Recommended: Arguments in favor of stem cells
Scientists believe that stem cell has an incredible potential to develop into many different cell types in the body throughout early life and growth. With all the controversy surrounding studies of stem cells, people miss the importance and benefits of stem cell use and how beneficial it is in the medical field. Stem cells have many applications for treating diseases and the potential to treat even more diseases in the future which scientist are working on. There are many benefits of using stem cell, there is a few studies that show to have been successful and has helped. With stem cells, you have the potential to reverse diseases, like heart attacks, Parkinson’s disease, and genetic defects. Stem cells can be used for laboratory growth of …show more content…
Normally there are very small amounts of stem cells in tissues, and once they are removed from the body, their size to divide are limited, which are making the generation of large amounts of stem cells difficult. In laboratories, many scientists are finding better ways to grow large quantities of adult stem cells in cell culture and to control or manipulate the stem cells to make specific cell types so they can be used to treat diseases, and injuries. Some potential treatments include repairing heart muscles, diabetes, cancer, aids, and more. Some test that is used to identify adult stem cells is by leveling the cells in a living tissue with molecular markers and then they define the specialized cell type that was produced. Another way is they remove cells from a living organism, like an animal and label it in the cell culture. Then they transplant them back into another live animal to see if the cells replace their tissue of the origin. This procedure must establish that a single adult stem cell can produce a line of genetically identical cells that then gives intensification to all the appropriate distinguished cell types of the
Stem cells are the building blocks of the human body. Embryos consist of unspecialized stem cells that transform into the various specialized cells in the body such as cardiac, muscle or bone cells. Fetuses also have stem cells. However, the stem cells are divided into types like muscle, bone or nerves and don't perform a specialized function. Surprisingly, adult bodies also contain stem cells. In adults, stem cells are undifferentiated but limited to specific tissue type. When needed, the stem cells transform into the cells needed for repair and maintenance. The most common source of adult stem cells is bone marrow. Researchers also acquire stem cells from umbilical cords. Without stem cells, embryos could not develop into fetuses and adult
Opposing Viewpoints offers unbiased opinions on the future of embryonic research as well as how they have currently been used to cure many diseases. In addition, the article specifies how developing ethical standards to ensure that the use of embryos remains moral, allows for science to remain ethical. Many of the topics mentioned in this viewpoint consider bioethics and remain consistent throughout. Essentially, the purpose of this article was to establish a middle ground between ethics and science.
Stem cells are valuable due to the fact that they are ? non-designated,? (have no specifically assigned task in the body, i.e. liver cells, brain cells, skin cells, etc.) and they also have the ability to divide indefinitely. Thus, theoretically stem cells could replace any damaged or lost specifically designated cells within the body.
Because stem cells are essentially a blank slate, scientists are theoretically capable of growing any human tissue cell. There is enormous medical potential in this. Stem cell research is the next step in advancing the medical field. It is comparable to the discovery of penicillin or the inoculation for smallpox.
Bonnie Steinbock, in her paper entitled, “What Does “Respect for Embryos” mean in the Context of Stem Cell Research?” argues that using human embryos for embryonic stem cell research is immoral and illicit. She forms her argument on the “consideration of the human subject from the moment of conception” (Bioethics 592). The author supports her argument with five reasons as to why using human embryos for ES research. She explains that the moment the gametes unite, an embryo with human rights is formed. Building off of her first statement, the author explains that it is immoral and illicit to intervene in the development of an individual with rights in a non-favorable way, because
Special cells that are taken from human embryos, called embryonic stem cells (ES cells), actually possess the power to save your life. These cells can serve many medical purposes and have the ability to benefit people in infinite ways.
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...
Stem cells come from adult stem cells, and embryonic cells. Embryonic (blastocyst) stem cells come from embryos that are usually three to five days old. They contain 150 cells that are useable for stem cell research. These embryos are usually created as in vitro fertilization (a bunch of eggs that are fertilized but only one is put inside of a woman). Reproduction happens when a male’s sperm is fertilized in a woman’s egg to create a zygote (cell). Scientists can verify the cells are embryonic by them being able to be duplicated and the cells ability to become other cell types; this makes embryonic cells flexible. Adult stem cells are found in adult tissues in very small numbers. These cells are only used in certain areas where they are found such as bone marrow or adipose tissue (fat).
