Question: Do you think if we used some skin replicants we could heal serious cuts? For example if someone was shot in war could we close the wound with animal or human skin or just a replicant?

Jason Chu answered on 6 Jun 2018:

Ideally yes, something like this would be very helpful to heal serious cuts and wounds.
However, our body is very resistant and will reject anything that isn’t us. So if we tried to cover or “graft” damaged skin with animal / human skin (that isn’t identical to us), our body would reject it and react badly to it.
However, if we could very quickly grow our own cells in a plate – or use something to promote skin repair in our bodies. This would overcome that problem. But we are far away from an ideal answer right now!
