Effect of ONO-8815Ly on the expression of MMP-3 in femoral condyles. (a) Immunostaining for MMP-3 at two weeks after the operation. Sections of (a to e) medial and (f to j) lateral femoral condyles were prepared from samples of (a and f) G-S, (b and g) G-C, (c and h) G-0, (d and i) G-80, and (e and j) G-400. Magnification, 400×. Scale bar, 200 μm. Proportion of MMP-3-positive cells in (b) medial and (c) lateral femoral condyles at two weeks after the operation. Values are the mean ± standard deviation. *P < 0.05. MMP-3, matrix metalloproteinase-3; N.S, not significant.