Long after Shelley wrote her classic masterpiece Frankenstein and Huxley wrote Brave New World, the ethical controversy of cloning conflicts with modern artificial intelligence research. The question that challenges the idea of negative or positive behavior in a replicated machine relies on its similarity to the source of the clone, whether it emulates human behavior or acts as a “superintelligence” with supernatural characteristics void of human error. Humanity will not know the absolute answers concerning behavioral outcome without creating a physical being, an idea portrayed in Shelley’s Frankenstein in which the creation of a monster emulates from his creator’s attempts to generate life. At the time of the novel’s publication, the idea of replicating a soul portrayed a nightmarish theme with little consideration for the potential scientific advancements to facilitate in reality. It lead the genetic idea of manmade intelligence and its ethics emerging from the relativity of space, time, and original life on the planet. The debate of the existing possibility of sentient machines continues to progress, but the consideration of ethical questions such as “Should we create these artificial people?” and “How does this enactment define the soul and mind?” warranted from primitive questions about machine learning within the last century. After the initial proof of possibility for sentient machines, the perfection of cloning will generate “good” behavior at its perfect state several generations from now. The perfect machine portrays the potential for sensible human behaviors including compassion, mentality, empathy, alertness, and love. Humanity of the twenty-first century possesses the knowledge to fantasize the idea of artificial ...
Every year countless people are diagnosed with cell based diseases, 7.6 million a year alone receive the petrifying news that they have cancer. But what if we could eliminate the idea that a cancerous diagnosis is the equivalent of a death sentence? The use of embryonic stem cells could, for the first time, make diseases like cancer or parkinson a non-issue. This is why the use of embryonic stem cells should not be viewed as unethical but rather a huge step towards unthinkable medical breakthroughs and the eradication of life threatening diseases.
As stated on the Neostem website, “Stem cells have remarkable potential to develop into many different cell types in the body during early life and growth.” They are used for cell therapeutics and the advantages are many. They offer a source of renewable cells to replace the damaged or dead cells that can be cause disabilitating ...
Over the past years, stem cell research has been very famous through the scientific community and the media. Stem cells are pluripotent cells that are present in every single organism on Earth. The power of stem cells are beyond imagination. Stem cells have the power to turn into any type of cells. Some examples are, blood cells, nerves, cardiac muscles, and the list goes on and on. The scientific community has recently taken a large interest in stem cells. They have used stem cells to treat horrible misfortunes that people have been diagnosed with. Some examples of the diseases that are being treated by the use of stem cells are, Alzheimer’s, Parkinson’s, spinal cord issues, strokes, diabetes, damaged organs, and even cancer! However, despite the infinite potential for medical treatments, the topic of stem cells is surrounded by enormous amounts of controversy. The questions that feed the controversy are about how the stem cells are acquired and about how the gained knowledge would be used. However, it is necessary for mankind to keep stem cell research alive in order to save lives while taking care of any unethical topics about it.
In the Bioethics book, the Magisterium of the Church argues against the use of embryonic stem cells and refers to it as “the first ethical problem”. The main argument supporting the claim that its unethical to destroy human embryos goes as follows: (1) It is morally impermissible to intentionally kill innocent human beings; (2) the human embryo is an innocent human being; (3) therefore, it is morally impermissible to intentionally kill the human embryo. While this is a valid argument that follows the form modus ponens, it is not sound, thus I argue that the use of embryonic stem cells is permissible.
The Benefits of Human Cloning In recent years, many new breakthroughs in the areas of science and technology have been discovered. A lot of these discoveries have been beneficial to the scientific community and to the people of the world. One of the newest breakthroughs is the ability to clone. Ever since Ian Wilmut and his co-workers completed the successful cloning of an adult sheep named Dolly, there has been an ongoing debate on whether it is right or wrong to continue the research of cloning (Burley).
