Variable cell number in nematodes [PDF]
Nature, 1999 Studies of the nematode worm Caenorhabditis elegans have led to the widely held belief that individuals of a given nematode species are characterized by a property known as eutely, in which all individuals have the same total number of cells1. This property, which is peculiar to nematodes and a few other phyla, has raised the question of whether the ...

Intraoperative cell salvage: The impact on immune cell numbers
PLOS ONE, 2023 Background Patient outcomes are influenced by many confounding factors peri-operatively, including the type of surgery, anaesthesia, transfusion, and immune competence. We have previously demonstrated (in-vitro) that compared to allogeneic blood transfusion (ABT), intraoperative cell salvage (ICS) improves immune competence.

The roles of cell size and cell number in determining ovariole number in Drosophila
Developmental Biology, 2012 All insect ovaries are composed of functional units called ovarioles, which contain sequentially developing egg chambers. The number of ovarioles varies between and within species. Ovariole number is an important determinant of fecundity and thus affects individual fitness.

Effects of teicoplanin on cell number of cultured cell lines [PDF]
Interdisciplinary Toxicology, 2015 Abstract Teicoplanin is a glycopeptide antibiotic with a wide variation in human serum half-life. It is also a valuable alternative of vancomycin. There is however no study on its effect on cultured cells. The aim of the present study was to test the effect of teicoplanin on cultured cell lines CHO, Jurkat E6.1 and MCF-7.

Inflating Cell Numbers by Wnt [PDF]
Molecular Cell, 2002 One of the prominent biological phenomena controlled by Wnt signaling is the expansion of cells with predefined fates. In the November 27, 2002, issue of Cell, Rosenfeld and colleagues describe an example of Wnt-controlled proliferation during genesis of the cardiac outflow tract and the pituitary gland.

A cell number counting factor alters cell metabolism [PDF]
Communicative & Integrative Biology, 2009 It is still not clear how organisms regulate the size of appendages or organs during development. During development, Dictyostelium discoideum cells form groups of approximately 2 x 10(4) cells. The cells secrete a protein complex called counting factor (CF) that allows them to sense the local cell density.

Classification of arrangements by the number of their cells [PDF]
Discrete & Computational Geometry, 1993 Associated with an arrangement \(\mathcal A\) of \(n\) lines in the real projective plane \(\mathcal P\) is the 2-dimensional cell complex in \(\mathcal P\) consisting of the vertices, edges and cells of \(\mathcal A\). The paper characterizes all pairs \((n,f)\) of integers for which there is an arrangement in \(\mathcal P\) with exactly \(n\) lines ...

Synthetic cells by the numbers
iScienceCan we build a living cell from non-living molecular components? This foundational question drives the field of synthetic cell engineering, having already reconstituted key cellular processes within synthetic environments, and now advancing toward their integration into systems of increasing complexity.
