Quick answer

This is a hypothesis, not a proven mechanism. Researchers behind cell-assisted lipotransfer proposed that adipose-derived stromal cells may help new vessels grow into the graft. They might do this by turning into endothelial cells or by releasing growth factors. Some clinical studies report better volume retention with cell-enriched grafts. However, the studies vary widely in their methods, and the evidence on how vessels form in the graft is limited.

Answer

The original 2008 study had 40 patients and no control group [7]. A 2025 systematic review of 12 studies called for larger long-term randomized trials [8].
