Abstract: Described herein are tissue grafts derived from the placenta that possess good adhesion to biological tissues and are useful in wound healing applications. In one aspect, the tissue graft includes (1) two or more layers of amnion, wherein at least one layer of amnion is cross-linked, (2) two or more layers of chorion, wherein at least one layer of chorion is cross-linked, or (3) one or more layers of amnion and chorion, wherein at least one layer of amnion and/or chorion is cross-linked. In another aspect, the grafts are composed of amnion and chorion cross-linked with one another. In a further aspect, the grafts have one or more layers sandwiched between the amnion and chorion membranes. The amnion and/or the chorion are treated with a cross-linking agent prior to the formation of the graft. The presence of the cross-linking agent present on the graft also enhances adhesion to the biological tissue of interest. Also described herein are methods for making and using the tissue grafts.

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.

Abstract: Disclosed herewith is a method for inducing angiogenesis using modified placental tissue or an extract thereof to treat conditions other than cardiovascular conditions.
Abstract: Described herein are compositions of collagen and micronized placental tissue components, methods for producing the same and methods for using the same for wound healing, repairing damaged tendons, cosmetic applications and covering biocompatible materials and/or devices.
Abstract: The invention relates to implantable collagen devices made by seeding at least one elongate collagen construct, e.g., comprising at least one elongate synthetic collagen fiber with a plurality of cells and applying a strain and/or stress to the at least one elongate collagen fiber to induce the cells to differentiate into target phenotypes, e.g., tendon or ligament phenotype cells (and/or fibroblasts), typically with an extracellular matrix of collagen to organize into a tissue on the at least one collagen fiber.
