Abstract
For a long time, the morphological study of astrocytes relied on immunostaining for astrocyte markers like GFAP, vimentin, or S100β. Though powerful, this method has several drawbacks, most notably that it does not reveal the full extent of individual cells. Modern labeling techniques and the availability of transgenic mice have circumvented this difficulty. Single-cell labeling techniques have revealed normal and reactive astrocytes in their true three-dimensional structure. It has furthermore become clear that astrocyte reactivity is a complex process that depends on the type of astrocyte, the nature of the injury, and the time that has passed since injury. Protoplasmic astrocytes tile the brain parenchyma and maintain their domain organization after at least some types of injury. Fibrous astrocytes do not tile and show a biphasic reaction to injury: a first phase of process retraction followed by a second phase of re-extension of processes.
