Stem cells have the latent ability to cure any disease. Commonly, a disease, known as macular degeneration, develops in the eyes of the elderly. Macular degeneration takes place when damage to the inner retina, known as the macula, occurs. Mark Humayun, Professor of ophthalmology and biomedical engineering at the University of California, theorizes that using stem cells to regenerate portions of the retinal pigment epithelial cells to treat macular degeneration (Can Stem Cells Research Lead to Macular Degeneration Treatment?). "Stem cell therapies are not new. But when scientists learned how to remove stem cells from human embryos, both excitement and controversy ensued" (The Stem Cell Debate: Is It Over?). Excitement over the array of new possibilities, and controversy over the moral and ethic implications, of stem cell research. Quite possibly, stem cells could bring human life invulnerability. Thus, the requisition of stem cell research is imperative to elongating the existence of human life. Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. In addition, in many tissues, they serve as an internal repair system. When a stem cell divides, each new cell has the capability of either remaining a stem cell, or becoming another type of cell with a more specialized function, such as muscle cells, blood cells, or brain cells (Stem Cell Basics). "Stem cells have an interesting history that has been somewhat tainted with debate and controversy" (Murnaghan). In 1998, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos and developed the first embryonic stem cell lines. During that same year, Japanese and American research teams anno... ... middle of paper ... ..." (What are Stem Cells?). Often, "human cells are inserted into animals(like mice or rats) and are allowed to develop. This creates the opportunity for researchers to see what happens when stem cells are implanted. Many people, however, object to the creation of an organism that is 'part human'" (What are Stem Cells?). Stem cells are a class of undifferentiated cells that are able to differentiate into specialized cell types. Common sources of stem cells are embryonic stem cells and adult stem cells. Uncommon sources of stem cells are fetal stem cells and induced stem cells. If research goes accordingly, cures for all major diseases and minor diseases alike, will be attainable. Holding the key to unlocking genetic invulnerability, even at the risk of stirring controversy, the requisition of stem cell research is imperative to elongating the existence of human life.
What are Stem Cells and what do they do? Stem cells are cells made of the bodies “raw materials” and are the only type of cells in the body that have “a natural ability to generate new cell types.”(“Stem Cell Transplant”) Stem Cells have the potential to treat or cure a wide range of diseases and disorders, such as: Parkinson’s disease, Alzheimer’s disease, etc., that affect billions of people worldwide. With a subject such as embryonic stem cell research, whether or not the costs outweigh the benefits is subjective and the cost of life is impossible to measure.
This report does a fairly comprehensive job on educating the public to the definition of stem cells, describing them as “a diverse group of remarkable multipotent cells that are relatively undifferentiated and unspecialized cells of the body.” Stem cells have the capacity for unlimited self-renewal and the possibility to produce differentiated descendant cell types. The main in...
Stem cells are mother cells that have potential to develop into a new different cell in the body. It can self-renew or multiply while developing into other types of cells, for example they can become cells of the blood, heart, bones, skin, muscles and brain. Stem cells were discovered in human cord blood in 1978, and in 1998, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos (early stage of an animal or person before it is born) and developed t...
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 can help cure diseases, repair damaged organs, and replace the need for organ donors. Stem cells may play a major role in cancer research, treatment, and maybe even a cure. Using stem cells in better treatments for diseases can give economic gains for society. According to the Mayo Clinic, over 100 million suffer from diseases that eventually may be treated more effectively or even cured with embryonic stem cell research (“Stem Cell Transplant”). This may be the greatest opportunity to alleviate the suffering of humans. Stem cell research has a lot of potential; there is a long list of diseases and other conditions that stem cells may be able to treat and possibly one day
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.
The issue of stem cell research first began on the scientific scene in November of 1998 when researchers first reported the isolation of human embryonic stem cells. The discovery, made by Dr. James A. Thomson, a biologist at the University of Wisconsin, Madison, offered great promise for new ways of treating diseases through stem cell use. The stem cells, which are derived from several-day-old embryos, can theoretically differentiate into virtually any type of human cell, ranging from blood cells to skin cells (American Association for the Advancement of Science, 2011). According to the American Medical Association (2013), a stem cell is an immature cell that has the potential to become specialized into different types of cells throughout the body. There are two basic types of stem cells: adult stems cells and embryonic stem cells. Embryonic stem cells are produced when a newly fertilized egg begins...
Stem cells are amazing cells that all humans possess throughout their bodies. In today’s world of science, stem cells have become important factors in scientific research. Research with stem cells has been increasing exponentially over the last decade. Around the world, stem cells have been studied to help treat various health problems. The extent to what stem cell research can do is very wide reaching. The existence of stem cells was theorized by Alexander Maximow in the late 1800s. He believed that cells originated from a one type of cell. He was not far off with this theory.
Stem cell research is a big debate in today's society. The argument of whether or not it is morally acceptable has been sparked, as well as court cases and religious and political disputes have begun. Stem cells “can only be obtained by destroying human embryos, nearly every Western legislature had noisy and bitter debates.” (“Is the Great Stem Cell
Stem cell research is a topic that is discussed widely throughout our nation and can have many positive and negative outcomes. There are two different types of stem cells, embryonic stem cells and adult stem cells. Embryonic stem cells are able to differentiate and turn into other cells which are taken from an embryo at a few days old. An adult stem cell is a stem cell that resides in an individual, which can be used for repairing the tissue in which they reside. However, it has been proposed that embryonic stem cells and adult stem cells can either change or may be responsible for abnormal growth which could progress into cancer.
Cells, and especially stem cells, are a very fascinating thing that should be of interest to everyone on the planet. In a human there are over 200 different types of cells, and in total
A stem cell is a cell that does not have a specific job, function or structure and are known as undifferentiated cells which have the potential of becoming many different cell types within the human body. Embryonic stem cells are taken from embryos and are known as pluripotent because they can become all cell types of the body. After development, adult stem cells are found to multiply by cell division to replace dying cells and restore damaged tissues. They are known to be limited to differentiating into different cell types of their own original tissue origin. Embryonic stem cells are taken from three main sources in a human including from cell lines that already exist, spare embryos left over from fertility treatment and from custom made embryos. Adult stem cells can be found in organs and tissues like brain tissue, bone marrow, blood vessels, gut, liver and more. Scientists are now trying to discover how some tissues and organs contain a small number of adult stem cells and how these stem cells help to maintain the tissues and organs.
Scientist believe stem cells may have the potential to help us understand, and possibly cure some of the most threatening diseases and conditions which effect many people today. Many scientists, doctors, families and loved-ones and patients have hoped for this change, however stem cell research has brought up various controversies around the globe.
Stem cells research can help the human with cancer, birth defects and help to build normal cells it is only normal that we should research stem cells. Stem cells are special cells that are undifferentiated and have the capability to become many other types of cells. All stem cells have the ability to renew, replicate, and divide; thus, producing new cells. These cells are separated into categories according to their potential to become other types of cells. Two main stem cell types are embryonic stem cells and adult stem cells. Embryonic stem cells come from four to five day old embryos. They can be found on the inside of the placenta. These stem cells are considered pluripotent, meaning that they can become almost all possible types of
Stem cells are a key component of regenerative medicine. They are undeveloped cells capable of proliferation, self renewal, conversion to differentiated cells, and regenerating tissues. [1] In a developing
