Intermittent hypoxia enhanced RANTES-induced chemotaxis of monocytic THP-1 cells. Monocytic THP-1 cells were treated with normoxia or intermittent hypoxia as described, and RANTES-mediated chemotaxis were processed. a Photos represented for normoxia-treated or intermittent hypoxia-treated monocytic THP-1 cells that migrated toward lower chamber through the transwell filter. Chemotaxis cells were indicated by black arrow. Scale bar = 100 μm. b Statistical results from three experiments showed significantly enhance the chemotaxis toward RANTES. (Data are presented as mean ± SEM; *p < 0.05 vs. Normoxia)
