Summaries of mitochondrial dynamics in intact or treated Hela and MEF cells.

Fu-Fi: Fusion followed by fission; Fi-Fu: Fission followed by fusion; Fu-Fu: Fusion followed by fusion; Fi-Fi: Fission followed by fission; Pd: Paired; UPd: Unpaired. The values in parentheses () are denoted as the absolute number of fission or fusion events for all the cells analyzed, while those in brackets {} are referred to the number of individual mitochondria observed. ζ: Data were presented as the mean ± standard errors of values obtained from 14–65 mitochondria and 26–231 events totally. †: Data were presented as the mean ± standard errors of values obtained from triplicate simulations at the same set of given parameters.
