Morphogenesis is characterized by the movements of cells and cell populations in the forming embryo. These movements apparently result from the activities of subcellular microfilaments and microtubules and are influenced by the extracellular environment. Regulation of movement may involve controlled interplay between extracellular macromolecules, microfilaments, and microtubules.
