Bone grafts and constructs including stem cells are provided. Example bone grafts include osteogenic stem cells seeded on a scaffold of osteoconductive cortico-cancellous chips and/or osteoinductive demineralized bone. Example constructs include extracellular matrix on a synthetic scaffold, in which the ECM is secreted from MSCs seeded onto the synthetic scaffold. Also provided are methods of making the present bone grafts and scaffolds. Further provided are methods of promoting bone healing and treating wound healing, by administering the present bone grafts and constructs to a mammal in need thereof Also provided are kits that include the present bone grafts and/or constructs, or components thereof.

Bone void filler compositions and methods for preparation to provide substrates with carbonate surface coatings to promote bone growth.

Terminally sterilized demineralized bone material (DBM) and systems and methods for protecting DBM against damage caused by terminal irradiation are described. A method includes providing the DBM, which includes at least a collagen matrix and natural, non-collagenous protein. The DBM is soaked in a mixture of glycerol and a solvent to remove and replace water in the collagen matrix of the DBM. The DBM is dried, after soaking, to form a protected DBM.

Described herein are bisphosphonate oxazolidinone compounds, and conjugates and pharmaceutical formulations thereof, that can include a bisphosphonate and an oxazolidinone (or an oxazolidinone antimicrobial or antibiotic agent, substituent or derivative thereof), where the oxazolidinone can be releasably coupled to the bisphosphonate. Also provided herein are methods of making and methods of using the bisphosphonate oxazolidinone compounds, conjugates and pharmaceutical formulations thereof. Also provided herein are methods of use of the compounds, conjugates and formulations for treating a bone disease or for use in preparing a formulation for the treatment a bone disease.

Provided herein is a bone repair composition that is composed of periosteum containing an angiogenic growth factor(s), cancellous bone chips containing viable osteogenic cells, and, optionally, demineralized bone matrix (DBM) chips. Also provided herein are articles of manufacture and methods of use thereof to treat bone defects.

Disclosed are methods of lyophilizing a tissue sample comprising obtaining a tissue sample, contacting the tissue sample with a lyoprotectant solution, freezing the tissue sample, performing a first drying step of the tissue sample after freezing, and performing a second drying step of the tissue sample after the first drying step. Disclosed are lyophilized tissues prepared using the disclosed methods of lyophilizing a tissue sample comprising obtaining a tissue sample, contacting the tissue sample with a lyoprotectant solution, freezing the tissue sample, performing a first drying step of the tissue sample after freezing, and performing a second drying step of the tissue sample after the first drying step. Disclosed are methods of treating a wound or tissue defect comprising administering a reconstituted lyophilized tissue to the wound or tissue defect.

The invention provides a new method of synthesizing cross-linked hyaluronic acids, compositions thereof, tubes and syringes containing such compositions alone or in combination with PRP/BMC, new devices for PRP/BMC preparation, and uses thereof in cell culture, skincare and joint preservation. The invention provides a method for the production of a crosslinked gel (preferably of desired molecular weight and/or concentration) from at least one first polymer (preferably hyaluronic acid), comprising the steps of: homogenizing said first polymer, hydrating said first polymer in a basic solution, crosslinking said basic solution by adding at the least one crosslinking agent at a higher temperature than room temperature, neutralizing said basic solution in an acidic solution, homogenizing said solution, mixing said solution with a supplemental quantity of a second polymer (preferably a second polymer of substantially the same molecular weight and/or concentration as said first polymer), and purifying said solution.

The present invention is directed to a device for the growth of new bone or bone-like tissue under in vitro cell culture conditions.

Methods of forming a connective tissue-to-bone interface scaffolds (e.g., ligament-to-bone interface scaffolds, tendon-to-bone interface scaffolds, etc.). These scaffolds (grafts) may be formed from in such a way as to provide both a mineralized and demineralized layer in which the entire graft is flexible, compressible and compliant.

This invention provides porated cartilage products and methods of producing porated cartilage products. Optionally, the cartilage products are sized, porated, and digested to provide a flexible cartilage product. Optionally, the cartilage products comprise viable chondrocytes, bioactive factors such as chondrogenic factors, and a collagen type II matrix. Optionally, the cartilage products are non-immunogenic.
