Imagine waking up from a tragic accident that left you paralyzed from the neck
down, would you have hope that you could ever recover? What if there was research
that the use of stem cells could lead to potential treatments and cures? According to the
National Institute of Health, stem cells in certain organs, have the ability to divide into
other cells that are used to “repair and replace worn out or damaged tissues” (NIH).
Although stem cell research raises ethical concerns, it should be legalized due to the
possibility of medical advancements and cures of numerous diseases.
Stem cell research benefits because it will help enlighten scientists’ knowledge in
the biology of human development which could be helpful to future findings. In “Stem
Cell Research and Applications” by Audrey Chapman, Ph.D., stem cells are stated to be
“unspecialized cells that are thought to be able to reproduce themselves indefinitely
and, under the right conditions, to develop into mature cells, e.g., nerve, skin, pancreas,
with specialized functions” (Chapman). They are different from normal cells because
they are unspecialized, meaning that they are not committed to a specific cell or tissues
function. Another thing stem cells can do that ordinary cells cannot do is divide for long
periods of time. If the stem cell divides and is still unspecialized, then the cells can
usually repair themselves. Also, if the stem cell becomes a specialized cell, it could
potentially become a number of different cell types.
There are three main types of stem cells. They are adult, umbilical cord, and
embryonic stem cells. Embryonic stem cells can become almost any cell type in the
body, and adult stem cells are restricted to the t...

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
“Through the isolation and manipulation of cells, scientists are finding ways to identify young, regenerating ones that can be used to replace damaged of dead cells in diseased organs. This therapy is similar to the process of organ transplant, only the treatment consists of the transplantation of cells rather than organs. The cells that have shown by far the most promise of supplying diseased organs with healthy cells are called stem cells.” (Chapter Preface)

...ns of a morally questionable nature. It is necessary that our practices remain ethical and that we uphold the value of a human life, as this is the cornerstone of human society. Embryonic stem cell research is one such operation that forces scientists, policy makers, and the larger society to define what constitutes a human life and to find an answer to the crucial question: Is it morally acceptable to violate the rights of a human life for the for the sake of medical progress?
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.
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 have the ability to transform into any kind of cell. These cells can divide and also replenish other cells in the body, such as muscle cells, brain cells, red blood cells, or they may just simply remain as stem cells. Stem cells are able to replicate even after long periods of dormancy. They naturally repair damaged tissues and can be experimentally induced to work with particular tissues and organs (NIH, 2013).
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 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).

Those who favour stem cell research are optimistic about the continued developments in stem cell research will open doors to many breakthrough discoveries in biomedical science. The scientific and ethical questions arise as rapidly as the reaching of milestones in stem cell research. There are two main types of stem cells, namely embryonic stem cells and adult stem cells. Adult stem cells are undifferentiated cells in our body. But they have restricted-range of cells that they can further differentiate. On the contrary, embryonic stem cells have the ability to differentiate into nearly two hundred cell types in the human body, called pluripotency. The process of harvesting embryonic stem cells involves destruction of embryos (Mooney, 2009).

Yet there are also some major benefits that have already arisen from cloning. Stem cells are somatic cells in a primitive state, where they can grow into many different types of cells. In an explanation for some of the benefits of cloning, the following example is given, “These cells [stem cells] could then be used for medical purposes, possibly even for growing whole organs” (Utah University).
