Primary cell culture is the ex vivo culture of cells freshly obtained from a multicellular organism, as opposed to the culture of immortalized cell lines.In general, primary cell cultures are considered more representative of in vivo tissues than cell lines, and this is recognized legally in some countries such as the UK (Human Tissue Act 2004). [1]
Besides the culture of well-established immortalised cell lines, cells from primary explants of a plethora of organisms can be cultured for a limited period of time before senescence occurs (see Hayflick's limit). Cultured primary cells have been extensively used in research, as is the case of fish keratocytes in cell migration studies. [88 ...
Immortalized cell lines can be generated from cells isolated from tumors, or mutations can be introduced to make the cells immortal. [1] A stem cell line is also distinct from primary cells. Primary cells are cells that have been isolated and then used immediately. Primary cells cannot divide indefinitely and thus cannot be cultured for long ...
An immortalised cell line is a population of cells from a multicellular organism that would normally ... performing an analysis on primary cells from multiple tissue ...
These cells may be cells isolated from a donor organism (primary cells) or an immortalised cell line. The cells are bathed in a culture medium, which contains essential nutrients and energy sources necessary for the cells' survival. [8] Thus, in its broader sense, "tissue culture" is often used interchangeably with "cell culture".
The story of how the HeLa cell line came to be was also the subject of a 2010 episode of the podcast Radiolab. [69] HeLa cells were the subject of a 2010 book by Rebecca Skloot, The Immortal Life of Henrietta Lacks, investigating the historical context of the cell line and how the Lacks family was involved in its use.
