Fig. 5. Effect of maternal myostatin Ab on growth performance in (A) male and (B) female offspring. Values are means ± s.d. Body masses were measured from male control mice (N=33), male maternal mstn Ab-induced mice (N=13), female control mice (N=31) and female maternal mstn Ab-induced mice (N=13). Asterisks indicate a significant difference in body mass between mstn Ab-induced and control groups at the same age (P<0.05).
