Form of the worm:: genetics of epidermal morphogenesis in C-elegans

The development of the epidermis of the nematode worm Caenorhabditis elegans illustrates many common processes of epithelial morphogenesis. In the worm, these morphogenetic movements have been described with single-cell resolution, and the roles of individual cells have been probed in laser killing experiments. Genetic dissection is yielding insights into the molecular mechanisms of these complex morphogenetic processes.
