An amphioxus neurula stage cell atlas supports a complex scenario for the emergence of vertebrate head mesoderm
We performed single-cell transcriptome analysis (using MARS-seq) and accessible chromatin profiling (ATAC-seq) in Branchiostoma lanceolatum embryos (21 hours post-fertilization) Overall design: Embryos were dissociated and pooled before sorting single-cells for scRNAseq.
