Figure 8: Specific tyrosine kinase inhibitors of syk and src do not reduce motility or colony formation by the metastatic 143B cells (panel (a) & (b)) or colony formation by the non-tumorigenic/non-metastatic TE85 cells (panel (c)). Motility and colony formation assays were performed in the presence of tyrosine kinase inhibitors or 1% DMSO as a vehicle control. Bars represent the means ± standard error of the mean of three individual experiments (scrape motility assays with four to six scrapes per group; colony formation assays with three wells per group). Double asterisks denote compared with the vehicle control groups; single asterisk (panel (b)) denotes .
