The present invention relates to an angiogenesis-inducing method using neural stem cells. According to the present invention, neural stem cells derived from human cerebral tissues release monocyte chemoattractant protein-1 (MCP-1) or Gro, thus exhibiting an angiogenesis effect. When CoCl2 was injected to the neural stem cells of the present invention and when the neural stem cells were cultured in a hypoxia chamber, it was observed that a hypoxia condition was induced to increase the release amounts of MCP-1 and Gro. Therefore, the human cerebral tissue-derived neural stem cells of the present invention can be used to induce angiogenesis.
