Claudio Daniel Stern

Expert on the biology of early embryonic development. Discovered how the nervous system becomes segmented because nerves are confined to one half of each neighboring somite due to the inhibitory properties of the other half. Provided direct cell lineage evidence for endogenous stem cells that divide asymmetrically in the embryo and give rise to the notochord and somites. With Tabin and Kuehn, identified the first four genes controlling left-right asymmetry in the body plan. Uncovered molecular mechanisms responsible for setting up avian embryo polarity and prevent twinning, and key signals that direct cell movements during gastrulation. Also investigating spatial and temporal aspects of the induction and regionalization of the central nervous system. These studies highlight the importance of timing in developmental decisions. Native of Uruguay, Stern has fostered the promotion of international scientific exchanges, particularly with Latin America. President, International Society for Developmental Biologists (2010-2014).
