Proposed role of microfilaments in the cell reorientation that accompanies somite formation in Xenopus.
Somite formation involves a reorientation of the cells of the paraxial mesoderm but the underlying mechanism of this movement has never been demonstrated. The present investigation shows bundles of myofibril-like material in the ventrocranial corners of some of the paraxial mesoderm cells of Xenopus prior to reorientation and consequent somite formation.
