Whole-body gene expression atlas of an adult metazoan

Animals are integrated organ systems composed of interacting cells whose structure and function are in turn defined by their active genes. Understanding what distinguishes physiological and disease states therefore requires systemic knowledge of the gene activities that define the distinct cells that make up an animal. Towards this goal, this study reports the first single-cell resolution transcriptional atlas of a fertile multicellular organism: Caenorhabditis elegans. Overall design: We dissociated young adult N2 wild type C. elegans into single cells and analyzed them by scRNA-Seq
