Fig. 7: Effects of viral gene transfer on cartilage quality.

a Photomicrograph from 5-μm sections of cartilage from radial and 3rd carpal bone stained with SOFG. The left panel represents cartilage from joints treated with different doses of viral vectors and the right panel shows a representative section from the control joints. b SOFG stain uptake scores in radial and 3rd carpal joints. The top two doses tested showed higher stain uptake compared to the lower doses.
