Movie of Pih1d3−− trachea cilia. Motility of trachea cilia in Pih1d3−− mice was examined by a high speed camera (HAS-500; Detect) with a halogen lamp via an upright microscope (AxioPlan2; Carl Zeiss). The images were captured at 100 frames/s during 2 s. Note that trachea cilia were motile in Pih1d3−− mice.
