Restart and reframe the discussion: Once you realize that a shouting match is underway (even if you are part of it), you need to get the parties to step back, turn off the megaphones, and start the discussion all over again.
Still, that was then and this is now, so let's turn the question over to you once more to see if we can smash our heads together and get some knowledge to fall out.
And so we just want to get a sense of the kind of research that you guys are doing, and then maybe I'll turn it over to some young people to see if they've got any questions.
In addition to the extremely expensive process of cloning, for each patient you have to culture stem cells and reliably turn them into the tissue you want with 100% efficiency, so you don't get a single left over stem cell that will cause tumors.
