What are stem cells?
Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and differentiating into a diverse range of specialized cell types.
Why are they of interest to medical researchers?

Stem cells are unique in their ability to divide and regenerate themselves in people's bodies. They can replace damaged or destroyed tissue, as opposed to having organ transplants, as there aren't many donor organs. Scientists could program stem cells to become a desired cell. That way, people can heal from serious injuries easily.

Ethical implications of stem cell research

Stem cell research is at the centre of a raging controversy due to its ethical implications. Although few debate the potential marvels that mastering stem cells could provide by way of medical advancements in the treatment and prevention of life threatening diseases, many object strenuously to the measures being taken to reach that goal. Proponents of embryonic research argue that a blastocyst is only a cluster of 150 cells, and does not possess even the nervous system required to biologically qualify as a human being. For the people whose moral beliefs state that human life begins at the moment of conception, embryonic research is simply unacceptable, especially since adult stem cell therapy has already proven to have potential in treating diseases such as diabetes, acute renal failure, sickle cell

Clone: Stem Cells. Stem Essay

According to scientists from New York stem cell foundation laboratory, the first prosperity in using the cloning technique which it was on dolly. Stem cell has a lot of benefits which able to treat diseases, such as diabetes and spinal cord injury by change the old with new one. Some researchers show that SCNT can use to change the genetic material of an egg cell with the DNA from a mature cell like a skin cell. In 1996 the first animal cloned was Dolly. After that, scientists did a lot of researchers…

Pluripotent Stem Cells

Induce Pluripotent Stem Cell Induction of Pluripotent stem cells is one of the most controversial topics that many Biology scientists want to discover. In the article titled “Induction of Pluripotent Stem Cells from Adult Human Fibroblasts by Defined Factors,” scientists do the research on how to develop the pluripotent stem cells from somatic cells (Takahashi et al. 2007). Induction of Pluripotent Stem cells is the process that reprograms human somatic cells into pluripotent stem cells so that they…

Essay on Stem Cells

Stem cells are special cells that have not decided what they are yet. Stem cells can form any body part, including body parts that normally don't regenerate. If you can control the stem cells and inject them then you can do things like re-grow kidneys or a liver, or make better bone and skin repairs. Or more scientifically put: Stem cells are cells found in most, if not all, multi-cellular organisms. They are characterized by the ability to renew themselves through mitotic cell division and…

Stem Cell Essay

I have chosen to do my research of news articles on stem cell research, an often controversial, but necessary topic. In my first article, from, The New York Times, titled, “Cloning and Stem Cell Work Earn Nobel,” by Nicholas Wade, I learned that stem cells generated by the induced pluriponent cells (IPS) will enable replacement tissue to be generated from a patient’s own cells for use against a vast variety of degenerative diseases. Though this breakthrough is still in the distant future…

Essay on Stem Cells

The Incredible Cell Stem cell research is relatively new but offers the potential to yield a cure for some of the most tragic diseases of our world. Stem cell research was initiated in the early 1900s. Since then, stem cell research has expanded significantly as researchers search for cures, but it has also generated huge public resistance to using embryonic human cells for research purposes on moral and ethical grounds. In this research paper, stem cells will be explained and an argument…

Then you are a lot like stem cells. Our bodies contain many specialized cells that carry out many specialized functions, these cells are called differentiated cells. In contrast to this, a stem cell is undifferentiated where it’s role in our body is not yet determined. Stem cells are undifferentiated…

Essay on Stem cell

Stem Cell Research Stem cells were originally discovered in 1981, scientists found a way to derive embryonic stem cells from early mouse embryos. Another breakthrough discovery was made in 1998 that took stem cells from human embryos and grew them in a laboratory. Stem cells have the possibility to save hundreds of thousands of lives, scientist work every day experimenting and learning about the affects of heart disease, discovering answers to questions that may save lives, and being able to apply…

Stem Cell Research

Stem cells have the great potential to be very beneficial to scientist in finding treatment for diseases like Parkinson’s Disease (PD). This research has so much potential because they have only just begun working with stem cells. With the great potential that stem cells hold there is still a large barrier between the promise of stem cells and the realization of their use. Looking into human stem cells, scientist are able to come up with new ways to create neurons that produce dopamine from our stems…

Stem Cell Research

Introduction Stem cells are undefined cells with the potential to become any type of specialized cells. Stem cells can be derived from embryos, fetuses, and even adult cells. Stem cells can be used to replace tissue that is damaged, or even destroyed. If used to its full potential stem cells can help to fight the effects of aging. Stem cells draw in a mass of controversy and issues on many fronts both scientific, and moral. Stem cells could eliminate the problems thought to be unsolvable, and better…

Stem Cell Research

Stem Cells are the blank cells that can be inserted into an organism that would ultimately help produce more cells. There are people who believe that Stem cells should be used for medical purposes and those who believe it should not. I believe that Stem cells should be used for medical procedures because it helps make more cells. It also helps cells repair damaged tissue. Not only do I believe that stem cells should be used in Medical purposes but EU as well. ( http://www.stemcellresearchfacts…
