Dartmouth Heart Researchers Discover New Defect In Artery Growth

... From the beginning, arteries and veins are different in the way they branch into vascular networks, say Dartmouth heart researchers. They have identified a new defect limited to arterial development. The discovery, reported in the June issue of Developmental Cell, upends some theories about the origins of blood vessels and could change the nature of vascular biology research that seeks to harness the mechanisms of blood vessel growth for treatment. ...
