Fig. 7. Ang2-mediated chemotaxis is PI 3-kinase-dependent. (A) IBE cells were preincubated with either 0.1% DMSO (vehicle) or 50 µM LY294002 for 30 minutes and assayed for chemotaxis as described for Fig. 2B. (B) FesKE5-8 cells and FesWT6-8 cells were examined for chemotaxis towards 1 µg/ml Ang2. Data are expressed as means±s.d. for quadruplicated wells. Representative data were obtained from two independent experiments.
