Scientists in Britain have recreated Down's syndrome in mice in order to study the disease and develop new a treatment for the genetic disorder. They have injected the human chromosome '21' in mice embryos causing the mice to have Down's syndrome. Human babies who have Down's syndrome inherit three copies of chromosome 21, instead of two. With Down's syndrome babies being born one in every 800, this will certainly make a impact on the world.
LONDON, SEPTEMBER 23: Scientists have transplanted human chromosome 21 in mice in a breakthrough that could yield key insights on disorders such as Down’s syndrome.

Chromosome 21 is the smallest of the 23 pairs of human chromosomes. Children suffering from Down’s syndrome inherit three copies of chromosome 21, instead of two.

The achievement caps 13 years of research at London’s National Institute for Medical Health and the Institute of Neurology. In their report in the journal Science, researchers describe how they mixed the human chromosome with mouse embryonic stem cells. Those that absorbed chromosome 21 were then injected into mouse embryo which was re-implanted into the mother. The resulting mice have a copy of the human chromosome. Although they look normal, they show various features associated with Down’s syndrome.

Imagine the world with out Down's syndrome. So many lives are affected by this disorder. It may not stop with Down's either. This same technique can be applied to other disorders, such as Edward's syndrome and Patau's syndrome.
