If cells are transplanted from their normal region in an embryo to a different region in a recipient embryo, such cells will alter their fate, but not their specification
Cell fate describes the allocation of cells to the germ layers, ectoderm, mesoderm, or endoderm, whereas specification describes the exact tissues that each cell will ultimately become
The fate map of an embryo does not change during development -- the fate map of an egg is the same as the fate map of a late blastula -- whereas the specification map of an embryo changes continually as the embryo's development proceeds
The fate of a cell is determined by labelling that cell and following it during normal development, whereas the specification state of a cell is determined by culturing a cell in an artificial medium and observing what tissues form from it
