Stem Cell Research
Imagine a world where every day scientists create human beings, cultivate them for a week, and then
destroy them. This scenario sounds vaguely familiar to the creation of Frankenstein in Mary
Shelley's book Frankenstein. The difference between the creation of Frankenstein and the creation of
human beings is that the latter has already become true as scientist are creating and destroying
embryos. Scientist today even in the United States are creating human embryos and then destroying
them when performing stem cell research, but the government does not fund these scientists.

Would you hold back your government's money from funding stem cell research if it was your child

I understand that conservatives believe life begins at conception; thus, stem cell research is murder.
However, there are several thousands of embryos each year discarded from left over in–vitro
fertilization banks and aborted fetuses that could be used for stem cell research. These embryos
are already destined for destruction, so why not use them for a better purpose? They can be used
to save many lives. I do not agree with abortion; however, since abortion is legal in the United
States, some good should come out of this terrible act. If the embryos are merely discarded, no
good has come from their terrible end of life. Yet if the embryos destined for destruction are used
for stem cell research, they could provide some other people with the blessing of a healthy life.
You could think of these embryos as little Jesuses giving their lives so that others have live a
blessed life.
Since there are thousands of embryos left over from in–vitro fertilization banks and aborted fetuses,
it is unnecessary for scientists to create embryos solely for the purpose of destruction. Scientists in
the United States are now creating embryos and destroying them; however, it is not being done by

Embryonic Stem Cells
"Embryonic stem cells...are in effect, a human self–repair kit," (Christopher Reeve, activist – Larry
King show). For the advancement of science, stem cells are infinitely valuable, especially when
considering all the potential applications in the field of medicine. Stem cell usage is a very
controversial topic, because most people think of abortions, cloning, and other negative topics when
they hear the term stem cell.
However I think those thoughts are because they don't understand what a stem cell is, where it
comes from, or its monumental possibilities that could greatly benefit the medical field.

Pluripotent cells could help with things like re–growing a kidney or leg ligament, if yours has been
damaged.
Pluripotent stem cells can create the possibility for a renewable source of replacement tissues and
cells, which means a large number of diseases could be cured and treated.
This includes debilitating diseases, Parkinson, Alzheimer, Leukemia, Down syndrome, muscular
dystrophies, retinal degeneration, spinal cord injury, stroke, burns, heart disease, diabetes,
osteo–arthritis, rheumatoid arthritis, brain repair, skin for burn victims, and maybe even cancer and
diabetes (stemcellnetwork.com).
Finally Multipotent cells can be found in children and adults, in blood, bones, and etc.
They only have specific functions, and can no longer do anything besides those functions. However,
Multipotent cells are still useful in replacing or replenishing any damage cells that are similar to the
specialized type, which means less people waiting on organ donors. That would be a tremendous
accomplishment, because thousands of people die each while waiting for an organ transplant. (MRC).
When scientists completely learn how stem cells work, they could be able to create tissues needed
to treat patients with various types of sickness and disease. For example, Birth defects and cancer
arise do to abnormal cell specialization and cell division. If scientists were to understand how to
manipulate these

Essay on Embryonic Stem Cells Research
Embryonic stem cells research is a very conflicting subject in the United States. Some people think
that it is morally and religiously incorrect as they are killing a human life at the first stage of life.
While some think it is ok because the human life to them starts at the fetus or when the fetus can
feel pain. In this paper we are going to discuss the total aspect of embryonic stem cell research: how
the government takes play in the study of embryonic stem cells, how embryonic stem cells have

have a better understanding of embryonic stem cells and why some people may benefit from it, as
it may help to cure some diseases. Maybe we can come...show more content...
People who oppose embryonic stem cell research see the destruction of the embryo as murder, no
matter how much good it would cause to society. In November 2007 researchers like Shinya
Yamanaka and James Thomson found a new method to used human skin cells. These were similar
to using embryonic stem cells that turn out to be pluripotent, in this case they were not destroying
the embryo. Researchers are trying to please the religious groups while still trying to find cures for
diseases. If we keep finding gratifying ways to keep everyone content, image how many lives we
can save. As stated in the article Hyun, I. (2010). The bioethics of stem cell research and therapy.

