    What stiffening lung tissue reveals about the earliest stages of fibrosis

    A Penn Engineering team has targeted the lung’s extracellular matrix to better understand early fibrosis by triggering the formation of special chemical bonds that increase tissue stiffness in specific locations, mimicking the first physical changes that may lead to lung fibrosis.
