rAprA does not reduce pipkinA^- cell motility. pipkinA^- cells were placed in wells in HL5 and were allowed to adhere for 30 minutes. rAprA was then added to 300 ng/ml, and cells were imaged starting 1 minute after adding rAprA. Elapsed time in minutes:seconds is at upper left. The horizontal field of view is 107 μm. Video is representative of 4 independent experiments.
