Abstract

In a recent issue of Nature, Kagawa et al. reported a highly efficient and robust protocol for generating human blastoids from naive human pluripotent stem cells. The blastoids resemble human blastocysts, follow the sequential lineage specification of blastocyst development, and can attach to endometrial cells with the polar trophectoderm to model implantation.
