ABSTRACTTo improve our understanding of pattern formation during development and disease we heavily rely on the identification of novel regulators and pathways. While RNA sequencing yields genome-wide expression data that suit this purpose, it lacks spatial resolution. Such spatial resolution can be obtained by microscopy-based methods like in situ hybridization, but these fail to provide information on more than a few genes at a time. Here, we describe tomo-seq, a technique that combines the advantages of the above-mentioned approaches and provides genome-wide expression data with spatial information. The tomo-seq technique is based on cryosectioning of an embryo or tissue of interest and performing RNA-seq on individual sections. Using this method, we have generated genome-wide transcriptomics with high spatial resolution of the whole zebrafish embryo at various stages of development (Junker et al., 2014) and of adult zebrafish hearts after injury.
