Scientists Make Teeth Using Urine
(NEW YORK) -- A team of scientists at the Guangzhou Institutes of Biomedicine and Health have taken inspiration from urine. Duanqing Pei, a professor of stem cell biology at the research institute, took epithelial cells found in urine and converted them into teeth. "We have a long-running interest in tooth formation," Pei told ABC News. "We want to use somebody's own cells to generate a tooth."
