Abstract: A method for preparing placenta membrane tissue grafts for medical use, includes obtaining a placenta from a subject, cleaning the placenta, separating the chorion tissue from the amniotic membrane, mounting a selected layer of either the chorion tissue or the amniotic membrane onto a drying fixture, dehydrating the selected layer on the drying fixture, and cutting the selected layer into a plurality of tissue grafts. Preferably, the drying fixture includes grooves or raised edges that define the outer contours of each desired tissue graft, after they are cut, and further includes raised or indented logos that emboss the middle area of the tissue grafts during dehydration and that enables an end user to distinguish the top from the bottom side of the graft. The grafts are comprised of single layers of amnion or chorion, multiple layers of amnion or chorion, or multiple layers of a combination of amnion and chorion.
Abstract: An isolated human cell and populations thereof is provided comprising at least one astrocytic phenotype and at least one mesenchymal stem cell phenotype, wherein the mesenchymal stem cell phenotype is not an astrocytic phenotype.

Abstract: Acellular amnion derived therapeutic compositions are described having a number of various compositional embodiments. An acellular amnion derived therapeutic composition has essentially no live or active amniotic cells. The amniotic cells may be destroyed, and the cells and cell debris may be removed from the acellular amnion derived therapeutic composition. An acellular amnion derived therapeutic composition may comprise micronized placental tissue particles, and/or amniotic fluid. An acellular amnion derived therapeutic composition may be a dispersion of micronized amniotic membrane combined with a fluid, such as plasma, saline, amniotic fluid, combinations thereof and the like. An acellular amnion derived therapeutic composition may be combined with a matrix component to form a composite. An acellular amnion derived therapeutic composition may be used in conjunction with a composition comprising viable cells, such as stem cells.

Abstract: 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 onto top and within of 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 level of laminin-5, a cell adhesion bio-active factor show to bind gingival epithelia-cells, found throughout upper portions of the basement membrane.
