Abstract: The present disclosure provides a facile method for selective isolation of hyaluronan (HA) from fluids and tissues by adsorption to a solid matrix. The method involves the use of specific solvent conditions and solid phase media favoring binding and subsequent elution of HA ranging in size from about 10 kDa to several MDa, while allowing separation of HA from other biological polyanions such as nucleic acids, sulfated glycosaminoglycans, chondroitin, and heparosan.

Abstract: Provided are methods and compositions for cartilage repair. The method involves performing a surgical procedure at the site of a cartilage defect and administering a composition comprising a receptor for hyaluronan mediated motility (RHAMM)-mimetic peptide, and a high molecular weight hyaluronan.

Abstract: A HA-gelatin-pluronic hydrogel and a method for making a HA-gelatin-pluronic hydrogel are provided. The hydrogel includes hyaluronic acid, gelatin-Type A and a thermoreversible, hydrophilic non-ionic surfactant gel. The thermoreversible, hydrophilic non-ionic surfactant gel can be a poly(ethylene oxide)99-poly(propylene oxide)67-poly(ethylene oxide)99 (“Pluronic F127”). The weight ratio of HA to gelatin-Type A is between 1:2 and 2:1 and preferably about 1:1. The weight ratio of HA and gelatin-Type A to thermoreversible, hydrophilic non-ionic surfactant gel is between 1:3,000 and 1:150, preferably between 1:3,000 and 1:600 and most preferably about 1:2,400. The hydrogel is formed by combining hyaluronic acid and gelatin-Type A to form a solution, cooling the solution, mixing the solution with Pluronic F127 to form a mixture and storing the mixture at a temperature of from 25° C. to 45° C. preferably about 37° C.

Abstract: The present invention provides a biocompatible material in the form of a water insoluble cross-linked gel, which contains a stable complex of TNF-stimulated gene 6 protein (TSG-6) and hyaluronan.

Abstract: Hydrogels formed from hyaluronic acid, a nanoclay and gelatin-type A. The hyaluronic acid is preferably dissolved in a cell culture medium containing amino acids, salts, glucose, vitamins and an antibiotic to form a hyaluronic acid solution. The gelatin-type A has a weight/volume of from about 0.02% to 0.08%. The nanoclay is exfoliated in deionized water and preferably includes SiO2, MgO, Na2O and Li2O.
