ABSTRACT
Objective To investigate the composite of chitosan(CS) and polyvinyl alcohol (PVA) as scaffold carrier for rabbit chondrocytes nurture and growth.Methods The third passage of chondrocytes were seeded in CS/PVA gel scaffold and 24,48 and 72 h after which cytoactive and toxicity were determined by MTT respectively.After one,two and three weeks,the growing status and morphology of chondrocytes in CS/PVA gel were observed with scaning electron microscope (SEM) and laser confocal scanning fluorescence microscope (LCSM).Results The third passage of chondrocytes in CS/PVA gel scaffold remained high proliferation ability.MTT measuring cell activity and virulence,the result showed that the number of cells obviously increased with the time,with statistical significance of difference between each groups (P<0.05),without side effect to cells by the material.Observation of scaning electron microscope and confocal laser scanning fluorescence microscope showed that chondrocytes grew well with the scaffold of CS/PVA gel.Conclusion CS/PVA mixed gel material can be used as scaffold for rabbit chondrocytes growing for repairing cartilages defect in tissue engineering.
