Cell lines - PubMed Central (PMC

Cell lines are often used in place of primary cells to study biological processes. However, care must be taken when interpreting the results as cell lines do not always accurately replicate the primary cells. In this article, we will briefly talk about advantages and disadvantages of cell lines and then discuss results using the mouse Sertoli cell. cell line. n. A cell culture that is derived from one cell or set of cells of the same type and in which under certain conditions the cells proliferate indefinitely in the laboratory.

Definition of cell line : a cell culture selected for uniformity from a cell population derived from a usually homogeneous tissue source (such as an organ) a newly established cell line derived from a human endometrial carcinoma — Biol. Abstracts Examples of cell line in a Sentenc Human Glioma Cell Lines. Cell lines, contrary to primary cultures, offer the possibility to label these by transfecting them with genes for fluorescent molecule expression, such as green fluorescent protein (GFP) or luciferase. This is of great advantage if experimenters are interested in delineating invasivity, and perhaps also importantly, tumor border and the glioma-brain interaction zone

 A cell line is a permanently established cell culture that will proliferate indefinitely given appropriate fresh medium and space.  A cell culture developed from a single cell and therefore consisting of cells with a uniform genetic make-up The term cell line refers to the propagation of culture after the first subculture. In other words, once the primary culture is sub-cultured, it becomes a cell line. A given cell line contains several cell lineages of either similar or distinct phenotypes Cell lines derived from primary cultures have a limited life span (i.e., they are finite; see below), and as they are passaged, cells with the highest growth capacity predominate, resulting in a degree of genotypic and phenotypic uniformity in the population. Cell Strain If a subpopulation of a cell line is positively selected from the culture by cloning or some other method, this cell line becomes a cell strain. A cell strain often acquires additiona

  1. Historical fetal cell lines were derived in the 1960's and 1970's from two elective abortions and have been used to create vaccines for diseases such as hepatitis A, rubella, and rabies. Abortions from which fetal cells were obtained were elective and were not done for the purpose of vaccin
  2. Continuous immortalized cell lines are comprised of a single cell type that can be serially propagated in culture either for a limited number of cell divisions (approximately thirty) or otherwise indefinitely. Cell lines of a finite life are usually diploid and maintain some degree of differentiation
  3. ated cell lines have spurred renewed interest in primary cells [1,2]

These cell lines began with a cell taken from fetal tissue, but the actual cells used for research were multiplied into many cells of the same kind A cell strain is derived either from a primary culture or a cell line by the selection or. When a primary culture is sub-cultured, it is known as secondary culture or cell line or sub-clone. The process involves removing the growth media and disassociating the adhered cells (usually enzymatically). Sub-culturing of primary cells to different divisions leads to the generation of cell lines Breast cancer cell lines are crude models of breast cancer. Despite the considerable roles played by breast cancer cell lines in deciphering the mechanisms underlying tumor initiation and evolution, cell lines are still viewed as crude models of tumors and could not capture all tumor features and heterogeneity The human epithelial cell line Caco-2 has been widely used as a model of the intestinal epithelial barrier. The Caco-2 cell line is originally derived from a colon carcinoma. However, one of its most advantageous properties is its ability to spontaneously differentiate into a monolayer of cells with

Cell Lines - an overview ScienceDirect Topic

The majority of the cells derived from vertebrates, with the exception of hematopoietic cell lines and a few others, are anchorage-dependent and have to be cultured on a suitable substrate that is specifically treated to allow cell adhesion and spreading (i.e., tissue-culture treated). However, many cell lines can also be adapted for suspension culture 'Cell-based' refers to how the influenza (flu) vaccine is made. Most inactivated flu vaccines are produced by growing flu viruses in eggs. The flu viruses used in the cell-based vaccines are grown in cultured cells of mammalian origin instead of in hens' eggs

HeLa cells are the first immortal human cell line. The cells came from a cervical cancer sample obtained from Henrietta Lack in 1951, without her knowledge or permission

Cell lines are an invaluable scientific tool. They allow us to dissect the internal workings of tissues in a controlled environment without the ethical implications of working with whole organisms. Starting with the first successful immortal cell line HeLa, the number of available cell lines has since diversified into a plethora of options The 143B-GFP human osteosarcoma cell line, with high metastatic potential, and the human MNNG/HOS-RFP human osteosarcoma cell line with low metastatic potential, both derived from the TE85 human osteosarcoma cell line, were either cotransplanted or transplanted alone in the tibia in nude mice. Upon mixed transplantation of the two differently. Cells from humans, animals, plants and micro-organisms are isolated and cultivated to develop cell lines for research studies. Many types of cell line studies have great application to the field of medical science. For instance, cell lines are used to investigate genetic mutations, cancer treatments, drug screening, aging, metabolism and vaccines

Cell Lines: Types, Nomenclature, Selection and Maintenance

Cell Lines - Cells that have been continually passaged over a long period of time and have acquired homogenous genotypic and phenotypic characteristics. Cell lines can be finite or continuous. An immortalized or continuous cell line has acquired the ability to proliferate indefinitely, either through genetic mutations or artificial modifications for human cell lines, the donor's medical history and if available, the results of tests performed on donor for the detection of adventitious agents: 3. culture history of the cell line.

Established animal cells, such as Vero, Madin Darby canine kidney (MDCK) or chicken embryo fibroblasts (CEFs), are still the main cell lines used for viral vaccine production, although new designer cells have been available for some years. These designer cell lines were specifically developed as a protocol is specific for the establishment of cell lines that constitutively express GFP-tagged proteins.

Cell lines provide an unlimited supply of material that is widely available, easy to propagate, and so form the basis for relatively high-throughput assays. This makes cell line studies on large numbers of drug combinations quite feasible. Many cell lines have now already been exhaustively characterized (8, 12, 13, 15, 16) Cell lines, continued.
