Formation of Muscle Fibers from Myoblasts01:13

Formation of Muscle Fibers from Myoblasts

6.3K
De novo myogenesis, or the formation of muscle fibers, begins during the early embryonic stages. The skeletal muscle is formed from somites– blocks of embryonic cell layers. The somites are further divided into dermatomes, myotomes, sclerotomes, and syndetomes. Among these, the myotomes give rise to muscle fibers.
Muscle progenitor cells (MPCs) are formed from the myotomes. MPCs express genes that encode the transcription factors Pax3 and Pax7. Along with Pax 3/7, other transcription...

Satellite Stem Cells and Muscular Dystrophy

2.5K
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...

Muscle Recovery and Fatigue01:24

Muscle Recovery and Fatigue

4.6K
Muscle fatigue refers to the decline in a muscle's ability to maintain the force of contraction after prolonged activity. It primarily stems from changes within muscle fibers. Even before experiencing muscle fatigue, one may feel tired and have the urge to stop the activity. This response, known as central fatigue, occurs due to changes in the central nervous system, namely the brain and spinal cord. While there is no single mechanism that induces fatigue, it may serve as a protective...

Background:

  • Protein arginine methyltransferases (PRMTs) are enzymes catalyzing arginine methylation.
  • PRMTs have emerged as critical regulators of skeletal muscle regeneration.
  • The precise mechanisms of PRMT action and substrate regulation in muscle stem cells are not fully understood.

Purpose of the Study:

  • To review recent findings on the roles of specific PRMTs (PRMT1, CARM1/PRMT4, PRMT5, PRMT7) in muscle stem cell fate.
  • To highlight knowledge gaps and future research directions.
  • To explore the therapeutic potential of PRMT inhibitors in muscular disorders and aging.

Main Methods:

  • Literature review and synthesis of recent research findings.
  • Point-of-view discussion on current understanding and future challenges.

Main Results:

  • Specific PRMTs play distinct roles in guiding muscle stem cell fate decisions.
  • Arginine methylation by PRMTs influences key pathways regulating muscle regeneration.

Conclusions:

  • Understanding PRMT functions in muscle stem cells is essential for developing targeted therapies.
  • PRMT inhibitors represent a promising therapeutic avenue for treating muscular disorders and age-related muscle decline.
