There are scientists in California that have made embryos that are clones of two different men. The embryos were made using ordinary skin cells. The next big thing they are waiting for is to make a human embryonic stem cell line from cloned human embryos. Scientists think that stem cells from cloned embryos could be used to study diseases, screen drugs, and make transplant materials to treat conditions, such as diabetes and Parkinson’s disease.
The problems with cloning human embryos include, creating human lives in a laboratory purposely to destroy them to benefit and help other people, there are health risks involved in the process, and exploiting the women who are asked to provide eggs.
The cloning process works by injecting DNA from a person into an egg. The egg would grow into an embryo in about five days. Then, stem cells would be extracted from the embryo.
