And whereas you saw iron mixed with miry clay, they shall mingle themselves with the seed of men: but they shall not join one to another, even as iron is not mixed with clay.
Scientists grow human organs for transplant inside pigs
They have injected human stem cells into pig embryos to produce human-pig embryos known as chimeras.
The embryos are part of research aimed at overcoming the worldwide shortage of transplant organs.
The team from University of California, Davis says they should look and behave like normal pigs except that one organ will be composed of human cells.
The human-pig chimeric embryos are being allowed to develop in the sows for 28 days before the pregnancies are terminated and the tissue removed for analysis.
