Provided herein are soluble bioactive factor solutions, grafting scaffolds containing the bioactive factor solutions, and methods of making and using the same.

Provided herein are improved compositions and methods of making and using the same, the composition comprising a polymer and a ceramic present at a ratio of from 3:1 to 1:3 of polymer:ceramic by weight, wherein the composition comprises or is a composite of the polymer and the ceramic having improved printability and/or having an improved elastic modulus and/or improved stress at failure (e.g., as compared to a blend of the polymer and the ceramic). Improved medical implants incorporating the same are also provided.

A biological composition made from a mixture of biologic material intermixed with an electrospun matrix for direct implantation has a mixture of biologic material and a volume of an electrospun matrix of collagen. The mixture of biologic material has non-whole cellular components including vesicular components and active and inactive components of biological activity, cell fragments, cellular excretions, cellular derivatives, and extracellular components, or whole cells or combinations of the non-whole cellular components and whole cells. The mixture is compatible with biologic function. The volume of electrospun matrix of collagen is intermixed with the mixture of biologic material. The electrospun matrix forms a three-dimensional electrospun scaffold externally enveloping each of the non-whole cellular components, if any, and each of the whole cells, if any, of the mixture of biologic material to form a biological composition of paracrine-enriched collagen fleece.

The invention is directed to a composition comprising all or a portion of a beta-tricalcium phosphate (-TCP) bound to all or a portion of a -TCP binding peptide and methods of use thereof.

A method comprising the steps of applying an adhesive composition to a substrate bone repair region. The adhesive composition comprises a porous, biocompatible, biodegradable, resorbable, non-toxic, and polymerizable composition. The substrate bone repair region comprises a bone structure, implant or device surface, or tooth surface. The adhesive composition is cured to provide a polymerized adhesive composition resulting in repairing or augmenting the substrate bone repair region. The adhesive composition may be mixed with a bone graft material before application. The adhesive composition may be additionally applied to a barrier membrane that is placed over the substrate bone repair region where the adhesive composition or combination of adhesive composition and bone graft material is applied.

An object of the present invention is to provide a method for producing a gelatin formed body having a minimized content of a component harmful to a living body and high biocompatibility with high shaping accuracy, and a gelatin formed body produced by the method. According to the present invention, provided is a method for producing a gelatin formed body, the method including: a step a of forming, on a substrate, a layer containing a powder which is obtained by air-drying an aqueous gelatin solution and has an average particle diameter of 25 to 200 m; and a step b of jetting liquid droplets of an aqueous solution containing alcohols having a boiling point of 120 C. or lower toward the layer formed in the step a from a nozzle and flying the jetted liquid droplets so that the liquid droplets are landed on the layer formed in the step a, thereby forming a gelatin formed body.

The present disclosure describes methods of treating an injury in a subject using placental tissue streamers, engineered tissue placental tissue hybrids, suture placental tissue hybrids, placental tissue patch hybrids, and tissue hybrids, and the use of these compositions to repair, treat, or support an injury or degenerative process in a subject.

The present invention provides muscle-derived progenitor cells that show long-term survival following transplantation into body tissues and which can augment non-soft tissue following introduction (e.g. via injection, transplantation, or implantation) into a site of non-soft tissue (e.g. bone) when combined with a biocompatible matrix, preferably SIS. The invention further provides methods of using compositions comprising muscle-derived progenitor cells with a biocompatible matrix for the augmentation and bulking of mammalian, including human, bone tissues in the treatment of various functional conditions, including osteoporosis, Paget's Disease, osteogenesis imperfecta, bone fracture, osteomalacia, decrease in bone trabecular strength, decrease in bone cortical strength and decrease in bone density with old age.

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.
