Abstract

In tissue engineering technology, polymer-ceramics or polymer-polymer composites have been considered as advanced scaffolds having mechanical stability, biocompatibility, cell proliferation, and easy processability. However, the relationship between the mechanical properties and the cell proliferation behavior of such composite scaffolds has not been clarified yet. In this study, two types of composite scaffolds, poly(ethylene terephthalate) (PET) fiber/collagen and β-tricalcium phosphate (β-TCP)/gelatin scaffolds, were investigated. MC3T3-E1 cells were cultured in these scaffolds under appropriate conditions. Compression tests were then periodically conducted to evaluate the compressive elastic modulus. It was found that the modulus of the scaffolds containing cells increased with the cell culture period. It is noted that the modulus of the β-TCP/gelatin with cells was approximately seven times larger than that of the PET fiber/collagen with cells.
