Abstract:
BACKGROUND:Adipose tissue-derived stem cells are considered to be a promising source in the field of cell therapy and regenerative medicine. In addition to direct cell replacement using adipose tissue or purified stem cells, intercellular molecule exchange by the adipose tissue complex, a vast array of bioactive secretory factors, demonstrated beneficial effects by reducing tissue damage and stimulation of endogenous repair. However, for therapeutic purposes, the use of secretome derivatives, such as full conditioned media or purified exosomes generated in vitro, may present considerable disadvantages for cell manufacturing, storage, product safety, and their potential as a ready-to-go therapeutic product. METHODS:In this study, the effect of a liquid fraction of lipoaspirates isolated intraoperatively from 28 healthy donors was evaluated for their protective effect against oxidative stress and senescence, proliferation, and migration in vitro on normal human melanocytes, keratinocytes, and fibroblasts. Immunoenzymatic quantification of several growth factors and important signal molecules was used to define the biological profile of physiological adipose tissue secretome. RESULTS:Adipose tissue extracellular fraction (AT-Ex), isolated from lipoaspirate, exhibited significant potential for skin repair. AT-Ex augmented dermal and epidermal cell proliferation in a dose-dependent manner without promoting cancer cell growth. Moreover, migration of dermal fibroblasts, an important phenomenon implicated in endogenous repair, was enhanced by AT-Ex treatment. AT-Ex has a positive impact on oxidative stress damage when cells are exposed to extrinsic hostile factors and prevent a fibroblast senescence phenotype including paracrine functions associated with skin aging. CONCLUSIONS:Collectively, our findings propose natural systems carrying the physiological balance of in-vivo produced secretome that could improve cutaneous wound healing and tissue repair. This approach, representing an innovative perspective and therapeutic strategy in regenerative medicine, could also be combined with autologous stem cell grafts to treat chronic nonhealing wounds, stable vitiligo, severe burns, and post-oncological scarring.
