Abstract (original English)

Background Adipose-derived mesenchymal stem cells (ADSC) may have a potential dual role in soft tissue augmentation by suppressing inflammation and promoting regeneration. Due to these properties, there is increasing interest in their potential use in autologous fat grafting, particularly to the breast. Objectives The authors isolate and compare ADSC derived from abdominal and breast tissues with a hypothesis that different adipose tissue sources may demonstrate different functional characteristics affecting outcomes in autologous cell transplantation in reconstructive and aesthetic surgery. Methods Adipose-derived mesenchymal stem cells from abdominal and breast tissues were isolated and compared in terms of surface marker expression, differentiation capabilities, and both fibroblast growth factor (FGF) and receptor expression. Immunophenotype of macrophages was also investigated using cell surface markers following a 7-day co-culture period with ADSC. Results Results showed similar cell surface phenotype and multilineage differentiation capabilities of ADSC derived from abdominal and breast tissues. Variations of FGF expression were demonstrated on reverse transcription polymerase chain reaction, with a significantly higher expression of FGF2 seen in breast ADSC. Following the 7-day co-culture period, increased expression of the anti-inflammatory surface marker CD206 was iden
