The Fertilization and Embryology Authority of the United Kingdom has approved embryo research on animal and human hybrids. The purpose is to get them to assist in stem cell research for diseases such as Alzheimer's or Parkinson's.

There are two groups of researchers from King's College and the University of Newcastle upon which the above decision, they hope that their proposals will be accepted and be granted a license for this type of research.

The hybrid embryos are formed from the introduction of DNA into human eggs from animals that have been previously extracted the nucleus. According to scientists, the result is 99% human.

The goal is to get them later stem cells that can be used in medical research. This is a necessary process, according to the researchers, given the current shortage of human eggs available for research.
