FIG. 9.

Potential therapeutic applications of culture-expanded and redifferentiated chondrocytes from osteoarthritic cartilage. From an osteoarthritic knee, cells are isolated (A), expanded (B), and then redifferentiated (C). The redifferentiated cells could be used to create a construct (D) for resurfacing the knee joint. The expanded or redifferentiated cells could be injected (E, F) or implanted in a scaffold (G, H) for focal defect repair. Color images available online at www.liebertonline.com/ten.
