVF depend on the processing method and the indication, and regulatory status varies by country. The ISSCR notes that enzymatic or ultrasonic processing of adipose tissue can alter the original function of the cells, so safety and efficacy must be shown for each specific use.
