Inflating bacterial cells by increased protein synthesis [PDF]

open access: yesMolecular Systems Biology, 2015
Understanding how the homeostasis of cellular size and composition is accomplished by different organisms is an outstanding challenge in biology. For exponentially growing Escherichia coli cells, it is long known that the size of cells exhibits a strong ...

Analysis of cell size effects in atomistic crack propagation [PDF]

open access: yes, 2020
We consider crack propagation in a crystalline material in terms of bifurcation analysis. We provide evidence that the stress intensity factor is a natural bifurcation parameter, and that the resulting bifurcation diagram is a periodic "snaking curve ...

Cell-Size Control [PDF]

open access: yesCold Spring Harbor Perspectives in Biology, 2015
Cells of a given type maintain a characteristic cell size to function efficiently in their ecological or organismal context. They achieve this through the regulation of growth rates or by actively sensing size and coupling this signal to cell division.

What programs the size of animal cells?

open access: yesFrontiers in Cell and Developmental Biology, 2022
The human body is programmed with definite quantities, magnitudes, and proportions. At the microscopic level, such definite sizes manifest in individual cells - different cell types are characterized by distinct cell sizes whereas cells of the same type ...

Cell size distribution in a random tessellation of space governed by the Kolmogorov-Johnson-Mehl-Avrami model: Grain size distribution in crystallization [PDF]

open access: yes, 2008
The space subdivision in cells resulting from a process of random nucleation and growth is a subject of interest in many scientific fields. In this paper, we deduce the expected value and variance of these distributions while assuming that the space ...

Extending the Monod model of microbal growth with memory

open access: yesFrontiers in Marine Science, 2022
Monod’s model describes the growth of microorganisms using a hyperbolic function of extracellular resource concentration. Under fluctuating or limited resource concentrations this model performs poorly against experimental data, motivating the more ...

The Regulation of Cell Size [PDF]

open access: yesCell, 2013
An adult animal consists of cells of vastly different size and activity, but the regulation of cell size remains poorly understood. Recent studies uncovering some of the signaling pathways important for size/growth control, together with the identification of diseases resulting from aberrations in these pathways, have renewed interest in this field ...

Scaling of erythrocyte shape and nucleus size among squamate reptiles: reanalysis points to constrained, proportional rather than adaptive changes

open access: yesRoyal Society Open Science, 2023
Small erythrocytes might be beneficial for blood rheology, as they contribute less to blood viscosity than large erythrocytes. We predicted that rheological disadvantages of larger erythrocytes could be alleviated by relatively smaller nucleus size in ...

Rapamycin supplementation of Drosophila melanogaster larvae results in less viable adults with smaller cells

open access: yesRoyal Society Open Science, 2023
The intrinsic sources of mortality relate to the ability to meet the metabolic demands of tissue maintenance and repair, ultimately shaping ageing patterns.

Identification of transcriptional and metabolic programs related to mammalian cell size [PDF]

open access: yes, 2014
SummaryBackgroundRegulation of cell size requires coordination of growth and proliferation. Conditional loss of cyclin-dependent kinase 1 in mice permits hepatocyte growth without cell division, allowing us to study cell size in vivo using ...
