Untwisting the Caenorhabditis elegans embryo
The nematode Caenorhabditis elegans possesses a simple embryonic nervous system with few enough neurons that the growth of each cell could be followed to provide a systems-level view of development. However, studies of single cell development have largely been conducted in fixed or pre-twitching live embryos, because of technical difficulties associated with embryo movement in late embryogenesi...
متن کاملDevelopmental robustness in the Caenorhabditis elegans embryo.
Developmental robustness is the ability of an embryo to develop normally despite many sources of variation, from differences in the environment to stochastic cell-to-cell differences in gene expression. The nematode Caenorhabditis elegans exhibits an additional level of robustness: Unlike most other animals, the embryonic pattern of cell divisions is nearly identical from animal to animal. The ...
متن کاملNucleologenesis in the Caenorhabditis elegans Embryo
In the Caenorhabditis elegans nematode, the oocyte nucleolus disappears prior to fertilization. We have now investigated the re-formation of the nucleolus in the early embryo of this model organism by immunostaining for fibrillarin and DAO-5, a putative NOLC1/Nopp140 homolog involved in ribosome assembly. We find that labeled nucleoli first appear in somatic cells at around the 8-cell stage, at...
متن کاملObjective measurement of spindle orientation in early Caenorhabditis elegans embryo.
The spindle orientation is a crucial piece of information to understand the development of embryo. The spindle forms during cell division and the cell divides along the spindle axis. Spindle orientation was measured in many different mutant embryos of Caenrohabditis elegans. However, the objectivity and the productivity of these measurements were low because these measurements were made manuall...
