| Outline of Final Research Achievements |
The spinning device was developed to fabricate chondrocytes-enclosing fiber scaffolds. The fiber scaffolds were fabricated by collecting chondrocytes-enclosing sodium alginate fiber in the CaCl2 solution using the winding drum. Chondrocytes were distributed uniformly in the fiber, and the fiber pitch and cell pitch were controlled by changing the winding speed and traverse speed. Collagen was locally existed around cells in the fiber scaffold for low cell density, whereas collagen was existed along the fiber in the fiber scaffold for high cell density. When sodium alginate was removed from the fiber scaffold by EDTA treatment, the fiber structure was maintained by synthesized extracellular matrix in the case of 33.7±15.1 μm of cell pitch.
