The Stem Cell Debate Heats Up

Here's a great review about those new "induced pleuripotent stem cells" (iPS) we've been hearing about. iPS's are truly "patient specific stem cells" since they come from the patient himself or herself. The cells are manipulated in the lab, using viral particles and specific environments to make the able to become many different types of cells.

It would be very difficult, in my opinion, to make these cells become embryos, with all the structures that would allow them to function as individual organisms. From what I understand, the cells return to a state that allows them to become tissues with several different types of cells and cell groups, but they are never organized.

In my opinion (again), the induction process can't be more of a problem than the risk of immune rejection and the manipulations that embryos derived from In Vitro fertilization go through or the changes that are bound to be inherent with cloned cells derived through Somatic Cell Nuclear Transfer. On the other hand, volunteers and tissue samples for IPC experiments ought to be abundant.

And no one has to die for it.

30 years: In Vitro Fertilization,Bioethics and Public Health

My own first child is a little older than Louise Brown, the first child born from in vitro fertilization (IVF). This incidental pioneer celebrates her 30th birthday this month, calling for reviews and editorials on what her birth has meant to culture and to individuals, such as this one from the UK's Telegraph.

It's good to hear that Ms. Brown has a child of her own, "naturally conceived" with her husband. Full circle.
