Summary | Balancing proliferation and differentiation is critical for development and tissue self-renewal. In the germ line, the self-renewal versus differentiation decision depends on many conserved RNA-binding proteins. However, how precisely these proteins control the cell cycle status has remained elusive. Using C. elegans as a model, we find that translational regulation of cyclin E/CDK-2 activity determines whether germ cells self-renew or differentiate. Interestingly, this regulation is also critical for germ line totipotency, providing a paradigm for the possible origin of human teratocarcinomas. |
