Figure 5. Decreased apoptosis in the IA arteries of rADAMTS-5-administered mice. (A) Representative images of TUNEL staining indicating less apoptosis (displayed in red) in arteries from rADAMTS-5-administered mice than in those from control (CTRL) mice. (B) Quantification of the TUNEL (+) cells in arteries from the control (CTRL) mice and rADAMTS-5-administered mice. **P<0.01.
