We have now CRISPR'd a human!
A group of Chinese scientists have become the first to use the game-changing gene-editing technology CRISPR-Cas9 on humans. Nature reported today that a team from Sichuan University inserted genetically modified cells into a patient with aggressive lung cancer in October.
CRISPR allows scientists to easily edit small bits of DNA in order to remove troubling traits or alter a gene to particular specifications. The idea in the Chinese clinical trial is to use CRISPR to edit immune-system T cells, reprogramming them to destroy cancerous ones. The researchers plan to remove T cells from the blood of lung cancer patients, then delete a particular gene for a molecule called PD-1, which helps cancer spread.
