Therapeutic cloning treats Parkinson's in mice

Therapeutic cloning treats Parkinson's in mice
25th March 2008

Researchers in the US have claimed that therapeutic cloning has successfully treated Parkinson's disease within mice.

The team from the Memorial Sloan-Kettering Cancer Centre states that is the first time that animals have been successfully treated with their own cloned cells - and that the technique could one day be adapted to help humans.

During the therapeutic cloning trials, the nucleus of a cell was inserted into eggs with the nucleus removed.

This then developed into an embryo from which stem cells could be harvested and used in a treatment.

The mice that received neurons derived from their own clones showed significant signs of improvement.

Scientists believe that this treatment could be utilised for Parkinson's patients as it would lead to dead dopamine-producing nerve cells being replaced with new healthy ones – restoring dopamine to the brain and allowing it to work normally once more.

Parkinson's disease affects some 120,000 individuals living in the UK.
