Efficiency vs. number of cells in cell formation

2018 Third International Conference on Electrical and Biomedical Engineering, Clean Energy and Green Computing (EBECEGC), 2018
The effects of some of the physical, technological, or organizational constraints will force the system designer to specify the number of cells in advance. Different layouts and alternative optimal solutions will give the designer more flexibility to avoid some of these constraints. In this paper a sensitive analysis of the impact of number of cells on

Neural stem cells and regulation of cell number

Progress in Neurobiology, 2002
Normal CNS development involves the sequential differentiation of multipotent stem cells. Alteration of the numbers of stem cells, their self-renewal ability, or their proliferative capacity will have major effects on the appropriate development of the nervous system.

T Cell Development by the Numbers

Trends in Immunology, 2017
T cells are continually generated in the thymus in a highly dynamic process comprising discrete steps of lineage commitment, T cell receptor (TCR) gene rearrangement, and selection. These steps are linked to distinct rates of proliferation, survival, and cell death, but a quantitative picture of T cell development is only beginning to emerge.

Regulation of cell number in Drosopfiila

Nature, 1994
During animal development, different parts grow independently (such as the left and right hands) but they stop growing when they reach the correct size. In most insects, growth of the epidermis is so controlled that, at each moult, there is a precise and proportionate increase in cell number.

Chromosome Numbers in Cancer Cells

Nature, 1947
DURING an investigation on the variation of the chromosome system in human cancer of the uterus, we were able to observe frequently (in six epitheliomas of the uterus portio) a mitotic figure with a peculiar aspect of the chromosomes. In such cell divisions (which appear mixed with normal, heteroploid and polyploid ones) 24 chromosomes are present ...

Estimation of the Number of Cells via the Number of Randomly Occupied Cells

Journal of Mathematical Sciences, 2016
Summary: We consider a scheme of series where the growth of the distribution support is asymptotically proportional to the growth of the sample size. It is assumed that the values of sample elements are inaccessible, whereas the number of different elements is known.

Number of Chromosomes in the Human Cell

Nature, 1960
CURRENT work with human chromosomes in many laboratories has resulted in the publication of numerous photographs of chromosomes of human cells both normal and abnormal. Almost all these have been obtained from cells which are selected at least to the extent that they are cells capable of undergoing mitosis one or more times in vitro.

Plasticity of Fat Cell Number

The Journal of Nutrition, 1984
Rats fed ad libitum (group 1) had little change in fat cell number in epididymal depots from 6 to 27 months of age, but a marked increase in fat cell number in perirenal depots between 6 and 18 months. Food restriction of rats to 60% of group 1 from 6 weeks of age on (group 2) reduced fat cell number in both depots throughout life and prevented an ...

Uniqueness and the Cell Reynolds Number

SIAM Journal on Numerical Analysis, 1980
Using some results from the theory of M-functions, we show how uniqueness and multiplicity of solutions for three finite-difference approximations of the steady Burgers equation are related to the cell Reynolds number.

Regulation of cell attachment and cell number by fibronectin and laminin

Journal of Cellular Physiology, 1986
AbstractWe have examined the effect of laminin and fibronectin on the attachment and growth on type IV collagen of a line of mouse epithelial cells and a strain of adult human fibroblasts. Laminin stimulated attachment of the epidermal cells and fibronectin stimulated fibroblast attachment.
