Muscle stem cells from developing children with cerebral palsy: a pilot study KU Leuven
The 16th Meeting of the Interuniversity Institute of Myology (IIM), October 17-20, 2019, Assisi, Italy brought together scientists, pharma and patient organization representatives discussing new results on muscle research. Internationally renowned Keynote speakers presented advances on muscle development, homeostasis, metabolism, and disease. Speakers selected among submitted abstracts presented their new, unpublished data in seven scientific ...
Fetal stem cells and skeletal muscle regeneration: a therapeutic approach KU Leuven
More than 40% of the body mass is represented by muscle tissue, which possesses the innate ability to regenerate after damage through the activation of muscle-specific stem cells, namely satellite cells. Muscle diseases, in particular chronic degenerative states of skeletal muscle such as dystrophies, lead to a perturbation of the regenerative process, which causes the premature exhaustion of satellite cell reservoir due to continuous cycles of ...
Secretome of adipose-derived mesenchymal stem cells promotes skeletal muscle regeneration through synergistic action of extracellular vesicle cargo and soluble proteins KU Leuven
BACKGROUND: The mechanisms underpinning the regenerative capabilities of mesenchymal stem cells (MSC) were originally thought to reside in their ability to recognise damaged tissue and to differentiate into specific cell types that would replace defective cells. However, recent work has shown that molecules produced by MSCs (secretome), particularly those packaged in extracellular vesicles (EVs), rather than the cells themselves are responsible ...
Mechanosensitivity of aged muscle stem cells KU Leuven
During aging, skeletal muscle tissue progressively declines in mass, strength, and regenerative capacity. Decreased muscle stem cell (MuSC) number and impaired function might underlie the aging-related muscle wasting and impaired regenerative capacity. As yet, the search for factors that regulate MuSC fate and function has revealed several biochemical factors within the MuSC niche that may be responsible for the decline in MuSC regenerative ...
Reduced growth rate of aged muscle stem cells is associated with impaired mechanosensitivity KU Leuven
Aging-associated muscle wasting and impaired regeneration are caused by deficiencies in muscle stem cell (MuSC) number and function. We postulated that aged MuSCs are intrinsically impaired in their responsiveness to omnipresent mechanical cues through alterations in MuSC morphology, mechanical properties, and number of integrins, culminating in impaired proliferative capacity. Here we show that aged MuSCs exhibited significantly lower growth ...
Noninvasive Reporter Gene Imaging of Stem Cells: Applications in Striated Muscle Disorders KU Leuven
Stem cells have a huge potential for regenerative medicine as they are able to differentiate towards various cell types and can be expanded to cell numbers sufficient for therapy. However, despite their huge potential results after clinical translation have been mostly disappointing. Therefore, new methods need to be developed to optimize stem cell therapy for using stem cells at their maximum capacity. At present, cells are injected and ...
