Fig 5. Periostin-mediated chemotaxis of monocytes.

Monocytes from healthy controls were seeded in the upper compartment, and medium containing 500 or 1000 ng/mL of recombinant periostin (rPn) was added to the lower compartment of a Transwell. Two hours post-incubation, cells were collected from both compartments and manually counted. The graph displays the ratio of migrating monocytes. The results represent four independent experiments. Data are shown as a mean ± standard error of the mean (SEM). Statistical analysis was performed using one-way analysis of variance followed by Dunn’s test. n = 4, *P < 0.05.
