ABSTRACT
The use of human embryos for studying the early implantation processes and trophoblast is restricted by ethical concerns. The development of models mimicking the peri-implantation embryos is critical for understanding the physiology of human embryos and many pathophysiological disorders including recurrent implantation failure and miscarriage. Three-dimensional (3D) models of trophoblastic spheroids have been successfully derived from human embryonic stem cells (hESC). Simultaneous activation of the BMP pathway and blockage of the Activin/Nodal pathway favor the differentiation of hESC into trophoblast. Here we describe a 3D trophectoderm differentiation protocol with the use of BAP (BMP4, A83-01, and PD173074) to generate hESC-derived trophectoderm spheroids (BAP-EB). BAP-EB is highly reproducible and exhibits morphological and transcriptomic similarities to human early blastocysts.
