The blastocyst is the mammalian pre-implantation embryo. It consists of an outer epithelial layer of trophoblast cells surrounding a fluid-filled cavity sheltering the embryonic and primitive endoderm cells. From the mouse blastocyst, trophoblast and embryonic stem cells lines can be derived, which have the capacity to indefinitely self-renew in vitro while maintaining the ability to differentiate into all placental and embryonic lineages, respectively. Here, I describe how to form blastoids (synthetic blastocysts) formed from trophoblast and embryonic stem cells. Blastoids morphologically and transcriptionally resemble E3.5 blastocysts, and can implant in utero. Although not recapitulating the full complexity of the embryo, blastoids are simplified models allowing new approaches in embryology. Contrary to blastocysts, blastoids can be generated in large numbers, which allows to harvest material for in-depth assays (e.g. genomics, biochemistry), run high-throughput screens, and to rapidly perform compartment-specific genetic modifications. As such, blastoids are powerful tools to study the principles of stem cell self-organization and embryonic development.
Note: Minor errors in this protocol were corrected on the 18th of May 2018.
