Vessel enlargement induced by anti–VE-PTP antibodies requires Tie-2. (A) Allantois explants from E8.5 Tie-2 +/+, Tie-2 +/−, or Tie-2 −/− embryos (as indicated) were cultured on gelatin-coated ultrathin glass slides in the presence of polyclonal antibodies against VE-PTP for 22 h. (B) Allantois explants from E8.5 embryos were cultured in medium (untreated) or in the presence of 600 ng/ml Ang1. Subsequently, endothelium was visualized in all samples in A and B by indirect immunofluorescence staining for VE-cadherin. Bars, 50 µm.
