Abstract (original English)
Background Although water-jet force-assisted liposuction technique (WAL) was demonstrated to have favorable effects on fat grafting, controversy continues concerning the application of centrifugation for lipoaspirate harvested via WAL. As a controversial technique, plastic surgeons often get perplexed to the necessity of using centrifugation during fat grafting procedure. In the present study, we adopted the recommended centrifugal intensity (1200g, 3 minutes) to process lipoaspirate and focused on the influence of centrifugation on the fate of lipoaspirate harvested with WAL technique. Methods Lipoaspirate was obtained from 10 healthy Chinese female patients who underwent cosmetic liposuction. The harvested lipoaspirate was either not centrifuged (group A) or centrifuged at 1200g for 3 minutes (group B). Lipoaspirate from each group was compared in the in vitro and in vivo experiments. The influence of centrifugation on lipoaspirate viability and lipoaspirate survival after grafting were evaluated. Results The viability of the lipoaspirates was similar between equally volumetric uncentrifugal and centrifugal lipoaspirate. However, centrifugation at 1200g for 3 minutes concentrated stromal vascular fraction cells and adipose-derived stem cells in lipoaspirate; greater angiogenesis and weight retention rates were observed in centrifugal lipoaspirate after grafting than those unc
