Vesicle Therapy Helps Aged Mice Gain Muscle Mass

Scientists have developed a promising new method to combat the age-related losses in muscle mass that often accompany immobility after injury or illness. Their technique, demonstrated in mice, arrests the process by which muscles begin to deteriorate at the onset of exercise after a period of inactivity.
