Cancer cell lines are originally derived from patient tumors, but acquire the ability to proliferate within in vitro cell cultures. As a result of in vitro manipulation, cell lines that have been traditionally used in cancer research undergo genetic transformations that are not restored when cells are allowed to grow in vivo.
