Abstract

Tese de Doutoramento em Ciência e Tecnologia de Materiais - Engenharia de Tecidos - Materiais HíbridosA number of natural origin polymers are being employed in tissue engineering strategies. Natural origin polymers offer the advantage of being similar to macromolecular substances, which the biological environment is prepared to recognize and to deal with metabolically. Another attractive characteristic of natural polymers is their ability to be degraded by naturally occurring enzymes, implying that the implant will be degraded and eventually metabolized by physiological mechanisms. Chitosan, a mucopolysaccharide, is the alkaline deactylated product of chitin and has structural similarities to glycosaminoglycans, thus, mimicking their ...
