We have been cultivating human epidermal cells for therapeutic purpose according to the original methods developed by Rheinwald and Green. Cultured epithelium (CE) was applied to patients with severe skin defects, burn wounds, chronic skin ulcers and cutaneous disorders like hypomelanosis. Autologous CE allows to restore massive skin surface in a short period compared with other conventional treatments. For grafts take, it is important to manage wound beds properly prior to CE grafting. The CDS was applied to prepare wound bed acceptable for CE grafting. The CDS was designed to secrete various types of cytokines, i.e., VEGF and KGF to stimulate wound healing. The successful management of deep wounds like chronic skin ulcer or burn ulcer requires granulation tissue formation and epithelialization to wound closure. This study aimed to evaluate the application of CDS in conjunction with CE for patients with chronic skin ulcer and burn ulcer. In some cases the wounds were cured by using CDS, and followed by CE grafting. All clinical trials achieved excellent or good results, showing no contracture and no hypertrophic scar after wound closure. The CDS was found to be useful to prepare wound beds and to facilitate wound management.
