Cell yield, viability, and proliferation. (A): Overall number of cells isolated from adipose tissue harvested via laser-assisted liposuction and suction-assisted liposuction. Laser-assisted liposuction resulted in a lower viable cell yield than suction-assisted liposuction (*, p < .05). Viable cells were identified by trypan blue exclusion. (B): Laser-assisted liposuction was also associated with a lower percentage of cell viability (*, p < .05). (C): Effect of the liposuction technique on the proliferation of adipose-derived stromal cells in vitro was determined by the XTT cell proliferation assay. There were significant differences in absorption values between the proliferation of cells obtained by laser-assisted liposuction and suction-assisted liposuction at 18, 24, 72, 96, 120, 144, and 168 hours (*, p < .05). Abbreviations: OD, optical density; SAL, suction-assisted liposuction.
