Polysaccharides meet several criteria for a suitable biomaterial for tissue engineering, which include biocompatibility and ability to support the delivery and growth of cells. Nevertheless, most of these polysaccharides, for example dextran, alginate, and glycosaminoglycans, are highly soluble in aqueous solutions. Hyaluronic acid hydrophobized by palmitic acid and processed to the form of wet-spun fibers and the warp-knitted textile scaffold is water non-soluble, but biodegradable material, which could be used for the tissue engineering purpose. However, its surface quality does not allow cell attachment. To enhance the biocompatibility the surface of palmitoyl-hyaluronan was roughened by freeze drying and treated by different cell adhesive proteins (fibronectin, fibrinogen, laminin, methacrylated gelatin and collagen IV). Except for collagen IV, these proteins covered the fibers uniformly for an extended period of time and supported the adhesion and cultivation of dermal fibroblasts and mesenchymal stem cells. Interestingly, adipose stem cells cultivated on the fibronectin-modified scaffold secreted increasing amount of HGF, SDF-1, and VEGF, three key growth factors involved in cardiac regeneration. These results suggested that palmitoyl-hyaluronan scaffold may be a promising material for various applications in tissue regeneration, including cardiac tissue repair.
