Adult Stem Cells Vs. Embryonic Stem Cell Research

These cells come from fetuses which is why stem cells are such a controversial issue. In order to actually use embryonic cells, they must be harvested from an unborn baby that is in the early stages of life. Embryonic cells have the ability to be all 220 types of tissues in the human body. “This makes them ideal for regenerating diseased heart tissue, repairing spinal cords, and replenishing brain cells”, Elizabeth Svoboda, an author in the publicized Popular Science magazine, illustrates in her article about stem cells (60). Embryonic cells have limitless possibilities in medical advancement. These cells can become whatever type of cell a doctor program them to be. With the use of embryonic stem cells, doctors can cure several diseases, as well as curing people who have suffered injuries, but research is being slowed down by the ethical dilemma of aborting a

It has the ability to form any type of specific cell and thus has the greatest potential for treatments in the near future.  A more recent development in stem cell research is the creation of induced pluripotent cells, which are adult cells that become undifferentiated through a series of treatments.  Induced pluripotent stem cells have a number of benefits because the destruction of embryos is not necessary and there are no issues with immune response or rejection because the cells come from the patient.  However, it will be a long time before this type of cell become widely used on humans because the method used is not completely understood and has negative side effects.  In animal testing, “…the virus used to introduce the stem cell factors sometimes causes cancers” (“Stem cell basics”).  Therefore, embryonic stem cells should be an important part of stem cell research.  Even if induced pluripotent cells can replace embryonic cells in the future, the knowledge gained from current embryonic cell research would still be very applicable.   Unfortunately, research is very time and resource intensive, which is where the debate of federal funding comes into play.

The embryonic stem cells can be used for various medical cure. It can help treat diseases including Parkinson's, stroke, heart disease and diabetes. The embryonic stem cells are cells that can easily be transformed into any cell. This can help treat many diseases but this may also increase the number of women selling their eggs and undergo dangerous procedure to do. We don’t agree with the use of the embryonic stem cells for research.

Why is the mainstream media significantly downplaying exciting scientific discoveries with adult stem cells? This essay hopes to adequately answer that question.

All the human embryonic stem cell lines currently in use come from four to five-day-old embryos left over from in-vitro fertilization (IVF) procedures. In IVF, researchers mix a man 's sperm and a woman 's eggs together in a lab dish. Some of those eggs will become fertilized. At about five days the egg has divided to become a hollow ball of roughly 100 cells called a blastocyst which is smaller than the size of the dot over an “i”.

When the topic of stem cell research, and/ or treatment, people generally automatically jump to the conclusion of embryonic stem cells, when in retrospect according to Eurostemcell.org, an organization based website that is dedicated to supplying the public with the latest news and information on stem cells. According to the article there a few different types of stem cells. The first type of stem cell is, embryonic. Embryonic stem cells are grown in a laboratory from embryos cells at an early stage. The second type of stem cell is tissue stem cells. Tissue stem cells are found in all different parts of the body. Lastly the third type of stem cell is, Induced pluripotent stem cell (iPS), or 'reprogrammed' stem cells. IPSC are similar to embryonic stem cells but they are from adult specialized cells.

There have been an argument about whether embryonic stem cell research should be used or not. Embryonic stem cells are derived from the inner mass of a human embryo. They are pluripotent which means they can grow into most cells. They can also become all cell types of the body. Embryonic stem cells have the capability of spreading themselves indefinitely in an undifferentiated state.

Therefore, much of the critic’s arguments are invalid due to the fact that the embryo won’t develop into a child. Stem cells are the beginning of an enormous scientific breakthrough, a breakthrough that critics are simply putting off. Embryonic stem cells have the potential to treat some of the worst diseases we face today, such as cancer. Many critics argue that adult stem cells offer a good alternative. However, adult stem cells have become specialized and only have the ability to become specific type of tissue. Unlike adult stem cells, embryonic stem cells have the ability to create any type of cell within the body, as well as replicate themselves. This difference is proof alone that embryonic stem cells are vital to treating the more complex illnesses. Due to this, embryonic stem cells would create a larger bank of replacement cells and tissues. This is important because although there is organ and tissue donation, there is a higher demand for them than we have to supply. With embryonic stem cells, there would be more available treatment for patients with diseases such as macular degeneration, spinal cord injuries, heart disease, and more. In the case of heart disease, with the use of embryonic stem cells, healthy heart tissue could be generated in the lab and then transplanted. This would lead to a quicker treatment option than waiting for an available tissue and organ through

Adult stem cells, like embryonic stem cells, have the ability to differentiate into several more specialized cell types, but the potential number of cell types is far smaller than that of an embryonic stem cell. Embryonic stem cells, by nature, eventually turn into every type of cell in the body, whereas adult stem cells will only turn into a few cell types. For example, a blood stem cell, one type of adult stem cell, will eventually turn into one of eight types of specialized blood cells (Jordan 116.3).

