Abstract

Summary

The German Priority Research Program “Angiogenesis” (www.angiogenese.de) hosts a biannual meeting in the Kloster Seeon in Southern Germany. The 2^nd Kloster Seeon Meeting “Angiogenesis: Molecular Mechanisms and Functional Interactions” was held in September 2002. It included sessions on hypoxia, the biology of endothelial precursor cells, angiogenic growth factors including VEGFs, the angiopoietins, ephrins, and FGFs, mechanisms of vascular sprouting and cell-cell contacts during angiogenesis, angiogenic signaling, lymphangiogenesis, angiogenesis during tumor invasion and metastasis, and on novel angiomanipulatory therapies. This report summarizes the key findings reported during the platform presentations of the meeting.

Keywords
