Their would be no advantage of using ones own skin. First alloderm or cymetra do not have a problem with rejection. Porcine Urinary Bladder Matrix and cymetra both provide the basic structure to allow the body to revascularize but the difference is the UBM triggers the bodies imune system to fix the area. I do not know if if can fix nerves but I am hoping it can help in time. Can take many months to get full effect. The following came from the acell website:

UBM appears to fundamentally change the healing response by providing signals to the host immune system that stimulate an adaptive or accommodative response, conducive for wound healing and three-dimensional growth of various cell types.6 UBM has been shown to:
Recruit progenitor cells7
Demonstrate chemotactic and mitogenic activities8
Constructively remodel site-specific tissues where scarring would be expected5

I should also point out that i had cymetra a year ago and it did beef me up a bit but really did not change how it feels.
