Abstract
The present invention discloses a composite made of a layer of epithelial cells cultured together with a dermal matrix in a culture medium, which is free of BPE. The dermal matrix is a substantially non-immunogenic human dermis. Also disclosed is an enhanced composite where a biological agent has been introduced into the epithelial cells. The invention also comprises methods of making and implanting both the composite and the enhanced composite in an animal. A method of treating disease or injury through the use of the disclosed composites is also part of the present invention.
