Hello, this assignment and posting will be an attendance grade and a classwork grade. Post your essay on or by 10/22, and respond to 2 peers on or by 10/28. Please make sure you complete it on time and to the best of your ability because it is for a lot of points.
This week's assignment has a lot of detail, you will need to read each part carefully. Each of the videos included should be hyperlinked but if you have an issue opening them then just copy the URL and paste in the address to access the video. This is also an assignment that counts heavily (50 points)because of how much I am asking you to do. Here we go... Preparing for the essay: Part 1: Watch the video Understanding Embryonic Stem Cells (Douglas Melton, Ph.D.) (www.youtube.com/watch?v=nYNBNZJ8Xck) Part 2: Find two or more additional credible sources about stem cells to use for completing the assignment. Remember to note your sources as you go to add them to your reference page. Credible sources are .edu, org, or another reputable source, no blogs or wikipedia. Part 3: Complete the written essay - in-text citations and reference page required for all information that comes from a source other than yourself Include the following information in your essay:
Part 5: Respond to the paper of peers (10 points) My grading checklist: 1. Essay is grammatically correct and formatted as an essay without bullets: 10 points 2. Essay addresses all the required information with detail and appropriate support: 15 points 3. References are credible i.e. a .edu, .org or other reputable source: 5 points 4. In-text citations are properly formatted and there are only two or less direct quotes that are approximately seven words or less: 5 points 5. Reference page is properly formatted and in alphabetical order with a minimum of three references: 5 points 6. Responds to peers with detailed comments that illustrate that they read their peers essay. These comments include connections between their paper and yours, connection to life experience, acknowledgement of new information, added details that build on comments in the essay, etc: 10 points Total points: 50 I told you it was a lot. I hope you find this interesting and get a lot of information out of this assignment. Remember there is a stem cell aspect of your final project so you can cover two things at once with regards of your research. Helpful hints about in-text: 1. Direct quotes need to have quotation marks and should be limited to around seven words. 2. There should not be more than two direct quotes in your paper. 3. Paraphrase information in your own words but if the majority of the information comes from a source a citation is needed. 4. Check out this website for some examples of in-text citations: Pellissippi State Community College Library (durhamtech.libguides.com/c.php?g=464476&p=3175461) Helpful hints about a reference page: 1. Use owl Purdue to help with formatting your references (owl.english.purdue.edu/owl/resource/560/01/) 2. Your reference page should be in alphabetical order based on the first letter of the reference.

I think of stem cells as the queen bee of cells. Without a queen, we wouldn’t have the others. “Stem cells are the body’s raw materials.” (Mayo Foundation, 2019) These are cells from which all other cells are made. Stems cells divide to form more cells called daughter cells in the body or a lab (Mayo Foundation, 2019). Stems cells are unspecialized. Daughter cells can become new stem cells called self-renewal stem cells. They can divide and renew themselves over a long time (NIH, 2016). They also can become specialized or differentiation cells. These cells are cells that have a specific function within the body (Yourgenome, 2019). A differentiating cell can be found in the nervous system and skin. It can also be found in blood, heart, and muscle. It can be found in the pancreas, liver, stomach, and lungs. Differentiated cells are found everywhere in your entire body. Stems cells also have the potential to become specialized or differentiated cells.

Adult stem cell's role in a human body is to maintain and repair tissue. Adult stem cell research started more than 60 years ago. In 1950, researchers discovered two kinds of stem cells in adults in their bone marrow (NIH, 2019).

The ethical debate centers on embryonic stem cells. In 1998, scientists learned how to remove stem cells from a human embryo. There was excitement due to the cell's potential to cure human diseases. The moral implications of destroying human embryo are and forever will be the controversy around the globe. In the United States, there are laws that prohibit the creation of embryos for any kind of research purposes (University of Utah, 2019). Scientists receive embryos from fertility clinics with consent from the donors. Guidelines were enacted in 2009 by the National Institutes of Health. Theses guidelines defined embryonic stem cells and how they are used in research. It also includes guidelines on donation. The stem cells are donated with informed consent from donors and live and grow in test tubes or petri dishes in laboratories (NIH, 2019).

