Abstract (original English)
To deliver efficiently osteogenic, chondrogenic or adipogenic induction genes, such as Runx2, SOX9 and C/EBP-α, to adipose tissue-derived stem cells (ADSCs), a photo-mediated nanocomplex internalization gene delivery system was designed using chlorin e6 as a photosensitizer (PS) and polyethyleneimine (PEI) as a gene delivery carrier. In this system, gene delivery efficacy was significantly increased in ADSCs by photo irradiation. The gene transfection efficiency of Runx2, SOX9 and C/EBP-α was increased by 8.6-, 6.7- and 9.3-fold, respectively, by applying 0.7J/cm(2) of irradiation. Osteogenic, chondrogenic and adipogenic differentiation was confirmed by differentiation-related markers and histological analysis. ADSCs transfected with Runx2, SOX9 and C/EBP-α genes via photo irradiation indicated enhanced differentiation in comparison to the non-irradiated cells. These findings demonstrate that photo-mediated internalization is a promising system for efficient gene delivery and differentiation in ADSCs.
