WebThe only totipotent (capable of becoming any human cell) cells are the cells of the morula, which is the small mass of cells formed by the first few mitotic divisions after zygote formation. From the blastomeres (embryonic stem cells) onward, human stem cells are only capable of being pluripotent in their least differentiated form.
