Cellular migration, proliferation, and contraction. An in vitro approach to a clinical problem--proliferative...

Presently used animal models of proliferative vitreoretinopathy reflect only cell proliferation and contraction. We used an in vitro model that measured cell migration, proliferation, and contraction. The following four drugs were assayed on this system: daunomycin, taxol, colchicine, and cytochalasin B. Daunomycin was the most effective drug against cell proliferation and cell migration but had no effect on cell contraction; taxol and colchicine affected all three parameters. Cytochalasin B was the least effective drug tested.
