A computer-assisted comparison of the motile behavior of regA⁻ and Ax4 cells perfused with buffer in the absence of chemoattractant

Cell type	Cell no.	Instantaneous velocity (μm/min)	Directional change (degree/min)	Maximum length (μm)	Maximum width (μm)	Roundness (%)
Ax4	10	10.8  ± 3.9	44.3  ± 7.9	21.2  ± 4.1	10.4  ± 1.8	50.3  ± 13.2
regA	9	11.1  ± 4.2	51.0  ± 6.3	22.3  ± 3.5	10.9  ± 1.3	46.8  ± 15.2

The behavior of each cell was analyzed for 10 min. Images were digitized at 15-s intervals. Values are given as mean ± SD. The five measured parameters proved statistically indistinguishable between the two cell types using the Student's t test. All p values were above 0.05.
