Satellite glial cell

For the non-glial progenitor cells, see Satellite cell.

Satellite cells (syn: mantlecells or amphicytes) are flattened Schwann cells, a type of glial cell, lining the exterior surface of neurons in the peripheral nervous system. Satellite cells also surround neuron cell bodies within ganglia. They are thought to have a similar role to astrocytes in the central nervous system (CNS). They supply nutrients to the surrounding neurons and also have some structural function. Satellite cells also act as protective, cushioning cells.
