Impact of cannabinoids on motility related properties of single cells.

A) shows the mean speed and standard error of the mean (sem) of single LN229, U87 and U138 cells, when treated with cannabinoid receptor inverse agonists. B) and C) depict the directionality and contact area of the same cell lines and treatments together with the sem. For all parameters cell line specific changes that have no apparent receptor specificity can be observed. Statistics was performed using a Kruskal-Wallis test and significance was chosen for p<0.05. The asterisk denotes significant results regarding the respective measurement indicated with the bar.
