Human-chicken hybrids in the lab

Nature reports on the creation of human-chicken hybrids using “embryo-like structures” in order to study human embryonic “organizer cells.”

The ethical line is at destroying the embryo to harvest the stem cells. Could these “structures” have been created with ethical induced non-destructive stem cells?
I’m not sure that the “embryo-like” structures are or ever had the capacity to become human organisms, but it is worrying that the implication is that they were. It doesn’t appear that there was ever a placenta or the possibility of one. However, the “structures” developed a primitive streak and notochord – the earliest neural and skeletal structures – and other apparently human cell lines

, in an organized manner.

How significant are the primitive streak and notochord? Are these deliberately created stunted human organisms or simply cell lines and isolated organ systems grown in the lab? What are the ethical limits for creating huma-animal hybrids?
Scientists must respect the dignity of every human being, at every stage of life and development. That is not possible if beginning by destroying a human embryo.
