Abstract
The present invention utilizes AAV as a vector to transfect epithelial cells with an AAV/heterologous gene containing/Neo vector, to form a heterologous protein secreting culture of epithelial cells. This culture is useful for preparing recombinant skin using the organotypic epithelial raft culture system. The sheets of epithelial cells is composed of a stratified sqaumous epithelium composed of a lower layer of immature basal cells and an upper layer of mature keratinized epithelium. The rAAV virus stock prepared without wild type AAV is useful in expressing heterologous protein, however, the maximum production of the heterologous protein was achieved; when the rAAV virus stock contained wild type AAV. This invention discloses that AAV is appropriate for genetically altering skin to secrete new proteins to treat diseases and skin disorders or conditions.
