The blastocyst is a lot of things, but 'undifferentiated' isn't one of them. But you probably knew that already and chose to use the term to support only the notion of totipotent to pluripotent cell differentiation. The very act of reaching the blastocyst age of the individual human life conceived shows some differentiation in order to polarize the cell structures for placental formation and body formation. Therapeutic cloning is the act of conceiving an individual close duplicate to the parent genetic donor, then raising that individual life toi the stage desired for harvesting. That is cannibalizing of individual human life.

... and many of us don't want the government throwing up obstacles to their research. Furtive plea of the modern cannibal.

The blastocyst is a lot of things, but 'undifferentiated' isn't one of them.

It contains two types of cells, but only one of those is destined to become part of the fetus -- the other will form the placenta. So at the blastocyst stage, all the cells which develop into the fetus are undifferentiated.
