Objective To explore the possibility of constructing tissue engineered cartilage complex three-dimensional nano-scaffold with collagen type II and hyaluronic acid (HA) by electrospinning. Methods The three-dimensional porous nano-scaffolds were prepared by electrospinning techniques with collagen type II and HA (8 ∶ 1, W ∶ W), which was dissolved in mixed solvent of 3-trifluoroethanol and water (1 ∶ 1, V ∶ V). The morphology were observed by light microscope and scanning electron microscope (SEM). And the porosity, water absorption rate, contact angle, and degradation rate were detected. Chondrocytes were harvested from 1-week-old Japanese white rabbit, which was disgested by 0.25% trypsin 30 minutes and 1% collagenase overlight. The passage 2 chondrocytes were seeded on the nano-scaffold. The cell adhesion and proliferation were evaluated by cell counting kit 8 (CCK-8). The cell-scaffold composites were cultured for 2 weeks in vitro, and the biological morphology and extracelluar matrix (ECM) secretion were observed by histological analysis. Results The optimal electrospinning condition of nano-scaffold was 10% electrospinning solution concentration, 10 cm receiver distance, 5 mL/ h spinning injection speed. The scaffold had uniform diameter and good porosity through the light microscope and SEM. The diameter was 300-600 nm, and the porosity was 89.5% ± 25.0%. The contact angle was (35.6 ± 3.4)°, and the water absorption was 1 120% ± 34% at 24 hours, which indicated excellent hydrophilicity. The degradation rate was 42.24% ± 1.51% at 48 days. CCK-8 results showed that the adhesive rate of cells with scaffold was 169.14% ± 11.26% at 12 hours, and the cell survival rate was 126.03% ± 4.54% at 7 days. The histological and immunohistochemical staining results showed that the chondrocytes could grow well on the scaffold and secreted ECM. And the similar cartilage lacuma structure could be found at 2 weeks after co-culture, which suggested that hyaline cartilage formed. Conclusion The collage type II and HA complex three-dimensional nano-scaffold has good physicochemical properties and excellent biocompatibility, so it can be used as a tissue engineered cartilage scaffold.
