Abstract
ABSTRACTIn this study, two types of scaffolds were fabricated by 3D printing. Morphology, physical properties, biochemical were evaluated. Cell morphology and distribution were observed. It was found that the silk fibroin/collagen (SF/C) scaffold-based material had significantly higher values than the silk fibroin/chitosan (SF/CS) scaffold-based material. Hematoxylin and eosin staining of the scaffolds revealed that the number of cells in the SF/C scaffold was higher. Cells grew well inside the SF/C scaffold as measured by scanning electron microscope. Reverse Transcriotion-Polymerase Chain Reaction (RT-PCR) and Western blot showed that type II collagen and Sox9 can be found in SF/C scaffold. Therefore, the SF/C scaffold exhibited better overall performance compared with the SF/CS scaffold.
