 | | The effect of the cyclic integrin antagonist on RPE cell attachment onto different extracellular matrices (laminin, collagen IV, fibronectin), RPE cell invasion stimulated by PDGF-BB or serum, and migration stimulated by PDGF-BB, vascular endothelial growth factor (VEGF) or serum was explored. |
 | | The cyclic integrin antagonist was added directly to the upper part of the chamber (0.001 ng/ml, 0.01 ng/ml, 0.1 ng/ml, 1 ng/ml, 3 ng/ml, or 10 ng/ml). |
 | | Furthermore, a lack of toxicity for the integrin antagonist and the control peptide in the concentration range tested (0.01 μg/ml, 0.1 μg/ml, 1 μg/ml, 30 μg/ml and 300 μg/ml) was determined by use of the trypan blue exclusion assay (data not shown). |
