Scientists find way to make human collagen in lab

Madison, Wis. Of all of the materials that make up our bodies, nothing is more ubiquitous than collagen.

It is the most important structural protein in the body, reinforcing connective tissue, bones and teeth, and forming long, fibrous cables to strengthen tendons. Collagen forms sheets of tissue that support the skin and every internal organ. There is nothing in the body, in fact......
