iPSCs are often seen as an alternative to embryonic stem cells, and some studies have even called the two indistinguishable. I don't think they're totally indistinguishable though. I've heard that iPSCs retain some DNA methylation that's characteristic of the cell types that they were derived from, but I don't think that nullifies their potential (though my opinions should obviously be taken with a large grain of salt since I'm not very well-read, lol). It's also possible to express the genes that are used to generate iPSCs within a living organism but stop before the cells lose their cell type and become iPSCs, and it really does seem to unlock at least some regenerative ability, however there's obviously the risk of going to far and I don't think it has as much potential as tissue replacement. Though the results seem similar to fetal wound healing ability.ipsc’s are an interesting topic with lots of potential but i would disagree with any of this research being conducted with stem cells from aborted fetal tissue vs the plethora of other options.
