The mention of stem cell therapy is definite to draw perplexed reactions from those who know nothing about the subject. Maximum of us have been informed that stem cells are gathered from a human embryo which is devastated in the process. But, the fact is that these therapies as practiced with categorical success are based on the use of mesenchymal stem cells gathered from the patient's own bone marrow and blood. There is a brilliant reason for this, fat removed from the ethical constraints revolving around fetal cells. For the most applied of contemplations, fetal stem cells are very poor weaponries against any complaint in that they are brilliant producers of their own ailment i.e. cancer. Fetal cells divide so speedily, that the risk of cancer …show more content…
All human life starts with an ovum and a sperm. Cells then ascend in the fertilized ovum, which after a few days in the womb grow into embryonic stem cells. These cells are much unspecialized and have the ability to develop into all of the 220 human cell categories. An entire human being cannot develop from these cells as they are. They need to continue their development in the womb until they change into mature, distinguished cells which then take over a specific function of the body. Throughout our lives however, we have cells that remain much unspecialized. The regeneration of our skin, for instance, is a continuing process and continues until we expire. Wounds heal. Hair grows. We live with cells which are very unspecialized, can remain to divide as we go through life and help our body to renew and repair itself. These are the cells used in stem cell therapy in India. Adult cells have been and continue to be found in just about every body tissue; the hair, the brain, the liver, the blood, the bone marrow, etc. If body tissue is impaired, these stem cells flock to the smashed region to repair it. This offers the body with its own repair system, and modern therapy is destined to exploit this
Are stem cells ethical to use in medical research? The most basic cells in the human body are stem cells. Because doctors use stem cells for medical treatment of chronic ailments, stem cells play an important role in human medical research. However, despite the benefits of stem cells in medical treatment, controversy surrounds the methods employed to obtain them. Should researchers continue to use stem cells?
Stem cell research began in 1956 when Dr. E Donnall Thomas performed the first bone marrow transplant (“Adult stem cells are not more promising,” 2007). Since that time, research has evolved into obtaining cells from a variety of tissues. According to stem cell research professors, Ariff Bongso and Eng Hin Lee (2005), “Stem cells are unspecialized cells in the human body that are capable of becoming cells, each with new specialized functions” (p. 2). Stem cells are in various adult tissues, such as bone marrow, the liver, the epidermis layer of skin, the central nervous system, and eyes. They are also in other sources, such as fetuses, umbilical cords, placentas, embryos, and induced pluripotent stem cells (iPSCs), which are cells from adult tissues that have been reprogrammed to pluripotency. Most stem cells offer multipotent cells, which are sparse...
As technology stem cell research intensifies, so does the controversy about whether such scientific progress is moral. In the past millennium to today the present stem cell research has become a controversial topic across the world. Stem cells are unspecialized cells that have unique regenerative abilities, allowing them to divide into specialized cell types. Understanding why these processes occur is essential to curing disease. Critics of stem cell research argue that the extraction of embryonic stem cells involves destroying an early embryo, equating the act of killing a human. Although stem cell research is a highly controversial topic, it is compulsory to continue stem cell research within ethical boundaries for the benefit of mankind.
Stem cells help us to maintain and heal our bodies, as they are undifferentiated cells, their roles are not yet determined. They have the ability to become anything during early life and growth. Stem cells come from two sources, namely: embryonic stem cells (embryo’s formed during the blastocyst phase of embryological development) and adult stem cells (see figure 3).
The ethical issues behind the method in which stem cells are obtained out weigh the benefits of stem cell therapy. We should not try to play God, in the aspect of creation of living beings just to be sacrificed for the “betterment of mankind”. Many egregious acts have been committed under the guise of “the greater good”. This is one instance in which the ends do not justify the means.
Stem Cells are cells that scientist have began to try and use to help people. “In the mid 1800s it was discovered that cells were basically the building blocks of life and that some cells had the ability to produce other cells.” With the discovery of stem cells came the opening to a new area of development in what could be done with health and medicine of the world. Of course throughout history, stem cells have been a very heated subject between different groups of people who believe it is right or wrong. Some people believe that this form of research is against ethical or moral values. They too see this as being wrong because they view human embryos as a form of life. These cells are neutral cells that can be turned into any other one that is needed at the time. Stem cells can make more of themselves when they aren’t being used allowing them to be ready when something happens. In the human body, stem cells help repair the tissue that has been broken, torn, or lost. They help fix bones, heal abrasions, and even repair internal organs if needed. Scientist have the ability now to mani...
Have you ever seen a movie or read a book where they can tell what your child will look like or if they have a disease or birth defect. Or have you ever wondered how the world would be shaped if we could have clones or even erase genetic diseases. All of these things are theoretically possible with stem cell research. If we are able to reach this point what would we have to sacrifice in the process. To understand humanity would we have to sacrifice the values that truly make us human? What would the fail rate be if we are able to genetically enhance the human body?
