Stem cells are cells that
have the extraordinary ability to develop into many different cell types in the
body. They either are taken from adult tissue or from a dividing zygote in a
petri dish. There has been a lot of controversy regarding stem cells whether it
is ethical or not to experiment with them and to use them in the medical field.
I think that stem cell research should be pursued because it has the potential for
scientists to learn about human growth and cell development, potential for
finding treatments and cures for diseases, and the potential to contribute to
regenerative medicine and therapeutic cloning.
Understanding stem cells and their unique attributes and
control can help teach scientists about human’s early development. With more knowledge
of stem cells and how they grow and divide, scientists can learn more about basic
biology and can to detect the abnormalities that lead to many diseases. Stem cells
have the potential to be the one of science’s most powerful tools of all time.
only can stem cell research help scientists understand normal development but
it can also aid in circumstances such as diseases and birth defects. For
example, cancer is thought to be a result from abnormal cell proliferation and
differentiation, with research scientists can figure what goes wrong in stem
cell division and what leads to cancer to help find ways to prevent the changes
or create effective ways to treat them with targeted drugs. Stem cells are
already used in cell therapies for treatment of some cancer types, but this use
is still small in the scheme of diseases affecting humans today so with more research
the possibilities could be endless.
stem cell research can contribute to regenerative medicine and therapeutic cloning.
In some tissues, stem cells can play a vital role in regeneration because they can
easily divide and can keep replacing dead cells. For example, a patient may have
damaged tissue in their heart and it may be possible to stimulate the growth of
healthy tissue by transplanting laboratory-grown stem cells into the patient’s heart.
In the past, scarring of the heart tissue has been irreversible but with continued
research it is possible for that to no longer be the case and save patient’s lives.
