A full-function artificial organ fitting body comprises a cortex layer and an organ body tissue area. The organ body tissue area comprises a growth area, a differentiation area, a docking area, a branch arterial system, a branch nervous system and a branch venous system. The branch arterial system, the branch nervous system and the branch venous system are distributed in the differentiation area and form a main body three-dimensional skeleton structure with the outer growth area and the middle docking area.

Provided herein are compositions and methods for treating a subject with damaged tissue, such as an injury associated with a tissue to tissue (e.g., a connective tissue-to-connective tissue or tissue to bone) interface. One aspect provides an adhesive film or adhesive layer, optionally comprising a biomaterial, tissue growth factors, including CTGF/CCN2, or cells.

The present application provides methods of functionalizing an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal or by culturing an organ or tissue in a bioreactor containing such nutrient. The present application also provides methods of selectively functionalizing extracellular matrix (ECM) of an organ or tissue of a mammal by administering a nutrient (e.g., peracetylated N-azido galactosamine Ac4GalNAz) to the mammal. In some aspects, the present application provides a decellularized scaffold of a mammalian organ or tissue comprising an extracellular matrix, wherein the extracellular matrix of the decellularized scaffold is functionalized with a chemical group that is reactive in a bioorthogonal chemical reaction, such as an azide chemical group. The present application also provides biological prosthetic mesh and mammalian organs and tissues for transplantation prepared according to the methods of the application.

The present invention relates to settable compositions for use in surgery. The invention also provides related compositions, including surgical kits and packages, as well as methods of making and using the settable compositions.

The invention provides articles of manufacture comprising biocompatible nanostructures comprising nanotubes and nanopores for, e.g., organ, tissue and/or cell growth, e.g., for bone, kidney or liver growth, and uses thereof, e.g., for in vitro testing, in vivo implants, including their use in making and using artificial organs, and related therapeutics. The invention provides lock-in nanostructures comprising a plurality of nanopores or nanotubes, wherein the nanopore or nanotube entrance has a smaller diameter or size than the rest (the interior) of the nanopore or nanotube. The invention also provides dual structured biomaterial comprising micro- or macro-pores and nanopores. The invention provides biomaterials having a surface comprising a plurality of enlarged diameter nanopores and/or nanotubes.

The present disclosure relates to the technical field of medicines, and in particular, to a composite scaffold material, a preparation method therefor and use thereof. The present disclosure provides a composite scaffold material, including a charged fiber framework material. The fiber framework material is coated with positively charged biocompatible materials and negatively charged biocompatible materials alternately, by means of electrostatic attraction. The composite scaffold material of the present disclosure overcomes the defects of traditional scaffold materials, such as poor hydrophilicity, biocompatibility, histiocyte adhesion ability, and biological induction activity. The composite scaffold material has better applicability when used for tissue adhesion, closure, leaking stoppage, hemostasis, isolation, repair, and adhesion prevention, and can also be used for preparing a drug carrier (e.g., sustained release carrier) and a tissue engineering scaffold material. Therefore the composite scaffold material has a wide range of industrial uses.

Described herein are methods that result in less cell death resulting from myocardial infarction than would otherwise occur in an individual who has suffered myocardial infarction. Also described are compositions useful in reducing cell death post myocardial infarction.

The present disclosure describes the use of nerve conduits as scaffolds for nerve regeneration, including spinal cord regeneration. The conduit may be hollow or contain a luminal filler such as agar or other biocompatible material.

An implantable medical product and method of use for substantially reducing or eliminating harsh biological responses associated with conventionally implanted medical devices, including inflammation, infection and thrombogenesis, when implanted in in a body of a warm blooded mammal. The bioremodelable pouch structure is configured and sized to receive, encase and retain an electrical medical device therein and to allow such device to be inserted into the internal region or cavity of the pouch structure; with the pouch structure formed from either: (a) first and second sheets, or (b) a single sheet having first and second sheet portions. After receiving the electrical device, the edges around the opening are closed by suturing or stapling. The medical device encased by the bioremodelable pouch structure effectively improves biological functions by promoting tissue regeneration, modulated healing of adjacent tissue or growth of new tissue when implanted in the body of the mammal.

Osteoconductive synthetic bone grafts are provided in which porous metallic matrices are loaded with an osteoinductive protein. In certain embodiments, the grafts include porous ceramic granules deposited within the matrices.
