Researchers study how chemicals in drugs and around us impact stem cells
Date:1/17/2012

Troy, N.Y. Chemicals in pharmaceutical drugs can obviously save lives. But as more and stronger chemicals have been introduced, our basic knowledge of the broader health impact of all these chemicals has not kept up with the rapid pace of innovation. There is exceptionally little information on how chemicals in our drugs and also in the environment around us, including on the food we eat, impact some of the most important cells in our body: stem cells. Without basic knowledge and tests on the impact of chemicals on our stem cells, we may be unwittingly damaging essential regenerative functions in our body.

Bioengineers at Rensselaer Polytechnic Institute and the University of California, Berkeley, have been awarded a more than $2 million grant from the National Institutes of Health (NIH) to study how chemicals in drugs and our environment impact our stem cells.

Leading the research effort for Rensselaer is Jonathan Dordick, director of the Center for Biotechnology and Interdisciplinary Studies (CBIS) and the Howard P. Isermann '42 Professor of Chemical and Biological Engineering. Dordick is co-principal investigator on the grant with David Schaffer, professor of chemical and biomolecular engineering and co-director of the Berkeley Stem Cell Center at the University of California, Berkeley.

The researchers hypothesize that stem cells, which are essential for the replacement of dead and damaged tissues in the body, react in fundamentally different ways to chemicals than other cells in the body. The grant will allow them to study the impacts of known chemical compounds on adult stem cells, providing the most substantive information to date on how many of the chemicals used every day around the world in drugs, pesticides, and other products impact stem cells. The work also will seek to develop a new predictive safety screening tool that manufacturers can use to test the toxicity of new chemical compounds on stem cells before their dru
