通过使用多克隆抗结蛋白抗体和乙酰胆碱酯酶活性的组织化学证明，研究了鸡胚体节中拟肌节形成的开始。肌节细胞仅起源于皮节，而硬结细胞不参与肌节的形成。肌节的形成始于皮节的颅内侧角。从那里开始，肌节的形成同时沿着皮节的内侧和颅侧边缘继续。结果发现，只有已经纵向取向的细胞的颅皮节边缘引起的肌节;细胞的背内侧皮节边缘不有助于肌节。肌节细胞不是通过分层直接起源于上覆皮节的表面。
The onset of nyotome formation in somites of chick embryos was studied by use of a polyclonal antidesmin antibody and by histochemical demonstration of acetylcholine esterase activity. The myotome cells originate from the dermatome only; sclerotome cells do not contributue to the myotome. The formation of the myotome starts in the craniomedial corner of the dermatome. From there the myotome formation continues simultaneously along the medial and the cranial edge of the dermatome. It was found that only the already longitudinally oriented cells of the cranial dermatone edge give rise to the myotome; the cells of the dorsomedial dermatome edge do not contribute to the myotome. Myotome cells do not originate directly from the surface of the overlying dermatome by delamination.
