In this course, students will learn about selected ex-vivo models, which are essential tools for biomedical research. The demand for ex-vivo systems, lab-on-a-chip technologies, and disease models in biomedical research is increasing as these methods address the limitations and disadvantages of traditional in-vitro systems and animal models. A key advantage of ex-vivo models is the ability to conduct tests or measurements that would be impossible or ethically unacceptable in living subjects. This includes, for example, studies on the regeneration of the brain, spinal cord, and peripheral nerve tissues, as well as the measurement of physical, thermal, electrical, mechanical, optical, and other tissue properties.
