Primary and passaged costal chondrocytes in scaffoldless TMJ disc engineering. (top) Primary CC (P0) constructs stained uniformly for collagen, GAG, and cells. TMJ disc cell (TMJ) constructs did not stain for GAG, but stained uniformly for collagen and cells. Passaged CCs (P1, P3, P5) formed fluid-filled spheres, with only an outer ring staining for cells and ECM. (bottom) All constructs stained positive for type I collagen. Only CC constructs stained positive for type II collagen, the most intense staining around the outside of constructs and within fluid-filled centers. Controls: f- knee meniscus tissue and l- articular cartilage tissue. http://www.springerlink.com/content/gv8266l31307t815/.
