FIG. 8.

Cross-sections of harvested tissues in ectopic cartilage tissue formation after 8 weeks. A much less intense extracellular matrix (ECM) was stained for constructs in collagen type II sponge group (A) and Col II/FN group (B). Deep red color of ECM shown using Safranin O staining indicated intense glycosaminoglycan deposition around cells for constructs of Col II/rFN/Cad-11 and showed that new tissue contained islets of cartilage-like tissue (C).
