Mechanisms of polyploidization of albumen gland cells of S. lauta have been studied using squash preparations in combination with autoradiography of DNA synthesis. During the growth period of the gland normal and abnormal (polyploidizing) mitoses were noticed in addition to endomitoses. Diploid foot cells and poorly differentiated secretory cells are reproduced by the normal mitosis (2c : 2c). These poorly differentiated secretory cells go then through polyploidization by different means… Expand
Endopolyploidy as a morphogenetic factor of development
TLDR
Endopolyploidy is an adaptive morphogenetic factor, but its concrete role may differ in different tissues and organisms depending on cell specialization and histogenetic particularities. Expand
Cell Cycle Modification in Trophoblast Cell Populations in the Course of Placenta Formation
TLDR
Polyploidy in Vertebrata suggests that propagation of vertebrates is, probably, due to an advantage of the mitotic cycle that involves a machinery of accurate reproduction of diploid cells over other cell reproduction cycles that result in polyploidization. Expand
Cell cycle progression and different ways of cell and genome reproduction in the invasive trophoblast cells of the silver fox placenta
TLDR
In a minor trophoblast cell population, non-mitotic genome segregation most probably takes part in retention of cell reproductive potential, and Classical endomitosis may be a mode of genome multiplication and correlate with both the persistence and attenuation of cell cycles. Expand
Mitotic catastrophe and endomitosis in tumour cells: An evolutionary key to a molecular solution
TLDR
The role of endomitosis in the somatic reduction of polyploidy during development and its postulated role in the evolution of meiosis are reviewed and incorporated to help interpret the most recent observations in the tumour cell system. Expand
