    摘要： Methods for treating diseased or injured tissue by implanting into the tissue at a site of the disease or injury a porous freeze-dried fibrin matrix formed from plasma proteins. The proteins include fibrinogen cleaved by the action of thrombin at varying concentrations sufficient to cleave the fibrinogen and Factor XIII. The matrix has less than 10% residual moisture and is devoid of exogenous anti-fibrinolytic agents, plasminogen and of organic chelating agents. Alternatively, the plasma proteins comprise partially purified plasma proteins that are devoid of plasminogen.

    摘要： The present invention relates to porous freeze-dried fibrin matrices substantially devoid of external anti-fibrinolytic agents, and methods of producing such matrices. Resilient matrices, also known as sponges, that are particularly beneficial for supporting three dimensional cell growth are obtained from plasma proteins substantially devoid of plasminogen or from partially purified plasma proteins, thus obviating the need for exogenous anti-fibrinolytic agents. Furthermore, incorporation of glycosaminoglycans and bioactive agents during the formation of the matrix results in a sponge having advantageous biological, mechanical and physical properties. The compositions of the present invention are useful clinically, without cells or as a cell bearing implants.
