Adipocyte and preadipocyte viability in autologous fat grafts: comparing the water jet-assisted liposuction (WAL) and Coleman techniques

Background Autologous fat transplantation is a promising technique for soft tissue augmentation. However, the long-term maintenance of fat grafts remains unpredictable. Based on Peer’s cell theory, techniques that cause less cellular damage will optimize graft integration. Water jet-assisted liposuction (WAL) was introduced as a gentle and efficient technique for harvesting a large volume of fat in a short period of time. In this study, we evaluated the viability and function of adipocytes and preadipocytes harvested using WAL and compared this with the Coleman technique.
