非洲狼尾草珠心细胞程序死亡过程的超微结构观察

ULTRASTRUCTURAL OBSERVATION ON PROGRAMMED CELL DEATH OF NUCELLUS IN PENNISETUM SQUAMULATUM

摘要:

用透射电子显微镜观察了非洲狼尾草珠心细胞衰亡过程，比较明显的结果是，染色质凝集，核周腔膨大呈袋状，内有包裹着核物质的内膜突起；有些内质网槽库膨大成囊泡，能吞噬细胞质；线粒体结构简化，内嵴消失。

Abstract:

Ultrastructural observations on programmed cell death of nucellus in Pennisetum squamulatum demonstrate that the chromatin of the nucleus of the cell in apoptosis shows a condensation process and that the nuclear envelope becomes swollen by the outer membrane heaving. The inner membrane of nuclear envelope develops some protrusions into the swollen space. The endoplasmic reticulum cisternae dilate. Mitochondria are found to lose cristae.
