Stem cell essays

Scientific research has had a fair share of debates over the course of its existence.

What are stem cells

Through extensive research and major advancements in technology over these years, decades, and centuries we still have no answer to our own questions. But overall, it is still unclear whether this and other types of adult stem cells are as efficacious as originally proposed. A relative of a friend of yours had a spinal cord injury after a bad car accident. While various arguments surround this debate, the main point of controversy is the source of stem cells used and the method with which they are obtained. Embryonic stem cells are easier to obtain; they have a greater cell growth, otherwise known as proliferation, capacity; and they are more versatile. Therefore, their use in treatments could be fraught with problems, at least until a clearer understanding emerges regarding the signals that turn them on and off in their growth cycles. They also play a key role in the repair and Adult Stem Cells Vs.

A relative of a friend of yours had a spinal cord injury after a bad car accident. Ithaca; London: Cornell UP, Although, the benefits of this research are high there is controversy when it comes to this topic.

Supporters of embryonic stem cell research argue that the research is justified, though it requires the destruction of an embryo, because of the potential for developing cures and preventing unavoidable suffering.

Then, they are rearranging into a hollow ball known as blastocyst and surround the blastocoel which is a fluid-filled cavity. For an example, stem cells will help scientists better understand human life.

But if he had gotten the support and funding for stem cell research, his story might have ended differently.

Therapies such as this will continue to be discovered with the support of stem cell research.

Uses of stem cells

In addition, you will know some of the pros and cons researches about Stem-Cells. Stem cells can also be used to study labor defects so that future birth deficiencies can be prevented or reversed. This article offers a general overview of stem cells, their potential for extending life and improving its overall quality, and some thoughts on the role of health educators with regard to professional and lay audiences. The Loss of Future Life Problem holds that it is unethical to take the lives of future humans by destroying embryos for research Tobis The current belief is that amniotic fluid contains a mixture of embryonic and adult stem cells. This bill gave scientists in America some government funding but not as much as other countries that are making huge leaps and bounds in the cloning world already have Beeman Differentiate is when the stem cells turn in more specialized cells that make up our tissues and organs A second controversy surrounding stem cell research is the apparent groundbreaking outcome of studies performed by a research team in South Korea. A major bonus of this approach is the ability to take the cells from the patients themselves and therefore reduce the likelihood of transplant rejection. This is a problem that will require a solution if embryonic stem cell research is to be the basis for future therapeutic medicine. Stem cells are template cells found throughout the body that can grow to become cells with specialized functions.

However, a controversial solution to this issue has been around for awhile-stem cells. However, the ethical question still arises, "do the ends justify the means?

Embryonic stem cells

In most situations, both principles can be satisfied. The first successful production of embryonic-like induced pluripotent stem iPS cells was published in by Japanese stem cell research scientists who used a microscopic needle to directly inject the genes necessary to reprogram an adult somatic cell into an iPS cell These stem cells can renew themselves and reproduce to form all cell types of the body. After a sperm fertilizes an egg, the cell they form is known as a zygote or a totipotent cell. Stem cells can become cells of the blood, heart, bones, skin, muscles, brain etc. There is a lot of positive outcomes that can come from researching this technology of stem cell research because many people all across the globe would benefit from it. Supporters of embryonic stem cell research argue that the research is justified, though it requires the destruction of an embryo, because of the potential for developing cures and preventing unavoidable suffering. Ohio had previously proposed funding dedicated to adult stem cell research. Before medical physicians and others are able to actually work in the field they must take an oath to always remember the ethics that they are taught. Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research. A stem cell is an immature cell that can help reproduce different types of cells throughout the body. With this in mind, embryonic stem cell research should receive greater government funding so that continued progress can be made. Why is so much controversy over the stem cells? The blastocyst is composed of three parts: the trophoblast or outer surface, the blastocoel or inner cavity, and the inner cell mass found inside the blastocoel which is composed of stem cells. Stem cells are also described as unspecialised because they are not yet advanced to perform an exact function.
