title: A study on amitosis of the nucleus of the mammalian cell. I. A study under the light and transmission electron microscope.
abstract: The experiments were conducted on two species of experimental animals: mice and rats. The mice were poisoned by CCl4, whereas the rats had a hepatectomy in order to remove a larger part of the left lobe of the liver. 5 samples of human liver cancer tissue were examined by routine methods. The phenomena of amitosis were studied. In addition to more features of amitosis, many intranuclear structures characteristic of amitosis were found in the carcinoma tissue. The authors propose to divide the nuclear amitosis process into 4 stages and try to design a diagrammatic picture of amitosis in order to illustrate that also by amitosis chromatin can be reproduced and equally distributed to the daughter cells, so that the continuity and precision of gene threads is guaranteed in the daughter cells. The study discusses the functional significance of nuclear amitosis.
