Replicative senescence is thought to be an intrinsic mechanism for limiting the proliferative
life-span of normal somatic cells. We show here that rat Schwann cells can be expanded
indefinitely in culture while maintaining checkpoints normally lost during the immortalization
process. These findings demonstrate that senescence is not an inevitable consequence of
extended proliferation in culture.
