if it turns them into embryonic stem cells, I don’t see how that solves any ethical dilemma.
If the doctors succeeded in getting an actual embryo that way, there would be a moral pickle. But this does not sound like son of Frankenstein. All they did was fiddle around with a skin cell in order to get a cell which is an exact mimic of one taken from some hapless embryo that would have had to be killed in the process of getting it.
This process turns adult cells into the functional equivalent of embryonic stem cells without the necessity of destroying an embryo. Since no embryos are destroyed, there's no ethical dilemma involved.
Perhaps because the source isn't a dead baby??? Scraping a few cells off your epidermis isn't in the same league as deliberately creating and destroying a fetus.
As long as the cells can not develop into an embryo, there should not be a moral difficulty. They may be able to develop into differentiated tissue in the right environment with the right signals, but still be unable to direct their own developmental path that would make them a complete organism - a human bein.
