Biomimetic Poly(Ester Amide) Biomaterials For Vascular Tissue Engineering, Darryl K. Knight

Electronic Thesis and Dissertation Repository

The focus of this research was to develop a biomimetic, degradable vascular scaffold that could be considered as part of a tissue-engineered vascular graft strategy. A family of degradable poly(ester amide)s (PEAs) derived from naturally occurring α-amino acids, aliphatic diols and diacids were synthesized to yield PEAs with glass transition temperatures below physiologic temperature ensuring their pliability. Tri-functional amino acids l-lysine or l-aspartic acid were incorporated into the polymer backbone yielding complementary functional handles for subsequent conjugation of growth factors. Higher molecular weight PEAs were obtained using an interfacial polycondensation technique compared with a solution polymerization approach.
