Use of Embryonic Stem Cells: In order to extract embryonic stem cells, the embryo has to be destroyed. This is a problem for many people, particularly Christians, as it goes against their beliefs. According to Christian beliefs, an embryo is a life, and killing it is just like murdering someone. As a result, countries such as Germany have banned embryonic stem cell research. However, there are many counterpoints, such as the possibilities of using embryonic stem cell research to come up with new cures for diseases. 

Ownership of Cells: For many years, human donors have been an important part of science, donating cells, tissues, and organs to help research and further our understanding of the human body. However, one question that has arisen from this is the issue of consent, particularly when using the cells. One famous example is Henrietta Lacks (pictured on the right), who had her stem cells taken without permission and used to the advantage of scientists everywhere. Her family hasn't gotten any money, and are suffering from bad health care. This raises the question: Should we inform the patients or not? On one hand, it respects the privacy of the donor. On the other hand, what if they say no, and their cells had a special substance that could cure cancer?

Who Gets the Organs First? As of right now, growing organs are incredibly hard in regenerative medicine. However, the field is rapidly advancing, and scientists will find themselves addressing this issue sooner than later. Some people say that older people should get first-priority, while others say that young people should be the first on the list since they have a full life ahead of them. But it gets even more complicated than that. Life choices also matter. Should an alcoholic be pushed aside for a sober person, since the alcoholic is destroying their organs by drinking? Some doctors say that people shouldn't be judged on their vices and virtues, while others say that the alcoholic should at least try to stop drinking so they don't ruin the organs.
