Sympathectomy reduces fiber cross-sectional area, and SM treatment recovers it. TA muscles were treated with either saline or 6-hydroxydopamine (SE) for 2 wk on alternate days. In addition, one group of SE-treated mice received clenbuterol during the last 10 d (SE+SM). Cross-sectional areas (CSA) were determined as previously described (24). Mean CSA ± SEM (n = 6, 12, and 11 muscles for saline, SE, and SE+SM, respectively; ****P < 0.0001).
