Figure 4. Optimization of concentration of inhibitor of TGF-β receptor I (Ti). The growth and migratory regulation through Ti dose-dependent (25-100nM) assay of (A) Cellular proliferation and (B) Transwell cell migration and its relative quantification revealed degenerative characteristics when compared to control; whereas, the PDB showed a stimulatory effect. The representative results of 3 experiments demonstrated mean ± SD.
