Autologous fat transfer, or lipofilling, is a common technique used for soft tissue reconstruction. It has been used for many years, but the technique is associated with a significant graft resorption rate (20% to 80%). To improve the fat graft survival rate, several methods have been tested, and one has appeared more promising: cell-assisted lipotransfer (CAL). In the CAL method, fat is enriched with adipose-derived stromal cells (ASC), contained in the stromal vascular fraction (SVF) obtained after enzymatic digestion of fat or after cell culture to improve the fat survival rate...
