Could a hidden network within our bodies hold clues to how cancer spreads and diseases develop?
Rebecca G. Wells, Professor in Medicine with a secondary appointment in Bioengineering, is helping uncover the mysteries of the interstitium, an intricate network of fluid-filled spaces connecting tissues and organs throughout the body.
Alongside Neil Theise of New York University and fellow researchers, Wells is challenging long-held assumptions about human anatomy and opening new avenues for understanding how diseases move through the body.
Why does this matter? Understanding these pathways could one day help physicians detect diseases earlier, better understand cancer progression and develop more effective treatments.
Discover how this research is reshaping our understanding of the human body in a fascinating new feature from The Pennsylvania Gazette.

The discovery of a circulatory system called the interstitium that operates “in between” the lymphatic and cardiovascular systems has profound implications for the diagnosis and treatment of many conditions—and may forge new links between Western, Eastern, and other traditional medicines.
