Cell surface and cell division
Cell Biophysics, 1982A mathematical model of the regulation of cell division is suggested. The model is based on the hypothesis that the process giving rhythm to cell division is located in the cell membrane: i.e., the process of free-radical oxidation of membrane lipids. Much depends on the physical state of the membrane.

The correlation between cell shape elongation and the orientation of the division axis described by early cell biologists is still used as a paradigm in developmental studies. However, analysis of early embryo development and tissue morphogenesis has highlighted the role of the spatial distribution of cortical cues able to guide spindle orientation. In

Journal of Biomechanics, 1979
Abstract We present a model of cell division of a spherical cell which relates the deformation of the cell and the cell membrane to the forces in the contractile ring or furrow region of a dividing cell. The spherical cell of a sea urchin egg is considered as a spherical nonlinear elastic membrane enclosing an incompressible fluid. The results of the

Current Opinion in Cell Biology, 1993
The past couple of years have seen the isolation and characterization of many of the regulatory genes from plants that are thought to be intimately involved in regulation of the cell division cycle. In addition, characterization of plant-specific aspects of the cell division cycle has provided insight into how spatial and temporal controls may be ...

PROTEOMICS, 2017
AbstractCell division requires a coordinated action of the cell cycle machinery, cytoskeletal elements, chromosomes, and membranes. Cell division studies have greatly benefitted from the mass spectrometry (MS)‐based proteomic approaches for probing the biochemistry of highly dynamic complexes and their coordination with each other as a cell progresses ...

The ftsZ gene in Escherichia coli is thought to be an essential gene and to play a pivotal role in cell division. Gene disruption experiments confirmed that ftsZ is an essential gene. Examination of cellular responses to FtsZ depletion indicated that FtsZ was required for division but not for nucleoid segregation. Analysis of mutations within the ftsZ,

With the recent identification of intrinsic cell-fate determinants for asymmetric cell division in several systems, biologists have begun to gain insight into the cellular mechanisms by which these determinants are preferentially segregated into one of the two daughter cells during mitosis so that the daughter cells acquire different fates.

▪ Abstract Formation of the bacterial division septum is catalyzed by a number of essential proteins that assemble into a ring structure at the future division site. Assembly of proteins into the cytokinetic ring appears to occur in a hierarchial order that is initiated by the FtsZ protein, a structural and functional analog of eukaryotic tubulins ...

Asymmetric cell division is a conserved mechanism for partitioning information during mitosis. Over the past several years, significant progress has been made in our understanding of how cells establish polarity during asymmetric cell division and how determinants, in the form of localized proteins and mRNAs, are segregated.

After a survey of the theory and some realizations of self-replicating machines, this paper presents a novel self-replicating loop endowed with universal construction and computation properties. Based on the hardware implementation of the so-called Tom Thumb algorithm, the design of this loop leads to a new kind of cellular automaton made of a ...
