UPI (Dec. 20) -- Researchers at the U. of I. have created a new technology to track tumor development within human breast tissue. “We believe that capturing the dynamic cellular and molecular features in freshly removed or biopsied tissue specimens contains valuable diagnostic and prognostic information that is currently lost when specimens are placed in a fixative and essentially killed quickly in order to preserve structure,” says Stephen Boppart, a professor of bioengineering at Illinois.
