Qingdao University 2 articles published in JoVE Developmental Biology Using Chicken Embryo as a Powerful Tool in Assessment of Developmental Cardiotoxicities Qixiao Jiang1, Xiaohui Xu1, Jamie C. DeWitt2, Yuxin Zheng1 1School of Public Health, Qingdao University, 2Department of Pharmacology & Toxicology, Brody School of Medicine, East Carolina University Chicken embryos, as a classical developmental model, are used in our lab to assess developmental cardiotoxicities following exposure to various environmental contaminants. Exposure methods and morphological/functional assessment methods established are described in this manuscript.

Here, we present a novel technique to measure whole head oxygen consumption that more closely resembles the physiological state and may aid in revealing novel drugs that modify mitochondrial activity.
