Extended Data Fig. 10: The transfection efficiency of AAV2 virus in cartilage of mice.

The efficiency of AAV2 infection in articular chondrocytes was assessed by expressing enhanced green fluorescent protein (EGFP) using AAV2. After 6 weeks of DMM surgery in mice, the virus was injected into the joint cavity for 6 another 6 weeks. The expression of EGFP protein was detected using immunofluorescence. Scale bars, 200 μm.
