Cell differentiation is due to the sequential regulation of gene expression. During embryonic development, cells become visibly different in structure and function as  they differentiate. The earliest changes that set a cell on a path to specialization show up only at the molecular  level. Molecular changes in the embryo drive the process, called  determination , that leads to the  observable differentiation of a cell. Once it has undergone determination, an embryonic cell is irreversibly committed to its final  fate. If a determined cell is experimentally placed in another location in the embryo, it will  differentiate as if it were in its original position. The outcome of determination—observable cell differentiation—is caused by the expression of  genes that encode tissue-specific proteins .
