Advancements in Tissue Engineering

Advances in tissue engineering have introduced a number of promising ways to repair large bone defects. To date, the techniques used in these efforts included autografts and allografts. These methods have serious limitations and associated risks, thus promoting research efforts to find more effective treatments. Tissue engineering uses methods from material engineering and life sciences to design alternative devices with similar morphology and function to damaged tissue resulting in tissue repair.

Strong development of interdisciplinary fields in tissue engineering has created a new set of organizational alternative parts and implementation strategies. Scientific advances in biomaterials, stem cells, growth and differentiation factors, and biomimetic environments provide a unique opportunity to create tissue in the laboratory by combining artificial extracellular matrix ("scaffold"), cells and bioactive molecules It produced. The main challenges facing today's tissue engineering are more complex functions, as well as functional and biomechanical stability in experimental cultures for transplantation and the need for angiogenesis. The ongoing success of tissue engineering, and the ultimate development of true human replacement parts, is the result of progress in engineering and basic research from tissue, matrix, growth factors, stem cells and developmental biology, and materials science and biology It is fusion.

Tissue engineering is the use of cellular, engineering, and materials methods, as well as combinations of suitable biochemical and physicochemical factors to improve or replace biological tissue. Tissue engineering involves the use of tissue scaffolds to form new biological tissues for medical purposes. It has been classified as a subarea of ​​biological material, but as its scope and importance increases it can be regarded as an independent field. Although the definition of the majority of tissue engineering covers a wide range of applications, in practice this term is closely related to the use of repair or replacement of a part or whole tissue (ie bone, cartilage, blood vessel, bladder, skin, muscle, etc.) . In many cases, the organizations involved require specific mechanical and structural characteristics to function properly. This term also applies to efforts to use manually created cells within the support system for specific biochemical functions (see, for example,

The field of tissue engineering, science includes the development of biological substitutes that can replace human diseases and damaged tissues. The term tissue engineering was introduced in the late 1980s. By the early 1990s, the application of engineering to the concept of biological tissue repair led to the rapid development of tissue engineering as an interdisciplinary field that could bring revolution into important areas of medicine. Tissue engineering combines biological factors such as cells and growth factors with engineering principles and synthetic materials. Alternative tissues can be created by first inoculating human cells into a scaffold that can be made of collagen or a biodegradable polymer. The scaffold is then incubated in a medium containing growth factors that stimulate cell proliferation and division. When the cells spread on the scaffold substitute tissue
