C. elegans cell cycle analysis.

Caenorhabditis elegans is an important system for the study of cell cycle regulation in the context of animal development. One of the most powerful features of C. elegans is the invariant cell lineage in which somatic cells initiate cell division at specific times within the developmental program. The cell lineage is fully known and provides the foundation for the analysis of cell cycle progression at single-cell resolution in a multicellular organism. In this chapter, we describe the different types of cell cycles observed in C. elegans, and provide methods and reagents for the analysis of cell cycle progression as well as specific cell cycle phases. We also provide strategies for the analysis and proper interpretation of cell cycle and checkpoint mutants.
