Alan Osborne Trounson is a scientist from Australia who studies embryology and stem cells. His research has improved the success rates of in vitro fertilization, or IVF. IVF is a medical procedure in which scientists fertilize an egg cell with sperm outside of the body, often in a laboratory petri dish, then transfer the fertilized egg to a woman’s uterus to start pregnancy. Trounson also researched embryonic stem cells, or stem cells collected from embryos, and their potential for treating injuries and diseases. Additionally, Trounson led the Californian Institute for Regenerative Medicine, or CIRM, one of the largest agencies to fund stem cell research in California, from 2007 to 2014. Over the course of his career, Trounson developed several techniques that improved the effectiveness of IVF, including fertility treatments and cryopreservation, and supported stem cell research as a scientist and administrator.
In 1999, John Ancona Robertson, a researcher who studied bioethics and law, published “Ethics and Policy in Embryonic Stem Cell Research,” hereafter “Ethics and Policy,” in the Kennedy Institute of Ethics Journal. In the article, Robertson analyzes the ethical debates around research that uses human embryonic stem cells, or ESCs, and categorizes the different kinds of concerns within those debates. Researchers obtain human ESCs from human embryos. ESCs are pluripotent, which means they have the capability to transform into various cell types, such as skin cells or muscle cells. Robertson explains that ESCs have great medical potential, but since obtaining them requires destroying embryos, some people oppose the use of ESCs in research. After reviewing the main concerns present in debates over ESC research, he concludes that ESC research is still morally permissible. With “Ethics and Policy,” Robertson argued that ESC research should go forward and be federally funded in the US at a time when many politicians, bioethicists, and scientists opposed such research.
