Researchers at MD Anderson were trying to decide what method was the best to use to get the best fat to re-implant. Success of a fat graft depends on adypose derived stem cells and the stromal vascular faction.
They found that direct excision of fat from the abdomen or using Coleman’s technique with a centrifugation yielded the most ASC and SUF cells. Also the abdomen was a better site to harvest from than the flanks or axillae. I am still not sold totally on centrifugation.
