Reconstructed Skin from Cultured Human Keratinocytes and Fibroblasts on a Collagen-Glycosaminoglycan Biopolymer Substrate

A lattice prepared from biopolymer substrate bovine skin collagen and chondroitin-6-sulfate (glycosaminoglycan) served as a support for normal human keratinocytes and fibroblasts. Air exposure of the lattice on an agarose block gave rise to reconstructed epidermis, the histological features of which are very similar to normal human epidermis. Indirect immunofluorescence staining of the plasma membrane-associated transglutaminase, the enzyme...
