SATELLITE CELL Meaning and
Definition
-
A satellite cell is a type of cell found in muscle tissue, particularly in skeletal muscles. These cells are typically located beside muscle fibers and play a crucial role in muscle development, repair, and regeneration. They are named "satellite" cells due to their peripheral position next to the muscle fibers.
Satellite cells are undifferentiated, meaning they are not specialized or matured. However, when muscle fibers are damaged or injured, satellite cells become activated and undergo a process called myogenesis. During myogenesis, these cells divide and differentiate into specialized muscle cells called myoblasts. The myoblasts then fuse together to repair or replace the damaged muscle fibers, resulting in muscle growth and regeneration.
In addition to their role in muscle repair, satellite cells also contribute to muscle hypertrophy or muscle growth by adding new muscle proteins and increasing the number of myonuclei in existing muscle fibers. This allows for greater muscle strength and performance.
Satellite cells are controlled by various growth factors and hormones, such as insulin-like growth factor (IGF-1) and testosterone, which stimulate their activation. They play a fundamental role in maintaining muscle homeostasis and are essential for the adaptation of skeletal muscles to exercise, as well as recovery from injuries or diseases affecting muscle tissue.
Overall, satellite cells are a vital component of muscle tissue and exert significant influence on muscle development, repair, and growth.

Etymology of SATELLITE CELL
The word "satellite cell" has its roots in Latin. The term "satellite" comes from the Latin word "satelles", which means "attendant" or "companion". In the context of biology, a satellite cell is a type of cell that is associated with and supports the function of another cell type, particularly in muscle tissue. These cells were named "satellite cells" due to their close proximity to muscle fibers, acting as companions or attendants to the muscle cells.
