Toe joints skeletal tissue in CAIA and CAIA + SRL mice. Sections were prepared from toe joints of mice on days 7 and 14 after LPS injection. The sections were stained with toluidine blue (TB) pH 7.0 (a). Histological scores for skeletal tissue damage was graded as described for Fig. 2b. Values are the means ± SD (n = 6). *P < 0.05 versus CAIA. Arrows tissue damage; asterisks joint space; bar 200 μm
