Definition: tissue engineering


Creating human tissue from stem cells. The first people to receive lab-grown tracheas, bladders, cartilage and skin are living proof of the benefits of this burgeoning new field. Extraordinary plans for the next several decades include the creation of complex organs such as livers, kidneys and hearts. Another tissue engineering phenomenon is the "organ on a chip," which uses live cells for drug testing (see organ on a chip). See bioprinting.
