First human Crispr gene-editing trial gets early approval
Since T cells do not reproduce by themselves, I presume the effects of modified T cells will only last until the cells exist in the body. This reminds me of a question I was wondering about since I heard about Crispr: can we use this method to make permanent changes in the DNA of grown up humans, and if so, do we have clear understanding of how to do it?<p>The thing that puzzles me most is that if we do it by creating some cells and injecting them, how do we guarantee that these cells replace their existing unmodified counterparts?
