Cell Lines Cultures of disaggregated tissue that can be maintained and
propagated for use in research. Cells
in the same line are typically clones. The length of time cells will survive in
culture varies. Some cell lines are
immortalized; that is, they can be maintained essentially indefinitely, for one
of a variety of reasons. Embryonic
stem cells and embryonic germ cells are immortal because they express
telomerase, one of the factors necessary for cells to propagate normally.
