Overcoming muscle stem cell aging

open access: yesCurrent Opinion in Genetics & Development, 2023
Reduced muscle strength and mass is one of the hallmarks of physiological aging in humans and can result in severe impairment of the quality of life. In part this is caused by a functional loss of the highly specialized muscle stem cells (MuSCs), which in healthy conditions provide maintenance, growth, and regeneration. Recent progress in understanding

Aging Disrupts Muscle Stem Cell Function by Impairing Matricellular WISP1 Secretion from Fibro-Adipogenic Progenitors

open access: yesCell Stem Cell, 2019
Summary Research on age-related regenerative failure of skeletal muscle has extensively focused on the phenotypes of muscle stem cells (MuSCs). In contrast, the impact of aging on regulatory cells in the MuSC niche remains largely unexplored.

Relayed signaling between mesenchymal progenitors and muscle stem cells ensures adaptive stem cell response to increased mechanical load.

Cell Stem Cell, 2021
Adaptation to mechanical load, leading to enhanced force and power output, is a characteristic feature of skeletal muscle. Formation of new myonuclei required for efficient muscle hypertrophy relies on prior activation and proliferation of muscle stem ...

Muscle Stem Cell Quiescence: Controlling Stemness by Staying Asleep.

Trends in Cell Biology, 2021
Muscle stem cells (MuSCs) are tissue-resident stem cells required for growth and repair of skeletal muscle, that are otherwise maintained in a cell-cycle-arrested state called quiescence. While quiescence was originally believed to be a state of cellular

Muscling in on stem cells

Biology of the Cell, 2006
Skeletal muscle is one of the few adult tissues that possesses the capacity for regeneration (restoration of lost functional tissue) as opposed to repair. This capacity is due to the presence of ‘muscle stem cells’ known as satellite cells. Detailed investigation of these cells over the past 50 years has revealed that both these and other cells within ...

Muscle stem cells

Current Opinion in Cell Biology, 2009
Despite being mainly composed of highly differentiated contractile fibers, the adult skeletal muscle possesses the remarkable ability to regenerate, following injury. The cells that are responsible for this capacity are the satellite cells, a small population of adult stem cells positioned under the basal lamina of muscle fibers and that can give rise ...

Muscle stem cells

The Journal of Pathology, 2002
AbstractSince its discovery four decades ago, the satellite cell of skeletal muscle has been implicated as the major source of myogenic cells involved in growth and repair of muscle fibres. This review not only looks at the role of the satellite cell in these processes but discusses how cells derived from other sources and tissues have recently been ...

The Stat3-Fam3a axis promotes muscle stem cell myogenic lineage progression by inducing mitochondrial respiration

open access: yesNature Communications, 2019
Metabolic reprogramming is an active regulator of stem cell fate choices, and successful stem cell differentiation in different compartments requires the induction of oxidative phosphorylation.

A Muscle Stem Cell Support Group: Coordinated Cellular Responses in Muscle Regeneration

open access: yesDevelopmental Cell, 2018
Skeletal muscle has an extraordinary regenerative capacity due to the activity of tissue-specific muscle stem cells (MuSCs). Consequently, these cells have received the most attention in studies investigating the cellular processes of skeletal muscle ...
