MALAGON, Dionisio; CARDOZO, Carmen  and  GODOY, Rubén. Use of human fibrinogen in the generation of scaffold for obtaining Tissue equivalents. Rev. colomb. biotecnol [online]. 2011, vol.13, n.2, pp.243-252. ISSN 0123-3475.

Since its origin, Tissue Engineering has sought various materials that can be used for generation of scaffolds that serve to anchor, proliferation and cell differentiation leading to the production of human tissues. Many materials such as ceramic, polymeric and metal type have been evaluated to date but many have been rejected for various reasons, including its limited biocompatibility and biodegradability, immune response generated, low mechanical strength or the risk of transmission of virus or prions. Fibrinogen is a protein present in blood plasma that can be used to generate three-dimensional scaffolds that favors growth of cells, it is obtained from the patient itself, bank of blood or purified protein (Tisseel® or Tissucol®, Laboratorios Baxter). Fibrinogen acts slowing or reversing the immune response and avoiding the use of xenogeneic materials. Because the protein structure, adhesion and cell proliferation is favored with excellent results in the generation of skin equivalents, cartilage, cornea and even heart replacements in vitro and in vivo . The disadvantages presented are the rapid degradation and low mechanical strength, but in recent years it has been evaluating some biopolymer mixtures as polylactic acid (PLLA), poly-glycolic acid (PGA) and sodium alginate. This review presents some of the main applications of fibrinogen in Tissue Engineering.
