Stem Cell Ethical Issues

1314 Words6 Pages

In this essay I will be talking about stem cells, how they work, ethical and moral issues that are currently surrounding them and what we can look for in the future. Stem cells are undifferentiated cells in the body which change into specialised cells. During mitosis they can divide and produce more stem cells and are found in multicellular organisms and mammals. The two main types of stem cells are; embryonic stem cells, which are found in the inner cell mass of a blastocyst, whereas adult stem cells are found in varying tissues. In adult organisms, stem cells are a way for the body to repair itself when it gets injured or when it’s needed to replace dead or damaged cells. In developing embryos, stem cells differentiate into all specialised …show more content…

The hope for this is that the transplant of stem cells are introduced into the body and replace damaged or dying cells, taking over their function and repairing any tissue damages. Stem cells can also be used in an opposing way to tissue repair, by removing cancerous cells in the body. This attempt is carried out by using the “homing ability” of stem cells as they automatically know to go to a site of damage. Engineered stem cells deliver compounds which are toxic specifically to those tumours, which goes back to them being used for medicinal purposes. In recent years stem cell therapy has been joined with gene therapy. This is because stem cells can be manipulated outside the body genetically. (Wellcome Trust, Date unknown)
Stem cell transplant is used as a treatment to attempt to cure certain cancers, such as lymphoma, leukaemia and myeloma. During this you have high doses of chemotherapy sessions, occasionally with radiotherapy of the entire body. This type of medicine has a high chance of killing cancerous cells; however it also kills the stem cells found in bone marrow. After receiving chemotherapy and radiotherapy treatments, stem cells from a donor are put through a drip connected to your vein which replaces the stem cells which were killed during treatment. (Cancer Research UK, …show more content…

The study of stem cells still isn’t well known which is why I also agree with using stem cells taken from embryos, as it can massively help with research into the matter and we can have a better understanding of how they work. With this research we can investigate further and see if stem cells can be used in drugs; if so we can then research to see how the body reacts to stem cells being taken in drug form like how penicillin

Embryonic Stem Cells In Mary Shelley's Frankenstein

For example, Alzheimer’s disease is a disease that is caused by brain cell death. Alzheimer’s does not have a cure, and the only treatment for it is medication that will slow the death of cells. However, if embryonic stem cells were used, they could replace and, theoretically, stop the death of brain cells, which would in turn, halt the disease. So overall, this treatment could dramatically benefit patients struggling through diseases like Alzheimer’s, Parkinson’s, cancer, and diabetes. Furthermore, the increase of quality of life for these living people is more than worth the possible destruction of a cluster of

Hans Spemann's Argumentative Essay On Stem Cell

1761 Words | 8 Pages

This transformation to totipotency is intricate, not completely comprehended and the subject of late research. Investigate in 2011 has demonstrated that cells may separate not into a completely totipotent cell, but rather into a "complex cell variety" of totipotency. Immature microorganisms looking like totipotent blastomeres from 2-cell organize fetuses can emerge suddenly in the embryonic foundational microorganism societies and furthermore can be actuated to emerge all the more much of the time in vitro through down-direction of the chromatin gathering action of CAF-1.The human advancement model is one which can be utilized to portray how totipotent cells emerge. Human improvement starts when a sperm treats an egg and the subsequent prepared egg makes a solitary totipotent cell, a zygot. In cell science, pluripotency (from the Latin plurimus, which means a lot of, and potens, which means having power) alludes to a foundational microorganism that can possibly separate into any of the three germ layers: endoderm inside stomach lining, gastrointestinal tract, the lungs, mesoderm muscle, bone, blood, urogenital, or ectoderm epidermal tissues and

Stem Cell Research Persuasive Essay

617 Words | 3 Pages

Stem cell research has become one of the most controversial current topics of biology. This controversy comes from the idea that these stem cells are only embryonic stem cells, and the only way we get them is from the destruction of human embryos. By definition, a stem cells is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. Which simply means they are cells found in the human body that can create any other kind of human cell, so under further observation, stem cells could cure many diseases. Despite prior ideas, there are actually two types of stem cells, embryotic and somatic (adult) stem cells.

The stem cell research is the research, which mainly conducted to use stem cells for medical purposes. Stem cells are the cells that exist in the body or embryo which can become multiple types of the cells via cell differentiation. Although it has much potential to benefit the humanity, it should not be accepted due to ethical issues, financial issues and possible risks. There are two types of the stem cells, which are embryonic and adult stem cells. The embryonic stem cells pose many ethical issues.

One potential application for stem cells is there ability to treat disease and help therapies. Donated organs and tissues are what people to turn to right now to treat their damaged organs. The number of available organs is almost twice the number of available organs. Waiting lists for these organs are huge and most people die awaiting theses transplants. Stem cells on the other hand, offer a replacement to these organs, and most of the time as less deaths.

In today’s time about nearly as 70% of the American population are pro, for having the use of stem cell researched, compared to the 27% who believe it’s morally wrong. A high rise compared to a past poll conducted in 2004 with it being at about 60% who say it’s morally right. When people are asked of or brought to attention by stem cells, some my automatically think of “stem cell research”, and second to that they might as well be thinking “controversy”. Over the past few years the topic of stem cells has really been brought to world as a new study, but has come so far since the first day it was discovered. Stem cells not only has been categorized as a potentially revolutionary treatment, but as well as a sensitive, unethical issue for certain groups of people.

The three major types of therapy are: • Adult stem cell transplants using bone marrow stem cells - This is also called bone marrow transplantation (BMT). This technique is used to restore cells that have before been destroyed by a lot of chemotherapy or radiation therapy. With the help of BMT and PBSCT (pheripheral blood stem cell transplantation) patients can now receive higher doses of chemotherapy and/or radiation therapy for, for example, fighting cancer. • Adult stem cell transplants using peripheral stem cells - PBSCT is the same as BMT, the only difference is that with BMT bone marrow cells are transplanted and with PBSCT peripheral blood stem cells.

Understanding how the adult stem cells are used in treatments and their successes is necessary to learning why adult stem cells are more effective than embryonic stem cells. Adult stem cells are used widely today. Bone marrow transplants are often used to treat Leukemia- a form of cancer that affects white blood cells- or to help replenish the cells of anyone who underwent chemotherapy treatment. Bone marrow transplants have been performed since the late 1960s and have a 100 day survival rate of 98 percent (Volumes and Measures). Adult stem cells can also be used to grow skin grafts for patients with life-threatening burns (What Diseases and Conditions can be Treated With Stem Cells?).

Gene editing is the alteration of a person’s genetic material to delete undesirable traits or to create desirable new ones. Scientists can identify a defective DNA strand to be cut out and changed, then they use a protein that acts like scissors to cut out the improper gene and cells, then a healthy strand of DNA is inserted at the cut site and enzymes repair it (Crow). The goal of gene editing is to treat genetic disorders. Gene editing could potentially decrease or even
