TISSUE MATRICES INCORPORATING MULTIPLE TISSUE TYPES

The present disclosure provides tissue products produced from extracellular tissue matrices. The tissue products can include acellular extracellular matrices including combinations of different tissue types. The combination can harness various properties of the different tissues to provide improved composite structures with desired mechanical and/or biologic properties.

COMPOSITION OF COLLAGEN PEPTIDE AND ELASTIN PEPTIDE, METHOD OF PRODUCING THE SAME AND USE THEREOF

Disclosed is a composition of a collagen peptide and an elastin peptide, method of producing the same and use thereof. The composition of the present disclosure consists of a collagen peptide and an elastin peptide; the collagen peptide is prepared by enzymatic hydrolysis of a collagen material with pepsin or trypsin, and the elastin peptide is prepared by enzymatic hydrolysis of an elastin material with papain and/or protease Protamex. In the present disclosure, an elastin peptide and a collagen peptide with molecular weight in a specific range are prepared by specific processes, and the composition composed of the two at a suitable ratio can simultaneously and significantly increase the amount of the elastin and collagen in a damaged skin in a small usage amount, and significantly increase the content of hyaluronic acid and hydroxyproline while decrease the content of MMP3, meanwhile, inhibit skin inflammatory factors.

COLLAGEN REINFORCED TISSUE GRAFTS
20200215221 · 2020-07-09 ·

This invention is directed to a multi-layered tissue graft comprising a collagen layer and at least one separated and washed placental tissue component and/or umbilical cord component, wherein the collagen is human collagen substantially free of non-human antigens.

Silk microspheres and methods for surface lubrication

Provided herein relates to compositions and methods for lubrication of a surface. The surface amenable to the compositions and methods described herein can be a non-biological surface, a biological surface, or a combination thereof. In some embodiments, the composition comprising a phospholipid-coated silk microsphere can be used for lubrication of a surface. In some embodiments, the composition comprising a phospholipid-coated silk microsphere can be used for joint lubrication, e.g., for treatment of joint disorders such as arthritis.

Thermosensitive phosphazene-based polymer comrising sulfonated moiety, and preparation method and use thereof
20200048377 · 2020-02-13 ·

Provided is a thermosensitive phosphazene-based polymer including an amino acid ester moiety, a polyethyleneglycol moiety, and a moiety including a sulfate group linked directly or by a linker in a predetermined ratio, a method of preparing the same, and a hydrogel-formable composition including the same. For example, a hydrogel formed from the composition may be used for tissue regeneration or drug delivery or used as a storage, a body tissue regeneration inducer, or a filler in a body.

Cell bandage

The invention provides a method for delivering cells across the surface of a tissue, the method comprising distributing the cells on and/or within a biomaterial to form a cell bandage and applying the cell bandage to the surface, wherein, after application of the cell bandage to the surface of the tissue, the cells are released from the cell bandage. Further provided is a method for bonding two or more tissues, the method comprising providing a cell bandage in intimate contact with the surfaces to be joined, wherein the cell bandage comprises a biomaterial, said biomaterial having cells distributed on and/or within it.

DENTAL TREATMENT METHOD AND ABUTMENT USED THEREIN

A dental treatment method is provided. In this method, a tooth of a patient is extracted and prepared to provide a root part. A root canal in the extracted tooth is prepared and treated. A post of an abutment is fitted into the root canal to attach the root part to the abutment. The abutment having the root part is attached to a dental implant. With the root part attached to the abutment, periodontal connective tissue maintains the jaw bone associated with the extracted tooth, without significant hard tissue loss.

Method of producing a film connective tissue body using a connective tissue body formation substrate

The present invention provides a connective tissue body formation substrate which can form a film connective tissue having a desired thickness and both surfaces in a desired surface condition without prolonging the time required for formation of the connective tissue. Specifically, two tissue formation surfaces 2a and 2b are faced with each other with a tissue formation space 3 being interposed therebetween. A slit 9 is formed in the tissue formation surface 2b so that the tissue formation space 3 communicates with an outside of the substrate. A connective tissue body formation substrate 1 is installed in an environment where a biological tissue material is present. A connective tissue intrudes into the tissue formation space 3 from the slit 9. Both surfaces of the film connective tissue are formed so as to match the substrate surface.
