Abstract (original English)

Adipose-derived stem cells (ASCs) have been growing in popularity for their potential in wound healing and tissue engineering. Stem cell therapies are limited in application, with the need to maintain cell viability and function as well as safety concerns. It has been increasingly reported that the effects of ASCs are predominantly attributable to the paracrine effects of the secreted factors, which can be collected in conditioned medium (CM). The goal of this systematic review was to investigate the effects on wound healing of CM collected from ASC culture. Original articles relevant to ASC-CM and wound healing ( in vitro : dermal fibroblast, epidermal keratinocytes, and their equivalent cell lines; in vivo : full-thickness wound models) were included. The agreement level of selections between two investigators was calculated by the kappa scores. And the information concerning to the publications, CM preparation, and its application and effects was extracted and reported in a systematic way and summarized in tables. In total, 121 publications were initially identified through a search of the PubMed/MEDLINE database with a specific search algorithm, and 36 articles were ultimately included after 2 screenings. Nineteen were in vitro studies that met the search criteria and 17 were in vivo studies with or without in vitro data. In summary, based on the included articles, treatmen
