ABSTRACT
Dorsal-ventral axis formation in Xenopus laevis begins with a cytoplasmic rotation during the first cell cycle and culminates in a series of cell interactions and movements during gastrulation and neurulation that lead to the formation of dorsal-anterior structures. Evidence reported here indicates that mitochondria are differentially redistributed along the prospective dorsal-ventral axis as a consequence of the cortical-cytoplasmic rotation during the first cell cycle. This finding reinvigorates a possibility that has been considered for many years: asymmetries in cytoplasmic components and metabolic activities contribute to the development of morphological asymmetries.