I also wanted to mentioned that I learned the term pluripotent where adult stem cells can be altered to have some of the characteristics of embryonic stem cells.

April, I am in complete agreement that the video on stem cells featuring Dr. Melton was fascinating. It's very powerful to get a glimpse into another person's passion. I appreciated your aspect on how the research of stem cells should be continually evaluated and evolving.

I enjoyed reading your essay, you broke down each step from a zygote to a blastocyst and how it needs to be fertilized. My favorite part about your essay is the comparison you made with the seasons and how everything is born then dies off with each passing season. Comparing the leaves with its change in color explaining how stem cells kind of work in the same way. Explaining that our stem cells slow down and age in the renewal/regeneration process leading us humans to age.

Hi Alfred! Loved the paper. My thoughts..... I liked how you used the analogy in the beginning relating to the cycle of life that nature goes through just like our bodies. I loved your sentence, "Regeneration is a wonderful gift by nature". And I liked how you nicely you tied it back in at the end. I also like your sense of humor in paper. I definitely don't do that in papers. I think it is something that can lighten up such a heavy complicated topic. So for the future, I will try and see if I can slip something lighthearted in my writing. Your sense of humor comes out when you talk about the possibility of a persons arm regenerating and growing back in and saying that could be creepy. Then again, anything is possible. Maybe not now, but I believe the future has endless possibilities and limb regeneration might even be one!

Alfredo, your essay is very organized and easy to read. The information is clearly stated and well cited. I didn't know that trees in rainforests that experience a winter have a longer life span. I do know that there is something very special, as you mentioned about the renewing of life in the spring. I feel that it makes me appreciate the warm weather more to have a true winter. I grew up near Portland Oregon were snow in the winter is rare. I have come to love and appreciate the true four seasons that we have here in New England.

Stem cell research is a fascinating science that helps us understand better how the bodies of animals and humans grow and develop. By harnessing the power of stem cells, scientist could help us discover cures for disease and create the ability to repair or even replace damaged organs. Wouldn’t it be amazing if we could cure diabetes by having a stem cell injected into our pancreas to create new insulin cells? To understand how some of this might be possible we need to understand the following: What are stem cells? What types of stem cells are there? What are the medical benefits of each type of stem cell? And what are the drawbacks of using stem cells? This paper seeks to answer these questions.

The Medical benefits are vast with the use of embryonic and adult stem cells. By doing research on stem cells, scientist can better understand how disease happens. They could provide stem cell therapy by injecting stem cells into a diseased or damaged organ or tissue to repair or regrow new tissue. Or instead of transplanting organs, they could grow stem cells in a lab to become specific types of cells like heart muscle cells, or nerve cells.

Hi Nicole Casey! I enjoyed reading your paper. The sentence I liked in the beginning that you stated, " Wouldn't it be amazing if we could cure diabetes by having a stem cell injected into a pancreas to create new insulin cells?" I so do hope this happens one day. It seems like everyone I know either has diabetes or knows someone that has it. From your paper I learned the definitions for totipotent, multipotent, and hematopoietic stems cells. I also read about how a patients body may reject a embryonic stem cell. I read this doing my research and think I forget to add this to my paper.

Nicolle, your paper was very interesting to read. I was fascinated by your research on macular degeneration and how the research has resulted in how different cell types in the retina function together. The idea about replacing damaged RPE cells in the eye with cells grown in a lab is intriguing and I can understand how being able to see into the eye to observe what is happening and also the ability to compare the patient's other eye would be a huge benefit to this research. I thought about how dangerous it could be for cells to migrate to other areas of the body and become something that they shouldn't when Dr. Melton showed the slides of the embryonic cells that had spontaneously become groups of beating muscle cells. You won't want that in your eye or your pancreas! That was another benefit you pointed out, the eye being fairly autonomous, which would hopefully keep this risk at a minimum. Great research Nicolle.

I apologize that I haven not yet posted my essay. Despite that, I wanted to comment on the video and all of your amazing and educational essays. Stem Cell research turned out to be an extremly thought-provoking topic with some very curious ethical complications.
