The Wake Forest Institute for Regenerative Medicine (WFIRM) is the recipient of a major research funding award from the U.S. Department of Health and Human Services (HHS) to support its lung-on-a-chip technology as a model to develop chemical injury treatments.
The five-year $24 million program has been approved with an initial contracting commitment of $13.5 million for the first 2 years.

Specifically, the funding from the Biomedical Advanced Research and Development Authority (BARDA), part of the HHS Office of the Assistant Secretary for Preparedness and Response, awarded over a five-year period, will validate how WFIRM’s lung-on-a-chip technology works in modeling the effects of chlorine gas - deemed a potential national security threat - on human lungs and to develop treatments.
Currently, the study of respiratory health, disease and biomedical interventions is primarily performed in animal models or 2D cell culture models using human or animal cells. This funding will help the WFIRM research team advance the development of its micro-tissue engineered lung organ tissue equivalent platform. This model can be engineered to reflect both normal and diseased tissue and includes innate immune system responsiveness, and accurate and reproducible response to drugs and toxins.
“Our lung-on-a-chip technology has grown out of our body-on-a-chip research, a system of miniature human organs created in the laboratory that can be used to further our understanding of the effects of inhaled chlorine gas and other toxins, as well as potential treatments,” said WFIRM Director, Anthony Atala, M.D.
WFIRM experts in regenerative medicine will work with Precision Medicine colleagues with expertise in genomics to identify the effects of chlorine gas and other toxic agents on the lungs and to determine the usefulness of the organoid in developing treatments for the resulting lung injuries.
According to BARDA, chlorine gas was used as a weapon during World War I and has been used repeatedly during the ongoing Syrian civil war. In addition, the amount of chlorine manufactured, along with its ready availability, makes this chemical a potential national security threat to the United States. Further, chlorine is one of the most-used industrial gases in the United States and causes multiple deaths and injuries due to accidents. In 2005, a train accident in Graniteville, South Carolina caused a tank car containing chlorine gas to leak, causing nine deaths and at least 250 injuries.
How Lung-on-a-Platform Works
The lung-on-a-chip platform is part of WFIRM’s overall Body-on-a-Chip program, a miniaturized system of human organs that can model the body’s response to harmful agents, can test the effects of new agents during drug discovery, or can help to develop potential therapies. The system can also be used for personalized medicine; for example, it can screen chemotherapy agents on a patient’s own cancer, so the most effective treatment can be given from the start. The Body-on-a-chip system overcomes the substantial limitations of animal models and 2D cell culture models for studying mechanisms of disease and treatment efficacy.
