However, there would also need to be an extended period of longitudinal analysis of the effects of the therapy on the experimental group mice's health to see if the improvement continued and did not produce damaging side effects. The MSCs in the liver therapy are not derived from human embryos and thus the objections to discarding human embryos are not a factor in the ethical discussion about the therapy. In

Essay Topic Examples 1. The Ethical Dimensions of Embryonic Stem Cell Research:      This essay would delve into the controversial aspects of embryonic stem cell research, focusing on the debate surrounding the moral status of the embryo. It would explore the ethical implications of using embryonic tissue, the potential consequences for societal values, and the various positions held by religious groups, ethicists, and scientists. 2. A Comparative Analysis of International Stem Cell

Stem cells are a hot topic for the media today because our understanding of them has potential for incredible scientific advances in the field of biotechnology, yet we struggle because there are questions of morality raised by the methods by which they might be used. While in centuries past, it was commonly accepted within the scientific community to vivisect the mentally insane or criminally convicted for the purpose of scientific

The exchange of the defective gene could be brought about by a process called homologous recombination. One of the first gene therapy experiments, though well intentioned, caused the death of the patient. Researchers at the University of Pennsylvania introduced a normal gene into a boy's body by using the rhino virus as a carrier. The body's immune system attacked this as a pathogen. This led to eventual organ failure

Unfortunately, these undifferentiated cells cannot be harvested or removed from an adult because an adult's cells have already matured. Once matured, cells can't be overwritten to become another type of cell. but, embryonic cells are technically at a stage of growth where they are clearly cells but they have not yet reached a stage of becoming a specialized cell. Therefore, the stem cells can still be rewritten or redirected so

Scientists have been aware of the existence of these stem cells for many years but have only recently realized the potential medical applications of the cells. More than a decade ago, scientists discovered that if the normal connections between the early cellular progeny of the fertilized egg were disrupted, the cells would fall apart into a single cell progeny that could be maintained in a culture. These dissociated cells, otherwise
