Scanning electron microscopy images and fibril analysis in neocartilage. (A) Samples were fixed and imaged after 4 weeks culture. Scale bar = 1 μm. (B) Chondroitinase ABC (C-ABC), hydrostatic pressure (HP), and all combinatorial treatments significantly increased the fibril diameter. Fibril density was significantly increased over control in all treatments with the exception of hydrostatic pressure. Data reported as mean ± standard deviation. All groups not connected by a common lowercase letter are significantly different (P <0.05). TGF-β1, transforming growth factor beta-1.
