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. The cells can therefore be grown for prolonged periods in vitro. The mutations required for immortality can occur ...
Early research (Bathurst and Jarrett, 1988) [13] found that cellular confinement reinforced gravel bases are "equivalent to about twice the thickness of unreinforced gravel bases" and that geocells performed better than single sheet reinforcement schemes (geotextiles and geogrids) and were more effective in reducing lateral spreading of infill under loading than conventional reinforced bases.
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 ...
SH-SY5Y is a human derived cell line used in scientific research. The original cell line, called SK-N-SH, from which it was subcloned was isolated from a bone marrow biopsy taken from a four-year-old female with neuroblastoma. SH-SY5Y cells are often used as in vitro models of neuronal function and
A typical volume of Bell System Practices from the 1970s. The Bell System Practices (BSPs) is a compilation of technical publications which describes the best methods of engineering, constructing, installing, and maintaining the telephone plant of the Bell System under direction of AT&T and Bell Telephone Laboratories.
