Morphogenesis of the C. elegans hermaphrodite uterus.
We have undertaken electron micrographic reconstruction of the Caenorhabditis elegans hermaphrodite uterus and determined the correspondence between cells defined by their lineage history and differentiated cell types. In this organ, many cells do not move during morphogenesis and the cell lineage may function to put cells where they are needed. Differentiated uterine cell types include the tor...
متن کاملReciprocal EGF signaling back to the uterus from the induced C. elegans vulva coordinates morphogenesis of epithelia
BACKGROUND Reciprocal signaling between distinct tissues is a general feature of organogenesis. Despite the identification of developmental processes in which coordination requires reciprocal signaling, little is known regarding the underlying molecular details. Here, we use the development of the uterine-vulval connection in the nematode Caenorhabditis elegans as a model system to study recipr...
متن کاملImaging embryonic morphogenesis in C. elegans.
The Caenorhabditis elegans embryo is well suited to morphogenetic analysis via modern microscopy, due to its short generation time, transparency, invariant lineage, and the ability to generate transgenic embryos expressing various fluorescent proteins. This chapter provides an overview of microscopy techniques for imaging embryonic morphogenesis, including making agar mounts, capturing four-dim...
متن کاملThe cytoskeleton and epidermal morphogenesis in C. elegans.
During Caenorhabditis elegans development, the process of epidermal elongation converts the bean-shaped embryo into the long thin shape of the larval worm. Epidermal elongation results from changes in the shape of epidermal cells, which in turn result from changes in the epidermal cytoskeleton, the extracellular matrix, and in cell-matrix adhesion junctions. Here, we review the roles of cytoske...
متن کاملxo1-1 acts as an early switch in the C. elegans male/hermaphrodite decision
xol-1 is the earliest-acting gene in the known hierarchy that controls C. elegans sex determination and dosage compensation. We show that the primary sex-determining signal (the X/A ratio) directs the choice of sexual fate by regulating xol-1 transcript levels: high xol-1 expression during gastrulation triggers male development, whereas low expression at that time permits hermaphrodite developm...
