Abstract (en)
[origin: WO2009033160A1] Described herein are tissue grafts derived from the placenta. The grafts are composed of at least one layer of amnion tissue where the epithelium layer has been substantially removed in order to expose the basement layer to host cells. By removing the epithelium layer, cells from the host can more readily interact with the cell-adhesion bio-active factors located on top of and within the basement membrane. Also described herein are methods for making and using the tissue grafts. The laminin structure of amnion tissue is nearly identical to that of native human tissue such as, for example, oral mucosa tissue. This includes high levels of laminin-5, a cell adhesion bio-active factor shown to bind gingival epithelia-cells, found throughout upper portions of the basement membrane.
