  • Publication number: 20230358730
    Abstract: An exemplary embodiment of the present disclosure provides a composition comprising two or more cytokines, and one or more of keratan sulfate, chondroitin sulfate, or hyaluronic acid. The composition can simulate a fluid from a patient. The simulated fluid has a viscosity, a storage modulus, and a loss modulus similar to that of patient-derived synovial fluid. A method for making a composition for simulating a fluid from a patient is also disclosed. The method includes creating a mixture comprising two or more cytokines, and one or more of keratan sulfate, chondroitin sulfate, or human serum albumin. The method also includes adding a low molecular weight hyaluronic acid to the mixture, adding a high molecular weight hyaluronic acid to the mixture, and incubating the mixture for a predetermined time at a temperature ranging from approximately 0° C. to approximately 10° C.
