Aliphatic Chain Modification of Collagen Type I: Development of Elastomeric, Compliant, and Suturable Scaffolds.

Collagen type I is one of the most suitable natural biomaterials for constructing tissue-engineering scaffolds. Despite their biocompositional similarities to physiological tissues, these scaffolds lack host specific and matching mechanical properties. While it is possible to enhance their stiffness by cross-linking, it often compromises their abilities to expand or strain under minimal stress, that is, compliance (inverse of stiffness).

Tissue-Engineered Neo-Urinary Conduit from Decellularized Trachea.

Decellularized tissues have been increasingly popular for constructing scaffolds for tissue engineering applications due to their beneficial biological compositions and mechanical properties. It is therefore natural to consider decellularized trachea for construction of tissue-engineered trachea, as well as other tubular organs. A Neo-Urinary Conduit (NUC) is such a tubular organ that works as a passage for urine removal in bladder cancer patients who need a urinary diversion after their diseased bladder is removed.
