Comparison of expression of growth regulating genes in skeletal muscle between genotypes at postnatal days 21, 42 and 70. Plotted values are least squares means displayed with 95% confidence interval bars of wild type (open bars) and myostatin null (hatched bars) mice. Fold change is compared to the average wild type male 70-day-old expression. Days lacking a common superscript (a,b,c) are different (P < 0.05). **indicates that means within day are different (P ≤ 0.01) between genotypes.
