For the screening of compounds, we have optimized the page migration test compounds identified which inhibit EGF-induced EMT, HGF, IGF-1 or signaling. Suitable compounds were used as positive controls for each reference EGF, HGF and IGF-1 test EMT each weight Hlt HLT. The screen was strictly U con as an imaging test, in which the cores were colony scanned in each well and analyzed. Compounds that are cytotoxic or inhibiting the growth Vargatef BIBF1120 of cells that compounds: Prepared before treatment, and 24 h after induction of EMT-effect for the screening of compounds in this analysis were in three categories EMT divided can k, not the inhibition of cell growth , and compounds which inhibit not MPE or growth inhibitor. Examples shown in Figure 1D cell colonies labeled these three categories. The combination of these three compounds was determined by image analysis of disk images. The image analysis and the robustness of routine test has been developed for the test shown in Figure 2. For each image, so that the total number of cells in the colony, and the coefficients of the image segmentation routine one spread value were measured. The spreading factor is defined as the standard deviation of the positions of the cell colonies from the center of the colony. Followed by the combination of images in periods T1 and T2 in the ratio Ratio of the number of cells and measure to take measures Dispersionsverh ratio Ratio cells to the state of cell growth and migration of the dispersion state of the cells obtained correspond each cell colony.
The results of these two report parameters were used to determine the inhibitory properties of the test compounds EMT. We analyzed the consistency and robustness of the analysis. We validated that the CDR signal strong in the race, where intra-plate Z-constant factor 0.5. Gr This embroidered between positive and negative signals Identification of potential inhibitors of screening for compounds that target the EMT, we tested a collection of 267 compounds are specific inhibitors to identify if any of them can EGF, HGF and IGF-1-induced EMT inhibit Y-27632 this test. Pricing information for the screen-specific inhibitors EMT is listed in Table S1. Taken, because we were interested in compounds that inhibit any growth inhibition and cell dispersion k Nnte with a broad concentration range of more than 0.5 log differences. Therefore, the concentrations of the compounds in two EMT screen are tested.
