The incidence of myosatellite cells associated with "white" and "red" muscle fibres of the parietal muscle and "red" fibres of the craniovelar muscle was estimated by quantitative electron microscopy in the Atlantic hagfish (Myxine glutinosa, L.). Myosatellite cell nuclei constitute 3, 11 and 23% of the total number of nuclei inside the basal lamina of the three types of muscle fibres, respectively. However, the total number of nuclei is highest in "white" fibres, most of the nuclei belonging to striated muscle cells. Myosatellite cell profiles in transverse sections constitute 23, 41 and 61% of the number of muscle fibre profiles of the three types, respectively. The intervals between adjacent myosatellite cells are approximately 135 micrometer in "white" fibres, approximately 55 micrometer in "red" parietal fibres, and only approximately 25 micrometer in craniovelar fibres. Since craniovelar fibres are also comparatively thin, myosatellite cells constitute a significant fraction of the volume inside the basal lamina in these fibres. The myosatellite cells are approximately 30-50 micrometer long and up to 5 micrometer thick. Some myosatellite cells possess few organelles, whereas others appear to contain many free ribosomes, granular endoplasmic reticulum, prominent Golgi apparatus and lysosome-like bodies.
通过定量电子显微镜对大西洋盲鳗（Myxine glutinosa, L.）顶肌的“白色”和“红色”肌纤维以及颅顶肌的“红色”纤维相关的肌卫星细胞发生率进行了估算。肌卫星细胞核分别占三种类型肌纤维基膜内细胞核总数的3%、11%和23%。然而，“白色”纤维中的细胞核总数最高，大多数细胞核属于横纹肌细胞。横切面上的肌卫星细胞轮廓分别占三种类型肌纤维轮廓数量的23%、41%和61%。“白色”纤维中相邻肌卫星细胞之间的间距约为135微米，“红色”顶肌纤维中约为55微米，而颅顶肌纤维中仅约为25微米。由于颅顶肌纤维也相对较细，肌卫星细胞在这些纤维的基膜内占相当大的体积比例。肌卫星细胞长约30 - 50微米，厚达5微米。一些肌卫星细胞细胞器较少，而另一些似乎含有许多游离核糖体、颗粒内质网、显著的高尔基体和溶酶体样小体。
