seen research change course with administrations. For instance, George W. Bush decided that only research on embryos derived before August 9, 2001 could be used to create stem cell lines. Subsequently, President Barack Obama issued an executive order reversing this and encouraging the National Institutes of Health to pay for embryonic stem-cell research, so long as federal money wasn’t used to directly make the stem cells. (NIH) New breakthroughs are providing hope and may soon make this debate less relevant. Scientists have learned how to stimulate a patient's own adult cells to behave like embryonic stem cells. These so-called induced pluripotent stem cells are reducing the need for human embryos in research (NIF). Both human embryonic stem cells and induced pluripotent stem cells are pluripotent: they can become any type of cell in the body. But ethical questions regarding stem cells research may not entirely go away. An additional ethical consideration is that induced

cells have the potential to develop into a human embryo, in effect producing a clone of the donor. Currently, the consensus is cloning is immoral and illegal. (NIH) Inevitably, some human embryos will still be needed for research. These induced cells are not exactly the same as embryonic cells. Embryonic cells provide important controls: they are a gold standard against which the induced stem cells are measured Predictably, controlling cell proliferation and differentiation requires additional research and we need to continue the study of

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
