Stem cells are the basis of development in organisms such as humans, plants, and animals. Stem cells come from many different areas in our body and they develop at different times throughout our lives. An example of this are embryonic stem cells that are only available during our early stages of development, meaning that these type of stem cells only exist when we are still developing as a baby. Another type of stem cells are ones that also develop during the early stages of our lives but the only difference is that they remain in our bodies until we die.
According to the International Society for Stem Cell Research, stem cells are categorized into two characteristics. First of the two characteristics is that they are empty cells that are capable of renewing themselves through the process of cell division, this ability is called self-renewal. Second, under certain conditions they can be persuaded by other factors in the body to become specific tissue or organ cells with special functions. Sometimes, stem cells regularly divide to repair and replace worn out or damaged tissues, such as the gut and bone marrow. In certain organs, such as the heart and the pancreas, they will only divide under unique conditions.
Aside from having certain characteristics, stem cells also contain some specific behaviors. One the behavior is called pluripotent and this is exclusively found in embryonic stem cells, this means that they can generate all of the body’s cell types but cannot generate support structures like the placenta and umbilical cord (“Stem Cell Facts” 2). We can only obtain this type of stem cell from a hollow ball consisting of 150 to 200 cells called the blastocyst. As stated earlier, embryonic stem cells are foun...

...her is not ethical, and it is as if we are playing God. Choosing who gets to live or not. People believe that embryos are still considered to be humans because although they are not a human right now, they will grow up to be one and that if you take the embryonic stem cells away from the embryo, it will not evolve into an adult. Stem Cell research is all based on perception, what people think the value of a life is. Either respect life for what it is, or do something about it to make one’s self feel better. The argument here though, lies in if they use stem cell to feel better, they are messing with human life. If people did not research stem cells, people would not find anything to relieve the suffering caused by diseases like Parkinson 's. Some people say that the pros by far outweigh the cons and ethical issues but it is all about people’s perception on human life.

- Stem cell research has been around for many years. What are stem cells. They are the base cells of our bodies. Cells that make up our organs and tissues are the cells that come from stem cells after fertilization. Stem cells have the ability to replace cells that are lost and can repair injured tissues. They are made up of two characteristics which are their capacity to self-renew and differentiate. Self-new is when they the cell divide and create more stem cells. Differentiate is when the stem cells turn in more specialized cells that make up our tissues and organs.... [tags: Stem cell, Cellular differentiation, Stem cells]

- This year’s internship will need students to work with a scientist using stem cells. The stem cells will be used from embryos created during the in vitro fertilization. This may alarm some of you, but these embryonic stem cells were going too be destroyed by the companies because the couples didn’t want them or they had been to long in the laboratories. Instead of having them be destroyed, we will use them for improving the quality of life of human beings. As the interns you will have the chance to be part of something extraordinary....

- Stem Cell Research What if there was a more efficient way to cure non-communicable diseases other than surgery. Stem cell research could be answer to this. Although, the benefits of this research are high there is controversy when it comes to this topic. Mostly, ethical issues such as the use of embryonic stem cells and cloning. There are many different stem cells used in stem cell research: embryonic stem (ES) cells, induced pluripotent stem (IPS) cells, and adult or somatic stem cells. “Embryonic stem cells are grown in the laboratory from cells found in the early embryo” ("Types Of Stem Cells And Their Current Uses")....

- Stem cells have several potential applications. Stem cells can be used to study development by helping us to understand how a complex organism develops from a fertilized egg. Some of the serious medical conditions such as cancer and birth defects which are lead by abnormal cell division and differentiation will have new therapy dealing with stem cell research. Stem cells have the ability to replace damaged cells and treat disease of extensive burns, leukemia (a cancer of blood forming tissues) and other blood disorders....

- In the first ten days after conception, several hundred stem cells already multiplied and a baby will be formed. These tiny stem cells produced osteocystes, cardiac muscle cells, and neurons. They are the building block for all 260 types of cells in our bodies. Even through adulthood, stem cells are produced by our bodies to replace old cells. However, we do not produce enough stem cells to heal a spinal cord injury or fight cancerous cells. Through research, scientist can manipulate embryonic stem cells that would treat autoimmune diseases, heart diseases, spinal cord injuries, and much more....

- Stem Cell Research Pluripotent stem cells are true stem cells with the potential to make any differentiated cell in the body (Stem Cells). These cells can be harvested in a myriad of ways, but the most well known for their controversial reputation are those that come from reproductive techniques and unwanted products of reproduction. In Embryonic stem cells, excess embryos produced during in vitro fertilization procedures are used and Embryonic Germ Cells can be isolated from the precursor to the gonads in aborted fetuses (Stem Cells)....

- ... They are less mature than adult stem cells but more mature than embryonic stem cells (Freedman 10). There is a lot of research being done about stem cells today. Scientists try to figure out what tissues can be made from stem cells and how to reproduce the cells best. A lot of this research is done in vitro (out of the body) in labs. Learning how stem cells change into different cells can give us the ability to stimulate stem cells in labs to form tissue. It could lead us to being able to change stem cells in the body to specific cells (Freedman 12).... [tags: disorder, cells, change, osteoblast]

- Embryonic stem cells are being researched worldwide in an attempt to provide treatment for some degenerative diseases and human injuries. Although research is still being undertaken, these stem cells are providing a positive outlook on potential treatments however; as a potential human life is involved, is the use of embryonic stem cells to treat human diseases justified. Embryonic stem cells are obtained from the human embryo, which is developed from a fertilised egg (NIH, 2010). These embryonic stem cells are known as being pluripotent; the ability to develop into virtually any cell within the human body (Science Daily, 2014).... [tags: Stem cell, Embryonic stem cell]

Bush, Aug. 9, 2001 Stem cell research is not new but only recently has it become widely known to the public because the benefits of the technology are coming closer to reality; the field of stem cell biology is advancing at an incredible pace with new discoveries being reported in scientific literature on a weekly basis. Scientists first announced a method of growing embryonic stem cells in a laboratory in 1981, but the cells were from a mouse.... [tags: Embryonic Stem Cell Research Regulation]
