RESEARCH INTERESTS

Embryonic stem cells are derived from the inner cell mass of blastocysts and can differentiate into any of over 200 cells in the body. Because of their origin and their ability to differentiate, embryonic stem cells provide valuable models for studying the effects of environmental chemicals on prenatal stages of development. As humans, we are more sensitive to environmental toxicants during prenatal development than at any other time in the life cycle. Our lab is currently using mouse and human embryonic stem cells to investigate the effects of environmental toxicants on early mammalian development.

We have recently used mouse embryonic stem cells (mESC) to study the effect of various types of cigarette smoke on cellular processes in stem cells. This study compared conventional and harm reduction products as well as mainstream and sidestream smoke. Mainstream smoke is inhaled by active smokers while sidestream smoke burns off the cigarette and is the major component of secondhand smoke or environmental tobacco smoke. Our first study with mESC showed that important biological processes such as cell-to-matrix attachment and proliferation are inhibited by smoke solutions from both conventional and harm reduction products. Moreover, MS and SS from harm reduction brands were usually more potent than smoke from the conventional brand. This unexpected result emphasizes the need to examine harm reduction products carefully and to fully access their safety before implementing their widespread use in tobacco control programs.

We are currently extending these experiments to human embryonic stem cells and developing assays to directly interrogate hESC with various types of tobacco products and other environmental chemicals.
