ELISA data showing levels of G-CSF in serum and bone marrow in control and mouse model of periodontitis. A significantly greater level of G-CSF in serum from the periodontitis group, compared with the control group (A). The amount of G-CSF in bone marrow tended to be upregulated in the periodontitis group, but there was no difference between the two groups (B). Data are presented as mean ± SD. *P < 0.05 using two-tailed Students t-test. ns, no differences
