Essay Rough Draft

“I was able to spar the other day. I felt good. My leg feels healthy,” said Cormier. “In like the third, fourth week is when the stem cells really start to take shape, really start to help the healing process. I’m in week five now. Man, I feel pretty good. I don’t have much pain in it. I just really have to control myself as I go forward because you want to go in head first.” Stem cells have been tested on for many years. Stem cells are cells that are unspecialized cells and they divide into specialized cells. The there are many types of stem cells, the three main types are: Embryonic stem cells, non-embryonic stem cells or adult stem cells, and induced pluripotent stem cells (iPSCs). Through years of research scientists …show more content…

According to NIH scientists are just beginning to understand the signals inside and outside cells that trigger each step of the differentiation process. The internal signals are controlled by the gene’s of the cell, while the external signals that cause differentiation include chemicals that are secreted by the neighboring cells, physical contact with neighboring cells, and certain molecules in the nearby environment or in this case the nearby microenvironment. Scientists are currently still doing research about stem cells. Currently they are trying to answer two questions. Those questions are: Why can embryonic stem cells proliferate for a year or more in the laboratory without differentiating, but most adult stem cells cannot; and what are the factors in living organisms that normally regulate stem cell proliferation and self-renewal? Even though they’ve been studying for years they still don’t know everything about stem cells. This shows how complicated it stem cells are. Answering the questions from earlier would be a great scientific breakthrough, hopefully someday these questions do get answered. Another question that they should try to answer could be can you manipulate the cells to differentiate to specific cells. Eventually scientists will learn more about what causes stem cells to differentiate. Someday they might even be capable of manipulating the cells to differentiate into specific organs and

For example, Alzheimer’s disease is a disease that is caused by brain cell death. Alzheimer’s does not have a cure, and the only treatment for it is medication that will slow the death of cells. However, if embryonic stem cells were used, they could replace and, theoretically, stop the death of brain cells, which would in turn, halt the disease. So overall, this treatment could dramatically benefit patients struggling through diseases like Alzheimer’s, Parkinson’s, cancer, and diabetes. Furthermore, the increase of quality of life for these living people is more than worth the possible destruction of a cluster of

I think the author though could've used more facts so she could back up her opinion. Something I learned from this article was that if you culture two different cell lines on a soft substance they can inherit or acquire stem cell like qualities. I think other information that would help me understand this topic better is a deeper explanation on the topic the article gave a brief explanation. Three words that i didn't understand were; progenitors, pluripotent, and PNAS. Progenitors means the parent or creator of something, it did go with the context I was reading.

Over the years, there have been many controversial issues surrounding medical research, but one of the most arguable topics of all time is the use of embryonic stem cells. Some individuals believe that extracting stem cells from unborn babies will be useful to create new medications or, in most cases, help regenerate damaged cells. Although, many people disagree with the process scientists use to obtain these stem cells. By continuing embryonic stem cell research, scientists are denying an unborn child the chance to live, they are not letting nature take its intended course, and they are not adhering to the religious or moral beliefs of many people.

One source said, “...human cells could end up in the brains of the animals. That raises the prospect that “this will somehow give the animal a human consciousness, human mental capabilities”... In addition, some scientists and bioethicists fear the stem cells could create human eggs and sperm in the animals.” The stem cells used in chimera could make the animals partly human, reason being their human mental capabilities. Also, theses cells could become part of the reproductive system and, for example, could lead to a human being born from a pair of mice.

Stem cells can provide so many benefits, but we need stem cell research to learn and produce all of these benefits. The first argument to advance in stem cell research is the cell's ability to cure medical diseases. Stem cells can create a variety of specialized cells that are the cause of diseases and losses. These cells include brain and tissue cells.

Embryonic Stem Cell Research is Vital The embryo a very early life form, so early it’s not really even a child yet; inside of it embryonic stem cells have form. These cells carry great potential for medical advancement. With them many lives can be saved, that is why the research needs to continue. Embryonic research is worth the loss of some embryos; the embryonic stem cells gained through the process can and have reduced the suffering of many, can be used to create insulin which could one day lead to a cure for diabetes, and can also grow new human organs.

The other main source of these stem cells are adult stem cells (they can be found in all of us), they can be found in various places such as brain, blood, blood vessels, muscles and skin and liver. These cells are cells to be used in case of emergency, they stay in the mentioned parts of the body for years without dividing, they are activated and start dividing in case of disease and injury to substitute for the lost cells in injury or disease. The stem cells can replace the diseased cells by healthy cells, they can be used to see how they develop into differentiated cells which can help doctors understand how some diseases develop. They can also be used to test “drugs” before they are used on people to evaluate whether the “drug is safe or

Stem cells have the potential to cure specific diseases such as Parkinson 's, Alzheimer 's, Diabetes, and Cancer. A few years ago, you could only get stem cell transplants from specific doctors, But as of 2015 there are 170 clinics that can do the procedure. The way that they implant the stem cells into the patient 's body is by putting the cells straight into the bloodstream or by inserting the cells into the patient 's bone marrow. They extract all of the stem cells that they need and then they take out the patient 's dead stem cells and put in the donor 's healthy stem cells.

This process provides a safe alternative to embryonic cells, as the stem cells did not produce tumors. Adult stem cells are also being found in more tissues than ever thought (Stem cell Basics). This would allow many different uses of the adult stem cells, as they can only form certain major cell types of a tissue or

Most people in our society, no matter what level of education that they may have, have heard of the cloning, specifically the cloning of Dolly the lamb, and have some notions regarding the idea of cloning humans. "The successes in animal cloning suggest to some that the technology has matured sufficiently to justify its application to human cloning" (Jaenisch et al.). However, not every agrees that human cloning is a something that should be put into practice (Hoskins). There generally seem to be two basic divisions on this issue: those who find it inappropriate and unethical, and those who find it a reasonable and necessary step in the progression of scientific research (Lustig).
