The graphs show the various intensities of centrosome immuno-staining with antibodies against gamma-tubulin on the same coverslip depending on the presence/absence of actin filaments (left) or on the amount of actin filaments (right). Data were pooled from 3 independent experiments. Left graph: without actin n=69, with actin n=26, right graph n=26. N.s. means no statistical difference between the data set according to Mann-Whitney test.
