Disclosed herein is a composition comprising stimulated biological material derived from an interface compartment, wherein the composition is capable of augmenting the generation or healing of a native tissue when administered to a subject in need thereof.

An example biological tissue graft includes a body formed from a flexible biological tissue, the body having a first end and a second end opposite the first end. The biological tissue graft also includes an aperture positioned in the second end of the body that is sized to receive the first end of the body therethrough.

Disclosed herein is a composition comprising stimulated biological material derived from an interface compartment, wherein the composition is capable of augmenting the generation or healing of a native tissue when administered to a subject in need thereof.

The present invention provides a method for forming a connective tissue body, which enables extending the ranges of design values in terms of shape, dimension, etc., of the connective tissue body. This method comprises: a fat treatment step for removing fat contained in a connective tissue body, which is formed in an environment where a biological tissue material is present, from the interior of the connective tissue body while the connective tissue body is being set in a molding tool, and for causing the shape of the connective tissue body to follow the shape of the molding tool; and a bioinert solution treatment step for immersing the connective tissue body, together with the molding tool, in a bioinert solution while the connective tissue body is being shaped so as to follow the shape of the molding tool after the fat treatment step.

Methods are described for generating autologous tissue grafts, including generating grafts at the point of care, which include isolated cell populations that are enriched with stem cells and are mixed with biological fillers including hyaluronic acid and derivatives thereof. The hyaluronic acid localizes the cells to a desired injection site and stimulates collagen production thus enhancing the viability and the longevity of the graft.

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 subject invention pertains to multifunctional tendon-mimetic hydrogels constructed from anisotropic assembly of aramid nanofiber composites. The stiff nanofibers and soft polyvinyl alcohol in these anisotropic composite hydrogels (ACHs) mimic the structural interplay between aligned collagen fibers and proteoglycans in tendons. The ACHs uniquely exhibit a high modulus of ?1.1 GPa, strength of ?72 MPa, fracture toughness of 7333 J/m.sup.2, and many additional characteristics matching those of natural tendons. The surfaces of ACHs can be functionalized with bioactive molecules to present biophysical cues for the modulation of morphology, phenotypes, and other behaviors of attached cells. Moreover, soft bioelectronic components can be integrated on ACHs, enabling in-situ stimulation and sensing of various physiological parameters. The outstanding mechanics and functionality of these tendon-mimetics can be advantageously applied to advanced tissue engineering, implantable prosthetics, human-machine interactions, and other technologies.

A method for reattaching a detached tissue to a hard tissue includes operation in which a suture anchor having a first stitch and a second stitch is provided, wherein the first stitch is divided into a first strand and a second strand, and the second stitch is divided into a third strand and a fourth strand. The suture anchor is fixed on a hard tissue. The first strand, the second strand, the third strand and the fourth strand pass through a detached tissue. A bioinductive patch is provided, wherein the bioinductive patch includes a patch body and a button. The first strand and the third strand pass through the patch body and a first suture hole of the button, and the second strand and the fourth strand pass through the patch body and a second suture hole of the button. The second strand and the third strand are knotted to form a first strand node, and the first strand node presses the bioinductive patch and the detached tissue tightly onto the hard tissue.

A bioinductive patch includes a patch body and a button. The patch body has an inner space. The button is disposed in the inner space of the patch body. A method for manufacturing a bioinductive patch includes step in which a patch body having an inner space is provided. The method continues with step in which a button is disposed in the inner space of the patch body.
