The occurrence and distribution of two cell types associated with normal and denervated frog skeletal muscle fibers are described. The first is the satellite cell. The general appearance and the number of satellite cells are not affected by long-term denervation. The second type of cell is the invasive cell. Invasive cells penetrate across the basal lamina and up to the core of the muscle fiber, without fusing with it. It is suggested that the origin of invasive cells is extramuscular, probably circulatory. Although invasive cells are more numerous in some denervated muscle, it is established that this is not a direct effect of denervation.
本文描述了与正常和去神经支配的青蛙骨骼肌纤维相关的两种细胞类型的出现和分布。第一种是卫星细胞。长期去神经支配不会影响卫星细胞的总体外观和数量。第二种细胞类型是侵入性细胞。侵入性细胞穿过基膜并直达肌纤维核心，但不与之融合。有人认为侵入性细胞起源于肌肉外，可能来自循环系统。尽管在一些去神经支配的肌肉中侵入性细胞数量更多，但已确定这并非去神经支配的直接作用。
