Methods of producing autologous composition useful for the treatment of damaged and / or injured connective tissues, chronic tendonitis and / or chronic degenerative joint conditions, and chronic inflammatory skin diseases in mammals are described. The method comprises preparing an antiinflammatory / anticatabolic component of the autologous composition comprising il-1ra and timps. An anti-inflammatory / anticatabolic component is prepared comprising: collecting mammalian blood; blood supply to the tube; incubating the blood at a temperature from about 37 ° C to about 39 ° C for about 24 hours preferably in the presence of sodium citrate; centrifuging blood to separate blood into a supernatant component and a cell fraction; collection of the supernatant component. the method further comprises the step of preparing a regenerating component of an autologous composition comprising collecting mammalian blood; blood supply to a tube in the presence of about 4% citric acid; centrifuging blood to separate a planet-rich plasma component from whole blood; collecting the platelet rich plasma component and mixing the supernatant component with the platelet rich plasma component to provide the autologous composition. Also provided is a method for treating damaged and / or injured connective tissues, chronic tendinosis, chronic muscle injuries and / or degenerative joint conditions, and inflammatory skin diseases in an individual with the autologous composition, an autologous composition for treating damaged and / or connective tissue. / or injured, chronic tendinosis, chronic muscle injuries and / or chronic degenerative joint conditions and inflammatory skin conditions in a mammal and the use of autologous composition for the treatment of damaged and / or injured connective tissues, chronic tendinosis, chronic muscle injuries and / or chronic degenerative joint conditions and inflammatory skin conditions in a mammal.são descritos métodos de produção de composição autóloga útil
