Abstract: Methods and compositions for preparing and priming a tissue graft for an accelerated therapeutic effect are provided herein. In one embodiment, the method includes obtaining a tissue containing viable cells from a donor, wherein the viable cells are endogenous to the tissue and remain resident in the tissue; and priming the viable cells with one or more stimuli comprising simulated hypoxia to produce a primed tissue, wherein when grafted to a recipient the primed tissue provides a benefit compared to non-primed tissue.

Abstract: Compositions including a first soft tissue-derived matrix and a second soft tissue-derived matrix are provided, as well as methods of making such compositions. In some embodiments, the composition comprises delipidated, decellularized adipose tissue-derived matrix and delipidated, decellularized fascial tissue-derived matrix, which may be combined in various proportions. Such adipose-fascia matrix compositions provide improved volume retention when implanted into a patient. The composition may further include exogenous cells or other substances, and/or a carrier. The composition is suitable for use in plastic surgery procedures, including reconstructive or cosmetic surgery procedures, as well as procedures for wound treatment and tissue regeneration.

Abstract: Diversified grafts suitable for use in repair and reconstruction procedures are provided. Some diversified grafts comprise two or more heterogenous features which form regions having different preferred properties. A diversified graft useful for pre-pectoral breast reconstruction, meshing is provided on an upper pole of the diversified graft and a plurality of slits arranged in particular patterns is provided on a lower pole of the graft, whereby the upper pole has a greater expansion ability and the lower pole has lesser degree of expansion ability but maintains greater load bearing capacity which is necessary to support the lower pole of the breast undergoing reconstruction, while allowing for fluid egress. In other embodiments, the diversified graft comprises two or more components which are combined by attaching them to each other to form a larger graft of the required size. The components may be smaller pieces of the same material or different materials.

Abstract: Multiple component grafts are provided for treatment of tissue defects and comprise two or more components, each of which is a tissue-derived matrix and at least two of which are derived from different types of tissue. For example, a first component may be a matrix derived from cartilage tissue such as cartilage fibers with or without viable cells, cartilage particles with or without viable cells, or combinations of any two or more such cartilage-derived matrices. A second component may be a matrix derived from bone tissue such as mineralized or demineralized cortical bone fibers, viable cancellous bone matrix (e.g., cryopreserved or lyophilized chips, particulates, powder, sheets, putty, flowable fluid, etc.), demineralized or demineralized cancellous bone matrix (chips, particulates, powder, sheets, putty, flowable fluid, etc.), or combinations of any two or more of such bone-derived matrices. Also provided are methods for making and using such multiple component grafts.

Abstract: Compositions including a first soft tissue-derived matrix and a second soft tissue-derived matrix are provided, as well as methods of making such compositions. In some embodiments, the composition comprises dilapidated, decellularized adipose tissue-derived matrix and dilapidated, decellularized fascial tissue-derived matrix, which may be combined in various proportions. Such adipose-fascia matrix compositions provide improved volume retention when implanted into a patient. The composition may further include exogenous cells or other substances, and/or a carrier. The composition is suitable for use in plastic surgery procedures, including reconstructive or cosmetic surgery procedures, as well as procedures for wound treatment and tissue regeneration.

Abstract: Tissue derived porous matrices for treating wounds are provided, as well as methods for making and using them. The tissue derived porous matrices comprise processed tissue of any of several types, such as dermis, adipose, etc., and have a plurality of interconnected pores which allow fluid flow through the matrices. The tissue derived matrices are biocompatible resorbable matrices which remodel with native tissue and facilitate and enhance cell infiltration and tissue ingrowth into the matrices during the wound healing process, thereby enhancing wound healing and tissue remodeling when implanted into a patient. The tissue derived matrices are useful with reduced or negative pressure wound healing methods and systems, without the need to repeatedly revisit the treatment site and remove previously implanted matrices.

Abstract: A dermal tissue allograft includes a dermal matrix having a profile including first and second vertices, a first imaginary axis extending between the first and second vertices, a first peripheral edge extending along a continuous path from the first vertex to the second vertex on a first side of the first imaginary axis, and a second peripheral edge extending along a continuous path from the first vertex to the second vertex on a second side of the first imaginary axis. The first peripheral edge includes an apogee, a convex portion, and a concave portion. The convex and concave portions meet at a transition point located on the first peripheral edge between its apogee and the second vertex. The second peripheral edge includes an apogee and is convex. The second perpendicular distance is greater than the first perpendicular distance. The dermal matrix has a substantially uniform thickness across its profile.

Abstract: The present invention relates generally to tissue forms useful as grafts or implants and derived from membranous tissue. The tissue forms may contain viable endogenous cells. The tissue forms may be sheets or mini sheets, each having quadrilateral, circular, polygonal, or irregular shapes. The sheet tissue form may have a generally quadrilateral shape, with an average length of about 1 to about 20 centimeters and an average width of about 1 to about 20 centimeters. The mini sheet tissue form may have a generally quadrilateral shape, with an average length of about 0.5 to about 9 millimeters and an average width of about 0.5 to about 9 millimeters. A mixture of the mini sheet tissue form and a liquid, such as cryopreservation fluid, saline or buffer solution, is flowable, which means the mixture will pass through a luer-slip tip syringe, or a gauge needle.
