So we are studying stem cell research in class
A sperm and an egg are introduced
in vitro(in a dish) and are allowed to grow to a developmental stage before
implantation in the uterus. Those that aren’t used are thrown away. A scientist
takes one of these embryos and about 5 days after developing the embryo divides
into the trophectoderm and the inner cell mass(ICM). This ICM is extracted and
used to conduct research. This is the embryonic stem cell.
The allure of this cell to many
scientists is that these cells can divide amongst themselves and become any
cell in the body. Theoretically you could replace tissue and connections (CNS
and PNS). You could test drugs on heart tissue for example without needing an
actual heart and complications arise when trying to apply animal research to
humans. You could eliminate that.
One of the major challenges is that
it’s really hard to do and science hasn’t come that far yet. Another challenge
though is an ethical one and all this was to build up to this ethics part. An
argument against stem cell research is that you are killing life. The egg and
sperm have the potential to be a human and by doing this you extinguish that possibility.
On the other hand people say the egg was going to die anyway when its discarded(as
a side note an egg that is fertilized in vitro has zero chance of being a
person until it’s implanted in a uterus). On the other hand if someone is on
death row is it ok to harvest his organs before he dies since he was going to
die anyway? On the other hand the stem cells can be used to not only test new
drugs but to also cure a number of diseases: parkinsons, huntigtons, alzheimers
and ALS(lou gehrigs). This could SAVE many people not to mention the many
people that are waiting for donors and matches. Does the end justify the means?
They could just grow themselves a new kidney or what not. Many advances in
science and the things we enjoy now have come at a price many never consider or
think of.
So, my question is this: is stem
cell research ok?
