According to nomenclature, cell names in embryonic lineages are written without a period between the blast cell name and ant/post or left/right divisions (e.g., AB apa), while in postembryonic lineages a period is introduced between blast cell name and ant/post or left/right divisions (e.g., Z1.pap)

Cell lineage diagram c elegans

The embryonic cell lineage of Caenorhabditis elegans has been traced from zygote to newly hatched larva, with the result that the entire cell lineage of this organism is now known. During embryogenesis 671 cells are generated; in the hermaphrodite 113 of these (in the male 111) undergo programmed death and the remainder either differentiate ...

Sep 20, 2019 · Single-cell RNA-seq of C. elegans embryos. We sequenced the transcriptomes of single cells from C. elegans embryos with the 10x Genomics platform. We assayed loosely synchronized embryos enriched for pre-terminal cells as well as embryos that had been allowed to develop for ~300, ~400, and ~500 minutes after the first cleavage of the fertilized egg.

The C. elegans embryonic cell lineage with the 66 gastrulating cells each represented in colors here and in (B,D,E) corresponding to the six traditionally-recognized cell lineages. Each vertical line represents a cell, with its length indicating its cell cycle period.

The nematode worm Caenorhabditis elegans has only 558 cells at hatching. Despite its limited cell number, however, C. elegans contains a wide diversity of cell types and a complex anatomy. Its cell lineage is invariant—every individual C. elegans animal is produced by the exact same sequence of cell divisions—and this lineage has been fully mapped. . Together, these features make it an ...

The complete cellular anatomy (including the complete wiring diagram of the nervous system) and the complete cell lineage of C. elegans are known, allowing mutant animals to be studied at the level of single cells and even single synapses. Genes defined by mutations can be rapidly cloned and analyzed.

Fig. 1. Partial C. elegans lineage, diagram and images showing stages of embryogenesis. A: The zygote undergoes a set of asymmetric clea-vages to generate the six founder cells, AB, MS, E, C, D, and P 4 (Sulston et al., 1983). Anterior cells are to the left. B: Diagram of early and mid-

We identify 502 terminal and preterminal cell types, mapping most single-cell transcriptomes to their exact position in C. elegans' invariant lineage. Using these annotations, we find that (i) the correlation between a cell's lineage and its transcriptome increases from middle to late gastrulation, then falls substantially as cells in the ...

As a quick glance at the diagram shows, C. elegans neurons are largely non-clonally derived from many different lineages (red lines in Figure 2 ). Some lineage sub-branches give rise exclusively to neurons, yet in some cases neuronal vs. non-neuronal choices are made only very late in the lineage (a few examples are shaded in grey in Figure 2 ).

Caenorhabditis elegans is uniquely suited to the analysis of cell lineage patterns.C. elegans has a small number of somatic cells whose position and morphology are almost invariant from animal to animal. Because C. elegans is virtually transparent, cells can be identified in live animals using a simple bright-field microscopy technique, Nomarski differential interference contrast (DIC), or by ...

cell lineage of C. elegans (4). Together, these studies deﬁned the ﬁrst, and to date only, completely known cell lineage of an animal (Figure 3). The C. elegans cell lineage, which is essentially invariant among individuals, presents many of the problems of developmental biology at the level of reso-lution of single cells.
