Crucial role of activin a in tubulogenesis of endothelial cells induced by vascular endothelial growth factor.

abstract：:Apoptosis is a physiological process by which multicellular organisms eliminate unwanted cells. Death factors such as Fas ligand induce apoptosis by triggering a series of intracellular protein-protein interactions mediated by defined motifs found in the signaling molecules. One of these motifs is the death effector d...