and cultured in 1998 by donated couples no longer intending to us them for themselves. From that
point in time is started a never ending controversy with researchers and religious groups. Some of
the people's concerns are towards human cloning and the mixing of animal species. There have yet
to be any word of human cloning or any type of mixing of human and animal species, but there has
been cloning done on mammals. A group of Scottish scientists clone a sheep back in 1996, her name
was Dolly. Dolly later died of a lung infection at age 6. After this the Bush administration took

Research on stem embryonic stem cells
We live in a world where genetic sciences have gone beyond laws, and past the imagination. We
have come to a point where we don't know anymore what is right, and what is wrong. We have to
decide. In fact, studies are made on embryonic stem cells that for now have the purpose to better
our overall health. These stem cells are extracted from extra IVF embryos; they are used and
destroyed. While it's true that this research could cure serious illnesses as Parkinson's, Alzheimer's,
and orphan diseases for example; however, it's also true that ending a potential life is immoral and
illegal. We could definitely find an alternative to the embryonic stem cells to develop the science. An

No one gave us the right to take advantage on him and then kill him, and as noted in
experiment–resources.com: "humans should not be trying to play God". Fortunately, most of the
leaders in the world share this same opinion. During long years, governments of developed
countries weren't certain of what to do about this subject. They took different positions depending
on the techniques that were used: if the embryo was an extra IVF embryo or if it was created on
that purpose; and on the consequences the researches would have on him. Today, according to
www.bionetonline.org , most of European countries such as France, Germany or Spain do not allow
embryonic stem cell researches. In United States, during Bush's administration, during 8 years,
federal funding were not given for embryonic stem cells researches. Indeed, in a letter to the House
Members, NIH Director Zerhouni said: "the president's position is still predicated on his belief that
taxpayer funds should not sanction or encourage further destruction of human embryos that have at
least the potential for life". Now, according to an article in About.com: U.S Liberal Politics titled:
Pros& Cons of Embryonic Stem Cell Research" President Obama have lifted the federal funding ban
for embryonic stem cell research". But still, laws are very clear, and even if using embryonic cells is
allowed, credible sources such as Wikipedia declare that "the creation of a human embryo

Stem Cells Essay
Stem cells are a large focus of study in today's biomedical world. They are cells that exist in an
undifferentiated state, and transform into differing tissue types depending on what the cells
surrounding them are. The different types of stem cells have the ability to repair many classes of
damaged human tissue. However, only one type of stem cell promises to regenerate virtually any
class of tissue. This is the highly controversial embryonic stem cell (ESC). Unfortunately, there is a
dark side to the ESC. To obtain these cells from embryos will ultimately kill it. By definition, the
acquisition of the ESC includes performing an abortion. This has created a great stir in the public
world, where abortion is such a hot topic that...show more content...
Effectively, the mice were cured. Soon, other scientists found they were able to repeat this
phenomenon in other laboratories around the world.
Multiple Sclerosis is not the only disease that scientists have the ability to cure. In some isolated
cases, juvenile diabetes has been added to the list of cured diseases (Goldstein n.p.). This,
however, is not the only disease scientists believe they will be able to cure. Stem cells show
promise to have the ability to cure diseases including but not limited to Alzheimer's Disease, Lou
Gherig's Disease, Hodgkin's Disease, and nearly every form of cancer. With research allowing the
discovery of cures to an ever–growing list of diseases, many scientists are devoting much of their
time to push for more support from the people as well as the government to continue their research.
The medical world has also stepped in to petition for support. Scientists and doctors alike understand
the potential of stem cells, and the number of lives they can save, although, they also understand the
necessity of the people's support. Until Americans understand the vast potential of stem cells, these
scientists and doctors will continue to perform their research and medical procedures without
drawing undue attention to their activities. However, they strongly believe in what they are doing,
and refuse to stop saving lives.

