Enriched multilayer amnion derived tissue graft

机译:富含多层羊膜衍生的组织移植物

摘要

An enriched amnion derived tissue graft has a stromal matrix layer and an epithelium layer. A stromal matrix layer may contain a basement membrane layer, a compact layer, a fibroblast layer, and an intermediate layer. An amnion derived tissue graft may have a plurality of tissue layers and the layers may be configured with the epithelium layers toward the inside and the stromal matrix layers toward the outside surface. An enriched portion may be coated onto or be configured within a tissue layer and have an increased concentration of cells, of proteins, growth factors, seed cells, pharmaceuticals or any combination thereof. A carrier fluid such as amniotic fluid may be used to produce an enrichment composition for coating the tissue graft. The cells within the enriched portion may be stem cells from the amnion, or cells from other tissue and may be seed cells selected based on the treatment location.
