Recommended: Despite the negative controversies, stem cell research can be the key to future success
The medical world is no stranger to controversy surrounding its attempts to create a utopia with no disease or injury that cannot be cured. To summarize it, regenerative medicine is a new practice that allows our body to fix itself using its own cells. This would not only cure, for example, a pair of failing kidneys; it would eliminate the thousands of deaths a year of those on the waiting list for an organ donation. The ability to regenerate dying cells, which make up the tissue forming an organ, is possible with stem cells. A stem cell is a simple cell that has the ability to grow into any specialized cell in the body. There are three different forms of these stem cells found within the human body. Somatic stem cells, also referred to as …show more content…
The ability to create these cells is what makes paralysis in the body a little less life altering. Each year there are approximately twelve thousand five hundred new spinal cord injuries in the United States alone. Roughly thirty-five percent of these injuries leave the person unable to use or feel their limbs and torso. In the book Stem Cells: An Insider’s Guide author Paul Knoepfler says, “The range of severity of effects from SCI varies with the location and intensity of the trauma (the higher in the spinal column generally the more severe the injury), but the injuries frequently are profoundly devastating. Only rarely do patients who appear to have serious SCI (e.g. paraplegia) experience a complete recovery and usually signs of recovery would begin within days or a few weeks” explaining the how although some cases of spinal cord injuries are less severe than others, they are both still life altering. Regaining control of movement and sensation in these affected parts of the body would be nothing short of a medical miracle. Could this miracle be found within one’s own body? With the help of researchers’ new studies and trials, the answer to that question appears to be, yes. The body already uses stem cells to repair everyday mishaps, such as a small paper cut on the finger or a bruised knee. According to the book previously mentioned, researcher Hans Keirstead has possibly come up with a solution to heal the injured spinal cord. Keirstead used embryonic stem cells to create different kinds of spinal cord cells. Though this treatment has great potential, it does not seam possible to treat if an injury is too severe, or it has not been treated close to the time of the
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.
Until recently there was virtually nothing doctors could do for the 500,000 Americans who have strokes each year, the 500,000 to 750,000 who experience severe head injury, or the 10,000 people who are paralyzed after spinal cord damage (3). However, that is about to change. Researchers now think it may be possible to replace destroyed brain cells with new ones to give victims of stroke and brain injury a chance to relearn how to control their body, form new thinking processes, and regain emotions. After demolishing the long-standing myth that brain cells cannot regenerate or proliferate, scientists are developing ways to stimulate cells to do just that. Although stroke, head injury, and paralysis are three of the most devastating things that can happen to anyone, scientists have recently learned that the damage they cause is not preordained. It takes place over minutes, hours, and days, giving them a precious opportunity to develop treatments to halt much of the damage. Most of the new remedies are not yet available, but an explosion of research in the last five to ten years has convinced scientists that some of them will work (8).
Through the continuing studies focused on regeneration and stem cells, scientists can try to see how manipulate totipotent cells found in humans to regenerate into any cell needed throughout the body (Wagner et al., 2012). Humans will benefit from advances in regeneration when faced with degenerative diseases that affect the muscular system or major organs necessary for life. Regeneration can help rebuild organs or muscles damaged by infection or disease and change medicine and human health (Salvetti et al., 2009).
Stem cell research is a heavily debated topic that can stir trouble in even the tightest of Thanksgiving tables. The use cells found in the cells of embryos to replicate dead or dying cells is a truly baffling thought. To many, stem cell research has the potential to be Holy Grail of modern medicine. To many others, it is ultimately an unethical concept regardless of its capabilities. Due to how divided people are on the topic of stem cell research, its legality and acceptance are different everywhere. According to Utilitarianism, stem cell research should be permitted due to the amount of people it can save, however according to the Divine Command of Christianity, the means of collecting said stem cells are immoral and forbidden.
Scientists would be able to grow spinal cells from pluripotent stem cells. These cells could possibly repair spinal cord damage. Those afflicted by paralysis, such as Christopher Reeve, could possibly move again. Stem cells could also be used to grow nerve cells, possibly combating Parkinson’s disease or Alzheimer’s. While it will be many years before scientists may actually be able to find a way to combat these diseases, there is a great promise in stem cells.
