Spatio-temporal mRNA tracking in the early zebrafish embryo


ABSTRACT: We performed spatially resolved transcriptomics with sub-single-cell resolution in zebrafish embryos at the one-cell stage, which allowed us to identify a class of mRNAs that is specifically localized at an extraembryonic position in the yolk sac, the vegetal pole. The 3’ UTRs of these localized genes are enriched in specific sequence motifs. Comparison to two frog species revealed relatively low conservation of localized genes, but high conservation of sequence motifs. In vivo RNA labeling followed by scRNA-seq revealed that a large number of the localized transcripts are specifically transported to the primordial germ cells.
