I put this in debates because I'm sure thats what it will end up being.

Most advanced synthetic human embryos yet spark controversy
"Two teams of scientists have announced that they have grown embryo-like structures, made entirely from human stem cells, that are more advanced than any previous efforts. The synthetic embryos developed to a stage equivalent to that of natural embryos about 14 days after fertilization.
Such experiments could provide opportunities to study human embryonic development at later stages than ever before. But they also raise ethical and legal questions about the status of such ‘embryo models’ and how they should be regulated.".......
"Both teams allowed their embryo-like structures to self-assemble from human embryonic stem cells, some of which had been converted into cell types resembling the stem cells that form a placenta and the cells that form the yolk sac outside a naturally developing embryo.
The researchers say that the resulting embryo models show structures and gene transcription profiles found in human embryos between 6 and 14 days after fertilization — up to the onset of the stage called gastrulation, when the cells that will form the embryo become organized into a layer between the amniotic cavity and the yolk sac."...
