4.How can stem cells be used therapeutically? Some cell-based stem cell therapies are being used to treat burn victims by introducing new tissue or promoting new tissue growth. Another therapy, is by reintroducing good healthy blood to victims of leukemia and other various blood disorders (EuroStemCell, 2018). Pluripotent stem cells are even being used to discover new drugs in cancer patients, so physicians know what type of anti-tumor drugs to use (NIH, 2018). Adult stem cells are able to be isolated through a process called plasmapheresis. When this is done, stem cells can be used to treat hematological deficiencies and to ease the symptoms of cancer chemotherapy. Autologous stem cells are even used in clinical trails with patients who have had a heart attack to repair the heart tissue (Lo & Parham, 2009). Lastly, hematopoietic stem cells that are from cord blood are stored and utilized for allogenic and autologous stem cell transplantation to treat blood disorders in children instead of a bone marrow transplant (Lo & Parham, 2009). The study of stem cells is still new, but the studies being conducted, may hold the answer in curing many diseases that are fatal. People even donate their tissues and organs for stem cell research and to victims that need them when they pass on. Researchers hope that they can perfect the process of stem cells separating into specific cell types, so new cells and tissues can be created. If so, heart disease, macular degeneration, juvenile diabetes, stroke, and possibly Parkinson’s disease can be a thing of the past (EuroStemCell, 2018). 5.What are two major concerns for using stem cells reproductively? 1. Some believe that reproductive cloning from an embryonic stem cell research is unethical. This is because the nucleus is obtained from the developing embryo and placed inside another egg in order to create another person. However, many believe that this process is useless, and it serves no purpose (Gamble, Z., 2017). 2. Some also believe that human life starts when an egg is fertilized, and by retrieving the stem cells in it which kills the embryo, is called murder (Gamble, Z., 2017).
6. Conduct a quick Internet search and briefly explain the current status of laws regarding the use of IVF embryos in stem cell research. In 1973 the Department of Health and Human Services, banned all research that was federally funded that utilized human embryonic stem cells or (heSC). In 1974, Congress decided to do this as well, but they strongly emphasized the banning of embryos that were obtained through IVF. However, in 1992, President George H.W. Bush, made legislation remove the ban, but in 2001, President George W. Bush, mandated an executive order to stop all federal funding for stem cells that were made after 1992.
