Stem Cell Research : The Era Of Life Science Essay

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.

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).

Pluripotent stem cells are just like Totipotent cells, but they can only become cell derived from the three germ layers, which contain over 200 specialized cells. Multipotent stem cells can only become blood cells, such as red blood cells, white blood cells, or platelets. Unipotent stem cells can only transform into one type of tissue or specialized cell, but it can divide over and over again (Wikipedia). These embryonic stem cells can divide again and again through mitosis (a type of cell division in all body parts except reproductive parts). Medical specialists and leading scientists conclude, that these cells could help cure as many as seventy-three diseases, which up to now were thought incurable (NIH).

In the past two decades, many technological and scientific advances have been made in order to make life easier for many people who suffer from cancer, disease and sickness. Among these advances there is something revolutionary called stem cells. Stem cells can help restore and regenerate almost all parts of the human body such as the heart, kidney, liver, and many other organs. Although stem cells offer a lot, there are many views against and for stem cells, and among these views lies the debate of whether stem cells should be legalized or not (NIH 2). Stem cells offer exciting new opportunities in the field of science such as regenerating human body parts, but many people are still debating whether or not the use of stem cells is

One of the most heated political battles in the United States in recent years has been over the morality of embryonic stem cell research. The embryonic stem cell debate has polarized the country into those who argue that such research holds promises of ending a great deal of human suffering and others who condemn such research as involving the abortion of a potential human life. If any answer to the ethical debate surrounding this particular aspect of stem cell research exists, it is a hazy one at best. The question facing many scientists and policymakers involved in embryonic stem cell research is, which is more valuable – the life of a human suffering from a potentially fatal illness or injury, or the life of human at one week of

These cells can grow into many things such as organs, tissues, muscles, or blood. These cells are able to renew themselves through cell division. One of the most unique aspects to these cells are they are able to replenish and repair themselves as long as the person is alive. This can be seen most commonly in red cells of the bone marrow. These cells are continuously repairing and replacing damaged and old cells. Because of stem cells unique ability to renew themselves into new cells, scientist have shown great interest in these cells. Stem cells that are being studied most by scientist are embryotic stem cells, adult stem cells, and induced pluripotent stem

In Brazil 2009, there was an 18 year old boy that had half of his jaw and teeth removed because of a tumor. Scientists took some of his bone marrow and extracted the adult stem cells from it and formed an osteoblast, which is a bone forming cell. Six months after the osteoblast was injected, it started forming new bone material which filled the gaps (NIH Stem Cells). Stem cells could be a genius way to treat many diseases and disorders and it should be supported by everyone.

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

When a patient is faced with a terminal illness or is told that they will never walk again, it may be difficult to find hope of any kind. Stem Cells provide a faint glimmer of hope, with all the amazing things they, in theory, are able to do and cure. What kind of stem cells are we talking about though? Embryonic, Adult, or Cord Blood? All these possess the ability to replicate themselves as well as become any type of cell (Harvard Gazette). As with any incredible feat there is more often than not a “catch.” Many questions arise when we think about the sacrifices, risks and benefits. It is a matter of where we owe our obligations, to the embryo or to the thousands of people who are suffering and dying with incurable diseases. A diverse

Abortion, gay marriage, and illegal immigration are all hot button topics currently being faced by Americans. As ardently as each side defends their stance on a controversial issue, an opposing side fights with equal diligence for the beliefs they feel should be valued by our nation. Perhaps nowhere is this battle more heated than in the fight over stem cell research. While supporters of this new field of science tout it’s potential to cure everything from blindness to paralysis, those against stem cell science liken the procedures used by scientists to murder. It is my intention to bring to light the positive benefits of stem cell research as well as counter the claims used by many Pro-life groups who believe the scientists driving this

Researches are continuously looking for ways to cure and treat all kinds of diseases, so why are there limits being put on the kinds of treatments that can be used to treat or cure a disease? Embryonic Stem Cells can be used to treat many different diseases, but some people have their opinion that using these stem cells in medicine is unethical because they are coming from a human embryo. There are countries that have banned the use of embryonic stem cells in medicine, and in America there are people arguing that it should be banned here. But what about all of the lives these stem cells are saving, what if research continues and these embryonic stem cells end up being a cure to a disease? With this in mind, human embryonic stem cells

The society has evolved over the decades. Medical advances, greater technologies, better understanding of the world around us, the sky is the limit! The progression of a society is astounding from where it was just twenty years ago. One is able to do things that the forefathers would have never dreamed! Science has discovered ways to travel to the moon and back, reach some of the deepest depths of the oceans and discover new species, and drive hybrid cars. The achievements of today’s society have reached a new high; however, with great achievement comes great questions of ethics.

The phrase “stem cell” calls to mind images of controversy: Pro-life picketers outside abortion and in-vitro fertilization clinics, patients with chronic disabilities waiting on a cure, scientists in a lab experimenting with a petri dish. These cells offer unimaginable opportunities for regenerative medicine because they can retain the ability to differentiate. Stem cells are classified as either adult or embryonic. Embryonic stem cells can

Since the Middle Ages, and eras before that; diseases and cancer were ubiquitous in this dark world. Until that is, we went through scientific and medical breakthroughs in the Modern Era. We are now drawing on that drawing board, and that would be Stem Cell Research. The affirmation of Stem Cell Research should be amicable, religion should not hinder us away, as there are other ways to move forward without it being unethical. The potential of Stem Cell Research is very high and will be the torch for this era.

The idea of a chimera, a cross between species, has been around since the mythological creatures of ancient Greece, such as the centaur (a man’s torso with a horses body) and the griffin (the wings, head, and claws of an eagle and the body of a lion). Today, due to our advances in biotechnology, we are seeing this mythology become a reality, but in a different respect. Human-nonhuman animal chimeras are being developed by injecting animal blastocysts with human embryonic stem cells. The cells need to be injected at the right point in development, after the body plan of the animal has formed and before the immune system develops. It is done at this time to avoid
