Fig. 12.

Hybrid scaffold of collagen PLGA mesh/collagen web. A Initial microstructure of PLGA mesh/collagen web, B, C microstructure of PLGA mesh/collagen web after 1 and 4 weeks of chondrocyte incorporation. Chondrocyte was attached and suspended on the collagen web. P and C indicate PLGA mesh and collagen web, respectively. D Northern blot analyses of chondrocytes seeded in PLGA mesh/collagen web scaffolds for the gene encoding ColI, COLII, and ACAN for the period of 0, 2, 4, 12 weeks.
