For biological processes, knowing when to slow down is as important as knowing when to step on the accelerator. Take for example muscle stem cells. In a healthy state, these cells mostly lay quiet and rarely divide but upon injury, they bolt into action by dividing and specializing into new muscle cells to help repair … Continue reading The life of a sleeping muscle stem cell is very busy

An unexpected link: immune cells send muscle injury signal to activate stem cell regeneration
We’ve written many blogs over the years about research focused on muscle stem cell function . Those stories describe how satellite cells, another name for muscle stem cells, lay dormant but jump into action to grow new muscle cells in response to injury and damage. And when satellite function breaks down with aging as well as … Continue reading An unexpected link: immune cells send muscle injury signal to activate stem cell regeneration
Scientists find new stem cell target for regenerating aging muscles
Today I’m going to use our former governor Arnold Schwarzenegger as an example of what happens to our muscles when we age. One of Arnold’s many talents when he was younger was being a professional bodybuilder. As you can see in this photo, Arnold worked hard to generate an impressive amount of muscle that landed … Continue reading Scientists find new stem cell target for regenerating aging muscles
Researchers cool to idea of ice bath after exercise
Have you ever had a great workout, really pushed your body and muscles hard and thought “You know what would be good right now? A nice plunge into an ice bath.” No. Me neither. But some people apparently believe that taking an ice bath after a hard workout can help their muscles rebound and get … Continue reading Researchers cool to idea of ice bath after exercise
CIRM-Funded Scientists Test Recipe for Building New Muscles
When muscles get damaged due to disease or injury, the body activates its reserves—muscle stem cells that head to the injury site and mature into fully functioning muscle cells. But when the reserves are all used up, things get tricky. This is especially the case for people living with muscle diseases, such as muscular dystrophy, … Continue reading CIRM-Funded Scientists Test Recipe for Building New Muscles
