“We have also learned that this cell line, which has long been assumed to have been derived from the tissue of an aborted child may, in fact, have been derived from the tissue of a miscarried, or ‘spontaneously aborted,’ child. Why did we long believe the cell line to be abortion derived? The simple answer is that Frank Graham, the scientist who first derived the cell line, had always simply assumed that the tissue on which he worked had been derived from an elective abortion.
“He was not involved in the abortion, nor the procurement of the tissue. But he judged that the fetus was in good health at the time of its death, which makes abortion more likely than miscarriage, and he worked in a context where using the human remains of aborted children was not uncommon.”
Back in 1973. So it is thousands of times removed in any case.
That's pretty thin gruel.
