Growth factors are important molecules mediating both the development as well as adaptive and pathological changes within the cardiovascular system. Growth factors therefore mediate both beneficial and nonbeneficial effects. The beneficial actions include the improvement of endothelial function, stimulation of vascular repair, the formation of new capillaries (angiogenesis), and the growth of collateral arteries (arteriogenesis). These actions represent the conceptual basis for the therapeutic use of growth factors, based on the idea to therapeutically induce or accelerate a given beneficial process. The beneficial effects of growth factors have to be separated from effects where growth factors act as mediators of pathological processes such as atherogenesis and plaque destabilization. This review article focuses on the physiological and beneficial effects of growth factors in the vessel wall and describes and explains the dysfunction of these effects under certain conditions now referred to as "growth factor signal transduction defects".
The discovery of the vascular endothelial growth factor (VEGF) family members VEGF, VEGF-B, placental growth factor (PlGF), VEGF-C and VEGF-D and their receptors VEGFR-1, -2 and -3 has provided tools for studying the vascular system in development as well as in diseases ranging from ischemic heart disease to cancer. VEGF has been established as the prime angiogenic molecule during development, adult physiology and pathology. PlGF may primarily mediate arteriogenesis, the formation of collateral arteries from preexisting arterioles, with potential future therapeutic use in for example occlusive atherosclerotic disease. VEGF-C and VEGF-D are primarily lymphangiogenic factors, but they can also induce angiogenesis in some conditions. While many studies have addressed the role of angiogenesis and the blood vasculature in human physiology, the lymphatic vascular system has until recently attracted very little attention. In this review, we will discuss recent advances in angiogenesis research and provide an overview of the molecular players involved in lymphangiogenesis.
