2022年10月19日 · 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. The dorsal root ganglia located on either side of the spinal cord contain the most prominent satellite cells.

Myosatellite cells, also known as satellite cells, muscle stem cells or MuSCs, are small multipotent cells with very little cytoplasm found in mature muscle. [1] Satellite cells are precursors to skeletal muscle cells, able to give rise to satellite cells or differentiated skeletal muscle cells. [2]

2024年2月14日 · The cell bodies of neurons located in sensory and autonomic ganglia are each surrounded by a cellular sheath of small cuboidal cells, known as satellite cells. In light microscopy, usually only their nuclei are identifiable.

2021年5月23日 · Satellite cells (SCs) are skeletal muscle stem cells that grow, maintain, and repair muscle tissue. They account for between 3% and 11% of skeletal muscle tissue and are found between the sarcolemma and basement membrane of the muscle fibers.

Satellite glial cells, formerly called amphicytes, [1] are glial cells that cover the surface of neuron cell bodies in ganglia of the peripheral nervous system. Thus, they are found in sensory, sympathetic, and parasympathetic ganglia.

Satellite cells go into a state of dormancy if the body deems them unnecessary due to a sedentary lifestyle. Researchers have found that satellite cells are activated through various signaling pathways as a response to exercise .

2015年10月20日 · Due to its anatomical location, identification of satellite cells originally relied on electron microscopy, and all cells that were located beneath the basal lamina, and above the sarcolemma of a myofiber were considered satellite cells (Mauro, 1961).

Although first detected in frog muscle, the satellite cell presence was immediately confirmed in rat muscle (Mauro 1961), and it was soon shown to occupy a common anatomic position in the majority of vertebrates (reviewed in Grounds and Yablonka-Reuveni 1993).

Satellite cells are mononuclear progenitor cells found in mature muscle between the basal lamina and sarcolemma. Satellite cells are able to differentiate and fuse to augment existing muscle fibres and to form new fibres.

2011年8月17日 · During postnatal growth, new myonuclei are supplied by muscle satellite cells: resident stem cells located on the surface of a myofibre. Satellite cells then become mitotically quiescent in mature muscle, but remain able to be recruited to provide myoblasts for muscle hypertrophy and repair.
