This is an open-label follow up study to evaluate the efficacy and safety for the subjects with ALLO-ASC-DFU treatment in phase 1/2 clinical trial (ALLO-ASC-EB-101) for 24 months.~ALLO-ASC-DFU is a hydrogel sheet containing allogenic adipose-derived mesenchymal stem cells. Adipose-derived stem cells have anti-inflammatory effect and release growth factors such as vascular endothelial growth factor(VEGF) and hepatocyte growth factor (HGF), which can enhance wound healing and regeneration of new tissue, finally may provide a new option in treating a Dystrophic Epidermolysis Bullosa.
