"Two types of analysis were used to quantitatively describe
the directional component inherent in cell velocity. The first
type of analysis plots the trajectory of each cell, beginning at
the origin and oriented such that the first step taken by each
cell is along the x-axis...The second type of analysis, plotting the cos
(?) of vectors tangential to the cell trajectory versus path length
traveled between each pair of vectors, revealed turning magnitudes in highly persistent cells that were not obvious in the trajectory analysis." |
| Comments |
"Keratocytes of the two eurythermal species, G. mirabilis and C. salinus, were capable of crawling the fastest, with maximal instantaneous rates of ˜40–45 µm·Min^–1. It is possible that there is some limit to keratocyte motility indicated by this maximal speed that might be reflected in an underlying cellular process governing motility rates." These are maximal instantaneous rates. Corresponds to 0.67 to 0.75µm/sec |
