Figure 2From: Matrix metalloproteinase-8 deficiency increases joint inflammation and bone erosion in the K/BxN serum-transfer arthritis modelIncreased joint inflammation and bone erosion in mice lacking Mmp8. Histologic scores of synovial inflammation (SI), cartilage damage (CD), bone erosion (BE) and tartrate-resistant acid phosphatase (TRAP) staining of ankle sections of Mmp8+ mice (n = 8) and Mmp8-/- mice (n = 7) at day 9 after intraperitoneal arthritis induction. Values expressed as mean ± standard error of the mean; *P < 0.05 by two-sided Mann-Whitney U test.Back to article page
