Recommended: advantages and disadvantages of stem cell research
Stem cells offer great promise for success in future medical treatments. However, there still remains to be biased opinions on whether or not the use of stem cell for research is the most appropriate and effective tool for medical research. This topic is especially important for people who are suffering from disease that is capable of being treated through stem cell use. For these people, the treatment has the potential to change their outlook on life to a positive one. The advancements are diverse and have the potential to help cure numerous diseases and illnesses. Scientists are striving to find even more ways than they have already to repair damaged tissue in the human body and cure these diseases entirely through the usage of stem cells, and scientists believe that this will lead to further medical advancements for researchers. 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... ... middle of paper ... ...he advancement of science (Aug. 12, 2011). AAAS Policy Brief: Stem Cell Research.

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...
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 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
Stem cells are an ongoing research project in which new discoveries are being made about them, and researchers are learning how to use them in new ways. The three current kinds of stem cells all prove to have their own challenges when it comes to using them. The important thing is finding out which stem cell is right for the patient and how much of an ethical concern there is when it comes to using the stem cell. As we learn the best way to use them and they become more popular in the medical field, stem cells will become a new weapon in the fight against certain diseases.
When one thinks of fatal diseases, what comes to mind? Cancer? Organ failure? Brain damage? All of those things and more could be a thing of the past with the incredible potential of stem cell research. Stem cells are like blank cells that can take the form of other kinds of cells. This gives them the ability to heal damaged areas, or grow replacement tissue for tissue that has been diseased. Stem cells can come from several different places, some of which cause lots of controversy and ethical debate. Because of this, stem cell research is not federally funded by the United States government. But, stem cell research has tons of potential and should get more attention for the greater good of our future.
Named the Breakthrough of the year for 1999, human embryonic stem cell research may indeed have the potential to benefit many people who suffer from serious debilitating conditions. Because embryonic stem cells can develop into many different types...
Research on stem cells is advancing knowledge about how an organism develops from a single cell and how healthy cells replace damaged cells in adult organisms. This promising area of science is also leading scientists to investigate the possibility of cell-based therapies to treat disease, which is often referred to as regenerative or reparative medicine. There is genuine scientific excitement over the concept of using the body's own cellular building blocks to regenerate damaged or ageing organs. Stem cells are one of the most fascinating areas of biology today. But like ...
Stem cells are becoming a powerful new tool for replacing damaged or destroyed tissue in different parts of the body. There are two basic types, embryonic stem cells and adult stem cells. Stem cells, found in the body, can engender exact facsimiles of themselves. They have the capacity to construct a number of specially designed cells such as heart muscle cells, liver tissue cells, brain tissue cells, etc. Embryonic stem cells are extracted from aborted fetuses or embryos left over from in vitro fertilization. Adult stem cells are found in both children and adults. Adult stem cells can be utilized for a circumscribed number of other kinds of cells while embryonic stem cells are able to individualize into over two hundred types of cells. Embryonic stem cell research is so controversial because society is judging whether or not taking stem cells from days old embryos is immoral, or if doctors should look past the cons and do what is necessary to eventually preserve many lives.

There has been a debate about stem cell research since 1998 when the research teams of James A. Thomson of the University of Wisconsin and John D. Gearhart of Johns Hopkins University School of Medicine announced the isolation of human stem cells (Farrell). But before anyone should take a side, one must know what a stem cell is. A stem cell is an unspecialized cell characterized by the ability to self-renew by mitosis while in undifferentiated state, and the capacity to give rise to various differentiated cell types by cell differentiation (Stem Cell). There are three types of stem cells in the human body: embryonic, hematoietic, and adult (Lee). Hematoietic stem cells come from the blood of the umbilical cord (Lee). Adult stem cells are taken from various parts of the body, like bone marrow or tissue. Embryonic stem cells come from a blastocyst, which is a an eight-celled human embryo (Farrell). The blastocyst must be disassembled to obtain the stem cells (Farrell). Researches prefer to work with embryonic stem cells because they are undifferentiated cells, which means they can transform into any cell type in the human body. But there is controversy with embryonic stem cells because the blastocyst has the potential to become a fetus.
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.
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.
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
To be able to comprehend the importance of the discovery of stem cells, it is crucial to understand the terms and definitions that go along with the topic of stem cells. A stem cell is derived from a human embryo, scientists are able to keep these stem cells alive and have them replicate after extraction. A human embryo comes into existence from the joining of one sperm and one egg, after the embryo is formed it begins to replicate itself. After ab...
Science can be described as the pursuit of innovation, advancement and opportunity. Stem cells have offered scientists and the world a new doorway to treat diseases and help millions. The major, significant discovery of stem cells is their ability to differentiate into any cell type which can help rebuild damaged organs. One thing for certain is that these cells brought huge controversies over their uses, how scientists should obtain them, and if the embryos should be used at all on the basis that they should be held on the same morals as humans. Although with these monumental issues at hand, researchers have not given up hope that one day these stem cells will be widely accepted and be used for the benefit of the people.