Essay On Embryonic Stem Cell Research
For years, scientists and doctors have been looking for ways to prolong human life. Medicine has
evolved over the years; surgeries have become less invasive and treatments have become more
effective for diseases such as Smallpox, Malaria, and Measles all of which have been nearly
eradicated. Recently, scientists are confident they have found a way to provide an effective
treatment for diseases like Parkinson's and Alzheimer's. Additionally, they believe they have found a
way to reverse the effects of paralysis caused by serious injuries. For this essay, stem cells can be
defined as undifferentiated cells in the human body that can transform into any type of cell. There are
two types of stem cells that have been researched by scientists, adult stem cells,...show more

Adult stem cells are found in humans that have fully developed, they can be found in adults as well
as children, when adult stem cells are extracted they do not cause any real harm. Embryonic stem
cells are cells that are derived from human embryos. Extracting embryonic stem cells, however, kills
the embryo, for this reason, embryonic stem cell research has become controversial. Although
embryonic stem cell research has been a topic of controversy, it is important to examine the benefits
that stem cell research could have for medicine. Embryonic stem cells research should be accepted
by pro–life activist and religious affiliates because it can provide extensive knowledge about the
human body, provide a better alternative to current treatment, and allow scientist to understand more
about incurable diseases.
For several years, scientists have been looking into the potential benefits that embryonic stem cells
could offer. They believe that embryonic stem cells could provide an effective treatment for terminal

5). Biomedical engineers can also go to graduate school and even complete a PHD in the subject,
however a bachelors degree is enough to be qualified for a job. Biomedical engineers need to
have an understanding of biology, chemistry and physics to be able to carry out their work
properly. Biomedical engineers also need to have communication skills to be able to work with
different types of people. Biomedical engineers need various traits to be able to successfully
complete their work. The work environments for Biomedical engineers can vary. Some may work
in a lab while others can work in a hospital. Nevertheless all biomedical engineers must be able to
communicate with doctors, nurses, engineers, etc. A typical Biomedical engineers will work full
time, but they may also have to use extra time to consult with clients, and work on their projects.
Biomedical engineers must be willing to spend time on their project for the greater good, even if
it means having to work extra time. The average annual pay for a biomedical engineer in 2012
was $86,960, with the lower ten percent earing $52,600 and the top ten percent earing $139,450

Stem Cells Essay
Introduction
The use of stem cells can advance drug development, knowledge of disease, patience specific disease
treatment, and can bypass the limits of mouse–models for research. According to the National
Institute of Health (1), stem cells are unique in the following ways: they can divide and renew
themselves for long periods, they are unspecialized, and they can give rise to specialized cell types.
The uniqueness of these stem cells allows for the testing of new drugs, cell–based therapies and the
study of human development including cancer research. Human stem cell therapies have been used
for the treatment of neurological disease in human clinical trials such as Parkinson's disease (2),
spinal cord injury (3,4) stroke (5), and...show more content...
Background
The generation of stem cells from zygotes and blastomeres retain the ability to create all embryonic
and extraembryonic tissues (13) these are deemed 'totipotent', while cells that generate embryonic
and cannot generate extraembryonic tissues are deemed 'pluripotent'. Induced cells that are in a
differentiable state, pluripotent, are the cells chosen to advance medicine. Cells selected for
induced pluripotency cannot be terminally differentiated, as these cells lose their ability to be
developed into other cells types (14). Pluripotency can be induced by the study of embryonic stem
cells. These cells express factors (Oct3/4, Sox2, Klf4, c–Myc), deemed Yamanaka factors (15) and
described as such in this review. There are currently four main methods for delivering these factors
including viral vectors, DNA–based induction, RNA molecules and recombinant proteins (fig 1.)
(16,17).
Fig 1.
Induced pluripotent cells from somatic cells by transduction, DNA–based induction, RNA molecules
and recombinant proteins, creates a reprogramming wave leading to cells with the potential to
become many cell types (16). The equivalency of induced pluripotent stem cells and embryonic
stem cells is variable but using screening techniques, bioinformatics assay, cells that are more
similar to embryonic stem cells can be selected for cloning techniques (18,19). The reprogramming
wave, occurs in two parts, driven by c–Myc/Klf4 (first wave) and Oct4/Sox2/Klf4 (second wave),

