Normalised mass of hindlimb muscles in wild-type (WT) and STAT5B^−/− mice. Mean (± SEM) mass of a quadriceps, b biceps femoris, c gastrocnemius, d tibialis anterior, e extensor digitorium longus, and f soleus in male WT (black bars), male STAT5B^−/− (light grey bars), female WT (dark grey bars), and female STAT5B^−/− (white bars) mice at 6, 12, and 24 weeks of age (n = 8 per group). Unlike letters within each graph denote significant differences (P < 0.05) between groups at each age only
