WebAt first, cells may be specified, earmarked for a certain fate but able to switch given the right cues. Next, they may become determined, meaning that they are irreversibly committed to a certain fate. Once a cell is determined, even if it’s moved to a new environment, it will differentiate as the cell type to which it's become committed ^5 5.
