* Due to ethical concerns scientists looked for an alternative way to gain human pluripotent cells. Some people argue that separating human embryonic stem cells is equal to a kill: to them it matters the cells' potential to become a complete human. Other people don't have concerns about this because the embryonic stem cells would be separated before neurons and a possible personality form. -- With the new methods, mature cells become reprogrammed to so-called [[wikipedia:Induced_pluripotent_stem_cells|induced pluripotent stem cells (iPSC)]]. Those cells - which are very similar to ESC - can then be prompted to differentiate again into the desired cell types.

* Producing those pluripotent cells and let them transform (differentiate) into the desired cell types is only the second best option because errors can occur during the process and often there are more than one transformation necessary.
