Here's the thing.
A stem cell is a cell that is "equipotent", it can be come anything.
An identical twin is where an embryo breaks off some of its stem cells, and they grow into a copy of the original person.
A stem cell is potentially an embryo. So if its a problem to harvest stem cells from embryos, technically, it shoudl be a problem to use stem cells,
period. Any of them could, with the proper care, become a person.
I don't see it as a problem, but I think that the objectors to embryo harvesting, and using embryonically derived stem cell lines, should consider
ITs an emotive issue, not a rational one. Rationally, any stem cell is a potential person, and it doesn't matter if it was embryonically derived.
