Short YouTube talk by Joy Kong, MD (uploaded Oct 7, 2024) highlighting risks of embryonic stem cells and induced pluripotent stem cells. The speaker emphasizes the risk of uncontrolled tumor formation (teratoma), potential oncogenic risks from viral vectors used to modify cells, and genetic mismatch concerns because embryonic stem cells derive from embryos rather than the recipient.
Overseas, you could do embryonic stem cells. But those cells carry certain risks, which is the potential of forming new cancer, new tumor. So embryonic stem cells has that potential and induced pluripotent stem cells. It can cause this uncontrolled cancer growth, which is called teratoma. And of course, there are other risks too, because they use viral vectors to change the cells. And there were also other concerns because of the viral factor. So there are different concerns with these different types. Embryonic stem cells is from an embryo, right? That's not from any existing human being. So that will be different from the recipient. So the genetic makeup will be different. But again, I think the biggest concern is the teratoma formation.
