The angular distribution of directional changes of guided 3T3 cells
نویسنده
چکیده
This paper reports that the angular distribution of directional change of 3T3 cells which followed guiding lines on a substrate and left the guidance at various angles shows a peculiar preference for angles between 30 degrees and 60 degrees. Regarding the phenomenon of cellular guidance itself, 3T3 cells faced with a choice between guiding lines toward different directions seem to explore various options before following one. This observation suggests that the outcome of a probing action and not substrate properties alone can explain the guidance behavior of 3T3 cells.

Two optimal algorithms for finding bi-directional shortest path design problem in a block layout
In this paper, Shortest Path Design Problem (SPDP) in which the path is incident to all cells is considered. The bi-directional path is one of the known types of configuration of networks for Automated Guided Vehi-cles (AGV).To solve this problem, two algorithms are developed. For each algorithm an Integer Linear Pro-gramming (ILP) is determined. The objective functions of both algorithms are t...

Backgrounds: A straight-forward way to identify whether a drug or environmental chemical can be harmful to unborn baby is to evaluate its effect on laboratory animals. All invivo methods need large number of animal and are therefore time consuming and expensive. However, the thousands of chemicals in need of testing, to reduce the spending of live animals, an assortment of in vitro assays has ...

Using a new technique to visualize the tracks of moving 3T3 cells and combining it with the visualization of actin-containing microfilament bundles by indirect immunofluorescence (Lazarides, E. and K. Weber. 1974, Proc. Natl. Acad. Sci. U.S.A. 71:2268-2272), I present experiments which suggest that: (a) 30-40% of the pairs of daughter 3T3 mouse fibroblasts in noncloned cultures have mirror sym...
متن کاملElectric field-directed fibroblast locomotion involves cell surface molecular reorganization and is calcium independent
Directional cellular locomotion is thought to involve localized intracellular calcium changes and the lateral transport of cell surface molecules. We have examined the roles of both calcium and cell surface glycoprotein redistribution in the directional migration of two murine fibroblastic cell lines, NIH 3T3 and SV101. These cell types exhibit persistent, cathode directed motility when exposed...
