Publisher Summary This chapter discusses the cell polyploidy and its relation to tissue growth and function. Cytophotometry established a fundamental similarity between polyploidy and polyteny, their common feature being multiple doubling of DNA in the cell. The occurrence and properties of polyploid cell populations is discussed. Polyploid nuclei have been found in protozoa and in the cells of many metazoa, both animals and plants. The common property of polyploid cell populations is retention… Expand
Polyploidy: occurrence in nature, mechanisms, and significance for the megakaryocyte-platelet system.
TLDR
The objective of this review is to briefly describe the different cell cycle alterations that may lead to high ploidy, while focusing on the megakaryocyte and the importance of high ploidsy to platelet level and function. Expand
Biological significance of liver cell polyploidy: an hypothesis.
TLDR
The aberrant polyploid genome of hepatocytes is assumed to be the cytogenetic basis for some chronic liver diseases in man and the prerequisite factors for unbalanced cell genome formation are adduced. Expand
Significance of polyploidy in megakaryocytes and other cells in health and tumor disease
TLDR
Evidence that the heterogeneity of platelets mostly depends on the different polyploidy classes of the megakaryocytes from which they are derived is shown, which could have consequences for hemostatic disorders in several human diseases, particularly in malignancy. Expand
Polyploidy and liver proliferation.
TLDR
The current state of understanding about howpolyploidization is regulated during normal and pathological liver growth is reviewed, and detail by which mechanisms hepatocytes become polyploid is reviewed. Expand
Roads to polyploidy: The megakaryocyte example
TLDR
Overall, polyploidy is associated with an orchestrated change in expression of several genes, of which, some may be a result of high ploidy and hence a determinant of a new cell physiology, while others are inducers ofpolyploidization. Expand
Role of Polyploidy in Reproductive Organs and Tissues
TLDR
After more than 30 years of research on the nuclear cytology of differentiated tissues, it is now clear that the “supernumerary chromonemal reproduction” at interphase, better called “chromosome endoreduplication” (Levan and Hauschka 1953), is the commonest and most widespread process of cell polyploidization in both plants and animals. Expand
Polyploidization of liver cells.
TLDR
The current state of understanding about how polyploidization is regulated during normal and pathological liver growth is reviewed and detail by which mechanisms hepatocytes becomepolyploid is reviewed. Expand
Human hepatocyte polyploidization kinetics in the course of life cycle
TLDR
The processes of polyploidization in normal human liver parenchyma from 155 individuals aged between 1 day and 92 years were investigated by Feulgen-DNA cytophotometry and it was shown that during postnatal liver growth the polyploidsization process is similar to that in the rat. Expand
CHRONOCRISIS: When Cell Cycle Asynchrony Generates DNA Damage in Polyploid Cells
  • S. Gemble, R. Basto
  • Medicine, Biology
  • BioEssays : news and reviews in molecular, cellular and developmental biology
  • 2020
TLDR
The discussion is framed around a recent study showing that asynchronous cell cycle progression (an event that is named “chronocrisis”) of different nuclei from a polyploid cell can generate DNA damage at mitotic entry. Expand
Nuclear DNA content in differentiated tissues of sunflower (Helianthus annuus L.)
TLDR
It was found that tissue differentiation in sunflower occurs in the diploid condition, cells being arrested in the DNA presynthetic phase (G1), and Cytological and autoradiographic analyses after3H-thymidine incorporation reveal that polyploidy in the tapetal cells is due to chromosome endoreduplication.

Polyploïdie somatique dans le foie de rat: I. Le rôle des cellules binucléées dans la genèse des cellules polyploïdes
TLDR
It is impossible to induce the formation of polyploid cells in a liver which does not contain any binuclear cells (partial hepatectomy on animals less than 3 weeks old), which clearly show that the binuclear phase is an intermediate stage between a given state ofpolyploidy and the immediately superior one.

TLDR
The present investigation was undertaken to determine whether cell volume is directly proportional to ploidy, and the departure from the expected 2:4:8 appears to be the results of systematic errors introduced by the measurement of objects of different sizes in an aperture of fixed size. Expand

The physiology of polytene chromosomes is discussed: there is no evidence that the intense activities of hypertrophied salivary cells in Diptera depend on continuous monitoring at transcription level, and the use of terminology examined. Expand
Nucleoprotein Changes in Plant Tumor Growth
TLDR
The normal relation between DNA synthesis and mitosis was disrupted in tumor tissue, Nevertheless, clearly defined DNA classes, as found in homologous normal tissues, were maintained in the tumor at all times. Expand

The mitotic and endomitotic nuclear cycle in Allium carinatum
TLDR
Since the rate of RNA synthesis exhibits a closer relationship to the nuclear volume than to thenuclear DNA content, the synthesis of specific proteins might be necessary to make the reduplicated DNA available as a template. Expand
Formation and division of binucleated cells in kidney cell cultures of microtus agrestis
TLDR
Observations of living cells under the phase contrast microscope showed that binucleated cells can arise by nuclear mitosis without cytoplasmic division, suggesting the possibility of somatic segregation of complete haploid sets. Expand

TLDR
Polyploid cells in matched sets provide models which can be effectively used for the analysis of growth and cytogenetic changes and evidence was found that cell shape and dimensional patterns are unaltered by changes in ploidy level. Expand
The relation of DNA synthesis and mitosis in tobacco pith tissue cultured in vitro
TLDR
It appears impossible to predict whether a 4 C nucleus in differentiated tissue would, upon restoration of conditions conducive to DNA synthesis and mitosis, enter a diploid mitosis or, after undergoing DNA synthesis, a tetraploid one. Expand

TLDR
Value of the labelin g index of polyploid hepatic cells is genera lly smaller than that of diploid cells, and the value of the labeling index of binucleate cells is also smallerthan that of mononucleat e cells, which strongly suggest that the proliferative capacity of liver cells is reduced with polyploids.
