Abstract:Cancer cell lines are used to study tumor biology and as models for testing of novel anti-cancer therapeutics. The vast majority of this work has been done using established cell lines that have been cultured for decades. Upon extensive in vitro propagation, cancer cell lines acquire multiple genetic and epigenetic alterations, lose initial heterogeneity present in the parental tumor, and tend to lack tumor initiating as well as multi-lineage differentiation capacity. Consequently, it has been shown that ‘clas… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
