Re: Red...A little help
Sorry I actually wrote a long response on CRISPER and thought it got posted....alas it did not. I went back hours later and my post would not go as my sign in had ended. Bummer it took me a few minutes to write.
So short form.
Is the question about fidelity of insertion (correct site change and only correct site) That answer is ‘Pretty good now” as new tricks to limit off target insertions are looking pretty precise. Or is the question how do we make changes in every cell? And that answer is we don’t. We sometimes use stem cells and grow them out, and many applications have evolved using T cell alterations for cancer immunotherapy, and again you can grow those up to get tens and hundreds of millions of ‘changed cells’. But we are not able to simply inject ‘vectors’ and change cells in the body universally or even just targeting organ specific effects like fixing kidneys or fixing liver genetics etc. Those kinds of applications are futuristic and not currently feasible.
So did I get the questions right?
