Summary
The immune system, particularly myeloid cells, plays a crucial role in muscle regeneration. These cells influence muscle repair through direct and indirect mechanisms, impacting tissue healing.
Area of Science:
- Muscle regeneration
- Immunology
- Tissue repair
Background:
- Stem cell-focused muscle regeneration research is advancing.
- The microenvironment significantly impacts regeneration success.
- The immune system is a key factor in muscle repair complexity.
Purpose of the Study:
- To highlight recent discoveries on myeloid cell roles in muscle regeneration.
- To emphasize the co-regulation between muscle and myeloid cells during regeneration.
Main Methods:
- Review of recent scientific literature on myeloid cell involvement in muscle regeneration.
- Analysis of inductive mechanisms employed by myeloid cells.
Main Results:
- Myeloid lineage immune cells regulate tissue regeneration.
- These cells employ instructive (direct on muscle) and permissive (angiogenesis, fibrosis modulation) mechanisms.
- Specific myeloid cell populations exert inductive effects on muscle regeneration.
Conclusions:
- Myeloid cells are critical regulators of muscle regeneration success.
- Understanding the interplay between muscle and myeloid cells is key to optimizing regenerative therapies.

1.7K
Satellite stem cells or myosatellite cells are quiescent stem cells that Alexander Mauro first identified in 1961. These cells are located between the sarcolemma, the plasma membrane of muscle fibers, and the basal lamina, the connective tissue sheath covering it. These mononucleated cells are activated in response to muscle injury, can transform into myoblasts, and may form or repair muscle fibers. Myosatellite cells can provide additional myonuclei for muscle regeneration or return to a...

50.3K
Paracrine signaling allows cells to communicate with their immediate neighbors via secretion of signaling molecules. Such a signal can only trigger a response in nearby target cells because the signal molecules degrade quickly or are inactivated if not taken up. Prominent examples of paracrine signaling include nitric oxide signaling in blood vessels, synaptic signaling of neurons, the blood clotting system, tissue repair/wound healing, and local allergic skin reactions. Nitric oxide as a...

16.6K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate with the environment.
Cells respond to many types of information, often through receptor proteins positioned on the membrane. For example, skin cells respond to and transmit touch...
