Scientists yesterday announced a breakthrough that could transform research into a range of incurable diseases but spark a dramatic increase in the number of monkeys used in experiments. Researchers have developed a technique to create genetically modified monkeys that suffer from human illnesses. Experimenting on these monkeys, they believe, will advance our understanding and treatment of incurable conditions such as Parkinson’s disease and multiple sclerosis. However, the scientific breakthrough has caused consternation among groups opposed to animal experiments because the development will almost certainly lead to a sudden increase in the number of primates used in medical research at a time when there are calls for fewer monkeys to be used in experiments. The development also raises the prospect that we will be able to apply the technique to humans – another primate. This could help families affected by inherited disorders such Huntington’s disease and cystic fibrosis by permenantly eradicating their defective genes from future generations. The breakthrough was achieved by a team of scientists in Japan led by Erika Sasaki of the Central Institute of Experimental Animals in Kawasaki and Professor Hideyuki Okano of Keio University School of Medicine. Their study, published in the journal Nature, […]
