New types of cell line cells are established after sufficient passaging of a primary culture to establish a stable and homogenous population that qualifies as a line (typically 1-20 passages), or following some spontaneous or experimental modification that confers novel characteristics to an existing line. A cell line cell typically has mutations of five or more genes compared to the original cell that derives the cell line cell. Some gene mutations may turn on some oncogenes. Cell line cells can be in active culture, stored in a quiescent state for future use (e.g. frozen in liquid nitrogen), or applied in experimental procedures.
