Nature, 1970
Cell growth and division, and the way in which chromosome segregation is coordinated with these events, are discussed in terms of a model based on the concept of a unit cell—the smallest viable bacterium.

Current Opinion in Plant Biology, 2003
Expansins are now generally accepted to be key regulators of wall extension during growth. Several alternative roles for expansins have emerged in which the emphasis of their action is on wall breakdown or softening in processes such as fruit ripening, pollination, germination and abscission.

Costimulation of T-cell growth
Current Opinion in Immunology, 1992The specificity of T-cell recognition is dictated by the interaction of the T-cell receptor with MHC-peptide complexes. The biological consequences of such recognition is determined, however, by costimulatory pathway(s). Recent studies have led to the identification of receptor-counter-receptor pairs that may regulate T-cell costimulation.

Nature, 1973
INVESTIGATIONS have been made using the model for the growth of all abnormal cells suggested by Williams and Bjerknes1. They showed that the mathematics of the problem remained largely the same for different cell lattices, and so, for reasons of programming simplicity, consideration is limitted to growths on square lattices.

Growth Factors and Regulation of Cell Growth
Annual Review of Medicine, 1982A new class of polypeptide hormones known collectively as growth factors has been identified. These polypeptides are able to stimulate DNA synthesis and mitosis of cells cultured in vitro. Growth factors have been isolated from several sources, including platelets, submaxillary glands, pituitary, brain, and medium conditioned by cells grown in vitro ...

Cell length, cell growth and cell division
Nature, 1976When cells of E. coli reach a certain critical length, which is constant in all growth conditions and eqqal to twice the minimum cell length, they abruptly increase their rate of elongation and divide about 20 min later. Chromosome replication terminates at about this same cell length but is not the signal for the change in rate of cell elongation.

Growth control by cell to cell contact
Journal of Supramolecular Structure, 1979AbstractControl of cell growth by cell to cell contact is reviewed with particular emphasis on two systems – contact inhibition of growth observed with Swiss 3T3 cells and the mitogenic stimulation of Schwann cells by dorsal root ganglia neurites.

Curcumin, the active ingredient of turmeric (Curcuma longa) used in culinary and medical practices in Asia, has immense potential for being used in cancer chemotherapy because of its control over the cell growth regulatory mechanisms. The present chapter throws light on the role of curcumin in modulating the various phases of the cell cycle and its ...

Phosphoinositides and Cell Growth
1992The findings described above illustrate how the src kinase can influence several new pathways of inositol phosphate metabolism, both at the membrane level with the production of novel D-3 phosphoinositides and the activation of PI-3 kinase, and at the cytosolic level by altering the expression of certain inositol polyphosphates, in particular Ins(1,4,5,

Coordination of cell growth with cell division
Current Opinion in Genetics & Development, 1999Proliferating cells must increase their mass coordinately with cell division. Recent evidence suggests that coupling of cell growth with cell division might be achieved by making synthesis of activators of cell division particularly sensitive to the capacity of the cell's protein synthesis machinery.
