cell line obsolete_cell line true A split of HeLa cells in active culture, or stored in frozen aliquots. Populations of HEK 293 cells used in experiments such as those documented in Changes in ultrastructure and endogenous ionic channels activity during culture of HEK 293 cell line. Eur J Pharmacol. 2007 Jul 12;567(1-2):10-8. PMID: 17482592. A secondary cultured cell population that represents a genetically stable and homogenous population of cultured cells that shares a common propagation history (ie has been successively passaged together in culture). He, Tong-Chuan, et al. Identification of c-MYC as a target of the APC pathway. Science 281.5382 (1998): 1509-1512. - To evaluate the transcriptional effects of APC, we studied a human colorectal cancer cell line (HT29-APC) containing a zinc-inducible APC gene and a control cell line (HT29–β-Gal) containing an analogous inducible lacZ gene. Note that common usage in the literature is often of the form a human colorectal cancer cell line, as seen above. But such references to studies in a line refer to the fact that discrete populations of cells that are input into culturing or experiments, not an entire lineage of cells. It is these discrete populations that we refer to as 'cell lines'. cell line sample obsolete_cell line OBI-CLO Alignment Working Group (Spring 2013) PERSON:Matthew Brush Obsolete Class metadata complete term imported
