Annual Review of Genetics, 2019
The genetic control of the characteristic cell sizes of different species and tissues is a long-standing enigma. Plants are convenient for studying this question in a multicellular context, as their cells do not move and are easily tracked and measured from organ initiation in the meristems to subsequent morphogenesis and differentiation.

A model of cell size regulation
Journal of Theoretical Biology, 1965The kinetics of cell growth and the effects of ploidy and genetic factors on cell size are reviewed. The following model of the mechanism regulating cell size is proposed. Unstable molecules (R1) are present in a constant equilibrium quantity per cell, the quantity being proportional to the amount of DNA in the nucleus.

Anuran Vocal Communication: Effects of Genome Size, Cell Number and Cell Size
Brain, Behavior and Evolution, 2021Significant variation in genome size occurs among anuran amphibians and can affect cell size and number. In the gray treefrog complex in North America, increases in cell size in autotriploids of the diploid (<i>Hyla chrysoscelis</i>) altered the temporal structure of mate-attracting vocalizations and auditory selectivity for these ...

Size Distribution of Lymph Cells
Scandinavian Journal of Haematology, 1970With the presently available equipment (Coulter counter in combination with a multichannel analyzer) reproducible and biologically meaningfull cell volume distributions can be recorded within a short time (2–3 min) from a large sample of cells (105). Lymph cells remain nearly stable for 2–3 hours in lymph with heparin as anticoagulant. On dilution with

Current Opinion in Genetics & Development, 2000
Over the past 25 years, the genetic control of cell size has mainly been addressed in yeast, a single-celled organism. Recent insights from Drosophila have shed light on the signalling pathways responsible for adjusting and maintaining cell size in metazoans.

Trends in Genetics, 2002
To remain viable, cells have to coordinate cell growth with cell division. In yeast, this occurs at two control points: the boundaries between G1 and S phases, also known as Start, and between G2 and M phases. Theoretically, coordination can be achieved by independent regulation of growth and division, or by participation of surveillance mechanisms in ...

Extracellular control of cell size
Nature Cell Biology, 2001Both cell growth (cell mass increase) and progression through the cell division cycle are required for sustained cell proliferation. Proliferating cells in culture tend to double in mass before each division, but it is not known how growth and division rates are co-ordinated to ensure that cell size is maintained.

Cell size relations for sonolysis
Ultrasound in Medicine & Biology, 2004The occurrence of cell lysis following exposure to ultrasound (US) has been well documented; the specifics of the mechanistic process(es) involved have proven to be difficult to characterize. There appear to be two major mechanisms of US-induced cell lysis in vitro, acoustic cavitation and bubble transport. Both involve shear forces.

Cell size versus body size in geophilomorph centipedes
The Science of Nature, 2015Variation in animal body size is the result of a complex interplay between variation in cell number and cell size, but the latter has seldom been considered in wide-ranging comparative studies, although distinct patterns of variation have been described in the evolution of different lineages.

AbstractCellular slime mold amoebae have become a model system for the study of cell motility and the cytoskeleton. A basic problem which all cells face that involves the cytoskeleton is how to control their size. The varied ways in which cellular slime mold amoebae change their cell size‐by changing the size at which division occurs, by cell fusion ...
