| 11. | To re-activate myogenesis, the satellite cells must be stimulated to differentiate into new fibers.
|
| 12. | While the former induces activation and proliferation, the latter causes differentiation of proliferating satellite cells.
|
| 13. | Activated satellite cells also begin expressing muscle-specific filament proteins such as desmin as they differentiate.
|
| 14. | However, long-term fasting almost completely arrests cell mitosis and decreases the number of satellite cells.
|
| 15. | However, Pax7 is expressed prominently after satellite cell differentiation.
|
| 16. | "Cultured meat " may be produced as strips of satellite cells found in muscle tissue.
|
| 17. | Additionally, satellite cells have been shown to fuse with muscle fibers, developing new muscle fibers.
|
| 18. | Previously untrained muscles acquire newly formed nuclei by fusion of satellite cells preceding the hypertrophy.
|
| 19. | Specifically, it allows a brief pulse of proliferation of these satellite cells in response to injury.
|
| 20. | Wnt plays a crucial role in satellite cell regulation and skeletal muscle aging and also regeneration.
