Autologous fat transplantation is used for soft tissue augmentation in reconstructing various tissue defects, primarily congenital or acquired facial anom-alies, facial rejuvenation, and cosmetic breast aug-mentation in plastic surgery [1-3]. Although aspirated fat tissue is a safe natural filler with a natural texture, softness, and contour, there are some associated problems, including unpredictability and a low rate of graft survival owing to partial necrosis. Magnetic resonance imaging studies have indicated that the resorption rate in clinical use is 55–70% of the injected volume [4]. Many clinical methods have been developed to enhance the viability and improve the survival of transplanted fat tissue [2, 3, 5-7].
