Remarkable potential of stem cell research essay

Clearly this shows that more funding was given for stem cell research in general than for embryonic stem cell research itself, which has yet to show any promise at all. In some adult tissues, such as bone marrow, muscle, and brain, discrete populations of adult stem cells generate replacements for cells that are lost through normal wear and tear, injury, or disease.

Although it has been eight years since the initial derivation of human ES cells, it is an open question as to the extent that independent human ES cell lines differ from one another.

Karl Marx thought that conflict arose out of social class, while contemporary conflict theorists include other groups such as gender, age or race. This impact is likely to begin well before the widespread use of ES cells in transplantation and ultimately could have a more profound long-term effect on human medicine.

It is surprising, for example, that mouse and human ES cells appear to be so different with respect to the molecules that mediate their self-renewal, and perhaps even in their developmental potentials.

It is clearly the beginning of life, but has not yet begun to specialize its cells. Human somatic nuclei were transferred into human oocytes nuclear transferwhich previously had been stripped of their own genetic material, and the resultant nuclear transfer products were cultured in vitro to the blastocyst stage for ES cell derivation.

Cells resembling both oocytes and sperm have been successfully derived from mouse ES cells in vitro. Genetic Manipulation of ES Cells Since establishing human ES cells inscientists have developed genetic manipulation techniques to determine the function of particular genes, to direct the differentiation of human ES cells towards specific cell types, or to tag an ES cell derivative with a certain marker gene.

Because of important species-specific differences between animal and human hearts, however, drugs that are toxic to the human heart have occasionally entered clinical trials, sometimes resulting in death.

He and his team were the first to come up with a technique that would isolate and transfer stem cells. Yet we remain remarkably ignorant about the molecular mechanisms that control pluripotency, and the nature of this remarkable cellular state has become one of the central questions of developmental biology.

Thus, it was difficult to culture single-cell fertilized embryos long enough to obtain healthy blastocysts for the derivation of ES cell lines.

The Moral Issue of Human Embryonic Stem Cells

In some organs, such as the gut and bone marrow, stem cells regularly divide to repair and replace worn out or damaged tissues. Feelings about conflict, while normally expressed about stem cell research are voiced, can also be concealed for various reasons. Those against embryonic stem cell research were happy with the decision because they believed that the research was unethical and immoral.

Therefore, ethical conflicts raised in the development of this epoch-making event. Indeed, basic research enabled by human ES cells is likely to impact human health in ways unrelated to transplantation medicine. Once a set of defined culture conditions is established for the derivation and culture of human ES cells, challenges to improve the medium will still remain.

Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells for as long as the person or animal is still alive. What is important to realize is that when stem cells are taken from an embryo or fetus, the embryo and fetus are destroyed Tesar,p In the 3- to 5-day-old embryo, called a blastocystthe inner cells give rise to the entire body of the organism, including all of the many specialized cell types and organs such as the heart, lungs, skin, sperm, eggs and other tissues.

Each of the cells blastomeres of these cleavage-stage embryos are undifferentiatedi.

Embryonic Stem Cells

Scientists also realize the potential that could come out of all types of stem cell research with government funding.According to the National Institute of Health, stem cells are cells that have the remarkable potential to develop into many different cell types in the body.

Serving as a sort of repair system for the body, they can theoretically divide without limit to replenish other cells for 4/4(1).

Stem Cell Research Recently, there has been quite a lot of controversy among the media regarding the topic of stem cell research, its pros and cons, but what is this controversy really about?

The term “stem” cells can be compared with another much known term: “differentiated” cells. Read this free Language Essay and other term papers, research papers and book reports. The Moral Issue of Human Embryonic Stem Cells. According to Rickard (), the benefits of stem cell research has a remarkable potential to fulfil the first principle by alleviating and eliminating suffering and pains of patients or human life; meanwhile.

The Remarkable Abilites of Stem Cells; The Remarkable Abilites of Stem Cells. Stem Cell Research Essay Words | 5 Pages. and are remarkable because of their potential to grow into a variety of different kinds of cells within a body.

Common in fetuses, and more rare in adult animals of all kinds, stem cells can be manipulated in.

Stem Cell Basics I.

When a stem cell divides, each new cell has the potential either to remain a stem cell or become another type of cell with a more specialized function, such as a muscle cell, a red blood cell, or a brain cell. Advances in stem cell research The history of this cells’ research is for more than 5 decades.

In the earlythere was the discovery that the bone marrow has at least two different types of stem cells.
