A look at one of the faces behind tissue engineering research is in the New York Times: "We are the people interested in building living systems in humans and animals called the tissue. We start with the basic building blocks of these systems, which are cells or different proteins or molecules, and then we reassemble them into something that becomes living tissues within a body. The promises of tissue engineering are many. In trying to regenerate cartilage, we're very far along. In terms of progress, things related to our cartilage, bones, skin, we're likely to see products within 5 to 10 years. The really big impact areas - treatments for Parkinson's disease and diabetes - those will happen later, within my lifetime."
