* 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. | * Due to ethical concerns scientists looked for an alternative way to gain human pluripotent cells.
