Patent number: 7867519Abstract: A method for modifying the properties of a fibrin matrix relative to growth and ingrowth of cells, wherein for forming the fibrin matrix a fibrinogen is used consisting of a selected fibrinogen variant or a fibrinogen enriched or depleted in a selected fibrinogen variant. In particular, the use of high-molecular weight (HMW) fibrinogen leads to a fibrin having accelerated angiogenesis properties, while the use of low-molecular weight (LMW and/or LMW?) fibrinogen leads to fibrin having decelerated angiogenesis properties. The use of HMW fibrinogen when setting up angiogenesis tests results in that the tests require less time. Fibrin sealants on the basis of HMW fibrinogen can be used for burns, to promote wound healing or to inhibit scar tissue. Fibrin sealants on the basis of LMW or LMW? fibrinogen are useful to inhibit adhesions and tumor growth, for instance after surgical operations.Type: GrantFiled: April 7, 2003Date of Patent: January 11, 2011Assignee: Nederlandse Organisatie Voor Toegepast-Natuurwetenschappelijk Onderzoek TNOInventors: Monica Petronella Maria de Maat, Pieter Koolwijk
