Development of Biodisc Tissue-Engineered Using Annulus Fibrosus and Nucleus Pulposus Cell on PLGA/DBP Scaffold |
초록 |
We fabricated poly(lactide-co-glycolide)(PLGA) scaffolds impregnated demieneralized bone particle(DBP)(PLGA/DBP)content to investigate the effect of cell viability and proliferation of intervertebral disc(IVD) cells. Annulus fibrosus(AF) and nucleus pulposus(NP) cells were seeded in PLGA and PLGA/DBP scaffold to evaluate mRNA expression and a proliferation of AF and NP cells according to content of DBP. Reverse transcription polymerase chain reaction(RT-PCR) was assessed to measure of mRNA expression. Scaffolds were implanted in subcutaneous of athymic nude mouse for histology in vivo. The formation of disc-like tissue appeared in PLGA/DBP scaffold than control. Especially, 40 and 80 wt% of DBP positively affected to proliferation and maintenance of phenotype in scaffold. These information would contribute to design of PLGA/DBP scaffold for tissue engineered IVD regeneration. Acknowlegement: This research was supported by KMOHW (0405-BO01-0204-0006) and SCRC (SC3100). |
