Mechanism for regulation of growth and differentiation of adult muscle stem cells is revealed
During muscle regeneration, which is a natural response to injury and disease, environmental cues cause adult muscle stem cells (satellite cells) to shift from dormancy to actively building new muscle tissue. view more (2007-12-10)
Don't move a muscle: Evolutionary insight into myogenesis
In a paper released online ahead of its scheduled December 15th publication date, Dr. Michael Krause (NIH) and colleagues detail the transcription network that drives muscle development in the roundworm C. elegans, and make a strong argument for an evolutionarily conserved program of myogenesis in all animals. view more (2006-12-07)
Human muscle-derived stem cells effective in animal models of incontinence
Human muscle-derived cells, pluripotent stem cells found in muscle, have been used to cure stress urinary incontinence in animal models, a finding which signals that these cells are prime candidates to treat the condition in adults. view more (2005-09-01)
Experts Solve Christmas Turkey Teaser
Experts from the University of Sheffield have identified the genetic switch that helps explain which parts of the Christmas turkey are white meat and which are dark. Professor Philip Ingham and his colleagues have worked on fish muscle cells to find a genetic switch that determines muscle fibre type in all vertebrates. The full paper will be... view more...

Dynamic sonography accurate in diagnosing muscle tears
Dynamic sonography is useful in the diagnosis, management and follow-up of muscle tears and hematomas, according to a recent study conducted by researchers from Khoula Hospital in Muscat, Oman. view more (2007-05-25)
Potential therapy for congenital muscular dystrophy
Current research suggests laminin, a protein that helps cells stick together, may lead to enhanced muscle repair in muscular dystrophy. view more (2008-12-30)
Heart derived stem cells develop into heart muscle
Dutch researchers at University Medical Center Utrecht and the Hubrecht Institute have succeeded in growing large numbers of stem cells from adult human hearts into new heart muscle cells. view more (2008-04-24)
Stretching does not prevent muscle soreness
Stretching before or after exercise does not prevent muscle soreness or reduce risk of injury, finds a study in this week's BMJ. Researchers in Australia reviewed five studies, involving 77 subjects, on the effect of stretching on muscle soreness. In all studies, participants were healthy young adults. Three studies evaluated stretching after... view more... (2002-08-28)
Key finding in rare muscle disease
The finding is in the current issue of Annals of Neurology, a leading international neurology journal, in work led by Professor Nigel Laing and Dr Kristen Nowak of the Laboratory for Molecular Genetics at the Western Australian Institute for Medical Research (WAIMR) and done in collaboration with a number of European researchers. view more (2007-01-18)
Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells. view more (2008-05-28)
Massage after exercise myth busted by Queen's research team
A Queen's University research team has blown open the myth that massage after exercise improves circulation to the muscle and assists in the removal of lactic acid and other waste products. view more (2009-05-08)
Heart attack in a laboratory dish
NWO researchers at Utrecht University have given heart muscle cells a heart attack in the laboratory. This allowed them to observe clearly the change that takes place in the cell membrane during an attack and how the change sometimes leads to the death of the cell. In a healthy cell, one of the components of the membrane, the phospholipids, are... view more... (2001-05-08)
U of MN researchers develop mouse model for muscle disease
Researchers from the University of Minnesota have identified the importance of a gene critical to normal muscle function, resulting in a new mouse model for a poorly understood muscle disease in humans. view more (2006-09-06)
'Mighty mice' made mightier
The Johns Hopkins scientist who first showed that the absence of the protein myostatin leads to oversized muscles in mice and men has now found a second protein, follistatin, whose overproduction in mice lacking myostatin doubles the muscle-building effect. view more (2007-08-29)
Stem cell surprise for tissue regeneration
Scientists working at the Carnegie Institution's Department of Embryology, with colleagues, have overturned previous research that identified critical genes for making muscle stem cells. view more (2009-06-25)
Researchers discover gene mutation thought to control energy levels
This study focused on the gene for AMPK (adenosine monophosphate-activated protein kinase), which controls the amount of energy in our cells by becoming active when fuel stores start to deplete, such as during exercise. view more (2007-09-19)
Gene therapy accelerates healing of damaged skeletal muscle
University of Pittsburgh School of Medicine researchers have successfully used gene therapy to accelerate muscle regeneration in experimental animals with muscle damage, suggesting this technique may be a novel and effective approach for improving skeletal muscle healing, particularly for serious sports-related injuries. view more (2006-06-05)
While focusing on heart disease, researchers discover new tactic against fatal muscular dystrophy
Based on a striking similarity between heart disease and Duchenne muscular dystrophy, researchers at Columbia University Medical Center have discovered that a new class of experimental drugs for heart failure may also help treat the fatal muscular disorder. view more (2009-02-09)
Stimulating muscles may improve musician's dystonia
Therapy that stimulates the hand muscles may help treat the condition called musician's dystonia, a movement disorder that causes muscles spasms in musicians, according to a study published in the December 26, 2007, online issue of Neurology®, the medical journal of the American Academy of Neurology. view more (2007-12-27)
Stem cell breakthrough: Monitoring the on switch that turns stem cells into muscle
In a genetic engineering breakthrough that could help everyone from bed-ridden patients to elite athletes, a team of American researchers-including 2007 Nobel Prize winner Mario R. Capecchi-have created a "switch" that allows mutations or light signals to be turned on in muscle stem cells to monitor muscle regeneration in a living mammal. view more (2009-03-31)
