SnapShot: Cell size control [PDF]
CellCell size exhibits remarkable diversity across and within organisms. Size variation correlates with DNA content and growth rates and is regulated by complex models of cell size control that are yet to be mechanistically defined. To view this SnapShot, open or download the PDF.

Transcriptional and chromatin-based partitioning mechanisms uncouple protein scaling from cell size
Molecular Cell, 2021 Biosynthesis scales with cell size such that protein concentrations generally remain constant as cells grow. As an exception, synthesis of the cell-cycle inhibitor Whi5 "sub-scales" with cell size so that its concentration is lower in larger cells to ...

Cell size: Single cells illuminate the rules of cell size control
Current Biology, 2023A new study uses Chlamydomonas reinhardtii to understand how cell size homeostasis emerges from stochastic individual cell behaviors within a population. The authors find that a simple power law model was a poor predictor of cell size regulation; rather, it is better explained by a modified threshold model.

Why size matters: altering cell size
Current Opinion in Genetics & Development, 2002Several genes involved in growth control have lately been demonstrated to exhibit more potent effects on cell size than on cell proliferation. Many of these genes direct protein and ribosomal synthesis, highlighting the interdependence between cell size and macromolecular content.

Dielectrophoresis of cell-size liposomes
Biochimica et Biophysica Acta (BBA) - Biomembranes, 1994The dielectrophoresis (DEP) behavior of cell size liposomes were studied in the frequency range from 20 kHz to 3 MHz. Liposomes in the size of about 10 microns in diameter were made from egg phosphatidylcholine (PC), egg phosphatidylethanolamine (PE), egg phosphatidylglycerol (PG) and brain phosphatidylserine (PS).

BioEssays, 2000
For many years, it has been believed that diffusion is the principle motive force for distributing molecules within the cell. Yet, our current information about the cell makes this improbable. Furthermore, the argument that limitations responsible for the relative constancy of cell size--which seldom varies by more than a factor of 2, whereas organisms

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

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.
