The Sweetness of Embryonic Elongation and Differentiation

Metabolic pathways play a vital yet poorly understood role in embryogenesis. In this issue of Developmental Cell, Bulusu et al. (2017) and Oginuma et al. (2017) provide insights into the intricate relationship between metabolism and morphogenesis, showing that glycolysis facilitates body elongation and balances neural and mesodermal differentiation. © 2017 Elsevier Inc.
