Tissue Engineering

What is Tissue Engineering?

Tissue Engineering is an interdisciplinary and multidisciplinary field that aims at the development of biological substitutes that restore, maintain, or improve tissue function. This area is evolved from the field of biomaterials development and refers to the practice of combining scaffolds, cells, and biologically active molecules into functional tissues. The goal of tissue engineering is to assemble functional constructs that restore, maintain, or improve damaged tissues or whole organs. Artificial skin and cartilage are examples of engineered tissues that have been approved by the FDA; however, currently they have limited use in human patients.

The concept of Tissue Engineering can be understood with an example of regeneration of nerve fibres. A suitable material is chosen to form a nerve guide with a cocktail of cells and signaling molecules and is placed covering the broken nerve. Over a period of time, the functional fibres begin regenerating, filling the gap.
