Spatial transcriptomics of the nematode Caenorhabditis elegans using RNA tomography

Abstract

Summary: RNA tomography or tomo-seq combines mRNA sequencing and cryo-sectioning to spatially resolve gene expression. We have adapted this method for the nematode Caenorhabditis elegans to generate anteroposterior gene expression maps at near-cellular resolution. Here, we provide a detailed overview of the method and present two approaches: one that includes RNA isolation for maximum sensitivity and one that is suitable for partial automatization and is therefore less time-consuming.For complete details on the use and execution of this protocol, please refer to Ebbing et al. (2018).