Stem Cell Research : Stem Cells
Stem Cells Stem cells are cells that are found throughout the human body. They reproduce over a
long period of time without changing. Stem cells can produce specialized cells, such as brain,
muscle or lung cells. Stem cells in the last few years have recently made a big debut because
medical professionals have discovered so many unique qualities to stem cells. They are on the
cutting edge of medicine because of all their uses and the qualities that make them so unique from
any other cell in the body. Stem cells have the power to make so many breakthroughs in the
medical world. Medical researchers have all ready found so many ways that stem cells can be used
for the better of so many people. Genes play an important role in determining what genetic traits or
mutations we receive. Researching stem cells can help determine this. Stem cell research is useful for
learning many things about human development and about how the body has the power to repair
itself. Researchers are finding new ways each day that stem cells can be used and the possibilities
that they find for stem cells could be endless. A few ways they can be used to treat diseases, be
used as graphs for burn victims or surgical use, and even to correct birth defects. The pros of stem
cells are limitless.
Stem Cells have recently have caught the eye of many medical professionals because of their
unique properties, so what exactly are Stem Cells? Stem Cells are different from any other cell in
the body. They

Embryonic Stem Cells Essay
Embryonic cells should be allowed to be used because of the medical benefits they provide. They
can be used to cure diseases such as Parkinson's disease, diabetes, traumatic spinal cord injury,
Duchenne's muscular dystrophy, heart disease, and even vision and hearing loss (nih.gov 2009).
There is no problem using them for medical purposes and it is not immoral to use them for this
reason. Embryonic cells have the potential to save lives. Therefore, the usage of embryonic cells
outweighs the ethical issues.
Although many people argue that the usage of embryonic stem cells is immoral, they are thought to
have much greater developmental potential than adult stem cells (nih.gov 2009). While stem cells
are not taken from an embryo and are...show more content...
Others develop into muscle cells that can contract and also into nerve cells. Because they have the
potential to become such a wide variety of specialized cells, embryonic stem cells are described as
pluripotent. Plurip.0otency is one of two key features of embryonic stem cells. The second key
feature of embryonic stem cells is their ability to divide or self renew for an indefinite period while
retaining their undifferentiated, pluripotent state. As the cell mass grows, the population can be
further expanded by growing in larger tissue culture flasks. An unlimited number of undifferentiated,
pluripotent stem cells can be produced (Sumanas Inc. 2007).
Once there is an understanding of how embryonic cells are taken from the body, it can be
explained why they should be used contrary to the beliefs some people have. First, Embryonic
cells can cure diseases. For example, if someone is paralyzed, doctors can take an embryonic cell
and use this to cure the patient (nih.gov). A man named Rusty Leech, from Michigan, was able to
regain sensation in his body, when he previously could not because of a car accident. Two months of
physical therapy and embryonic stem cell injections enabled him to regain feeling below his waist
again. He has regained limited muscle use to help him go to the bathroom and move his legs a little
on his own. "The results were unbelievable, to feel the sensations in my body that weren't

Adult stem cell are difficult to obtain and have a lower growth potential. Although they have a
limited capacity to differentiate and they are compatible with adult tissue, you can only obtain a
small amount of cells. An alternative would be obtaining stem cell from the umbilical cord, given
the fact that are easily to obtain, they are compatible with other body tissue , they may have a
limited capacity to differentiate but they are not a treat to the child life. Both these option offer a
small amount of stem cell to work with compared to embryonic stem cells. There is a preference to
choose embryonic stem cell due to the unlimited growth potential, lower probability to mutations
and the unlimited differentiation. The only downside is that...show more content...
This means destroying a potential human life. But embryonic stem cell research could lead to the

What justifies research?
One of the things that is problematic about the debate is that it focuses so much on the status of the
embryo and the rights of the embryo and so little on the needs of the

