Figure 1 (A) Monochorionic dizygotic blastocyst formation in vitro is distinctly recognized by the complete amalgamation of fused TE layers, creating a shared blastcoelic cavity and separate fraternal inner cell masses (objective magnification: ×200). (B) Blastocysts grown in group culture often exhibit closely opposed hatching TE, but rarely experience cellular fusion (objective magnification: ×100).
