Stem Cell Research : Stem Cells

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 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.

With the hopes of curing the patient’s afflictions, these newly grown cells would then be transplanted into the patient. With this approach come major problems such as the formation of tumours, which is caused by the distinguishing trait of stem cells. Because stem cells are able to divide for an unlimited amount of time, it has been found that the cells will not know when to stop dividing and they will continue to divide even after being transplanted into the patient (Herold 48). This form of treatment is counterproductive, as uncontrollable cell division will produce tumours and potentially cause cancer, which is one of the ailments that stem cell research promises to cure.

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

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 are cells with the potential to become any type of cell in the body. There are two different types of stem cells: adult stem cells and embryonic stem cells. Adult stem cells are very valuable and are used mainly to treat blood diseases, but sometimes adult stem cells from the brain are used to treat neurological diseases. Adult stem cells can also be difficult to recognize in the adult body. Embryonic stem cells are more flexible than adult stem cells and can be used for a bigger variety of diseases (California’s Stem Cell Agency,2011). Some people do not believe in the use of embryonic stem cells, because they believe they are killing future life. Despite the controversy over how stem cells are gathered, stem cells have undeniable

Stem cells were first discovered during an experiment with mice in 1981 ("Stem Cell Information"). Scientists extracted stem cells from embryonic mice, which led to the discovery of vitro-fertilization in 1998. Virto fertilization is used to conceive a child in a laboratory, for parents who cannot conceive naturally. The fertilized egg is then implanted inside a mother's uterus and a child begins to form. Without the discovery of stem cells, this process might not have been able to give parents the children they have always wanted ("Stem cells: What they are and what they do"). However, this is causing some controversy in today's society. Embryonic stem cells are obtained from embryos not placed inside a female. Researchers felt it could harm or even kill the undeveloped child, so they felt the only solution was to grow the fertilized eggs in laboratories. The embryos are grown in labs with consent from their donors. The stem cell obtained from these embryos are being used to benefit burn victims so they could grow healthy skin, people with spinal cord injuries so they could have the chance to walk again and even people with type I diabetes to help produce their own insulin. If these cells are able to be manipulated enough, there might even be a cure for cancer or any other heart breaking diseases wrecking havoc today (Mayo Clinic Staff). Stem cells are also

The stem cells that originate in the inner mass found in embryos a few days old are grown in the laboratory and are referred to as embryonic stem cells. A branch of these cells are embryonic germ cells, and these are derived from egg and sperm cells in a five to ten week old fetus. Both of these types of stem cells are pluripotent. In embryonic stem cells, the blastocyst cells divide and eventually develop into all of the tissues and organs of human beings. Embryonic stem cells are capable of being grown in the laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, and other cells. (Morgani, et al.

Stem cell research and engineering is a widely disputed topic that often divides people in science, ethics, and religion. In order to fully understand the controversy surrounding this area of scientific research and discovery, one must be informed as to what stem cells are. In the article, “Human Embryonic Stem Cells: Research, Ethics and Policy”, stem cells are described as “primitive cells with the capacity to divide and give rise to more identical stem cells or to specialize and from specific cells of somatic tissues” (Wert 672). Essentially, stem cells can potentially provide an unlimited supply of cells that could form some or all body cells. This ability to transform into different types or all types of cells depends of the type of stem cell, which can be divided into embryonic stem cells and adult stem cells (Bishop 1). Embryonic stem cells are extracted from preimplantation embryos and are pluripotent, meaning they possess the ability to form cells of all tissues in the adult human body. Adult stem cells, however, are limited to what tissues they can transform into.

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 diseases and provide knowledge about the human body during its developmental stages. It is important

Stem cells are undifferentiated cells that have the ability to become many different cell types by the process of mitosis and differentiation. Due to this unique property, many scientists are keen to researching and working with these cells. Furthermore, Stem cell is one of the most potential gates to curing diseases and developing new technologies.

Scientists are interested in stem cells for their ability to become any type of cell in the body, a process called differentiation. Theoretically, this allows for limitless possibilities in disease

What if there was already a way to cure cancer out there right now? What if it was right at the tip of humanity’s fingers, and with a little bit more reach it would be ours? This miracle is known as Stem Cell Research (SCR). Stem Cell Research is a relatively new field that has shown much promise to help deal with hundreds of different conditions and diseases. Though this astounding field holds the key to saving thousands of lives, there is a misguided ethical problem with Stem Cell Research raised by the church. The church only focuses on one aspect of harvesting stem cells when there is more than one way to get stem cells. This isn’t the only thing that is holding SCR back. Stem Cell Research has a chance to be something great but it needs; a better public image (at least from the religious community,) better funding so that progress can be made to put the stem cells to human testing, and more focus on a huge project that has been put on the backburner for so long.

What are stem cells? Stem cells are undifferentiated cells that are found in multicellular organisms. The reason for scientist’s interest in stem cells is because of the possible applications of using them. These stem cells can be used to regrow organs/tissues. By using stem cells, scientists may be able to find cures for different cancers, certain genetic diseases, and different physical trauma damages. They can be used to treat a variety of different medical problems but the issue with stem cell research is that embryos are destroyed when the stem cells are harvested from them. This is considered the moral dilemma that has prevented research in the past. There are three different types of stem cells: embryonic, induced pluripotent and adult.

. Stem cell is a cell that has the ability to change into several or multiple types of cells or into any cell type in the body. There are two main types of stem cells, adult stem cells and embryonic stem cells. Embryonic stem cells are found in cells that have only undergone the first few dozen cycles of growth and division following the fusion of egg and sperm. These cells are pluripotent and can be maintained so that they grow and divide indefinitely without differentiating. Likewise, they can differentiate into all the cell types in the body. They can be derived from somatic cell nuclear transfer (SCNT), sometimes also known as therapeutic cloning.
