Abstract

In this work, poly L-lactide (PLLA) membranes with different morphologies were prepared and the equilibrium phase diagram of membrane formation system of ethanol, methylene chloride, and PLLA was studied. Based on the phase diagram, particulate and porous membranes, dominated by crystallization and liquid-liquid demixing, respectively, could be prepared by changing the PLLA concentration of casting solution. In addition, in vitro interaction of MG-63 osteosarcoma cells and PLLA membranes with dense, porous and particulate morphologies was investigated. It was found that the particulate membrane not only could improve cell adhesion and growth, but also could upregulate the osteoblastic phenotype. Therefore, the PLLA membrane with particulate morphology satisfies the biomaterial requirement necessary for temporary scaffold to transplanted osteoblasts and provides a means for the architectural design of more complex tissue-engineered systems.
