Figure 4. Intermittent hypoxia increased MCP-1-induced chemotaxis of monocytes.

Figure 4

THP-1 cells were pretreated with normoxia or intermittent hypoxia as described in methods and then processed for the MCP-1-mediated chemotaxis assay. (A) Representative photos for normoxia- and intermittent hypoxia-treated THP-1 cells that migrated toward lower chamber indicated by black arrow. (B) Statistical results from three independent experiments were shown. Data were means and standard errors. (mean ± SE, *: P<0.05 vs. Normoxia).
