Abstract
In this study, porcine small intestinal submucosa (SIS) without immune response were used to make SIS/PLGA scaffolds with different SIS content i.e. 0, 10, 20, 40, and 80 wt%. Further, the attachment and proliferation of costal cartilage cells (CCs) in SIS/PLGA scaffolds were characterized. Glycosaminoglycan (sGAG) and collagen contents assay were conducted to verify the effects of SIS on extracellular matrix (ECM) formulation. The CCs specific gene expression was confirmed by polymerase chain reaction (PCR). In conclusion, the sGAG production was formed to be higher in the 20 wt% SIS/PLGA scaffolds, which showed enhanced CCs cell growth and proliferation compared with other scaffolds.
