I did see it when you first posted it. I'll take another look at it.
I write it again because no one seemed to pay attention:
In Switzerland there is also a project going on about scar free healing. At the "Kinderspital Zürich" they seem to have invented a skin replacement with all functions of the normal skin. They write that it should heal without scars.
I contacted them and they already test it on childs and in about 1 year they will test it on adults (Though i dont understand why you test something on childs first. But atleast they are already testing it on humans, what is a big step)
Look at this page:
