Fig. 8. Quantification of Arp2/3-complex and actin mRNA localization in fibroblasts treated with cytochalasin D or colchicine. Cytochalasin D (CD) and colchicine were used to disrupt actin filaments and microtubules in the fibroblasts, respectively. The proportion of the cells with localized mRNA was quantified by counting all the cells in randomly selected fields in the fluorescence microscope. 300-500 cells were counted for each type of mRNA from at least three independent experiments. Prefixes: ch, chicken; hm, human. Error bar indicates s.e.m. *, statistically significant (P<0.05) differences from control cells treated with no drug. **, statistically significant differences from control cells treated with no drug (P<0.01).
