Ultrastructure of tumor cells during mitosis.

摘要: The fine structure of the mitotic process solid hepatoma cells rat has been described. replication and migration centrioles, appearance disappearance spindle tubules kinetochores, movement chromosomes resemble those reported in other cell systems. It observed that nucleoli persist throughout all stages division. Golgi apparatus retains its discrete entity laminar vesicular components during entire cycle. Remnants nuclear envelopes have phases, even telophase, after reconstruction membrane daughter is completed. Penetration rough endoplasmic reticula into may appear metaphase anaphase. In cytokinesis initiated by symmetrical invagination plasma and, at certain stages, mitochondria move freely region intercellular bridge which connects cells. The activities these tumor represent behavior cellular organelles natural unaltered nutritional environment.
