Snow Day #2. First post: attendance posting by 3/17, completion and participation postings by 3/20
Hello, rather than put us behind I am going to have you do the stem cell assignment I was going to have you do next week. It will work out fine. This assignment is worth 40 points. There are three parts for this assignment. 1. Watch the video Understanding Embryonic Stem Cells (Douglas Melton, Ph.D.)- not hyperlinked either copy the url below ad put in the address or go to youtube and type in the name of the video youtube: https://www.youtube.com/watch?v=nYNBNZJ8Xck_ 1b. Find two or more additional sources to use for completing the assignment. 2. Complete the written assignment (I would recommend typing it in a word document and then copying it into the response: 30 pts Include:

Hello everyone. Can you believe we have another snow day? This is an interesting assignment and applicable to your system project as it asks for how stem cells and other new types of medical advances apply to your system.

What is a stem cell? A stem cell are undifferentiated cells. These Cell are able to turn into specialized cell types. Stem Cells come from two sources Embryonic and Adult.

Nice job. You mention some really good points about the difference between embryonic and adult stem cells. We are already using adult stem cells for some therapies. It is pretty amazing how many blood stem cells circulate through our body.

all very well said. and i agree with your opinion as far as the ethical debate goes!

1. A stem cell is a cell that has the ability to develop into any cell type. They are capable of cell division and can become tissue and organ cells. They mostly serve as a internal repair system.

The embryonic stem cells come from unused IVF embryos. They do get stem cells from umbilical cords as well but those are umbilical stem cells.

I think that they should do more research with stem-cells. At this point they don't even really know just what these cells can really accomplish. Very interesting to think that Stem-cells could be the answer to many unanswered questions.

I agree that there should be more research on stem cells. However, I found it interesting that embryonic stem cell research is subject to the govenment's rules. In the United States, the use of federal funding for new lines of embryonic stem cells was banned in George W. Bush's administration. President Obama reversed that decision when he took office. We're not sure if the Trump administration is going to have a positive or negative impact on the stem cell research. Other countries such as China have relatively relaxed embryonic stem cell research policies compared to US or other European countries and its government gives top priority to stem cell research. It's interesting to see how science is heavily impacted by government's policy and social consensus.

What are stem cells?

Interesting point about the embryonic cells able to be become tumors. There is a great book about cultured cells call the Immortal Life of Henrietta Lacks. It isn't stem cells but they have cultured cells that are used in most laboratories that were taken from Henrietta nearly 50 years ago.

I find it really interesting to learn about the HeLa cell. Her cells have been used for various research to provide vaccines and cures for many diseases. It's surprising to see that her cells have been commercialized without the permission of the Lacks or her family. I can see that some people might feel that they should be compensated for their contribution if their cells or tissues have been used for medical or scientific research. The question is how should we regulate the use of human tissues in medical field?

agreed that the embryonic stem cells can possibly cause tumors and I'm pretty sure he said they can be rather large in size.