Stem cells are undifferentiated cells that can differentiate themselves into specific cell type. There are two types of stem cells. The first one is the adult's stem cell. These stem cells can be found in various places in an adult human body, like the brain, the bone marrow or the liver. The other type of stem cells is the embryonic stem cells. These cells are found in embryos before its implantation in the mother's uterus. At this stage the embryo is divided in two types of cell. The first one is the outer cluster of cell that forms the embryo that will become part of the placenta once the embryo hatch. And the inner cluster is the source of embryonic stem cell since it consists of undifferentiated cell that will divide and differentiate to form all the organs and tissue needed in an adult organism. As stem cell are undifferentiated cell they can become whatever cell type is needed in an organism and could be the solution to diseases that are, at this date, incurable. (Medical News Today, 2013). Most of the ethic's problem of the stem cells researches come from the embryonic stem cell researches and how the cells are collected. Embryonic stem cells can be obtained in several ways. The first one is after a couple's fertility treatment, there might be some embryos left and the couple can decide to donate their embryos to research. The second option is to collect stem cells from a foetus after an abortion. And the last possibility is to use therapeutic cloning. Using an ovum from witch the nucleus was taken off and the nucleus of a somatic cell, the origin of this cell in the body doesn't matter, it can come from the skin for example, it is possible to create an embryo and get the stem cell from the created embryo. But in all of...
...eal or repair themselves, but after a breakthrough in Spinal cord research, done on a rat, it was discovered that the spinal cord “can support the development of transplanted cells”. Several anesthetised rats were given spinal cord injuries and after about two weeks, scientists transplanted human nerve stem cells into their injured spinal cords. Three months after the rats were injected with the human nerve stem cells, the scientists found that some of the stem cells had developed into support cells instead of nerve cells, yet some had developed into mature nerve cells. After about six months, the scientists discovered to their disbelief not only did the human stem cells survive in the rats’ spinal cords, but they underwent mitosis at least twice, and there were three times the amount of human stem cells found in the rats than the amount that was injected initially.
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).
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?
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...
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 initially wanted to focus on the nerves located in the spinal cord so those who are paralyzed are not wheelchair bound for the rest of their lives. I soon realized if nerve pathways in the brain could be restored, then the same process could be applied to nerves in the spine. The reason why prosthetics are able to work is due to the fact that neural pathways in our peripheral nervous system (PNS), nerves that connect our limbs to the CNS, are able to regenerate on their own. These neurons are covered with Schwann cells that facilitate the regeneration of the axon, the part of the cell responsible for transmitting signals. Certain proteins located in the CNS, astrocytes and
Regenerative medicine is a multidisciplinary field concerned with creating living, functional tissues to repair or replace tissue or organ function lost due to age, disease, or congenital defects (US National Institutes of Health). It has been 20 years since the idea of Regenerative Medicine sprung. It all started with the use of tissue engineering to replace body organs or tissues with the ones grown in lab, made using the cells from the targeted organs. Since the discovery of stem cells, most research in the field of regenerative medicine has been focused on the manipulation of stem cells so they can be used to repair or replace any type of body cell or tissue which before the stem cell discovery was not possible. And so with time, the two terms regenerative medicine and stem cells have become quite linked.
There has been a great debate on whether there should be federal funding for stem cell research over the last decade. This has been a very controversial subject because in order to obtain stem cells, scientists must destroy a human embryo; making this a subject ripe with emotional turmoil. For close to three decades, the status on funding for stem cell research has remained in limbo. In 1973, the Supreme Court ruled that abortion is legal in the first two trimesters, a decision made in the famous case of Roe v. Wade. In 1996, the Dickey-Wicker amendment was adopted, stating that there shall not be any federal funds “for the creation of a human embryo for research purposes in which the embryo is destroyed, discarded or knowingly subjected to risks of injury or death” (Annas).
