Abstract
The present invention relates to a living skin replacement. In particular, it relates to a biosynthetic dressing material composed of a living stromal tissue prepared from stromal cells such as fibroblasts cultured upon a three-dimensional framework and a transitional covering which acts as an epidermal replacement. Such a living skin replacement provides long-term biologic coverage of full-thickness wound defects. Since human fibroblasts are known to be relatively non-antigenic when transferred to allogeneic hosts, a temporary living skin replacement made up of such cells attached to a transitional covering may replace the use of cadaveric skin allografts for achieving temporary wound closure in cases where the patients lack enough healthy skin for autografts.
