CRISPR-Cas9 is a genome editing tool. It is a unique technology that enables geneticists and medical researchers to edit parts of the genome by removing, adding or altering sections of the DNA sequence. It is faster, cheaper and more accurate than previous techniques of editing DNA and has a wide range of potential applications.
11/08/17 GM pigs take step to being organ donors
The most genetically modified animals in existence have been created to help end a shortage of organs for transplant, say US researchers.
The scientists successfully rid 37 pigs of viruses hiding in their DNA, overcoming one of the big barriers to transplanting pig organs to people. The team at eGenesis admits preventing pig organs from being rejected by the human body remains a huge challenge. But experts said it was a promising and exciting first step.
01/02/17 Genome editing technology, CRISPR/Cas9, used to produce bovine tuberculosis resistant cattle
Researchers from Northwest A&F University might have produced bovine tuberculosis resistant cattle using the genome editing technology, CRISPR/Cas9. Previously, a mouse gene was inserted into cattle in an attempt to boost protection against TB. Bovine TB is a risk in many countries, including parts of the UK, Africa and Asia therefore this technology could have widespread uses in agriculture. However, it is not clear what would happen if the transgenic cattle were exposed to tuberculosis in normal conditions.
