| Abstrakt: | Whole-mount in situ hybridization (WISH) is an extremely useful technique for visualizing specific mRNA targets and solving many biological questions. In planarians, this method is really valuable, for example, for determining gene expression profiles during whole-body regeneration and analyzing the effects of silencing any gene to determine their functions. In this chapter, we present in detail the WISH protocol routinely used in our lab, using a digoxigenin-labelled RNA probe and developing with NBT-BCIP. This protocol is basically that already described in Currie et al. (EvoDevo 7:7, 2016), which put together several modifications developed from several laboratories in recent years that improved the original protocol developed in the laboratory of Kiyokazu Agata in 1997. Although this protocol, or slight modifications of it, is the most common protocol in the planarian field for NBT-BCIP WISH, our results show that key steps such as the use and time of NAC treatment to remove the mucus need to be taken into account depending on the nature of the gene analyzed, especially for the epidermal markers.
