An immortalised cell line is a population of cells from a multicellular organism that would normally not proliferate indefinitely but, due to mutation, have evaded normal cellular senescence and instead can keep undergoing division. The cells can therefore be grown for prolonged periods in vitro. The mutations required for immortality can occur ...
There are two principal ways in which a cell line can become contaminated: cell cultures are often exchanged between research groups; if, during handling, a sample is contaminated and then passed on, subsequent exchanges of cells will lead to the contaminating population being established, although parts of the supposed cell line are still genuine.
In cellular biology, stable cells are cells that multiply only when needed. They spend most of the time in the quiescent G 0 phase of the cell cycle but can be stimulated to enter the cell cycle when needed. Examples include the liver, the proximal tubules of the kidney and endocrine glands.
A cellular automaton consists of a regular grid of cells, each in one of a finite number of states, such as on and off (in contrast to a coupled map lattice). The grid can be in any finite number of dimensions. For each cell, a set of cells called its neighborhood is defined relative to the specified cell.
Children as young as 11 are confined alone to cells the size of parking spaces up to 23 hours a day at a juvenile detention center in Southern Illinois, according to a lawsuit filed by ACLU of ...
Land subsidence outside of Ruler Foods in Belleville, Ill., where an old mine below the store caused the land surrounding the building to sink into the ground on Sept. 26, 2023.
Disease and virology studies can use permanent cells to maintain cell count and accurately quantify the effects of vaccines. [1] Some embryology studies also use permanent cells to avoid harvesting embryonic cells from pregnant animals; since the cells are permanent, they may be harvested at a later age when an animal is fully developed. [4]
