Pros And Cons Of Embryonic Stem Cells

316 Words2 Pages
Embryonic stem cells come with numerous pros and cons. Embryonic stem cells (ESCs) are stem cells derived from the undifferentiated inner mass cells of a human embryo. Embryonic stem cells are pluripotent, meaning they are able to grow into all derivatives of the three primary germ layers: ectoderm, endoderm and mesoderm. These cells can be grown easily in culture. Stem cells differ from other kinds of cells in the body. All stem cells, regardless of their source, have three general properties. They are capable of dividing and renewing themselves for long periods, they are unspecialized and they can give rise to specialized cell types. Additionally, under defined conditions, embryonic stem cells are capable of spreading themselves indefinitely.

This is because embryonic stem cells are a type of unspecialized cell, so they can form into any type of cell. As Junying Yu and James A. Thomson say in their article about Embryonic Stem Cells, “human [embryonic stem cells] promise an essentially unlimited supply of specific cell types. . . for transplantation therapies for diseases” (Thomson). This explains that this course of treatment would allow not only the treatment of, but possibly even a cure for, diseases that are caused by either malfunctioning cells or the loss of them.

This root tip was choosen because of its rapid growth and it can be easily avaliable and grown in large numbers. The rapid root growth proved advantageous as it allowed the observation of multiple cells in each mitotic stage within a small sample. It was expected that the majority of the cells found would be in interphase as a large proportion of the cell division cycle is spent with the cell performing its normal cellular functions. Materials: The Materials required for this experiment include; a

Over the years, there have been many controversial issues surrounding medical research, but one of the most arguable topics of all time is the use of embryonic stem cells. Some individuals believe that extracting stem cells from unborn babies will be useful to create new medications or, in most cases, help regenerate damaged cells. Although, many people disagree with the process scientists use to obtain these stem cells. By continuing embryonic stem cell research, scientists are denying an unborn child the chance to live, they are not letting nature take its intended course, and they are not adhering to the religious or moral beliefs of many people.

In recent years, several competing viewpoints have emerged about embryonic stem cell research. All of this debate raises an important question, Should embryonic stem cell research be conducted for treatment of present and future diseases? People who believe that an embryo should not be destroyed tend to say that embryonic stem cell research should not be conducted. On the other hand, people who believe that embryonic stem cell research creates means of curing diseases reply that the research should be conducted. Embryonic stem cell research “uses special cells found in three-to-five day old human embryos to seek cures for a host of chronic disease” (PRC).

Embryonic stem cells are cells that can be taken from embryos that have been fertilized through in vitro fertilization. (They are not taken from the fertilized eggs in a woman’s body.) Other methods of getting the embryonic stem cells would be through getting it from the umbilical cord or from the placenta once the baby is born. Stem cells have the ability to be used to increase the health of the new born baby in future in the event of an accident

Stem cell research has become one of the most controversial current topics of biology. This controversy comes from the idea that these stem cells are only embryonic stem cells, and the only way we get them is from the destruction of human embryos. By definition, a stem cells is an undifferentiated cell of a multicellular organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cell arise by differentiation. Which simply means they are cells found in the human body that can create any other kind of human cell, so under further observation, stem cells could cure many diseases. Despite prior ideas, there are actually two types of stem cells, embryotic and somatic (adult) stem cells.

STEM CELL RESEARCH is a very controversial topic in today’s time. Not only has it sparked a hundreds of debates it also has been the center of much criticism for its use of human cells. For those of you who don’t know stem cells are unspecialized cells found in living things and are able to grow and rebuild themselves as long as the host is alive. Stem cell research is not worth supporting. Advocates of stem cell research believe that the cells are not equivalent to human life because it is inside the womb even facing the fact that the start of a human life is in the moment of conception.

When one hears the word Eugenics, one associates it with the terrible actions of Nazi Germany, but Germany was not the only country, which adopted the horrible social movement known as Eugenics. It took place in countries such as Great Britain, Sweden, Australia, USA and many more, all of whom introduced policies and programs such as birth control, marriage restrictions, segregation, forced abortions and sterilization, and worst of all genocide with aims to improve the human race by potentially breeding out undesired traits and ridding society of all those deemed as “unfit”. The idea of breeding out undesirable genes or traits is loaded with problematic value judgments, and the various ways that such ideas have been implemented as policy have scared many people and lead to the deaths of millions of people, therefore it undoubtedly has a bad reputation.

Eugenics is the science of using artificial selection to improve genetic features of the population. It is thought that improvement of the human race can be seen through sterilization of people who exhibit undesirable traits and selective breeding. Often called Social Darwinism, the concept was widely accepted during the time of World War I. It quickly became a taboo after World War II when Nazi Germany used it as an excuse for genocide. The thought of improving the human race by manipulating who is allowed to breed can either be appalling or compelling.

There have been many different experiments to try and grow different objects. A Dutch scientist is growing pork in a lab by growing pig stem cells and cultivating them until they become pig skeletal muscles. Their previous attempts to perfect the texture of the meat fell short and more work needs to be done before it goes into the public, But they believe that in the near future this will be a new science breakthrew. Many also believe that this could one day help end world hunger and reduce the slaughtering of animals. Stem cells have a remarkable feature, they can become bone, muscle, cartilage and other specialized types of cells.

This process provides a safe alternative to embryonic cells, as the stem cells did not produce tumors. Adult stem cells are also being found in more tissues than ever thought (Stem cell Basics). This would allow many different uses of the adult stem cells, as they can only form certain major cell types of a tissue or

Artificial tissues such as skin are formed using stem cells in the laboratory. As a case in point, in 1990, Gary Stakemiller, an electrician in Orlando received a skin transplant made of skin that was grown in a laboratory (Ricks). Stakemiller needed this graft because over a month earlier, he received burns on seventy five percent of his body (Ricks). The new skin was produced by using a “starter” medium which grows in a laboratory from cells into usable skin (Ricks). It takes about three weeks to grow each sheet of skin from cells, proteins, and nutrients (Ricks).

Is Genetic engineering Safe? Genetic engineering is the modification of an organism’s genetic composition by artificial means, often involving the transfer of specific traits, or genes, from one organism into a plant or animal of an entirely different species. Human beings ought to consider the pros and cons of genetic engineering before using it. It is a contentious topic because people have different views of weather genetic engineering is safe or not.
