Abstract (original English)

Background Adipose tissue, which can be readily harvested via a number of liposuction techniques, offers an easily accessible and abundant source of adipose-derived stem cells (ASCs). Consequently, ASCs have become an increasingly popular reconstructive option and a novel means of aesthetic soft tissue augmentation. Objectives This paper examines recent advances in the aesthetic surgery field, extending beyond traditional review formats to incorporate a comprehensive analysis of current clinical trials, adoption status, and the commercialization pathway. Methods Keyword searches were carried out on clinical trial databases to search for trials using ASCs for aesthetic indications. An intellectual property landscape was created using commercial software (Thomson Reuters Thomson Innovation, New York, NY). Analysis of who is claiming what in respect of ASC use in aesthetic surgery for commercial purposes was analyzed by reviewing the patent landscape in relation to these techniques. Key international regulatory guidelines were also summarized. Results Completed clinical trials lacked robust controls, employed small sample sizes, and lacked long-term follow-up data. Ongoing clinical trials still do not address such issues. In recent years, claims to intellectual property ownership have increased in the "aesthetic stem cell" domain, reflecting commercial interest in the area. Howeve
