Phagocytosis of naturally degenerating cells, by healthy myocardial cells of the bulbus cordis of 5--7-day chick embryos, was studied by electron microscopy. Myocardial cells showed cell processes surrounding dead cell fragments. The cell fragments appeared to be internalized later and digested within phagosomes. Ruthenium red was employed to ascertain whether the cell fragments were in fact internalized or located in pockets of the cell membrane. The results are discussed in the light of present knowledge of phagocytosis.
通过电子显微镜研究了5至7日龄鸡胚心脏球部健康心肌细胞对自然退化细胞的吞噬作用。心肌细胞显示出围绕死亡细胞碎片的细胞突起。细胞碎片似乎随后被内化并在吞噬体内被消化。使用钌红来确定细胞碎片是否实际上被内化或位于细胞膜的凹陷处。根据目前关于吞噬作用的知识对结果进行了讨论。
