For the first time cloning human embryos

US scientists claim they have used cloning techniques to create human embryos, an extremely important achievement for medicine.

Shoukhrat Mitalipov, a researcher at Oregon Health and Science University in the US, and colleagues have used cloning techniques to create human embryos, the BBC reported.

The technique that the team used - the stem cell nuclear transfer (somatic cell) - was the same technique that created the first cloned sheep in 1996. They took skin cells from the body. an adult then puts the nucleus of the cell inside the egg they have removed. They then used electricity to stimulate eggs to develop into embryos.

'We took embryonic stem cells and examined them. The results showed that these stem cells could turn into all kinds of cells - like nerve cells, liver cells and heart cells , "Mitalipov said.

Stem cells, or germ cells, are capable of developing into other types of cells. With that ability, stem cells are one of the greatest medical hopes. It can help people recover damage to the heart or spinal cord. Currently many research facilities are testing therapies to restore sight to the blind by stem cells.

Scientists now take human embryonic stem cells. However, a part of scholars and public opinion opposes the exploitation of stem cells from embryos because it is an immoral act. So, for years, scientists have been trying to find solutions to create other germ cell supplies to replace embryos.
