Satellite Cells Function Nervous System

Sgcs have been found to play a variety of roles including control over the microenvironment of sympathetic ganglia.

Satellite cells function nervous system.

Thus they are found in sensory sympathetic and parasympathetic ganglia. They are thought to have a similar role to astrocytes in the centra. With neural crest embryonic origins these sgcs are distinct from glia of the cns yet appear to share many functional similarities with astrocytes. When skeletal muscles are damaged they are repaired by stem cells called satellite cells which multiply and transform into replacement muscle cells.

They may also help to regulate the neuronal environment and be involved in neurotransmission. Satellite cells are small flattened cells found in the ganglia of the peripheral nervous system ganglion collection of cell bodies. Satellite cells location structure and function. Researchers have yet to determine the specific functions of satellite cells but it is generally assumed that they help regulate and stabilize the environment around ganglion cell bodies.

They are highly sensitive to injury and inflammation and appear to contribute to pathological states such as chronic pain. Satellite glial cells are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system. Satellite cells indicated by red arrows glial cells that surround some neurons in the peripheral nervous system. Young blood rejuvenates old mice.

The skeletal muscle satellite cell. Satellite glial cells sgcs ensheath the somata of sensory neurons located in dorsal root and trigeminal ganglia. Satellite cells are similar in function to astrocytes small cells that surround neurons in sensory sympathetic and parasympathetic ganglia helping to regulate the external chemical environment.
