Recently, cell-based therapies, regenerative medicine, and tissue engineering have been progressing rapidly. With the injection of single cell suspensions, the injected cells are expected to remain around the damaged host tissues for the maintenance and recovery of native functions. Polylactide (PLA) has been shown to be important serving as tissue engineering scaffolds and drug delivery carriers because of its good mechanical properties, non-toxicity, processibility, and biodegradability. In this study, three types of PLA scaffolds were prepared and mouse-cell was implanted on PLA scaffolds. The structure of PLA scaffold was characterized by SEM, image analyzer and porosimeter. The cytotoxicity and biocompatibility of the scaffold was measured by WST-1 and microscopes. The result showed the correlation of ability of cell culture and morphology of PLA scaffolds. |