Embryonic stem cells are stem cells that have been taken from the inner cell mass of a blastocyst. The blastocyst is formed approximately four days after conception. The blastocyst has an outer layer of cells that will form the placenta and other supporting tissues needed for fetal development in the uterus. (Swomley, 2002) In fetal development the blastocyst is what develops into an embryo but embryonic stem cell research removes the inner cells of the blastocyst essentially killing the embryo and prohibiting it from developing into a healthy fetus. These embryonic victims come from two main sources: surplus embryos donated by fertility clinics, and discarded fetuses from abortion clinics. (Vallance, 2005) While many claim this type of research is critical for the advancement of medicine it is an unnecessary method to advance

In addition to research, these types of stem cells are used to restore and repair damaged tissue in all kinds of diseases. Embryonic stem cells are so useful because they have pluripotency, which means that they can differentiate into any human cell type. The cell types that they are commonly induced in are brain, heart, liver and insulin pumping beta cells that are similar to the pancreas. Since these embryonic stem cells can be differentiated into so many types of cells, they are able to treat diseases like: Alzheimer's, Parkinson's, diabetes and many more.

Embryonic Stem Cell Research are pluripotent stem cells derived from the inner cell mass of a blastocyst. I believe that the use of Embryonic Stem Research is beneficial to society because these cells have unlimited potential. They can allow permanent repair to failing organs by injecting healthy cells into the damaged organ. They also can used for finding and preventing cures for cancers, Parkinson’s disease, birth defects, spinal cord injuries, and strokes. However, Stem Cell Research is a controversial topic, especially when referring to Embryonic Stem Cell Research.

Amniotic stem cells are found in the amniotic fluid around a child just before it is born (Mayo Clinic Staff). Amniotic stem cells are primarily used for organ regenerations because there is a very rare chance that they will cause an immune system attack. Embryonic stem cells make up an entire embryo as it is developing. Embryonic stem cells, also known as blastocysts, start forming into vital organs, such as the heart and lungs, before the embryo is even a week old ("Stem Cell Information"). Adult stem cells, called somatic stem cells, are found in anyone who is no longer a fetus. They could be found in children and fully grown adults. Adult stem cells, however, are limited to what they can produce. They can only maintain and repair the tissue they are For example, the stem cells in adults can only be found in bone marrow, blood cells and fat cells (Mayo Clinic Staff). Adult stem cells still have the potential to be useful for society. Researchers are trying to alter the genes inside of an adult stem cell to make it more adaptable like an embryonic cell ("Stem cells: What they are and what they do"). These stem cells are called induced pluripotent cells and they cannot be used for curing any diseases because when you change the genetic makeup of something, you cannot always get the predicted outcome, so further research must be

Stem cells can become many different cell types. There are three main types; totipotent, pluripotent, and multipotent. They have already have been successful in treating some diseases and have the potential to cure many other diseases. Stem cells have also been very useful in drug testing. However they have caused a lot of controversy, but some technology has helped settle this controversy.

Human embryonic stem cells (ESCs) are pluripotent cells isolated from blastocysts, and are highly useful in studying human development (Itzkovitz-Eldor et al., 2000 p. 88). Although the National Institute of Health states that “it is not known if iPSCs and embryonic stem cells differ in clinically significant ways”, iPSCs are already being used to achieve the same results as ESCs in some applications without the use of embryos, removing the ethical concern associated with ESCs (National Institutes of Health, 2009). ESCs are capable of differentiating into all cell types, and can be used as a source of differentiated cells. In the report by Itskovitz-Eldor et al., they discuss the induced differentiation of ESCs in suspension into embryoid bodies, including the three embryonic germ layers. The authors state that “the ability to induce formation of human embryoid bodies that contain cells of neuronal, hematopoietic and cardiac origins will be useful in studying early human embryonic development” (Itzkovitz-Eldor et al., 2000 p. 88).
