Abstract

- Compared to standard 2D culture systems, new methods for 3D cell culture of adipocytes could provide more physiologically accurate data and a deeper understanding of metabolic diseases such as diabetes. By resuspending living cells in a bioink of nanocellulose and hyaluronic acid, we were able to print 3D scaffolds with uniform cell distribution. After one week in culture, cell viability was 95%, and after two weeks the cells displayed a more mature phenotype with larger lipid droplets than standard 2D cultured cells. Unlike cells in 2D culture, the 3D bioprinted cells did not detach upon lipid accumulation. After two weeks, the gene expression of the adipogenic marker genes PPAR. and FABP4 was increased 2.0- and 2.2-fold, respectively, for cells in 3D bioprinted constructs compared with 2D cultured cells. Our 3D bioprinted culture system produces better adipogenic differentiation of mesenchymal stem cells and a more mature cell phenotype than conventional
