Abstract

This study evaluates the viability of adipose aspirates harvested with the LipiVage system (Genesis Biosystems Inc, Lewisville, TX), a newly developed fat harvesting device, and determines a potentially preferred method for possible large-quantity fat graft harvesting. Adipose aspirates were harvested with the LipiVage system from the abdomen of 16 female patients (group 1, n = 8) according to the instruction by the manufacturer and with conventional liposuction (group 2, n = 8). Samples from conventional liposuction were spun at 50 g for 10 minutes and the resulting middle layer of fat was collected. All fat graft samples were evaluated with trypan blue vital staining for viable adipocyte count, glycerol-3-phosphatase dehydrogenase (G3PDH) assay for intracellular enzyme activity, and histology. In this study, group 1 had significantly higher viable adipocyte count than group 2 had (3.7 ± 0.64 versus 2.37 ± 0.56 × 10 /mL, P = 0.0021). G3PDH assay showed a marked increase of intracellular enzyme activity in group 1 compared with in group 2 (0.61 ± 0.10 versus 0.34 ± 0.13 U/mL, P = 0.00045). Histology revealed normal structures of fragmental fatty tissues in both groups. While adipose aspirates by both modalities maintain normal structure, the LipiVage system yields a greater number of viable adipocytes and sustains a higher level of intracellular enzyme activity within fat grafts and can potentially be a preferred method of choice for large-quantity fat graft harvesting.
