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 ...
Ependymal cells, also named ependymocytes, line the spinal cord and the ventricular system of the brain. These cells are involved in the creation and secretion of cerebrospinal fluid (CSF) and beat their cilia to help circulate the CSF and make up the blood-CSF barrier. They are also thought to act as neural stem cells. [15] CNS: Radial glia

Peroxisome proliferator activated receptor gamma 1-alpha coactivator (PGC-1 alpha) is a specific myokine since it stimulates satellite cells, but stimulates M1 and M2 macrophages; M1 macrophages release interleukin 6 (IL-6), Insulin growth factor type 1 and vascular endothelial growth factor (VEGF), while M2 macrophages mainly secrete IGF-1 ...
Oligodendrocytes are a type of glial cell, non-neuronal cells in the central nervous system.They arise during development from oligodendrocyte precursor cells (OPCs), [8] which can be identified by their expression of a number of antigens, including the ganglioside GD3, [9] [10] [11] the NG2 chondroitin sulfate proteoglycan, and the platelet-derived growth factor-alpha receptor subunit (PDGF ...
1962 - The Telstar communications satellite is powered by solar cells. 1963 - Sharp Corporation produces a viable photovoltaic module of silicon solar cells. 1964 - The satellite Nimbus I is equipped with Sun-tracking solar panels. 1964 - Farrington Daniels' landmark book, Direct Use of the Sun's Energy, published by Yale University Press.
Satellite galaxies that orbit from 1,000 ly (310 pc) of the edge of the disc of the Milky Way Galaxy to the edge of the dark matter halo of the Milky Way at 980,000 ly (300 kpc) from the center of the galaxy, [a] are generally depleted in hydrogen gas compared to those that orbit more distantly. This is because of their interactions with the ...
