From the University of Hong Kong and Hong Kong Baptist University, this study examines the effect of low exposure of a dioxin (TCDD) on embryonic stem cells. Previous animal studies had linked high dioxin exposure to susceptibility to type 2 diabetes. Results indicated altered methylation patterns in stem cell genes associated with insulin secretion. The authors suggest that early embryonic exposure to TCDD may affect pancreatogenesis.
