摘要

Background: Adipose tissue-derived stromal cells augment wound healing and skin regeneration. It is unknown whether and how they can also influence dermal scarring. The authors hypothesized that adipose tissue-derived stromal cells inhibit adverse differentiation of dermal fibroblasts induced by the pivotal factor in scarring, namely, transforming growth factor (TGF)-(3. Methods: TGF-(3l-treated adult human dermal fibroblasts and keloid scar-derived fibroblasts were incubated with adipose tissue-derived stromal cell-conditioned medium and assessed for proliferation and differentiation, particularly the production of collagen, expression of SM22a, and development of hypertrophy and contractility.
