Abstract (original English)
Background Nodules or calcifications have been a common complication after breast augmentation with fat grafting, especially in cases with partial bolus fat grafting. There are some clinical preventive measures, but mechanisms related to this complication have not been elucidated yet. Inorganic phosphate (PI), being a product of fat metabolism, is a well-known stimulus of other kinds of pathological calcification such as vascular calcification. We aimed to determine whether PI had a similar effect on formation of nodules after fat grafting. Methods Nodules or calcification after fat grafting models using nude mice were created by bolus fat injection. Levels of PI of necrotic liquid located in the central zone and mineralization deposition of graft were examined 1 week, 2 weeks, 1 month, 2 months and 7 months after bolus fat injection. External high phosphate solution was injected 3 times a week to the fat grafts for 2 months, and mineral deposition was examined. In addition, adipose-derived stem cells (ADSCs) were treated with high phosphate osteogenic differentiation medium in various concentrations and times. ADSCs were also treated with osteogenic differentiation in addition to tetramisole which could reduce the level of PI. Mineral depositions of the cells were examined. The central necrotic liquid was extracted from patients who found palpable nodules after breast augmenta
