Morphology of Proliferating Epithelial Cellular Tissue [PDF]
We investigate morphologies of proliferating cellular tissue using a newly developed numerical simulation model for mechanical cell division. The model reproduces structures of simple multi-cellular organisms via simple rules for selective division and ...

During mitosis, correct bipolar chromosome attachment to the mitotic spindle is an essential prerequisite for the equal segregation of chromosomes. The spindle assembly checkpoint can prevent chromosome segregation as long as not all chromosome pairs ...

Gauchos and ochos: a Wee1-Cdk tango regulating mitotic entry
The kinase Wee1 has been recognized for a quarter century as a key inhibitor of Cyclin dependent kinase 1 (Cdk1) and mitotic entry in eukaryotes. Nonetheless, Wee1 regulation is not well understood and its large amino-terminal regulatory domain (NRD) has

Influence of cell cycle phase on calcification in the coccolithophore Emiliania huxleyi [PDF]
Calcification of the cosmopolitan coccolithophore species Emiliania huxleyi was investigated in relation to the cell division cycle with the use of batch cultures.

SYNCHRONIZATION OF CELL DIVISION [PDF]
A culture of unicellular organisms growing at because events in different clones are not in phase maximal rate under constant conditions contains with each other. cells at all stages of the division cycle. The relaWhen conditions are not constant, as when the tive frequencies of cells of different ages-i.e., the stationary phase is approached, growth ...

p27kip1 at the crossroad between actin and microtubule dynamics
The p27kip1 protein, mainly known as a negative regulator of cell proliferation, has also been involved in the control of other cellular processes, including the regulation of cytoskeleton dynamics.

There are four general ideas about animals that would seldom be challenged: 1) the protoplasm of animals is organized into cells; 2) nearly all cells are so small as to be invisible to the human eye; 3) animals are generally clearly visible because they consist of many cells; but 4) most animals arise from single cells (zygotes).

Proline affects the size of the root meristematic zone in Arabidopsis [PDF]
We reported previously that root elongation in Arabidopsis is promoted by exogenous proline, raising the possibility that this amino acid may modulate root growth.

Reconstruction of the kinetochore: a prelude to meiosis
In eukaryotic organisms, chromosomes are spatially organized within the nucleus. Such nuclear architecture provides a physical framework for the genetic activities of chromosomes, and changes its functional organization as the cell moves through the ...

JAB1/CSN5: a new player in cell cycle control and cancer
c-Jun activation domain-binding protein-1 (Jab1) acts as a modulator of intracellular signaling and affects cellular proliferation and apoptosis, through its existence as a monomer or as the fifth component of the constitutive photomorphogenic-9 ...
