Little pig, little pig, let me come in
Scientists in the United States are trying to grow human organs 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.
