Influence of cell cycle phase on calcification in the coccolithophore Emiliania huxleyi [PDF]

open access: yes, 2008
Calcification of the cosmopolitan coccolithophore species Emiliania huxleyi was investigated in relation to the cell division cycle with the use of batch cultures.

STOCHASTIC DYNAMICS OF CELL LINEAGE IN TISSUE HOMEOSTASIS. [PDF]

open access: yes, 2019
During epithelium tissue maintenance, lineages of cells differentiate and proliferate in a coordinated way to provide the desirable size and spatial organization of different types of cells.

Is Cell Size Important? [PDF]

open access: yesCell Cycle, 2007
Cell size plays an indirect role in cell proliferation, as cells must double in size before dividing. Cell size is largely determined by the activity of RNA polymerase I that controls ribosomal RNA synthesis and ribosome biogenesis. The type 1 insulin-like growth factor receptor (IGF-IR) and its docking protein, insulin receptor substrate-1 (IRS-1 ...

Variations of endoreduplication and its potential contribution to endosperm development in rice (Oryza sativa L.)

open access: yesPlant Production Science, 2019
Endoreduplication is the phenomenon by which cells increase their ploidy. Endoreduplication is initiated by the transition from the mitotic cell cycle to the endocycle, in which DNA replication occurs without a subsequent chromosome separation and ...

Finite size effects in Neutron Star and Nuclear matter simulations [PDF]

open access: yes, 2014
In this work we study molecular dynamics simulations of symmetric nuclear matter using a semi-classical nucleon interaction model. We show that, at sub-saturation densities and low temperatures, the solutions are non-homogeneous structures reminiscent of

Cellularity of porcine adipose tissue: effects of growth and adiposity

open access: yesJournal of Lipid Research, 1977
Adipose tissue, from two depots in pigs of three breeding groups with different propensities to fatten, was characterized in terms of weight of the adipose tissue organ, adipose cell number, and mean cell volume as determined by electronic counting of ...

Cell size, body size and Peto’s paradox

open access: yesBMC Ecology and Evolution, 2022
AbstractCarcinogenesis is one of the leading health concerns afflicting presumably every single animal species, including humans. Currently, cancer research expands considerably beyond medicine, becoming a focus in other branches of natural science.

Using microelectrode models for real time cell-culture monitoring [PDF]

open access: yes, 2011
This paper proposes a cell-microelectrode model for cell biometry applications, based on the area overlap as main parameter. The model can be applied to cell size identification, cell count, and their extension to cell growth and dosimetry protocols ...

The TOR Signaling Pathway in Spatial and Temporal Control of Cell Size and Growth

open access: yesFrontiers in Cell and Developmental Biology, 2017
Cell size is amenable by genetic and environmental factors. The highly conserved nutrient-responsive Target of Rapamycin (TOR) signaling pathway regulates cellular metabolic status and growth in response to numerous inputs.

Fruit shape loci sun, ovate, fs8.1 and their interactions affect seed size and shape in tomato

open access: yesFrontiers in Plant Science, 2023
Seed size and shape are not only critical for plant reproduction and dispersal, but also important agronomic traits. Tomato fruit shape loci sun, ovate and fs8.1 regulate the morphology of fruit, flower, leaf and stem, and recently their functions in ...
