Figure 2.In vitro characterization of chondrocyte sheets (n=3). (A–C) Chondrocytes transfected for 24 hours in different groups (magnification x40). (D–F) The chondrocyte sheets formed after 8 weeks could be detached easily and completely. (G–I) SEM detection of chondrocyte sheets in different groups (magnification x1000; bar 50 μm).
