Fluidity Of Stem Cell Research Essay

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

Many of us have all heard the saying that a “lizard can lose its tail,” and bizarrely enough it will grow back. This was always considered impossible for humans, an idea belonging in the realm of science fiction, but now the regeneration of tissue is an extremely realistic possibility. Despite some opinions, this process does not happen naturally, or take place as cinematically as one might imagine. Over the past decade, there have been major advances in regenerative medicine, commonly known as stem cell research. Stem cells are undifferentiated cells within the body that have the capability to specialize into any tissue. They are most commonly found in cord blood, bone marrow, organ donations, placenta, and embryos . Stem cells are seen by some as a new miracle treatment, encouraging many countries to invest in their research.

Stem cell research has been quite a controversial topic since its origin in the 1960s by Gopal Das and Joseph Altman. Of course, anything that uses a human embryo would be. Stem cell research could open a vast number of new doors for modern science, it could let us test new drugs, one of which could be the unfound cure for AIDS or Alzheimer’s disease. However, this branch of science comes at a high price, the price of a human life that is only five to six days

Stem cell derivatives may be a beneficial source of transplantable cells that may be able to repair and regenerate certain tissues. If this could be accomplished, the medical benefits would be enormous, such as helping Parkinson disease, MS, diabetes, and muscular dystrophies. Although, this could be an extremely important advancement in the field of medicine, there exist many ethical and religious issues that look down upon destroying embryos for research. The stem cells that are focused on in this report are embryonic stem cells. However, adult stem cells may also be used to give rise to lineages of cells that are more specialized than themselves. They are more differentiated than embryonic stem cells. Research using adult stem cells is much less controversial since they can be obtained without destroying an embryo. There is also a strong political aspect that has been brought up in recent discussions regarding groups who try to push adult stem cell research over embryonic stem cell research since they consider it a more permissible option. In contrast, people in favor of embryonic stem cell research try to discredit the potential of adult stem cell studies.

is a stem cell? Well basically they are cells in the human body that exist in a sort of neutral

A stem cell is defined as a cell that can change into a different type of cell. Stem cells are different from other cells because from the start they do not have specialized functions. Embryonic stem cells are found within the blastocyst (embryo), which is just a tiny package of

Stem cells are a type of cell that basically always divide in order to replace other cells in the body. They are different from normal cells because once they have first divided into a new stem cell, they can become another type of cell, such as a muscle cell or blood cell, tissue, or they can continue being a stem cell. They also can remain inactive for a period of time, yet they can still divide into new cells whenever they are needed.

this research would be to identify the factors that are involved in the cell making process that determines cell specialization. A few of our extreme medical conditions, like birth defects and cancer, are a direct result of abnormal cell specialization. If researchers obtain a better understanding of the normal cellular process, they can isolate the causes of these deadly illnesses. The most exciting potential use for stem cells is the generation of tissues and cells. Many diseases are a direct result from complications of cellular functions or destruction of tissues in the body. Many people donate organs and tissues to replace failing or destroyed tissues. Unfortunately, there are many more people suffering from these disorders than there are organs to transplant. That is where stem cells step in. They will give humans a chance to have a renewable source of cells and tissues that will treat a slue of diseases, and disabilities such as, Parkinson’s, stroke, burns, Alzheimer’s, spinal cord injury, diabetes, rheumatoid arthritis, and

First of all an understanding of what a stem cell is, where it comes from, and the significance of it's medical potential is essential. Stem cells are the "master cells" that form the human body or whatever other animal it is from. Stem cells can be extracted from adult tissues, bone marrow, umbilical cord blood ( ), and embryos in the blastocyst stage. Although scientists have found ways to manipulate the stem cells from adult sources into other types of cells, they claim that they are less capable of deriving the desired tissue and are not "biologically equivalent" ( ) to stem cells extracted from embryos.

Stem cell research is the future of medical and biological research and remedies, and it is fascinating to watch the progression of this new and important science as it unfolds. These cells were discovered in mouse embryos in the 1980s, and are remarkable because of their potential to grow into a variety of different kinds of cells within a body. Common in fetuses, and more rare in adult animals of all kinds, stem cells can be manipulated in useful ways to repair many tissues, dividing limitlessly for therapeutic purposes. When a stem cell divides, each new cell has the potential either to remain a stem cell or to differentiate into more specialized tissue, such as nerve, pancreas, bone marrow, or unique blood components. Initially

Stem cells are cells which can essentially form into any type of cell that can be found in the body. There are various types of stem cells. These include embryonic, adult, genetically reprogrammed adult stem cells, and perinatal stem cells. The most versatile, as well as controversial, type of stem cells are embryonic stem cells. These cells are found in 3-5 day old embryos which are formed through in vitro fertilization ("Stem Cell Basics" 1). While scientists have been able to reprogram adult stem cells to act as if they were embryonic, there is yet to be any conclusive evidence as to how the use of the altered cells will affect humans ("Stem cells: What they are and what they do" 1). The use of stem cells is largely focused on regenerative medicine which takes advantage of the stem cells versatility to create and replace damaged tissues in

One of the most controversial topics these days is Stem Cell Research. There seems to be a split opinion among societies about the research and whether it is socially and morally acceptable. As a society, we need to open our minds to the possibility of broadening our scientific horizons with stem cell research, and take the time to learn and understand whatever we can about it.

Stem cell research has shown enormously promising results, and deserves to be pursued by scientists worldwide. In the short time stem cell research has been around, amazing things have happened, and continue to happen. For example according to the article “9. Can Stem Cells Repair a Damaged Heart?” Research on mice has showed promising result with the injection of bone marrow cells into damaged ventricle walls. In their studies, scientists were able to take a group of bone marrow cells with a high capacity to develop into other cell types, and get them to form new cardiomyocytes, vascular endothelial, and smooth muscle cells. Cardiomyocytes are the heart muscle cells that contracts to eject the blood out of the heart's ventricles, and vascular endothelial are the cells that line all vesicles (both veins and arteries). Smooth muscle cells are the cells in smooth muscles, such as the ventricles in the heart. The creation of new cardiomyocytes, vascular endothelial, and smooth muscle cells lead to the generating of newly formed heart muscle, including coronary arteries, arterioles, and capillaries (Can 2015). If this technology can be translated from mice to humans, this could revolutionize the way we see modern medicine today. There could be an end to people dying waiting for heart transplants, and catastrophes resulting from heart attacks. The ramifications are endless. Additional advancements have been made in the area of the pancreas. As stated in the article “7. Stem Cells and Diabetes”, “ promising studies indicate that insulin-producing cells can be cultivated from embryonic stem cell lines” (Diabetes 2015). This could mean new treatments, and possibly cures, for diabetes. Despite the fact that embryonic stem cell, which is the most promising type of stem cell research, results in the destruction of an embryo it provides the opportunity for hundreds

Stem cell therapy advocates the reparative response of diseased, dysfunctional or injured tissue using stem cells. Regenerative medicine holds the promise of ways to repair cardiovascular damage and improved cancer treatment. Stem cells are used to treat leukemia, some joint repairs and repair the liver. The adult stem cells used to treat autism comes from the human umbilical cord tissue. The role of stem cell therapies has brought the success level of scientists higher as they are soon to discover treatments for more diseases.

Stem cells have the potential to develop into various cell types in the body. Stem cell research has been an ongoing process for many years. The past 10 years has seen
