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.
The WI-38 cell line stemmed from earlier work by Hayflick growing human cell cultures. [2]In the early 1960s, Hayflick and his colleague Paul Moorhead at the Wistar Institute in Philadelphia, Pennsylvania discovered that when normal human cells were stored in a freezer, the cells remembered the doubling level at which they were stored and, when reconstituted, began to divide from that level to ...
In March 2020, the Cellosaurus created a page containing cell line information relevant to SARS-CoV-2 in response to the COVID-19 pandemic. [ 9 ] The Cellosaurus encyclopedia is widely recognized as an authoritative source for cell line information, providing unique identifiers [ 10 ] [ 11 ] and as source of curated information.
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.
U-937 cells are a pro-monocytic model cell line used in biomedical research. [1] They were isolated from the histiocytic lymphoma of a 37-year-old male patient in 1974. [2] Due to the relative uniformity of expanded cultures and lower maintenance requirements these cells have been since used as an important tool for studying phagocyte differentiation and different kinds of cell-to-cell ...
Proteins from both cell populations are combined and analyzed together by mass spectrometry as pairs of chemically identical peptides of different stable-isotope composition can be differentiated in a mass spectrometer owing to their mass difference. The ratio of peak intensities in the mass spectrum for such peptide pairs reflects the ...
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.
The Secretary of State maintains the style manual for the Illinois Administrative Code and Illinois Register on its website. [4] One notable feature of the Code and Register text is the use of italics (or, in less recently updated sections, all caps) to indicate that a particular set of words is quoting or closely summarizing statutory text; a reference to the relevant section of the Illinois ...
