ABSTRACT
In situ hybridization is a powerful and precise tool for revealing cell- and tissue-specific gene expression and a critical approach to validating single-cell RNA-seq (scRNA-seq). However, applying it to highly fragile animals such as ctenophores is challenging. Here, we present an in situ hybridization protocol for adult Pleurobrachia bachei (Cydippida)-a notable reference species representing the earliest-branching metazoan lineage, Ctenophora, sister to the rest of Metazoa. We provided expression patterns for several markers of cell phenotypes, as illustrated examples. The list includes predicted small secretory molecules/neuropeptides, WntX, genes encoding RNA-binding proteins (Musashi, Elav, Dicer, Argonaut), Neuroglobin, and selected transcription factors such as BarX. Both cell- and organ-specific expression of these genes further support the convergent evolution of many ctenophore innovations, which are remarkably distinct from tissue and organ specification in other basal metazoan lineages.
