Genomics, Proteomics and Bioinformatics

"Cultured skin substitutes are improving the lives of many burn patients, but they also have limitations--including an increased susceptibility to infection," says Supp. "Because cultured skin grafts aren't connected to the circulatory system at the time of grafting, they aren't immediately exposed to circulating antibiotic drugs or antibodies from the body's immune system to fight off infection."
This technique reduces a patient's susceptibility to infections, increases the success rate to fthe skin graft survival, and possibly reduces the need for topical antibiotics, which may subsequently contribute to the emergence or resistant bacteria.
Researchers hope to begin testing this approach in an animal model in early 2007. The initial findings are published in the January issue of the Journal of Burn Care and Research.

So, they add the protein "human beta defensin 4" to the skin substitute they are going to graft? is this correct?

Well, indirectly. They used skin cells that were genetically engineered to produce the defensin protein. Here's the abstract of the study, should you want further reading: http://tinyurl.com/yc9c5d
