Origin and progeny of reactive gliosis: A source of multipotent cells in the injured brain

Reactive gliosis is the universal reaction to brain injury, but the precise origin and subsequent fate of the glial cells reacting to injury are unknown. Astrocytes react to injury by hypertrophy and up-regulation of the glial-fibrillary acidic protein (GFAP). Whereas mature astrocytes do not normal... View More
