Who hasn’t heard about tissue engineering? It is a method which combines cells, engineering and materials. It actually works to generate or involve the scaffold for the new formation of tissues in human body. Tissue engineering is first invented by Robert Samuel Langer Jr. It is a field where the scientist applies the methods of engineering and combines science with it in developing various biological substitutes. This substitute helps in restoring, maintain and improving the whole functioning of a human organ. It also checks the principles of the growth of the tissue. It has brought revolutionary changes in implementing the parts and strategies. This engineering of tissues has helped people to replace a whole part of the organ.
