2012 (Engelska)Ingår i: Type I collagen: biological functions, synthesis & medicinal applications / [ed] Maria Eduarda Henriques and Marcio Pinto, Nova Science Publishers, Inc., 2012, s. 1-43Kapitel i bok, del av antologi (Övrigt vetenskapligt)
Abstract [en]

It is now recognized that biological macromolecules such as components of the extracellular matrix (ECM) are important as instructive templates in Regenerative Medicine applications. They are now increasingly used in the development of a new generation of bio-mimetic materials that allow for restoration of function when the self-renewal capacity of a tissue or organ cannot overcome degeneration caused by disease, injury or age-related wear. For example, macromolecules derived from connective tissue have been isolated, chemically modified, and used in medical applications ranging from tissue repair and reconstruction to drug and cell delivery systems. Common ECM macromolecules of vertebrates include collagen, proteoglycans, elastin, and other cell-interactive proteins such as fibronectin and laminin. Of these, type I collagen is the most abundant ECM macromolecule and is the primary scaffolding material that maintains the 3-dimensional structure of tissues and organs within the body. It also provides the micro-environmental milieu for cellular attachment, migration, and proliferation.

Animal-derived collagen is frequently used in tissue engineering applications due to its biocompatibility, but there are significant concerns about the immunogenicity of xenogeneic material as well as the possibility of pathogen transmission. Most recently, synthetic collagens and recombinant human collagens have been produced for medical application. Regardless of the source, however, macromolecules require processing and chemical treatment in order to improve their stability both in vitro and in vivo. This is most commonly achieved by cross-linking using a variety of agents. Cross-linking also allows for the development of “tailor-made” collagen-based biomaterials that possess specific properties for tissue engineering. Chemical cross-linkers such as glutaraldehyde and epoxy compounds are frequently used but their cytotoxicities have limited their clinical application. This has led to the use of zero-length cross-linkers such as carbodiimides and naturally derived agents such as genipin. Enzymatic cross-linking is becoming an attractive method to induce in situ biomaterial formation due to the mildness of the reaction. Naturally occurring enzymes such as transglutaminase are now commonly used. Photosensitizers used in combination with ultra-violet light irradiation can be used as exogenous cross-linkers. For example, riboflavin in combination with ultra-violet light is used clinically to augment the properties of collagen-based tissues such as the sclera and the cornea.

Collagen type I is a good candidate for tissue engineering and in vivo delivery systems for cells, proteins, and drugs. Important to its versatile and functional nature are its chemotactic properties, which promote cellular proliferation and differentiation, richness in cross-linking sites, and biodegradability. Collagen based delivery matrices have been reported to improve the results of cell delivery by improving cell viability.
