Satellite Cells Function Nervous System

Their role is not fully understood but it is thought they provide nutrient support and protection.

Satellite cells function nervous system.

Satellite glial cells sgcs ensheath the somata of sensory neurons located in dorsal root and trigeminal ganglia. They are highly sensitive to injury and inflammation and appear to contribute to pathological states such as chronic pain. Both satellite glial cells and schwann cells are derived from the neural crest of the embryo during development. With neural crest embryonic origins these sgcs are distinct from glia of the cns yet appear to share many functional similarities with astrocytes.

Sgcs have been found to play a variety of roles including control over the microenvironment of sympathetic ganglia. Satellite cells are small flattened cells found in the ganglia of the peripheral nervous system ganglion collection of cell bodies. Satellite glial cells are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system. 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.

They are thought to have a similar role to astrocytes in the centra. They may also help to regulate the neuronal environment and be involved in neurotransmission. Young blood rejuvenates old mice. 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.

Thus they are found in sensory sympathetic and parasympathetic ganglia. The stem cell that came in from the cold. Satellite cells indicated by red arrows glial cells that surround some neurons in the peripheral nervous system.
