Organism Tetrahymena thermophila

Method "Tetrahymena were analyzed with high-speed video microscopy to directly examine the behavior of cilia in motion. Digital recordings of cilia on the aboral surfaces of free-swimming wild-type and mutant cells were obtained at 500 frames per second. In these assays, the cilia of wild type were observed to beat in a highly coordinated manner, with obvious and defined metachronal waves."
Comments "Mutant cilia generated an average beat of 16.1±4.6 Hz, whereas wild-type cilia generated a beat of 15.9±3.7 Hz (n=15 for each trial)."
