Abstract
The present invention relates to in vitro cultured skin tissue, and in particular to cultured skin tissue comprising exogenous genes encoding angiogenic growth factors. In some embodiments, the keratinocytes express exogenous angiopoietin-1 or a member of the VEGF family, preferably VEGF-A. In particularly preferred embodiments, the keratinocytes are incorporated into cultured skin tissue.
Claims5
A composition comprising NIKS (Near Diploid Immortalized Keratinocyte) cells, said NIKS cells comprising an exogenous VEGF gene operably linked to a promoter, wherein said NIKS cells are stably transfected with said exogenous VEGF gene, which cells have the characteristics of cells deposited as cell line ATCC PTA-9170, which cells are stratified into squamous epithelia, thereby forming cultured skin tissue, and express said VEGF gene.