Embryonic stem cell research is the medical study of cells taken from embryos before they are able to implant into a uterus. This procedure – harvesting the cells – ultimately destroys the embryo rendering it non-viable and unable to sustain life. Adult stem cell research is simply the study of stem cells harvested from adults and used in many areas of medicine. Numerous groups are opposed this sort of research because they feel it infringes on the right to life, while others do not believe that an embryo that has spent five days in a petri dish should be considered a human. In the 1800’s the first discovery of stem cells occurred. This discovery proved that some cells could spawn other cells. However, it was not until the early 1900’s that research demonstrated stem cells could generate blood cells. This was very promising in the medical community at that time since so many diseases ran rampant and were incurable. During the infancy of stem cell research, both animal and human stem cells were used. Now, for medic...
This paper focuses on the benefits of stem cell research in the medical and nursing field. New technology is always being created to help us understand the way the human body works, as well as ways to help us improve diseased states in the body. Our bodies have the ability to proliferate or regrow cells when damage is done to the cells. Take for example the skin, when an abrasion or puncture to the skin causes loss of our skin cells, the body has its own way of causing those cells to regrow. The liver, bone marrow, heart, brain, and muscle all have cells that are capable of differentiating into cells of that same type. These are called stem cells, and are a new medical tool that is helping regrow vital organs in our body to help us survive. Stem cells can come from adult cells, or the blastocyst of the embryo. The cells that come from these are undifferentiated, and can be specialized into certain cell types, making them available for many damaged tissues in the body. While using stem cells in the body is a main use, they are also being used to help doctors understand how disease processes start. By culturing these cells in the lab and watching them develop into muscles, nerve cells, or other tissues, researchers are able to see how diseases affect these cells and possibly discover ways to correct these diseases. While researchers have come very far in using stem cells, there are still many controversies to overcome when using these cells.
I am very interested in the topic of Organ transplantation. I am interested in biology and the process of surgeries. What intrigues me is the process of saving someone’s life in such a dramatic and complicated process. My dad happens to be a doctor and in his training he cut open a human body to see for himself the autonomy of the body. So being interested in the field of medicine is in my blood. Modern technology helps many people and saves people around the globe. However even with modern technologies that progress mankind, bio medical and ethical dilemmas emerge. And ultimately life falls into the hands of the rabbis, lawmakers and philosophical thinkers.
From the discussion above it is very clear that there are different opinions on the pros and cons of stem cell research. Based on the recent researches, scientists have the capability to work out the alternatives for embryonic stem cell research. And the usefulness compare to embryonic stem cell remains unknown. Undeniably, the stem cell research issue has its most complex parts to be resolved and surmounted. But perhaps we can disclose the way to carry out stem cell research with the balance of bioethics and most importantly, do no harm for humankind one day.
One of the most controversial topics in the media today is the question of the morality of research on human embryonic stem cells. According to a Gallup poll taken in May of 2010, 59% of Americans believed medical research using stem cells obtained from humans was morally acceptable, where 32% believed it was morally wrong. (Saad) This will always be a difficult issue for me to take sides on. There are so many arguments for and against and so many ethical theories that support and oppose it. I am going to try to touch on a few of these theories and how they apply to the research done on human embryonic stem cells.
Organ transplant procedures started in the early 1950s. If the transplants are successful it can extend life and improve the quality of life in recipients. This makes the procedure of organ transplants a topic of great importance. There are thousands of people who require organ donations to live and not enough donors to match the need. There is a structured way to determine who is in a greater need. It is organized by a national transplant list. Different factors determine who is at the top of the list. The thought of celebrities, famous people and rich people taking precedence on the list is not even feasible because of the way the system is set up. Every day people are dying while waiting to receive a donation. These are completely unnecessary
Could you imagine being able to create new organs, tissues, muscles, and even food? With embryonic stem cell technology, believe it or not, these things are possible. Stem cells are the body's raw materials. Specifically, they are cells from which all other cells with specialized functions are generated. Under the right conditions in the body or in a laboratory, stem cells can divide to form more cells called daughter cells. These daughter cells either become new stem cells or turn into specialized cells with a more specific function, such as blood cells, brain cells, muscle cells or bone cells. The possibilities are almost endless. The debate and main issue with this technology is that the actual stem cells come from embryos. Embryos are an unborn or unhatched offspring in the process of development. Although there is controversy surrounding these cells, embryonic stem cells should continue to be researched and used, because they have so much potential.
Stem cells offer exciting promise for future therapies, but significant technical hurdles remain that will only be overcome through years of intensive research. Stem Cells have the incredible potential to develop into many different cell types in the body during early life and growth. Scientists primarily work with two kinds of stem cells from animals and humans. The embryonic stem cells and the non-embryonic stem cells. Stem cells are the cells from which all other cells originate. In a human embryo, a large portion of the embryo’s cells are stem cells. These stem cells can be used for cell-based therapies. Cell-Based therapies are treatments in which stem cells are induced to differentiate into the specific cell type required to repair damaged or destroyed cells or tissues. Stem cells are versatile and offer the possibility to treat a number of diseases including Alzheimer’s, stroke, cardiovascular disease, diabetes, etc. The problem is that for the process of embryonic stem cell research and embryo will be destroyed if used. This raises a moral issue and questions of whether stem cell research is unethical or not.
