Human stem cells could be implanted in an early pig embryo, making a chimera with human organs suitable for transplant.

There has been much handwringing about the news that scientists injected human stem cells into pig embryos, creating a mostly - pig - but - a-little-bit-human chimera.

Then they would inject human stem cells into the pig embryo in hopes that the human stem cells would bridge the gaps of the missing pancreas gene and form a human pancreas.
