Furthermore, NTERA-2 cells differentiate into nonneural epithelial cells when treated with bone morphogenic protein-2 (BMP-2), whereas 27X-1 cells, another human ECC line, differentiate into extraembryonic endoderm when exposed to BMP-2 or RA [68, 69].
Most of the developed protocols for the in vitro differentiation of pluripotent stem cells are based on the knowledge of the molecular mechanisms that regulate the commitment and differentiation of early embryonic and extraembryonic cells during development.

The cells can develop into all fetal cell types, but not into extraembryonic tissues, such as the placenta.
Therefore, the mature placental barrier will comprise the following components: syncytiotrophoblast, cytotrophoblast, extraembryonic mesoderm, and the endothelial lining of the chorionic vessels (Sadler; Huppertz; Prieto Gomez et al., 2011; Roa et al.; Carlson).
Upon reaching an adequate stage, the embryos were extracted in PBS/DEPC (phosphate-buffered saline/diethylpyrocarbonate) to remove the extraembryonic membranes and were fixed in 4% paraformaldehyde (PFA) overnight at 4[degrees]C (6-12 hours).
