Satellite glial cells are a type of glia found in the peripheral nervous system, specifically in sensory, [2] sympathetic, and parasympathetic ganglia. [3] They compose the thin cellular sheaths that surround the individual neurons in these ganglia. In a SGC, the cell body is denoted by the region containing the single, relatively large nucleus ...
Satellite cells express a number of distinctive genetic markers. Current thinking is that most satellite cells express PAX7 and PAX3. [6] Satellite cells in the head musculature have a unique developmental program, [7] and are Pax3-negative. Moreover, both quiescent and activated human satellite cells can be identified by the membrane-bound ...
Satellite cells: Satellite glial cells are small cells that surround neurons in sensory, sympathetic, and parasympathetic ganglia. [19] These cells help regulate the external chemical environment. Like astrocytes, they are interconnected by gap junctions and respond to ATP by elevating the intracellular concentration of calcium ions.
Schwann cells or neurolemmocytes (named after German physiologist Theodor Schwann) are the principal glia of the peripheral nervous system (PNS). Glial cells function to support neurons and in the PNS, also include satellite cells, olfactory ensheathing cells, enteric glia and glia that reside at sensory nerve endings, such as the Pacinian corpuscle.
Each cell has several long cytoplasmic protrusions that extend from the cell body and wrap around the sinusoids. [5] The lipid droplets in the cell body store vitamin A as retinyl palmitate. [6] Hepatic stellate cells store 50–80% of the body's vitamin A. [6] The function and role of quiescent hepatic stellate cells is unclear.
A satellite is a subviral agent that depends on the coinfection of a host cell with a helper virus for its replication. Satellites can be divided into two major classes: satellite viruses and satellite nucleic acids. [1] Satellite viruses, which are most
Stellate cells are neurons in the central nervous system, named for their star-like shape formed by dendritic processes radiating from the cell body. These cells play significant roles in various brain functions, including inhibition in the cerebellum and excitation in the cortex, and are involved in synaptic plasticity and neurovascular coupling.
Satellite cells are described as quiescent myoblasts and neighbor muscle fiber sarcolemma. [4] They are crucial for the repair of muscle, but have a very limited ability to replicate. Activated by stimuli such as injury or high mechanical load, satellite cells are required for muscle regeneration in adult organisms. [4]
