Single-cell RNA-seq of the 16-cell stage Ciona embryo. Single-cell RNA-seq of the 16-cell stage Ciona embryo

Ciona develops according to a stereotyped or invariant lineage. This allowed us to collect precisely defined replicates of all eight blastomeres of the right half of the embryo at the 16-cell stage of Ciona. We manually dissected each embryo, collecting and identifying each cell before library preparation and single-cell RNA-seq to give us a data set of 8 blastomeres x 4 embryos (32 cells). We sequenced these on MiSeq and HiSeq 2500. A fifth embryo was only sequenced on MiSeq and excluded from subsequent analysis.
