Abstract

Adipose-Derived Stem Cells (ADSCs) have multi-directional differentiation potential; however, their efficiency in differentiating into mature adipocytes remains low, which is a limitation for clinical and research applications of stem cell therapy. Curcumin has been reported to promote the proliferation of adipose-derived stem cells, but the effects of curcumin on the secretion of ADSC exosomes and the function of exosomes on adipogenic differentiation have not been assessed. Therefore, the objective of the present study was to investigate the exosome of ADSCs stimulated with curcumin and the consequence for adipogenic differentiation. Human ADSCs were isolated by the adherence method and characterized according to adipogenic, osteogenic, and chondrogenic differentiation ability. Exosomes were extracted from the supernatant of the third-generation ADSCs, and characterized by transmission electron microscopy and western blotting. Curcumin (10 μmol/L) was added to the complete culture medium 3 days before the extraction, and the influence of the exosomes on adipogenic differentiation was assessed. The human ADSCs showed mesenchymal stem cell characteristics and could differentiate into mature adipocytes, osteoblasts, and chondrocytes. Exosomes secreted by curcumin-treated ADSCs showed typical exosome characteristics and enhanced cell migration compared with that of exosomes in the untreated group. Moreover, curcumin-treated exosomes increased the number of fat cells produced after adipogenic differentiation but not the volume of fat cells. Overall, these results indicate a beneficial role of exosomes from ADSCs on adipogenesis and ADSC activity, providing new insight into the processes of fat accumulation and potential new strategies for improving the expansion of ADSCs for their clinical use in regenerative medicine.
