Embryonic Stem Cell Research What if there was a way to cure previously in-curable diseases with the help of something in the very first stages of human life, but thousands upon thousands of lives had to be taken to perfect the use of this material? That is exactly what is happening with embryonic stem cells around the world. Pro-life activists, who originally organized to stop the abortions of unborn fetuses, were most angered with the process of actually destroying an embryo solely for research purposes. However, scientists, such as Dr. Andrew Yeager of the University of Pittsburgh, argue that embryonic stem cells are the future of medicine. ââ¬Å"This is really where, I think, so much of biomedicine is going to be going in the twentyâ⬠¦show more contentâ⬠¦There are other less controversial methods of obtaining stem cells, however none of those methods seem to retrieve stem cells with the same ââ¬Å"vitality and versatilityâ⬠as those taken from embryos (Reaves). Umbilical cord blood has proven to be effective in some cases. Keone Penn, a fifteen year old from Atlanta, Georgia, was cured of his sickle cell anemia by receiving a stem cell injection. Although stem cells from umbilical cord blood are high proportioned compared to are own bone marrow and circulating blood (Dr. Andrew Yeager), they are still pluripotent, meaning that they can develop into many of the 220 cell types in the human body, but not all, therefore limiting their usefulness. Another and most obvious alternative would be to take stem cells from already grown adult stem cells. However, scientists around the world soon discovered that there were many setbacks to using adult cells. The first is that adult stem cells are already specified, meaning that if a biomedical technician were to take out a blood stem cell, it could only be used for the replacement of blood cells. Embryonic stem cells, on the other hand, are not specified, or have not yet developed into a certain type of cell. The process is controver sial because of the cloning that takes place in a culture. First, the nucleus from an unfertilized egg is extracted. The nucleus contains the chromosomes of the cell, and in this case, the chromosomes of the egg. An egg alone onlyShow MoreRelated Paper761 Words à |à 4 Pages In the 1790s members of the industry in both Paris and London were working on inventions to try to mechanise paper-making. In England John Dickenson produced the cylinder machine that was operational by 1809. Although useful for smaller enterprises, this lacked the large scale potential of the machine resulting from the invention of Nicholas-Louis Robert in Paris, which had a more complicated incubation period. The last of the early improvements to this machine were financed by the Fourdrinier brothersRead MoreOn Behalf of Paper1685 Words à |à 7 PagesFor centuries, people have read and learned on paper.

The Empress of China at that time loved books and wanted to have a lot of them made. At the time everything was written on silk scrolls which were extremely expensive and time consuming to make. She wanted something cheaper and easier to use and so she asked one of her servants, a gentleman by the name of Tsi Lun to come up with an alternative.

The main reason why I detested writing papers, was because I considered my English horrible. English is not my native language and learning it was difficult in my opinion. Especially, when as a child the only place where you could speak English was at school. Other than that, the only language I was allowed to speak at home was Spanish. Throughout the years I eventually got the hang of it, and at the beginning of fourth grade, I was placedRead MoreCharacteristics And Quality Of A Paper1062 Words à |à 5 PagesChoosing the right paper is more complex and it requires more work than just picking any expensive sheet and keeping your fingers crossed. To choose the right paper, you should not choose one based on the highest quality available, or the most expensive one.

To choose between the func tion and quality of a paper is not very easy. It isRead MoreSelf-Reflective Paper 838 Words à |à 3 Pagesfixed.

A lot of knowledge was gained from writing these papers and I was able to compare and contrast the disciplinary writings and notice what makes each of them stand out. Reflecting back on these individual papers helps to express what I have learned. The first paper that was written was the humanities essay. The humanities essay helped to provide
