Patients could be exploited by paying for expensive treatments and being given false hope of a cure as stem cell therapies are only in their developmental stages.Much of the research is being carried out by commercial clinics, so reported successes are not subject to peer review.Whether the benefits of stem cell research use outweigh the objections.Educating the public about what stem cells can, and can't do, is important.At what stage of its development should an embryo be regarded as, and treated as, a person?.Embryos could come to be viewed as a commodity, and not as an embryo that could develop into a person.For therapeutic cloning, is it right to create embryos for therapy, and destroy them in the process?.A source of embryonic stem cell is unused embryos produced by in vitro fertilisation.Cultured stem cells could be contaminated with viruses which would be transferred to a patient.Mutations have been observed in stem cells cultured for a number of generations, and some mutated stem cells have been observed to behave like cancer cells.The difficulty in obtaining and storing a patient's embryonic stem cells.The difficulty in finding suitable stem cell donors. Pluripotent stem cells derived from the inner cell mass of the blastocyst.There is no guarantee of how successful these therapies will be, for example in the use of stem cells in healing damage caused by Parkinson's disease.Some variables which would be considered when discussing stem cells include: Clinical issues Embryonic stem cells have a high chance of immune rejection and also have ethical dilemmas and iPSCs have genetic instability. Sometimes, there are no right or wrong answers. It is important to obtain a balanced view. For therapeutic cloning, is it right to create embryos. Some advantages and disadvantages of using large animal models in a study. They will also depend on whether the stem cells are to be used for therapy or research. Ethical issues A source of embryonic stem cell is unused embryos produced by in vitro fertilisation. cells including embryonic as well as adult stem cells or maybe somatic cells. These issues will be different for growth and transplant of adult stem cells, embryonic stem cells and therapeutically-cloned stem cells. Rare species at risk of extinction as a result of. Plant clones can be produced in weeks at a relatively low cost for their potential value. They can then be used to produce clones of plants quickly and economically. There are clinical, ethical and social issues with their use. Unlike in animals, plant stem cells can be obtained easily, and without ethical objection, from meristems. treating patients with currently untreatable conditions.Many people view this as having a negative and possibly detrimental effect on our society (we will discuss more about the process and the advantages and disadvantages of cloning towards the end of this course).Benefits and risks associated with the use of stem cells in medicine Pluripotent mouse embryonic stem cells (ESCs) were established in the early 1980s 45,46.Leukaemia inhibitory. Whilst researching stem cells, we are also researching human cloning. The difference between mice and humans is evident in the culturing of their stem cells. This research can also have a huge benefit on correcting birth defects in unborn children due to the effects of stem cells on embryos. However, these cultured cells begin to change over time, so scientists must create new lines in order to have an ongoing source of cells to study. Moral argument – the main moral argument to stem cell research is that altering the structure of genes is interfering with the natural functions of the human body, possibly creating greater risks in the development of new diseases. An embryonic stem cell line is a population of cells that can grow and divide indefinitely outside the body, providing a source of cells for scientists conducting stem cell research. Further advancements into research also need to be made before stem cell treatment can be used safely.īy researching stem cells, we have gained a better knowledge into human growth and how the human body works, which is vital in the advancement of medicine. Unknown side effects – because research into stem cells is fairly new, the side effects of their use remains unknown. These issues will be different for growth and transplant of adult stem cells, embryonic stem cells and. Medical benefits – stem cell research offers benefits in regenerative medicine and also with therapeutic cloning in order to treat some chronic illnesses. medical research There are clinical, ethical and social issues with their use. The table below has been provided to help highlight these: Advantages There are a number of advantages and disadvantages to using stem cells in medicine.
