9 Expression Patterns

• Primary Identifier: Expr7777
• Remark: Clone: pUL#IAH9H8
• Pattern: No expression

• Primary Identifier: Expr4000
• Remark: In the related nematode, C. briggsae, in situ hybridization with a Cb-med-1 probe reveals gonadal as well as embryonic signal in EMS.
• Pattern: Embryonic med transcripts accumulate in the EMS nucleus at the 4-cell stage, become cytoplasmic in MS and E, and are undetectable thereafter. Signal was also observed in the gonads of all adults, with 68% (174/257) showing very strong staining, while very little or no gonadal signal was observed using sense probes. Authors did not detect significant levels of med transcripts in very early embryos or late oocytes.
• Subcellular Localization: Embryonic med transcripts accumulate in the EMS nucleus at the 4-cell stage, become cytoplasmic in MS and E.

• Pattern: Single cell embryonic expression. Only cell types with an expression fraction of greater 0.2 of the maximum expressed fraction are labeled (Full data can be downloaded from http://caltech.wormbase.org/pub/wormbase/datasets-published/packer2019/). The colors represent the broad cell class to which the cell type has been assigned. The size of the point is proportional to the log2 of the numbers of cells in the dataset of that cell type.

• Primary Identifier: Expr10360
• Pattern: Inferred expression. EPIC dataset. http://epic.gs.washington.edu/ Large-scale cellular resolution compendium of gene expression dynamics throughout development. This reporter was inferred to be expressing in this cell or one of its embryonic progenitor cells as described below. To generate a compact description of which cells express a particular reporter irrespective of time, the authors defined a metric "peak expression" for each of the 671 terminal ("leaf") cells born during embryogenesis. For each of these cells, the peak expression is the maximal reporter intensity observed in that cell or any of its ancestors; this has the effect of transposing earlier expression forward in time to the terminal set of cells. This metric allows straightforward comparisons of genes' cellular and lineal expression overlap, even when the expression occurs with different timing and despite differences in the precise time point that curation ended in different movies, at the cost of ignoring the temporal dynamics of expression, a topic that requires separate treatment. For simplicity, the authors use the term "expressing cells" to mean the number of leaf cells (of 671) with peak expression greater than background (2000 intensity units) and at least 10% of the maximum expression in that embryo.
