A Follow-up Study to Evaluate the Efficacy and Safety of ALLO-ASC-DFU in ALLO-ASC-EB-101 Clinical Trial

"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.~This study is a follow-up study without intervention.~Other Names:~Allogenic adipose-derived mesenchymal stem cells"
