Brian, I thought your paper was great. It was filled with all the right details and examples. In the last paragraph you wrote about your own personal experience with your accident. I think adding that to your paper really made it that much better. That must have been scary thinking you might not be back to 100% of yourself. Im glad everything is back to normal for you. But it definitely is a different way to look at things and imagine how other people must feel going through all those different diseases!

I really like how in depth you got with the embryonic stem cell. The way you explained it made it seem incredibly miraculous, it made it captivating to read and learn more than I thought I actually knew before. It helped me capture an image of stem cells flourish, and assisted me to a realization of how important stem cells really are. Before this assignment I never even knew how important stem cells actually were, but knowing now that I couldn't live without them makes me realize how enthralling to the subject I should be, even though it doesn't do much to know about it, (unless I had some sort of cancer, disease, or serious problem, and needed references on what was causing it), it's still significantly interesting to know what's going on in our bodies and how they are still properly functioning as we continue to live.

Brian, the last paragraph in your paper about an accident that happened a couple years back putting you in a hospital for some time is a perfect addition to your paper. Putting a personal story into your paper gives the reader the other side of the debate. Most people have never been in a situation like yours where they’re sitting in a hospital bed being unable to walk from a spinal cord injury. Your personal experience and the side of the debate that you described about how someone with a crippling disease might feel gives the read a different perspective from the one of the sides.

Brian, it was interesting to see a very personal view point. Not many have experienced something so terrifying and uncertain. I am curious, do you think that stems cells that would have been available to you if the situations were worse case scenario?How long does stem cells take too see results? I did not come across the answers to these in my research.

At the time no and I'm pretty sure that's still the case. As far as I can see its still in the research phase. For people with complete spinal cord injuries (vs mine which was incomplete thankfully) stem cells have the potential to regrow spine that would be forever injured. That suggest there's hope for someone with an irreparable spine to actually grow those cells back which is pretty amazing. For the record most spinal cord injuries with swift treatment do recover often.

Without stem cells none of us would be here today. Stem cells are mother cells that can become any type of cell in the body. One of the main things that a stem cells do are multiply while maintaining the potential to develop into other types of cells. Stem cells can become cells of the blood, heart, bones, skin, muscles, brain and so on.

The medical benefits in your paper stood out to me a lot, the crazy things happening inside our bodies is just so astounding to me. It sounds so horrific to hear that it destroys the human embryos in the process of creating new ones, the procedure sounds so painful, but really we have no idea it's even happening. There's so much information to remember about our functions in our body so most of it can be really perplex to some of us, that's why it's great reading the studious papers of others gathered knowledge because some could add other information you didn't know about which makes it super eye catching.

Stem cells are a cell that is used for not only the purpose of creating new organs (such in the embryotic case) but also for the special function of being able to replicate cells and heal or maintain already existing organs. They are a cell that is able to form differentiated versions of itself that genetically change due to internal, and external factors.

Stem cells are important for all living organisms. They are capable of developing into many different cell types throughout early growth. In addition, stem cells serve as an internal repair system to help replenish other cells of the body. They also renew themselves through cell division and replace damaged tissues. When stem cells divide, each developed cell may either stay as it is or become another type of cell such as a muscle cell or brain cell.

Stem cells are cells that are remarkable in nature, they have the ability to develop into many different types of cells throughout the body. Stem Cells can be thought of as the bodies internal repair system because the cells divide to repair or replenish the damaged cells. When the stem cell divides it will either remain a stem cell or it will become a more specialized cell such as a muscle cell, brain cell or even a blood cell. Stem cells are distinguished by two characteristics, they are unspecialized cells that are capable of renewing themselves by a process called cell division even after long periods of inactivity. Under the right physiologic circumstances stem cells can also be induced to become a tissue cell or an organ specific cell for example cells will regularly divide to repair or replace damaged cells or tissue (NIH 2016)

We have heard a lot of controversy around the subject of whether or not it is ethical and reasonable to invest and expand the resources and use of stem cell research. Before one can fully stand on one side of this issue or another, we must first know the basics of what stem cells actually are. Let’s take a closer look at the definition of stem cells. These are a very special and important type of cells. They can be defined as a cell that is not a specific type of cell already such as a tissue or organ, in other words, it has not been differentiated. Also, stem cells can renew and replenish themselves. These fascinating cells have a remarkable ability to develop into many different cell types in the body during the early stages of life and growth. You could even call them the “primary colors” for all cell make up and are crucial and completely fundamental for normal growth and development. Stem cells can change into different cell types and are not necessarily exact clones of the parent cell. The possibilities for greatness are vast.

Katie, Your paper is filled with really good information and you really went in depth with everything you wrote here. Giving examples and opinions along the way. The section you wrote about the debate is strong and i couldn't agree more when you said, " it has and always will be a touchy ethical and moral debate". I dont think this argument will ever come to an end and everyone will always have a strong opinon about it!

Katie, the last paragraph in your paper about ethical debates perfectly describes and covers all the controversy about stem cells. Describing the debate to becoming a slippery slope hits the nail right on the head, the possible down hill spiral that could happen from the debates is a scary thought. The people who favor the use of embryonic stem cells and believe that the fetus inside the mothers whom is not a “a human” I believe are totally incorrect. I believe that every fertilized egg is and should be considered a human. Although I still believe in the practice of abortions I think that mothers should be able to decided if they can leave a pregnancy if fathers can leave the pregnancy. The debate on stem cells will be an ongoing debate that may lead to the slippery slope logical fallacy of if one thing happens another will happen.

Jared, thank you for your comment. Usually I try to keep my personal view point on debates in these things. However, I must ask you a question in response to your post. If you consider an embryo human, how would abortive procedures not be considered murder? When a pregnant woman is killed, why is it considered a double homicide?
Brian

Yes, the moral and ethical debate is not going to be an easy one moving forward. There's two completely polar opposite schools of thought on this and I can only hope science can find a way around it like maybe obtaining embryonic stem cells without actually destroying the embryo or even better ways to use adult stem cells. All those benefits without all the controversy would be AWESOME!

I really loved reading your paper because you made a lot of really great points, especially in your last paragraph.The question, "When, then, can we say an embryo becomes human?" really got me thinking more about this topic than I already was!

Oh wow! I had no idea that there was research in determining and choosing WHO your offspring will be. This is both fascinating and terrifying. What countries are doing work in this aspect? Is this being practiced in the world now or is this just in theory and in labs?

Great paper! I agree with your opinion on the controversy surrounding stem cells. There are two very different sides to this controversy and asking questions like those are important.

I completely agree with you that the ethical debate on stem cell research is purely over the issue of embryotic stem cells, and it's all derived from what people do and don't see as life. Meaning that to some people they may see the blastocyst as a small bundle of cells, where others may see a baby.

Stem cells are cells capable of becoming a different type of cell, to heal/replace cells that have died or become weak. These cells have the ability of renewing themselves and functioning as cells that help grow/divide/heal areas of the body that need it.

I'm glad you noticed that the big difference of the cells is that the embryotic ones are completely undifferentiated meaning they can not only heal any tissue, but they have the ability to heal tissues that normally wouldn't.

I had a nice little table explaining the differences between the Embryonic stem cells & Adult Stem cells, but when I copied and pasted my response it got a little messed up so here are the differences.....
