| Outline of Final Research Achievements |
In this study, PLLA porous hollow fiber scaffold was developed by using electrospinning to maintain nutrient supply in cultured cartilage. Porous hollow fiber scaffold was fabricated by using the co-axial spinneret. PLLA/PEO solution as the outer solution was prepared by dissolving poly-L-lactic acid (PLLA) and polyethylene oxide (PEO) in 1,3-dioxolane. 40% ethanol was used as the inner solution. According to SEM observation, the fabricated fiber had porous hollow structure. According to fluorescent observation of diffusion of fluorescent solution through the fiber, the developed PLLA porous hollow fiber scaffold had an interconnected structure to maintain supply of a culture medium in cultured cartilage.
