The embryonic cell lineage of the nematode Caenorhabditis elegans

by J. E. Sulston, H. R. Horvitz - Dev. Biol , 1983
"... The number of nongonadal nuclei in the free-living soil nematode Caenorhabditis elegans increases from about 550 in the newly hatched larva to about 810 in the mature hermaphrodite and to about 970 in the mature male. The pattern of cell divisions which leads to this increase is essentially invarian ..."

Themes and variations in prokaryotic cell division

by William Margolin - FEMS Microbiol. Rev
"... Perhaps the biggest single task facing a bacterial cell is to divide into daughter cells that contain the normal complement of chromosomes. Recent technical and conceptual breakthroughs in bacterial cell biology, combined with the flood of genome sequence information and the excellent genetic tools ..."

in several model systems, have shed new light on the mechanism of prokaryotic cell division. There is good evidence that in most species, a molecular machine, organized by the tubulin-like FtsZ protein, assembles at the site of division and orchestrates the splitting of the cell. The determinants that target

Thymic selection and cell division

by Bettina Ernst, Charles D. Surh, Jonathan Sprent , 1995
"... Cell division during thymic selection was studied with a system in which purified populations ofT cell antigen receptor (TCR.)- CD4+8 + (double-positive [DP]) cells and fetal thymic epithelial cells (TEC) were reaggregated in tissue culture. In this system, immature DP cells differentiate into matur ..."

"... During the development of multicellular organisms, organogenesis and pattern formation depend on formative divisions to specify and maintain pools of stem cells. In higher plants, these activities are essential to shape the final root architecture because the functioning of root apical meristems and ..."

cell division complex

by unknown authors
"... Rosalba Lagos 1 and Octavio Monasterio 1* Background: Bacterial division is produced by the formation of a macromolecular complex in the middle of the cell, called the divisome, formed by more than 10 proteins. This process can be divided into two steps, in which the first is the polymerization of F ..."

IMAGES OF “CELL DIVISION ” ON THE INTERNET

by Lucia Prinou, Krystallia Halkia
"... The use of images in teaching biology is considered to be of great importance for the comprehension of concepts by secondary school students. Important questions for the didactics of biology, which might be of interest to answer, are concerned with the way images, used in biology classrooms, are sel ..."

This paper presents a research, which is focused on the subject of cell division and it investigates the sort of relevant images that are to be found in sites on the WEB. Moreover, it studies the reactions of students, in the last year

Cell division and migration in a ‘genotype’ for neural networks

by Angelo Cangelosi, Domenico Parisi, Stefano Nolfi - Netw. Comput. Neural Syst , 1994
"... Much research has been dedicated recently to applying genetic algorithms to populations of neural networks. However, while in real organisms the inherited genotype maps in complex ways into the resulting phenotype, in most of this research the development process that creates the individual phenotyp ..."

phenotype is ignored. In this paper we present a model of neural development which includes cell division and cell migration in addition to axonal growth and branching. This reflects, in a very simplified way, what happens in the ontogeny of real organisms. The development process of our artificial

Cyclin-dependent kinases and cell division in plants: the nexus

by Vladimir Mironov, B Lieven De Veylder, A Marc Van Montagu, Dirk Inzé A - Plant Cell , 1999
"... Cell division is one of the most conspicuous features of life, and thus several elements of the control of cell division are common to both prokaryotes and eukaryotes (Amon, 1998; Leatherwood, 1998). The degree of evolutionary conservation ..."
