Tissue engineering is a field that involves the development and application of techniques to create functional substitutes for damaged or diseased tissues, with the goal of restoring normal function. This interdisciplinary approach combines knowledge from biology, chemistry, materials science, and engineering to develop biocompatible scaffolds and growth factors that can stimulate cell growth and regeneration in a controlled environment. The ultimate aim is to improve patient outcomes by providing new tissues or organs for transplantation, as well as developing therapies for chronic conditions such as diabetes or heart disease.
