Single-cell data released

See the corresponding page for details on how to explore the dataset. See our preprint for the full set of analyses.


Differential gene expression defines individual neuron types and determines how each contributes to circuit physiology and responds to injury and disease. The C. elegans Neuronal Gene Expression Map & Network (CeNGEN) is working to establish a comprehensive gene expression atlas of an entire nervous system at single-neuron resolution.

Two approaches are being used:

1) single-cell RNA-Sequencing, which allows the identification of each neuronal class;

2) deep bulk RNA sequencing of sorted neurons from each class enables full characterization of its transcriptome and of non-coding RNAs.
