Types of Astrocytes

In 1983, M. C. Raff et al. discovered that tissue samples originating from the optic nerves of rats contained two morphologically distinct types of astrocytes.

  • So-called "Type 1 astrocytes" had a fibroblasts appearance and resided in both gray matter and white matter.
  • "Type 2 astrocytes" had a neuron-like appearance and resided in white matter alone (Sherman, Chris).

Famous quotes containing the word types:

    Science is intimately integrated with the whole social structure and cultural tradition. They mutually support one other—only in certain types of society can science flourish, and conversely without a continuous and healthy development and application of science such a society cannot function properly.
    Talcott Parsons (1902–1979)
