As technological stem cell research intensifies, so does controversy over the morality of such scientific progress. In the past millennium until today, current stem cell research has become a controversial topic around the world. Stem cells are unspecialized cells with unique regenerative capabilities, allowing them to divide into specialized cell types. Understanding why these processes occur is essential to treating diseases. Critics of stem cell research argue that the extraction of embryonic stem cells involves the destruction of an early embryo, equating to the act of killing a human being. Although stem cell research is a very controversial topic, it is mandatory to continue it within ethical limits for the benefit of humanity. Embryonic stem cell extraction involves the destruction of an early embryo, which means the killing of a potential future human being. Is killing a future human being necessary to save the currently living one? The process of extracting embryonic stem cells requires abortion. Abortion is performed at an early stage where the cell mass has not developed a system that can detect pain or emotion. Embryonic stem cells are found in the inner part of the embryo, known as the “inner cell mass”. The internal cell mass is capable of producing every type of cell 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 inserted into damaged tissue, embryonic stem cells repair the damaged cells. The ethical dilemma raised by abortion has led scientists to look for an alternative to embryonic stem cells that does not involve killing humans. Induced... center of paper... cells are not only a replacement part for treating diseases, but they help us better understand the human body. Current cancer treatments are very painful and involve the destruction of good things. fabrics too. Stem cells that destroy cancerous tissue can be engineered and used to kill all cancer cells in a body. By injecting stem cells that only destroy tumor cells, no damage is done to healthy tissue. 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, a greater ability to treat diseases would reduce the cost of healthcare globally. In the short term, a lot of money is needed to obtain the knowledge needed to save lives. In the long term, stem cell research is worth the money. This is only achievable if stem cells are used
