Cellular proliferation as determined by DNA content for cilia (+) and cilia (−) cells. Cells were incubated stationary or rotated at 1 Hz to stimulate cilia bending for 0, 12, 24, or 48 h. DNA content was determined and is presented as amount in rotated cells compared with amount in stationary cells at each time point. *P < 0.05 between cilia (+) and cilia (−); n = 3 (0 h) and n = 4 (12, 24, and 48 h).
