Devices and methods for nerve regeneration

A nerve regeneration device comprising a bioresorbable conduit and a matrix contained therein having elongate pores aligned with the longitudinal axis of the conduit. The matrix comprises collagen, fibronectin, laminin-1, and laminin-2, wherein the amount, by weight, of laminin-1 or laminin-2 is greater than the amount of fibronectin in the matrix.

COMPOUNDS AND METHODS FOR THE IMMOBILIZATION OF MYOSTATIN-INHIBITORS ON THE EXTRACELLULAR MATRIX BY TRANSGLUTAMINASE
20210138043 · 2021-05-13 ·

The present invention relates to compounds and their use in the treatment of lesions, in tissue regeneration and/or tissue engineering. The compounds act as substrates for enzymes having transglutaminase activity and are suitable for their immobilization and/or attached therapeutic or diagnostic molecules on extracellular matrix (ECM) or synthetic ECM-derived materials, in particular for the immobilization of myostatin inhibitors.

ARTIFICIAL TENDON OR LIGAMENT TISSUE PRODUCED USING THREE-DIMENSIONAL MECHANOSIGNALING CELL CULTURE SYSTEM
20210115396 · 2021-04-22 ·

The present invention relates to providing artificial tendon or ligament tissue having sufficient strength. More specifically, artificial tendon or ligament tissue having sufficient strength is provided by embedding collagen-secreting cells in a gel having strength capable of resisting a tensile load and by culturing the cells while applying a tensile load to the gel to produce artificial tendon or ligament tissue. Cells that steadily express the Mkx gene can be used as the collagen-secreting cells. A fibrin gel containing aprotinin can be used as the gel.

BONE GRAFT AND METHODS OF FABRICATION AND USE
20210106723 · 2021-04-15 ·

Provided herein is a living bone graft including a biofabricated graft core including demineralized bone matrix and a carrier and a pre-vascularized shell at least partially enrobing the graft core, the pre-vascularized shell including isolated, intact adipose-derived microvessel fragments, mesenchymal stem cells, and collagen. The disclosed bone grafts include stromal cells that differentiate and microvessels that inosculate to provide a functional microvasculature, thereby approximating native bone repair as the graft matures in the patient. Also provided herein are methods of fabricating a bespoke, living, vascularized bone graft and methods of treating a segmental bone defect in a patient.

Tissue graft

The present invention is directed to a method of producing a tissue graft, comprising at least steps of providing a gel, seeding the gel with cells of at least a first and/or cells of a second type, and culturing of the cells of the first and/or cells of the second type in said gel until the formation of at least one first biostructure in the gel by the cells of the first type and/or the cells of the second type.

METHODS AND COMPOSITIONS FOR THE TREATMENT OF WOUNDS

The methods and compositions described herein address the need in the art by providing peptides and polypeptides comprising a growth factor binding domain. In some embodiments, the peptides have an amino acid sequence that is at least 80% identical to one of SEQ ID NOS:1-7, 13-15, 49-50, or 66-70, or a fragment thereof; wherein the peptide is less than 300 amino acids in length.

IMPLANTABLE CELL DRESSING FOR TREATMENT OF DISEASE

The present invention provides a multilayer matrix comprising at least two layers in which the first layer comprises a bioresorbable material and the second layer comprises a bioadhesive material, wherein the second layer contains cells. A method for producing a multilayer matrix and the use of a multilayer matrix are also provided.

20210038762 · 2021-02-11 · ·

The present specification relates to a bioink composition for cartilage regeneration, a method for manufacturing a customized scaffold for cartilage regeneration using same, and a customized scaffold for cartilage regeneration using said manufacturing method, the bioink composition comprising: a first liquid comprising an adipose tissue-derived stromal vascular fraction, hyaline cartilage powder, and fibrinogen; and a second liquid comprising thrombin.

COMPOSITION FOR REGENERATION OF HUMAN FIBROUS CARTILAGE OR ELASTIC CARTILAGE
20210069376 · 2021-03-11 ·

The present invention relates to a composition and a kit for regeneration and treatment of cartilage, preferably, fibrous cartilage or elastic cartilage and a regeneration method using the same. A composition and a kit for cartilage regeneration according to the present invention may be administered simply in a minimally invasive manner to a site in which fibrous cartilage or elastic cartilage is needed to be regenerated or restored from injury, exhibit resistance to degradation enzymes without toxicity within the body, and are attached to or detained at and thus retained at the injured, administered site, whereby behavioral improvement may be brought about in surrounding cells, which leads to effectively inducing defected tissues of the meniscus to be regenerated. Therefore, the composition of the present invention is useful as a mediator for aiding the regeneration of biological tissue defected regions in the biomaterials field.
