  • Publication number: 20230414670
    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.

  • Patent number: 11602549
    Abstract: Described herein are tissue grafts derived from the placenta with improved physical and biological properties. In one aspect, the tissue graft includes a first membrane comprising Wharton's jelly laminated with amnion, chorion, or a combination thereof. The presence of Wharton's jelly in the grafts enhances the performance of allograft amniotic-derived, caderivic allograft, xenograft, or alloplast soft tissue substitutes.

  • Patent number: 11338063
    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.

  • Publication number: 20190307812
    Abstract: The present invention provides compositions and formulations of micronized Wharton's jelly having a controlled viscosity such that when delivered to the injured region of a subject, it remains substantially localized with little or no migration out of the injured region for the repair and/or regeneration thereof. Micronized Wharton's Jelly can be suspended in a pharmaceutically acceptable aqueous carrier, such as saline, sterile water, or any suitable buffer, to form a suspension or a gelatinous gel composition, or it can be in the form of a paste, suitable for delivery into the space adjacent the articular surface cartilage injured region of a subject. The micronized Wharton's jelly when employed at sufficient concentrations can be hydrated into a gel or paste and administered topically, or it can be injected into the body through the use of a needle and syringe.
