title: [Neurosurgical embryology. Part 8: Post-natal angiogenesis and remodeling].
abstract: Post-natal angiogenesis (microvascular proliferation) and remodeling (modifications of diameter and wall thickness) occur in various physiological circumstances including adaptation to exercise or wound healing. The formation of a new vessel is submitted to the combinative action of growth factors. New endothelial cells migrate, proliferate, differentiate and attract pericytes and future smooth muscle cells to create the new vessel. Powerful stimuli leading to remodeling and to the creation of new vessels are mainly represented by hemodynamic forces generated by pressure and blood flow, and by hypoxia. Our purpose is to overview the molecular mechanisms and the stimuli giving rise to these processes.
