A bioscaffold made from an isolated cardiac fibroblast-derived 3-dimensional extracellular matrix (ECM) is disclosed. The bioscaffold can be used as an epicardial patch for the delivery of therapeutic cells into myocardial tissue. Methods of making the 3-dimensional extracellular matrix using cultured cardiac fibroblasts are also disclosed.

ECM based compositions including amniotic membrane and methods for employing same to treat cardiovascular disorders.

The present invention relates to a peripheral nerve-specific hydrogel material, which is deliverable in a minimally invasive fashion, sustains the growth of neurons, and speeds recovery following surgical reconstruction.

A method for making a porous devitalised scaffold suitable for use in repair of osseous, chondral, or osteochondral defects in a mammal comprises the steps of providing micronized extracellular matrix (ECM) tissue, mixing the micronized extracellular matrix with a liquid to provide a slurry, and freeze-drying the slurry to provide the porous scaffold. A porous scaffold suitable for use in repair of osseous, chondral, or osteochondral defects in a mammal and comprising a porous freeze-dried matrix formed from micronised decellularised extracellular matrix tissue is also described.

Provided herein are improved methods of decellularizing pancreas and other tissues. The methods according to some embodiments are water-based and may be detergent-free, allowing for the production of acellular scaffolds whereby the matrisome is better preserved. Compositions comprising decellularized tissue and methods of use thereof are also provided.

The present disclosure relates to tissue matrix products. The products can includes tissue matrices that have holes or perforations located at certain positions to improve certain in vivo functions without substantial loss of strength or other important properties.

Methods of making a biologically active three-dimensional scaffold capable of supporting growth and differentiation of a cell are described. Biologically active three-dimensional scaffold made by the methods of the invention and an engineered tissue made from the scaffolds are described. Fibers of desired porosity can be obtained from non-structural ECM by lyophilization and/or electrospinning which can be useful for numerous tissue engineering applications requiring complex scaffolds, such as wound healing, artificial skin (burns), soft tissue replacement/repair and spinal cord injury.

Disclosed is a root canal filler for non-extracted tooth which causes no internal resorption or external resorption in a tooth with complete root formation, shows no odontoclast, and contributes to the regeneration of a dental tissue in which odontoblasts are smoothly aligned on the dentin wall. After pulpectomy or enlargement/cleaning of an infected root canal, a root canal filler for non-extracted tooth, which comprises tooth pulp stem cells and an extracellular matrix, is inserted into the apical side of the root canal of the non-extracted tooth. The tooth pulp stem cells may be, for example, dental pulp CXCR4-positive cells. It is preferred to attach, to the crown side of the root canal, migration factor(s) including at least one factor selected from among a cell migration factor, a cell proliferation factor, a neurotrophic factor and an angiogenic factor.

The invention provides a method to prepare a graft comprising a recellularized extracellular matrix of a mammalian liver, liver lobe or portion thereof, and a method of using the recellularized extracellular matrix of a mammalian liver, liver lobe or portion thereof.

The presently disclosed subject matter provides a biomimetic organ model, and methods of its production and use. In one exemplary embodiment, the biomimetic organ model can be a multi-layer model including a at least two microchannels and at least one chamber slab with at least one membrane coated with cells disposed between at least one microchannel and the at least one chamber slab. In another exemplary embodiment, the biomimetic organ disease model can be a five-layer model including a first and second microchannel with a membrane-gel layer-membrane coated or encompassing cells disposed between the microchannels. In certain embodiments, at least one device can be coupled to the biomimetic organ model that delivers an agent to at least one microchannel.
