So far, human embryos produced by these techniques (known as somatic cell nuclear transfer) have not been allowed to develop into full-term human babies. The cloning of humans, of course, raises some serious ethical issues. Society will have to grapple with the issue soon, because it’s now clearly within the realm of possibility.
The basic idea behind reproductive cloning research is to be able to produce human tissues that are an exact match for the human patient from which the cloned cell was taken. Tissues produced these techniques could be used to produce skin for treating burns, or perhaps heart, or liver cells to repair a damaged organ, without fear of tissue rejection.
Do the potential medical benefits outweigh the ethical concerns associated with the creation and ultimately the sacrifice of human embryos? You decide.
