Tissue Engineering is a relatively new field that combines knowledge of engineering principles, material science and cell biology to reconstruct tissues ex vivo. It is driven by the rapidly growing need for tissue transplants world-wide. Examples of these technologies that are currently being developed in various laboratories include bioengineered skin, bone, cartilage, blood vessels, heart valves, liver, islets and bone marrow.
In this course we discuss the following topics: (i) the basic scientific principles enabling the field of tissue engineering (cell culture, biology of extracellular matrix molecules, elements of immune reaction to transplants); (ii) engineering fundamentals (biomaterials/scaffolds for tissue growth, engineering the microenvironment for optimal cell organization and function; technologies for spatio-temporal control of cell/tissue organization); (iii) methods for genetic manipulation of cells; and (iv) specific examples of bioengineered tissues including skin, blood vessels, bone and others. The ultimate goal is for the students to understand the main conceptual and technical challenges facing the field of tissue engineering and regenerative medicine and the transition of cell therapies from the laboratory to the clinic.
