Tissue engineering is done all over the world, especially in regions such as United States, Italy, and Singapore. Tissue engineering is a progressive field of biomedical technology, which utilizes a complex combination of biotechnology, tissue engineering, micro-fabrication methods, and appropriate biochemical and physical factors to re-grow, preserve, enhance, or substitute different kinds of living tissue. It also employs the concept of tissue culture in order to cultivate and grow various species of living things in a laboratory setting. This field combines cutting-edge research techniques along with state-of-the-art technology to extend the current scientific knowledge on tissue engineering and its applications.
