Single cell RNA-seq of in vitro cultured human embryos. Single cell RNA-seq of in vitro cultured human embryos

Human embryogenesis is characterised by a series of coordinated cell fate specification events. Upon implantation on day 7, the three cell lineages forming the human blastocyst undergo major morphogenetic and transcriptomic changes. Using single-cell RNA sequencing, we reconstruct the molecular events driving post-implantation development of the human embryo at day 9 and 11. Our study provides the first molecular map of gene expression patterns in early post-implantation human embryos, unveiling how signalling interactions between embryonic and extra-embryonic tissues drive human embryogenesis.
