Missing proteins delayed muscle repair in middle-aged mice
In an injury experiment, 12-month-old mice lacking three related proteins had smaller regenerating muscle fibers after seven days than mice with the proteins.In an injury experiment, 12-month-old mice lacking three related proteins had smaller regenerating muscle fibers after seven days than mice with the proteins.
Mouse studyMuscle
Who was studiedMiddle-aged mice, seven days, against age-matched wild-type mice
What changedAfter seven days, regenerating muscle fibers were smaller in mice lacking the proteins than in mice retaining them
The catchDelayed repair was inferred from regenerating muscle fiber size
