摘要

Less than ten years has passed since the protein angiopoietin-1 (Ang-1) was identified as a ligand for Tie-2, a tyrosine kinase receptor found principally on vascular endothelial cells (8). Ang-1 and its receptor, in concert with VEGF and its associated receptors, are essential for vasculogenesis during embryonic development. Transgenic mice in which either Ang-1 or Tie-2 is disrupted fail to develop fully functional cardiovascular systems, and either knockout induces embryonic lethality (17, 18). Understanding the coordinated actions of VEGF and Ang-1 during blood vessel development and during angiogen-esis in the adult is hoped to lead to therapeutic regulation of angiogenesis in a variety of clinically relevant states including promotion of vessel growth in wound healing or inhibition of angiogenesis in solid tumors
