Dexamethasone (Dex) is commonly used in the treatment of a variety of benign and malignant conditions. Unfortunately, although it has a variety of teratogenic effects, it remains used in clinical practice for pregnant women mainly due to limited alternatives. However, there is limited knowledge of the mechanisms that lead to the observed teratogenic effects. In this study, the effects of Dex during embryogenesis on neural crest development were evaluated in the early chick embryos. First, we demonstrated that 100µL 10-6 M Dex treatment leads to craniofacial developmental defects, and also retards embryo growth and plausibly can cause embryo demise...
