Researchers have discovered a new mechanism responsible for the growth of blood vessel tumors that can cause facial deformities in infants and young children, paving the way for an antibody-based treatment to remove cells that fuel the tumors' growth. Blood vessel tumors require macrophages, a type of white blood cells, to develop. In studying these cells' role in tumor development, researchers determined that a protein called MCP-1 "recruits" macrophages to the vascular tumor site.
