34,36] Stem cells are classified according to their potency, where the hierarchic ordering ranges from totipotency (zygote and its offspring cells of the morula) to pluripotency (embryonic stem cells and embryonic germ cells) and multi-potency (haematopoietic and mesenchymal stem cells).
These changes in gene expression related transcriptional machinery, chromatin structure and the other cellular functions occurring during several cleavage stages are expected result in a unique chromatin structure capable of maintaining totipotency during embryogenesis and leading to differentiation during the postimplantation development.
Crucial to this approach is discovering a way to reverse cell differentiation all the way to pluripotency, but not (as in cloning) even further back to totipotency.
