Abstract

Tissue engineering is a multidisciplinary approach to regenerate tissues by culturing cells inside three dimensional (3D) crosslinked biodegradable polymeric structures known as hydrogels. The hydrogel degrade with time and new tissue is generated. An appropriate gelation time, gel mechanical properties, pore structure, biocompatibility and degradation rate are required to successfully regenerate the tissue. Although many types of hydrogels have been produced, to regenerate a variety of tissues, producing hydrogels containing all the desirable features is still challenging. In this work we first produced in-situ forming biodegradable, injectable hydrogels from two naturally occurring polymers—chitosan (CH) and hyaluronic acid (HA), using β-...
