Pericytes retina
WebSep 1, 2008 · Resident retinal pericytes derive from mesoderm and neural crest during development. A bone marrow origin of pericytes and transdifferentiation of endothelial cells into pericytes have also been demonstrated during postnatal vascular repair and in adult angiogenesis ( 3 – 5 ). WebApr 28, 2024 · The retina and optic nerve are central nervous system structures that are committed by numerous neurodegenerative diseases, such as ischemic optic neuropathy, hereditary optic neuropathies, and glaucoma. When analyzed, the pathophysiology of these conditions reveals an important vascular component.
