Essay On Cloning

The two main types of stem cells scientists use are Adult and Embryonic Stem cells. The embryonic stem cell is the first type of stem cell scientist’s deal with that are obtaining from the embryo. Most embryonic stem cell are taken from embryos that develop from eggs that have been fertilized in vitro fertilization then donated for research purposes with informed consent of the donors. (stemcell... ... middle of paper ... ...scover new cell lines, but are working towards changing that. Stem cells definitely have the ability to have a large impact in the science and medical fields.

Scientists and researchers are gathering human embryos to further study and test stem cells and some people don’t agree with this. The end result of using embryonic stem cells is someone being able to walk again, someone remembering the names of their children, and someone being able to say that he beat cancer. Stem cell research is beneficial to society and should be accepted into labs all around the world. Only the most pristine of labs get to receive stem cells to research and test. In the United States of America, most of these labs are usually at universities and institutes (Crosta).

The Benefits of Stem Cell Research Stem cells are considered “master cells” with the ability to divide for indefinite periods in cultures and can be manipulated and transformed into any type of cell in the body. The most common use would be the generation of cells and tissues that could be used to either create organs or tissues to be used in transplantation and to treat many diseases and disabilities. There is a great difference of opinion surrounding stem cell research; conservatives and pro-choice activists are highly against further research, but the tremendous advances in health care and President Bush’s recent decision to fund more research, have made the future of stem cells seem much more promising. In every ground breaking scientific topic there seems to be controversy, and stem cells are no exception. Stem cell research is so controversial because the best source of stem cells are derived from human fetal tissue.

On April 28, 2011 - the United States Appeals Court overturned the rule of a federal judge because of several issues that emerged with stem cell research being funded by the government. Although, the science of human embryonic stem cell is in its initial stages - there is much hope for scientific advancement due to the ability for human embryonic stem cells to grow into virtually various kinds of cells  Favorably, advocates for stem cell research and pharmaceutical companies strongly believe that stem cells may pave a way to discover new methods of treatment for devastating ailments; such as, Leukemia, Alzheimer’s disease, Heart disease, Parkinson’s disease and diabetes- a prospect that is inspiring to both scientists and those who are seeking cures for themselves and family members. In contrast, numerous pro-life advocates are against federal funding for stem cell research because of the method in which these stem cells are extracted. In addition, several other groups argue that the federal government has abandoned more substantial as well as promising and less controversial adult and cord stem cell research. Instead, the government has dedicated a majority of their funding in favor of the more popular and controversial stem research.

As technological advancement grow, scientists begin to speculate the realistic doing of human cloning, as this happens opposing groups and organizations raise their voice against it and create the question whether scientists should be allowed to clone humans, the promise of cloning at any level can revolutionize the world, and change it for the better, but are we are not ready for human trials. If successful, cloning can have a lot of positive technological advancements that would help humanity. Dolly, the first cloned mammal, inspired many scientists to speculate a new era in cloning technology and raise hopes for future probability in which human cloning was possible. At the center of the controversy, surges the closest thing to a clone that lives a healthy and regular life, identical twins. The promise of cloning at any level can revolutionize the world, and change it for the better, but are we really ready for human trials?

Studies on stem-cell research point toward a solution to this deadly problem. With efficient use of stem cells, many diseases and medical problems could be solved. Stem-cells are very young, specialized cells. Usually coming from a human embryo, they have the ability to develop into more specialized groups of cells or tissues (“Stem Cells: A Primer”). As of 2001, scientists could develop stem-cells into more than 110 different types of tissues, such as blood, brain or heart tissue (Robinson).

One of the most controversial topics in the field of biomedicine has been the research of embryonic stem cells. Stem cells are extremely fascinating to what they can do they have the potential to develop into many different cell types in the body during early life and growth. In many tissues they serve as a sort of internal repair system, dividing without limit to replace other cells as along as the person is still alive. When stem cells divide they could become specialized cells such as muscle cells, red blood cells, brain cells, and etc. their unique generative abilities, stem cells offer a new potential for treating diseases such as diabetes, and heart disease.

"Stem cell therapies are not new. But when scientists learned how to remove stem cells from human embryos, both excitement and controversy ensued" (The Stem Cell Debate: Is It Over?). Excitement over the array of new possibilities, and controversy over the moral and ethic implications, of stem cell research. Quite possibly, stem cells could bring human life invulnerability. Thus, the requisition of stem cell research is imperative to elongating the existence of human life.

Using spare embryonic cells in order to continue valuable scientific research is a superior alternative to discarding this rich source of research material. In fact, most of the embryos used for this research have passed the date when they can even be used in fertilization t... ... middle of paper ... ...e are currently no treatment options. Clearly, embryonic stem cells provide an amazing leap forward in the medical fields, and have the potential to save lives. As the need for new cures to life-threatening illnesses rises, scientists are increasingly looking towards stem cell research to provide the answers they need. Despite the heated controversy that surrounds this research, the results of countless experiments have had proven success.

Since the advent of embryonic stem cells, scientists all over the world have tried to come to terms with the endless possibilities these cells hold, harnessing them to create synthetic organs, and cure previously incurable diseases. However, embryonic stem cells face much opposition in terms of the ethics involved in obtaining these cells from both embryos and mothers, as well as the possible health risks associated with them. Even so, this field shows a great deal of promise, and should not be disregarded solely due to these issues. Human Embryonic Stem Cells (hESCs) have a rare senescent ability to divide infinitely (Rippon & Bishop, 2004) and differentiate into any cell type (are pluripotent). As the name suggests, they are derived from excess embryos or blastocysts from IVF treatments (Fig.
