angiopoietin

(an″jē-ō-poy-ē′tĭn; -poy′ĕ-tĭn) [ angio- + -poiet(ic) + -in]
Any of several genes (or the proteins they encode) that stimulate new blood vessel formation. The proteins encoded by angiopoietin are found in healthy cardiac endothelium and in diseased tissues such as arthritic joints and malignant tumors.
