  • Patent number: 9532866
    Abstract: An acellular dermal graft is provided. The acellular dermal graft may be useful in minimizing side effects caused after transplantation since an environment favorable for formation of new blood vessels and proliferation of autologous tissues is provided by forming a multi-penetration structure in an acellular dermal tissue, removing a basement membrane layer and/or subjecting corners to slope cutting, and transplantation is stably performed within a short transplantation time due to improved extensibility and flexibility of tissues. The acellular dermal graft may be useful in reducing a time required to recover tissues after transplantation since the transplantation is stably performed due to improved grafting reaction with a host tissue by enhancing uptake of fibroblasts and promoting angiogenic activities.
