Summary
Induced pluripotent stem cell-derived myogenic progenitors (iMPs) show promise for muscle regeneration. This study explores enhancing iMP generation and engineering them for novel therapeutic functions beyond current applications.
Area of Science:
- Stem cell biology
- Regenerative medicine
- Skeletal muscle research
Background:
- Induced pluripotent stem cells (iPSCs) can generate myogenic progenitors (iMPs) for tissue regeneration.
- Current iMP protocols produce immature cells resembling Pax7+ adult muscle stem cells.
- Therapeutic applications primarily focus on muscular dystrophies, overlooking traumatic injuries.
Purpose of the Study:
- To review protocols for enhancing iMP generation, purification, and maturation.
- To introduce the concept of engineering iMPs for enhanced post-transplantation functions.
- To envision novel therapeutic applications for engineered iMPs.
Main Methods:
- Review of existing protocols for iMP generation and maturation.
- Discussion of strategies for cell purification.
- Conceptual framework for engineering iMPs with novel functions.
Main Results:
- Protocols exist for producing potent but immature iMPs.
- Engineering iMPs offers potential for functions beyond native capacities.
- Underexplored therapeutic applications exist for traumatic muscle injuries.
Conclusions:
- Enhanced iMP generation and engineering hold significant therapeutic potential.
- Engineering iMPs can lead to novel applications in regenerative medicine.
- Further research into engineered iMPs is warranted for skeletal muscle repair.

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...

4.8K
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...

2.8K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Stem cells are undifferentiated cells that divide and produce different cell types. Ordinarily, cells that have differentiated into a specific cell type are terminally differentiated; however, scientists have found a way to reprogram these mature cells so that they dedifferentiate and return to an unspecialized, proliferative state. These cells are pluripotent like embryonic stem cells—able to produce all cell types—and are called induced pluripotent stem cells (iPSCs).

The ability of induced pluripotent stem cells or iPSCs to differentiate into most body cell types has stimulated repair and regenerative medicine research over the past few decades. iPSC-derived blood cells, hepatocytes, beta islet cells, cardiomyocytes, neurons, and other cell types can repair injuries or regenerate damaged tissue in diseases such as diabetes and neurodegenerative disorders.
