This image represents the inner workings of a mouse EDL muscle (extensor digitorum longus; it’s the one that allows you to lift your toes off the ground). The muscle pictured here has been stained with fluorescent dyes to mark the nuclei (in blue), the muscle cell outlines (in red), and satellite cells (in orange). The satellite cells are muscle stem cells; they are responsible for repairing your muscle after it has been pulled or injured. Our lab studies muscle injury in hopes to derive a method to enhance the muscle recovery process, which is normally long and arduous.
