Compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.

Described are osteogenic paste compositions with enhanced osteoinductive properties for use in bone repair. Compositions comprising a quickly resorbable paste carrier, a more slowly resorbed mineral matrix, and Bone Morphogenetic Protein (BMP) or other osteogenic factor are described which enable increased osteoinductive activity while retaining a reliable scaffold for the formation of new bone at the implant site. Methods for making and methods for therapeutic use of the compositions are also disclosed.

The invention is a medical implantable device which is coated by the method according to the invention. The surface of the substrate used for the implantable device, in the raw condition, following a cleaning regime and physiochemical pretreatments, is coated using a biomimetic process in a supersaturated calcium phosphate solution (SCPS) to obtain the desired coating coverage and morphology maintaining a ratio of calcium to phosphorus pH, as well as solution temperature plays a major role in yielding precipitation of the proper phase of CaP so that composition, morphologies, crystal structures, and solubility characteristics are optimal for the deposition process. The biomimetic coating adds the attribute of osteoconductivity to the implant device. To maximize bone growth, the implant must also induce bone growth, or possess the attribute of osteoinductivity. This attribute is acquired by the use of therapeutic agents, i.e. bone morphogenic proteins (BMP), growth factors, stem cells, etc. The preparation of the SCPS solution is slightly altered so that during the immersion of the implant in the SCPS, the therapeutic agents are co-precipitated and bonded with the CaP directly on the underlying surface of the implant device. A final dipping process into a BMP solution provides an initial burst of cellular activity. For delivering stem and/or progenitor cell, after drying the dipped solution of BMP, the cells are cultured on the surface of the implant.

A novel class or family of TGF-β binding proteins is disclosed. Also disclosed are assays for selecting molecules for increasing bone mineralization and methods for utilizing such molecules. In particular, compositions and methods relating to antibodies that specifically bind to TGF-beta binding proteins are provided. These methods and compositions relate to altering bone mineral density by interfering with the interaction between a TGF-beta binding protein sclerostin and a TGF-beta superfamily member, particularly a bone morphogenic protein. Increasing bone mineral density has uses in diseases and conditions in which low bone mineral density typifies the condition, such as osteopenia, osteoporosis, and bone fractures.

The invention relates to a method for culturing epithelial stem cells, isolated tissue fragments comprising the epithelial stem cells, or adenoma cells, and culturing the cells or fragments in the presence of a Bone Morphogenetic Protein (BMP) inhibitor, a mitogenic growth factor, and a Wnt agonist when culturing epithelial stem cells and isolated tissue fragments. The invention further relates to a cell culture medium comprising a BMP inhibitor, a mitogenic growth factor, and a Wnt agonist, to the use of the culture medium, and to crypt-villus organoids, gastric organoids and pancreatic organoids that are formed in the culture medium.

A cage for facilitating fusion of bones, such as vertebrae, or fusion of adjacent bone surfaces is disclosed. In one form, the cage includes a plurality of spaced apart walls comprising a biodegradable polymeric material (e.g., polycaprolactone); an osteoconductive mineral coating (e.g., a calcium compound) on at least a portion of the walls; and a bioactive agent (e.g., a bone morphogenetic protein) associated with the polymeric material and/or the coating. The bioactive agent is present in amount that induces ossification between the bones or adjacent bone surfaces. The cage may also include a fixation plate connected to at least one of the walls.

A method and apparatus for preparing a bone graft composite using an infusion chamber. A modular tube having a porous material contained therein and having removable end caps is provided. Bone marrow aspirate or other bone morphogenic protein containing suspensions may be infused into the tube. A filter on one end of the tube prevents the fluid from escaping while permitting air to be expelled from the tube as it is filled with bone marrow aspirate. Once infused into the tube, the bone marrow aspirate is allowed to settle to a putty or paste-like consistency, the putty and material together forming a bone graft composite.
