Abstract: This invention is directed to a multi-layered tissue graft comprising a collagen layer and at least one separated and washed placental tissue component and/or umbilical cord component, wherein the collagen is human collagen substantially free of non-human antigens.
Abstract: Described herewith are compositions comprising placental growth factors and methods for non-surgical, localized delivery thereof. The composition is delivered to a diseased or injured organ and/or body part and is formulated in a manner which allows for localized retention of the composition at the site of delivery.
Abstract: The present disclosure provides methods of treating defects such as wrinkles or scars via a subdermal injection of placental tissue components. It also provides placental tissue compositions maintained within the barrel of a syringe, which may be for use in treating such defects.

Abstract: Provided herein are micronized placental compositions composed of micronized placental tissue component, such as amnion or chorion and/or filler bound to one or more chelating agents, which in turn are optionally bound, reversibly, to pharmacologically active metal ions. Further provided are methods of making and using the placental compositions. The compositions have numerous therapeutic applications.
Abstract: Described herein are placental tissue grafts produced by chemical dehydration followed by freeze-drying the placental tissue to produce the tissue graft. The tissue grafts retain their biological properties preferably at the same level as the placental tissues before they are processed. The placental tissue grafts have numerous medical applications. Methods for making the tissue graft compositions are also described herein.

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.
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: Described herein are compositions composed of micronized placental components and pharmaceutical compositions thereof. The compositions have numerous medical applications. Methods for making and using the micronized compositions are also described herein.

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.

Abstract: Provided herein are NDGA polymers and metal complexes of such polymers, preferably those metal complexes of the polymers that are insoluble or substantially insoluble in an aqueous solvent, and processes for making the same.
Abstract: Described herein are tissue grafts derived from the placenta that possess good adhesion to biological tissues and are useful in would 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 amnion 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.
