The discovery of induced pluripoten tstem cells raised the possibility that embryonic stem cells research would no longer be necessary, there be circumventing the ethical issues present in embryonic research. To date, this has not been the case: the stem cell field continues to rely both embryonic stem cells and induced pluripotent stem cell research to progress the understanding of plurypotency and its potential applications (Smith and Blackburn, 2012). Further, it has become clear that induced pluripotent cell research is not free of ethical considerations (Hug and Hermeren, 2011). For instance, the potential of these cells to generate sperm and egg cells, or even a whole new individual, raises new ethical questions about the status of the cells themselves and how they may be used.
