As technological research on stem cells intensifies, so does controversy over the moral character of such scientific progress. Over the past millennium and up to today, current stem cell research has become a controversial topic across the world. Stem cells are non-specialized cells with unique regenerative abilities, allowing them to divide into specialized cell types. Understanding why these processes occur is essential to curing the disease. Critics of stem cell research argue that the extraction of embryonic stem cells involves the destruction of an early embryo, which is tantamount to the act of killing a human being. Although stem cell research is a very controversial topic, it is mandatory to pursue stem cell research within ethical boundaries for the sake of humanity. Embryonic stem cell extraction involves the destruction of an early embryo, which means the death of a potential future human being. Is it necessary to kill a future human being to save the current one? The process of extracting embryonic stem cells requires an abortion. Abortion is performed at an early stage, when the cell mass has not developed a system capable of detecting pain or emotion. Embryonic stem cells are found in the inner part of an embryo, called the “inner cell mass.” The inner cell mass is capable of making all types of cells in the body. Initially, cells do not perform a specific function. When stem cells are exposed to an environment of other cells such as skin or neural cells, they “transform” into the surrounding structure. When placed in damaged tissues, embryonic stem cells repair the damaged cells. The ethical dilemma raised by abortion has led scientists to search for an alternative to embryonic stem cells in which the death of humans is not involved.

Current cancer therapies are very painful and involve the destruction of good tissues as well. Stem cells that destroy cancerous tissue can be modified and used to kill all the cancer cells in a body. By injecting stem cells that only destroy cancer cells, no damage is done to the good tissues. Stem cell research needs to be done so that scientists can develop a method that is fully capable of repairing cells. The benefits of stem cell research far outweigh the controversies. In the long term, an increased ability to cure disease would reduce the cost of healthcare globally. In the short term, it will take a lot of money to acquire the knowledge needed to save lives. In the long run, stem cell research is worth the money spent. This is only achievable if stem cells are studied.