Ethical Issues With Stem Cell Research Essay
The ethical issues of stem cell research are closely tied to their social issues. Embryonic stem cell
research causes many social dilemmas and raises the long–debated question of when life conception
starts. To many, life conception starts immediately after fertilization, supporting the idea that the
embryo is the equivalent of a human life. As a result, pro–life supporters and religious groups view
ESC research as the equivalent of murder. On the contrary, some do not believe that embryos
possess the same moral status as a living person. Supporters also argue that the blastula, where
ESCs are derived from, are already commonly created and destroyed by fertility clinics. Therefore,
instead of destroying surplus blastula, they could be put into better use in ESC labs, which could
lead to more treatments. While ESCs hold a tremendous potential for advancements in human health,
people still wonder if the benefits outweigh the costs. People have the duty of respecting human life,
however to many, ESC research violates this principle, since it results in the destruction of a human
embryo. Meanwhile, people also feel the moral responsibility of helping...show more content...
It results in a one–celled embryo that is genetically identical to the donated somatic cell. Cloning
embryos is a technique aimed at providing a source of stem cells that can be used for research and

raises the question: What is the moral status of an embryo?
The answer is subjective, and SCNT faces many opponents from religious and pro–life organizations,
since it involves the creation of an embryo with the purpose of destroying it. On the other hand,
supporters believe that the treatments that could potentially be developed outweigh its

Raise of hands. How many know someone who has or had heart disease? Keep your hands up.
How many know someone who has or had diabetes? How many know someone who has or had
cancer? Okay, you can put your hands down. Right now, in the United States alone, thirty million
people have heart disease ("Heart Disease"), twenty–five million people have diabetes
(Santos–Longhurst), and fifteen million people have cancer. (Cancer Statistics"). That equals
seventy million moms, dads, or children that are suffering from these chronic diseases, but can be
treated with the use of embryonic stem cells. Embryonic stem cells are cells derived from the
undifferentiated inner mass cells of human embryo. In simpler terms, these cells have the ability to
develop into any of the two hundred different cell types in our bodies. Unlike most of the cells in
our bodies, such as heart cells or skin cells, which conduct a specific function, a stem cell does not
have a specific function until it is specialized (Hogan). A stem cell that is becoming specialized
will go through steps, which are simulated by scientists in the laboratory. When scientists
manipulate these cells, they first must extract the inner cell mass of an embryo and place the cells
in a cell culture, which you can visualize better looking at this diagram ("Basic Stem Cell Facts").
After the cells are placed in the culture, which is just an artificial environment for the cells to grow,
the scientists will mimic similar signals in order for

regulations of stem cells. Given the number of countries that are currently experimenting with
stem cells, this essay will only discuss the regulations imposed by the Food and Drug
Administration (FDA) and the National Health Institute (NIH), both agencies of the United
States Department of Health and Human Services. The scope of this paper does not include
ethical, religious and/or moral issues. This paper is addressing stem cells research because this
topic gives us, civilians, something called hope. We cannot count the number of doctors
/researchers who struggle on a daily basis to find hope for victims of a multitude of diseases and
disorders. In the United States alone, 16 million people, including hundreds of thousands of
children, suffer from diabetes. There are more than 4.5 million people with Parkinson's disease,
more than 5.5 million with Alzheimer's disease, and nearly 5 million with congestive heart failure
(Kelly, 2007). Being able to treat some of the worst experiences a human can possibly experience
in his/her life, provides us with hope for a better future. Moreover, this could also open the doors to

So basically I'm gonna summarize an article and it's about the genetic profiling of putative breast
cancer stem cells from pleural effusions. The authors of this article used this opportunity and found
out that pleural effusions were great opportunities to be able to study metastasis and for isolating
stem cells. The doctors basically isolated the cancer stem cells(csc) and the non cancer stem
cells(non–csc) and were able to derive how fast these stem cells were able to form. At the moment
breast cancer is the leading cause cancer related deaths in females. This mortality rate seems to stay
around the same due to something called cancer metastasis(the growth of another cancerous tumor
away from the primary tumor. And for this reason they...show more content...
So scientists basically separate all the cells from a clump and let them float in some liquid. After
a while the fast developing cancer cells will begin to duplicate at a fast rate while normal cells
would do that at a slower rate. Scientists later then sorted out the CSCs (cancer stem cells) and
tested them for ALDH1. But most of these tests came back with some negative results as they had
been detected in some pleural cells but only had a median detection of 2.7%. So they then used a
CD44+CD24 detection sample and they were able to evaluate 13 out of 18 pleural effusions (72%).
(Defining CD24– a heat stable antigen found on the surface of a cell CD44– hyaluronic acid
receptor) These tests were done until sample 13 because after sample 13 they added optimization
steps which included having the samples filtered through a wide mash and then filtered through
another filtration strainer after the lysis step. These received better results with the unsorted cells
instead of the sorted cells which made mammospheres.

