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 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 viruses encode their own protein capsids with the aid of helper viruses Satellite nucleic acids do not have capsids, but rely on helper viruses to enclose their genomes Package their genome within a capsid (protein shell) Have an envelope (not all viruses) Host range Plants (most common), mammals, arthropods, bacteria
The name "satellite DNA" refers to the phenomenon that repetitions of a short DNA sequence tend to produce a different frequency of the bases adenine, cytosine, guanine, and thymine, and thus have a different density from bulk DNA such that they form a second or "satellite" band(s) when genomic DNA is separated along a cesium chloride density ...
A satellite galaxy is a smaller companion galaxy that travels on bound orbits within the gravitational potential of a more massive and luminous host galaxy (also known as the primary galaxy). [1] Satellite galaxies and their constituents are bound to their host galaxy, in the same way that planets within the Solar System are gravitationally ...
For example, satellite television signals are transmitted from the satellite on two separate channels at the same frequency using right and left circular polarization. In a home satellite dish, these are received by two small monopole antennas in the feed horn, oriented at right angles. Each antenna is connected to a separate receiver.
The TESS satellite uses an array of wide-field cameras to perform a survey of 85% of the sky. With TESS, it is possible to study the mass, size, density and orbit of a large cohort of small planets, including a sample of rocky planets in the habitable zones of their host stars.
