title: Therapeutic applications of human adipose-derived stromal cells for soft tissue reconstruction.
abstract: Adipose derived stromal cells (ASCs) are a multipotent cell population derived from the stromal vascular fraction of lipoaspirate. Given their relatively broad differentiation potential and paracrine capabilities, ASCs represent a readily accessible, endogenous resource for novel reconstructive strategies. In particular, augmentation of autologous fat grafts with ASCs has already been employed clinically for restoration of soft tissue defects. While fat grafting alone remains highly unpredictable, enrichment of fat with supplemental ASCs, also known as cell-assisted lipotransfer (CAL), has been shown to significantly enhance volume retention. How addition of these cells to fat grafts results in improved outcomes, however, remains poorly understood. Furthermore, the safety of CAL in the setting of prior malignancy and post-radiation wound beds has yet to be fully determined, an important consideration for its use in cancer reconstruction. Thus, further studies to determine the how and why behind the efficacy of CAL are necessary before it can be widely adopted as a safe and reliable surgical technique.
