Stem cell research is a topic almost everybody in the world has a viewpoint on. Many view the issue of stem cell research and stem cell therapy as morally wrong and a crime against humanity, others view the study of stem cells as the next step in modern science. What are stem cells? Stem cells are non-specialized cells that have the capability to mature into more specified cells to help with certain functions or diseases. Cells are the basic building blocks of the human body and these tiny structures compose the skin, muscles, bones, and all of our internal organs. Cells are necessary for our body to live, there are over one-hundred specialized cells in our body. Stem cell research should be supported due to the plethora of potential benefits to the medical community and the human race as a whole.
Medicine today is moving quickly to make more effective cures for diseases and new techniques for treating illness. One of the new techniques being practiced today is stem cell therapy. Stem cell therapy can be defined as a group of new techniques, or technologies, that rely on replacing diseased or dysfunctional cells with healthy, functioning ones. ( Langwith 23) These new techniques are being used to treat a wide variety of disorders such as Parkinson’s Disease and Lou Gehrig’s Disease.
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...

...tself, and can differentiate to yield the major specialized cell types of the tissue or organ. (Langwith 192) The greatest advantage of adult stem cells is that it’s usually possible to use a person’s own stem cells which is the safest stem cell option for people. (Langwith 192)
The adult stem cell may help cure diseases ranging from diabetes to Parkinson’s disease. Although adult stem cells have the potential to cure certain diseases, they are limited in number, where as the embryonic stem cells have an abundance of versatile cells. Regardless of the type of stem cells, stem cells are the future of modern science and should be pursued due to the potential benefits it may bring.

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
Stem cell research: Stem cells are cells that are at an early stage of development. This means they have the ability to turn into any type of cell in the body. Some research is currently focusing on whether stem cells can be turned into muscle cells and used to regenerate damaged muscle tissue (American Thoracic Society Consensus Statement, 2004).
In 2001 scientist attempted to create a cloned human embryo, they had consulted all the necessary sources before getting the “ok” to begin “creating”. Then they had to find a female subject to donate eggs. To start the process of cloning they need to use a very fine needle and get the genetic information from a mature egg. Then they inject it into the nucleus of a donor cell. The female donors were asked to take psychological and physical tests to screen for diseases and what not.

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.
Stem cells are a type of unspecialized cells that can revive themselves through the process of cell division (Abdel-Salam and Oma, 2011). They have a phenomenal potential to differentiate into other specific cell types in a living organism. These cells can also be activated to turn into organ-specific cells or tissues with defined activity but only under specific experimental set-up. Stem cells have the ability to remain as they are or divide further to renew deteriorated and damaged tissue cells. Recently it has been discovered that stem cells can be used to treat Alzheimer’s disease, but still a lot of clinical trials are being conducted to find a specific government approved treatment.
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...
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.
The study of stem cells have brought about many recent ethical questions and been a topic in many recent ethical debates. What is all the talk about? What exactly is stem cell research and why does it raise so many ethical questions?

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).

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).
