Genetic Dissection of Caenorhabditis elegans Embryogenesis Using RNA Interference and Flow Cytometry

Study of Caenorhabditis elegans embryonic development has been useful to dissect the molecular mechanisms controlling cell proliferation, cell polarization, cell differentiation, and morphogenic events also involved in embryogenesis in human (1, 2). The strength of this organism for developmental research consists in its amenability to large-scale genetic screening, its simple morphology, and transparency enabling study of developmental processes at a single cell level. Large-scale genetic screening targeting embryonic development in C. elegans is usually poorly sensitive and non-quantitative (3, 4).
