Abstract (original English)

The goal of this study was to investigate the effect of resveratrol treatment on the osteogenic potential of human and rat adipose derived stem cells in a 3-D culture environment. Adipose derived stem cells (ADSCs) have been widely studied and have shown promise as a potential source of osteogenic progenitor cells. Previous work had investigated the effect of 25 μM resveratrol on the osteogenic differentiation of rat ADSCs in a 3-D environment and found that pre-treating cells for one passage prior to seeding on the scaffold yielded significantly more mineralization than untreated cells. We first sought to investigate whether this result was also observable with human ADSCs and found that the human cells did not respond to 25 μM resveratrol in a positive manner suggesting a species specific difference in resveratrol dosage. Therefore, we next investigated multiple doses at or below 25 μM resveratrol for both rat and human ADSCs. We found that doses below 25 μM caused significantly more mineralization than 0 (untreated) and 25 μM treated cells in a 3-D culture environment. Further, we observed species differences in the total amount of mineralized matrix, as well as the mean mineral density suggesting that the nature of mineralization of the extracellular matrix was different between species. Histological examination of the scaffolds showed that the human cell constructs remain
