In vitro biocompatibility assessment of a novel PRGD/PDLLA/NGF composite material
2011
The objective of this study was to evaluate the degradability and biocompatibility of a novel composite materials which was grafted with RGD and immobilized with NGF(PRGD/PDLLA/NGF). The releasing of NGF, the biodegradability and cell-biocompatibility of PRGD/PDLLA/NGF membrane were evaluated in vitro. The experimental results showed that the NGF release process was prolonged over 30 days. Furthermore, the PRGD/PDLLA/NGF showed a better hydrophilicity, better biodegradation properties and cells affinity than PDLLA, which means a good support to adhesion and proliferate of Schwann cells. Therefore, the novel composite material holds considerable promise as scaffolds in nerve tissue engineering.
