Tissue engineering is now defined as an interdisciplinary field that combines engineering and life science ideas to the development of biological substitutes that restore, maintain, or improve tissue function or the function of an entire organ. Tissue engineering scaffolds are made to change the physical, chemical, and biological environment in which cells live. Tissue engineering/regenerative medicine strategies necessitate the interaction and integration of suitable physical and biological signals with tissue and cells. As a result, modifying variables such physiologically active proteins and DNA are essential for success.
Regenerative medicine is a broad term that refers to a variety of techniques that use cells or tissues as therapeutic tools to rebuild or repair damaged or diseased structures and restore function. Regenerative medicine has the ability to repair or replace tissues and organs that have been destroyed by age, disease, or trauma, as well as to correct congenital flaws. The area of regenerative medicine comprises a wide range of strategies, including the use of materials and de novo produced cells, as well as various combinations of these, to replace missing tissue, both architecturally and functionally, or to aid tissue recovery. Stem cell therapy to encourage tissue repair and regeneration at the site of injury, as well as the transplantation of tissues or organs grown or manufactured outside the body, are examples of regenerative medicine treatments.
