研究了蝾螈幼体四肢骨骼肌组织中肌管的超微结构和肌原纤维形成过程。直径为100 Å的纤维群在肌原纤维形成期间和之后出现。这个群体除了形成肌动蛋白和肌凝蛋白丝外，可能并不直接促进肌原纤维的形成。相反，它可能代表一个细胞骨架网络，最终主要分布在老肌原纤维的Z带水平上，并与之成直角。
Developing myotubes in skeletal muscle tissue from the limbs of larval newts have been examined with respect to the ultrastructure and sequence of events accompanying myofibril formation. A population of filaments having a diameter of 100 Å is found to occur throughout and beyond the period of myofibrillogenesis. This population is in addition to developing actin and myosin filaments and probably does not contribute directly to myofibril formation. Rather it may represent a cytoskeletal network which ultimately becomes principally disposed around and at right angles to older myofibrils at the level of their Z‐bands.
