Summary:
We performed spatial transcriptome analysis on cryosections of gastrulating embryos from E6.5 to E7.5 by low-input RNA sequencing (Geo-seq). Careful spatial transcriptomic analysis revealed that the lncRNA Evx1as plays a transient spatiotemporal role in regulating embryonic patterning during gastrulation, yet is dispensable for overall development and survival. Altogether, these results suggest that many lncRNAs are generally dispensable for normal development and survival, but may be selectively required in a particular context in vivo.Overall design:
