Dear talked about earlier in the letter. There

minister of health, in this letter I’m going to explain why using induced
pluripotent stem cells is good, but also why induced pluripotent stem cells
should not be used. In this letter I’m also going to explain what they are, how
they can be used and why they are used. This letter is going to be facts, but
also about my view and what I think about stem cells.

is a stem cell? A stem cell is a cell that has no specific job. This means that
these cells have the potential to become any cell in the body. For example, blood
cells or skin cells. These cells have the potential to become even more
specialised in one specific area of the body. This means that these types of
cells are the foundation of our body. Stem cells have two mayor properties. The
first one is that they have the ability to self-renew. This means that they can
make exact copies of themselves. The second function is that they can
differentiate. This means that they transform into specific cells which I
talked about earlier in the letter.

are three types of stem cells, with all different properties. The first one is
tissue-specific stem cell. These cells can also be called adult or somatic stem
cells. These cells differentiate from the other types of stem cells, because
these are more specialised than other types. These cells are located in one
specific tissue. Then when other cells die, these types of stem cells have to
replace the dead cell. These cells are found deep in a tissue, for example, the
bone marrow in our body. The second type of stem cells is embryonic stem cells.
These cells are also called pluripotent stem cells. Pluripotent means that they
have the ability to become many different types of cells as long as they are
specified to do so. These stem cells differ from tissue specific stem cells
because the embryonic stem cell have the potential to become any type of cell,
but the tissue specific cells can only become more specified within a tissue.
Embryonic cells are the first cells in a human body to be made. It happens when
an egg is fertilized. As the cells multiplies a blastocyst is formed. This is a
ball of approximately 150-.200 cells. The last type is called induced
pluripotent stem cell (IPS). These stem cells are tissue-specific stem cells
that have been reprogramed by scientists to become embryonic cells. These cells
are needed when many cells have died and there are not enough stem cells to
replace the dead cells. They do this by “making” embryonic cells and the
exposing them to an environment where the stem cell can become a specific cell.
For example, skin cell or liver cell

There is both good and
bad things of using IPS cell. The question is if there are more good things
than bad, and if that is the case should we use IPS cells more often. Let’s
first take a look at the pros in using IPS cells. If we could use IPS cells it
would give us a good insight in our body. IPS cells can be used to make
treatments against different diseases. By using IPS doctor can make more
personalised treatments. For example, Parkinson’s
Disease, Alzheimer’s Disease, Heart Diseases, Stroke and Diabetes (Type 1), Spinal
Cord Injuries, Replace or Repair Damaged Organs, and stem cells may play a
major role in cancer. These are all diseases that could help be cured with IPS
cells, but what could be the negative sides by using IPS cells? The negative
sides are that; some people argue that this research could in the future lead
to “bad” knowledge. “Bad knowledge” means that people in the future will know
how to clone and that would not make people feel safe, because people could
make armies out of cloned people. Another thing is that people say that you
should not mess with human life or that we should not try to play God. There are
more ethical issues, but they are all have the same point and it is that it is
not really ethical to take embryonic cells from a fetus.

think that stem cell research is important. The important part about IPS cells
are that they can cure a lot of diseases and that is what counts. I can agree
on that it would not be very nice if scientists new how to clone, but the
question is if it is ever going to go that far. I think that the biggest
problem right now with stem cells is that it is only a few people that can get
this type of medical help since this method is kind of new.


pluripotent stem cell is one of the three types of stem cell, which is a cell
that has no specific job. IPS cells being one of the most talked about area in
science, are cells that are embryonic cells taken from fetuses or
tissue-specific/ adult cells being reprogramed into embryonic cells. The
question is, should people be able to do this? I think that scientist should do
this, because I think that the positive outweigh the negative things about
using IPS cells. The good things are that they can help curing some diseases
and the bad stuff that some people are questioning if it is ethical enough. So,
my conclusion is that I think that it is much more worth to save some one’s
life that thinking about if this method is ethical or not.