that purpose including one of the most fascinating and highly active areas at present, stem cells

hope in modern treatment.
The first successful case of stem cell therapy in human was reported in 1959. Bone marrow

However, this problem could be minimized in nonmalignant patients by using autologous
transplantation.
Cell contamination is another risk factor in stem cell therapies that should be concerned. Since stem
cells are human–derived products, contamination could occur at any steps in process. Start from
stem cell sources or donors, they might carry viruses, parasites or diseases that can infect patients
after transplantation. So, donor screening tests and assessment need to be performed (Sacchi et al,
2008). Medical and familial histories of donors are also essential and should be scrutinized in order
to avoid getting stem cells from someone that might transmit congenital defect, autoimmunity or
malignant disease to the patient (Niederwieser et al, 2004). Harvesting and culturing of stem cells
are the processes that might have caused the microbial contamination as well, thus, sterile technique
must be cautiously conducted during those steps.
Up till now, bone marrow or hematopoietic stem cells transplantation has been proofed to cure many
diseases such as aplastic anemia, acute and chronic leukemia, and severe thalassemia with low

There are several types of stem cells. One type is the adult stem cell. "Adult stem cells are
tissue–specific, meaning they are found in a given tissue in our bodies and generate the mature cell
types within that particular tissue or organ" (Gage). They are bone marrow or cord blood stem cell
transplants that are used to treat diseases of the blood or to repair the blood system after
treatment for certain cancers. An additional type of adult stem cell is the mesenchymal stem cell.
"These are found in a number of tissues, including bone marrow, and may be able to produce
bone, cartilage and fat. It is also possible that these or similar cells may aid in the regeneration of
tissues" (Gage). An alternative stem cell is the embryotic stem cell. Fred Gage states,
"Embryonic stem cells are derived from very early embryos and can in theory give rise to all cell
types in the body" (par. 4). Unfortunately embryonic stem cells have the capability of transforming
into cancerous tissue after being transplanted. Alice Parks, the medicine reporter for Times
Magazine, states, "Embryonic stem cells are known for their ability to grow indefinitely" (par.6). In
order to be used in cell transplant treatments, the cells will most likely need to be engaged into a
more developed cell type. This will diminish the chances for the cancer to mature.

Stem Cells and the Future
What exactly are stem cells? How can the use of these cells benefit us and how exactly
are they acquired? Believe it or not stem cells have been in play when it comes to medicine since
the 1950's in France (Steenblock 1). This topic is very controversial and I surmise that it is
strongly due to the lack of knowledge when it comes to stem cells and their importance. I,
myself, am very intrigued by stem cells and my goal is to define what they are and layout facts
pertaining to them.
This paper will be divided up into three main sections: what are stem cells and the
different kinds; why stem cells are important and how they are medically beneficial; how stem
cells are acquired and used for treatment. The last section will be followed up by the conclusion.
There is a lot of information pertaining to this, therefore each section will begin very broad and
finish very concise, much like a funnel.
So, what are stem cells? According to Kirkpatrick, stem cells are an essential part of the
broader field of regenerative medicine and are pertinent in preventing and treating diseases that

essential because of the beneficial aspects it has to offer. Stem cells could potentially treat
conditions such as Alzheimer 's, Parkinson 's, birth defects, strokes, Diabetes, cancer, and help in the
reconstruction of severely damaged organs. Although stem cell research withholds great potential
for many medical advances, a lot of controversy surrounds the sources and methods of obtaining
stem cells and the possibility of improper usage of the knowledge acquired from research and
experimentation. It is necessary for scientist to continue research as well as recognizing any ethical
issues that may be present.
There are two different types of stem cells; unlimited and limited. Unlimited stem cells come
from embryos and are referred to as embryonic stem cells (ES Cells), these cells are more
medically valuable than limited stem cells. They are referred to as unlimited stem cells because
they have the ability to develop into any type of cell of tissue in the human body. Limited stem
cells come from adult bone marrow or umbilical cord blood cells. Limited stem cells are more rare
because they are harder to obtain and can only be found in some developed
