Go to the following websites and read the background information about stem cells:

https://www.bedfordresearch.org/stem-cell-research/stem-cell-research/stem-cell-faqs/
On the Bedford website, read all of the provided information and click on ALL of the embedded video links listed there (Stem Cells- What is a Parthenote Stem Cell, What are Induced Pluripotent Stem Cells, Stem Cells- What are Nuclear Transplant Stem Cells).

Question 1
Describe what stem cells are and where they come from. Be sure to include details that indicate you read the information on both websites.
Question 2
Describe what Stem Cell Therapy is. Be sure to include details that indicate you read the information on both websites.
Question 3
List at least one scientific advantage and one scientific (not ethical!) disadvantage involved in using embryonic stem cell therapy. These should not be related to cost or ethics, but rather should detail what technical challenges exist.
Question 4
Is using these cells unethical? Why or why not?
Question 5
Should the government continue to use tax dollars to fund embryonic stem cell research? Or should this kind of research be restricted to private research institutions? Why or Why not? (Consider that under the Bush administration, tax monies could only support research conducted on already existing embryonic stem cell lines- a policy which was recently reversed under the Obama administration.

 

Sample Solution

Stem cells are the body’s raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells. There are several sources of stem cells: Embryonic stem cells. These stem cells come from embryos that are 3 to 5 days old. At this stage, an embryo is called a blastocyst and has about 150 cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs. Adult stem cells. These stem cells are found in small numbers in most adult tissues, such as bone marrow or fat. Compared with embryonic stem cells, adult stem cells have a more limited ability to give rise to various cells of the body.

It is fascinating regards to the osmosis of pieces into lumps. Mill operator recognizes pieces and lumps of data, the differentiation being that a piece is comprised of various pieces of data. It is fascinating to take note of that while there is a limited ability to recall lumps of data, how much pieces in every one of those lumps can change broadly (Miller, 1956). Anyway it’s anything but a straightforward instance of having the memorable option huge pieces right away, somewhat that as each piece turns out to be more natural, it very well may be acclimatized into a lump, which is then recollected itself. Recoding is the interaction by which individual pieces are ‘recoded’ and allocated to lumps. Consequently the ends that can be drawn from Miller’s unique work is that, while there is an acknowledged breaking point to the quantity of pi
