Arguments - FOR

1. The advantages of using embryonic stem cell for liver disease are greater than the cost
of using the human embryo. The cells are able to be grown in laboratory environments and
are able to grow into a large amount of different types of body tissue.
Although embryos have a great amount of use and potential, are not of the same value
as human lives itself, thus, have more advantageous use being used to cure current
living human diseases rather than to grow out into potential humans. “Approximately
18% of zygotes do not implant after conception…” (http://bootstrike.com/Genetics/
StemCells/debate.php), from this data, it can be inferred that much more human
embryos die from this rather than donated to laboratories for experiments. Some people
argue that embryos are not the same as humans, and that an embryo can only be
classified as a human after its first heartbeat, which happens when the brain starts to
develop activity.
IVF (in vitro fertilization) always produces large amounts of unused embryos, which many
of are discarded. Using them for scientific research is a much more efficient and practical
use, rather than have them wasted.

2. Embryonic stem cells are a better alternative as opposed to adult stem cells. In a
developing embryo, embryonic stem cells make up a substantial portion of the embryo,
whereas useable adult stem cells are found in very little quantities in mature adult
individuals. Adult stem cells do not divide as quickly as embryonic stem cells, which
could possibly make it harder to create large amounts of the cells, and could also not
have enough cells ready at any immediate time. Embryonic stem cells also have a higher
plasticity level, which allows them to be used in treatment for more types of diseases.

3. The use of embryonic stem cells could assist in the recovery of many physical, mental
and genetic diseases. An example of this is that veterinary surgeons have, by injecting
stem cells from the dog's fat into it's damaged areas, cured dogs with arthritis and
given them the ability to walk again. Embryonic stem cells can also help in research, as
sometimes, when drugs and medicines need to be tested, they are tested on humans and
animals, and can potentially result in detrimental effects to the subjects body. These kind
of tests can be experimented on tissue created from embryonic stem cells in a laboratory,
so consequences will not matter.
