Stem Cells Research the Regeneration of Medicine
Stem cells research is one of the most powerful areas of medicine that is both researched and passionately argued. The web page of National Institute of Health (NIH) describes that stem cells are unspecialized cells that are capable of renewing themselves through cell division and they can also be induced to become tissue or organ-specific cells with special functions. Stem cells have the potential to develop into many different cell types in the body during early life and growth. Many individuals believe that there are ethical concerns with stem cell research because they come from destruction of perfectly good embryo however stem cells can be used for cell-based therapies, heart

Stem cells can be used to regenerate a heart for patients that are suffering from heart failure. Liao and Tse in their article for stem cell research & therapy Which was published by National Center for Biotechnology Information (NCBI) mentions that “Heart failure (HF) due to loss of cardiomyocytes caused by myocardial injuries, especially myocardial infarction (MI), is the leading cause of mortality and morbidity worldwide” (1). A myocardial infarction is heart attack which is just an obstruction of blood flow to the heart muscle which can be fatal which is why Liao and Tse in their article discuss two different types of stem cells: multipotent stem cells (adult stem cells) and pluripotent stem cells as potential cell sources for heart regeneration. Current treatments and therapies can only reduce the loss of cardiomyocytes which are cardiac muscle cells but are unable to replenish the permanent loss of those cardiac cells. The most common curative therapy is heart transplantation for severe heart failure, but this therapy is likely in a minority of heart failure patients due to limited organ supply. Under those circumstances “cell-based therapies using multipotent stem cells (adult stem cells) and pluripotent stem cells
Stem cells are cells that have the potential to develop into different types of cells in the body. Stem cells also act as a repair system for many tissues in the body by dividing repeatedly to replenish other cells within a person (National Institutes of Health). Stem cell research seeks to further the advancement of the use of stem cells as well as to find an ethical way to study them. In November 1998, researchers found a way to isolate and culture human embryonic stem cells, (Bevington 2005). The ethics of stem cell research has been debated over the years and some people fully support the use of stem cells, whereas others are completely against the use of stem cells. This has been an ongoing battle for scientists over the span of two decades prior to the 1998 finding.
A stem cell is a cell in the body that can differentiate into almost any other type of cell in the body. Stem cells come from sites in the bone marrow, as well as the tissues of developing fetuses. The most controversial issue in stem cell therapy is the use of fetuses for their stem cells. Scientists want to clone human embryos, and use the stem cells long before the embryo matures (when it is only about 36 cells). This causes a large amount of unease in society, because people fear that stem cells and therapeutic cloning will lead us into disgusting and horrible experimental practices, as well as therapies. Most people in America do not want this horrible vision of the future to come
Stem Cell research and its funding have caused a lot of controversy throughout the past years. Stem cells are cells that are present in all living organisms. These cells have the potential to grow into any type of cell, including blood cells, nerves, muscles, and pancreatic cells. Stem cell research is essential because of the beneficial aspects it has to offer. Stem cells could potentially treat conditions such as Alzheimer 's, Parkinson 's, birth defects, strokes, Diabetes, cancer, and help in the reconstruction of severely damaged organs. Although stem cell research withholds great potential for many medical advances, a lot of controversy surrounds the sources and methods of obtaining stem cells and the possibility of improper usage of the knowledge acquired from research and experimentation. It is necessary for scientist to continue research as well as recognizing any ethical issues that may be present.
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 according to scientists might be the key to saving lives due to organ failure, brain damage or even heart problems. The idea is stem cells provided by fetuses that have been aborted typically
Stem cells are basically the building blocks of life. Some type of these cells can be engineered into any type of cell in the human body. There are three types of stem cells currently. Adult or somatic stem “cells can generate replacements for bone and muscle cells that are lost through injury, disease or normal wear and tear.” Another type of stem cells are embryonic stem cells. Embryonic stem cells “are “starter cells” that can be coaxed into becoming any of the specialized cells of the body, meaning they are “pluripotent.” The final type of stem cells are induced-pluripotent stem cells. Induced pluripotent stem cells “are adult stem cells that have been genetically altered to behave like embryonic stem cells”(National Institute of Health). Due to the advancement in medical technology scientists and doctors alike are now able to use stem cells for a variety of reasons like research and also in patient care. The benefits of this research can lead to the cure of diseases like diabetes, some cancers, and even neurodegenerative diseases like Parkinson’s Disease and spinal cord injuries. The controversy behind stem cells lie from where these stem cells come from. The source of stem cells are plentiful. Some stem cells can come from human embryos that are a few days old. Stem cells can also be engineered in a laboratory setting using the cells from human embryos. Also there are certain stem cells that can be harvested from adults and
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
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
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
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.
The groundbreaking scientific research underway happening this century is revolving around the field of regenerative medicine, specifically stem cell research. To begin to discuss whether or not stem cell research should be scientifically funded we must understand what stem cells are. According to Jordan Saltzberg, author of “The Current Embryonic Stem Cell Research Federal Funding Policy,” embryonic stem cells have the possibility to reproduce and continue to grow and also form any type of specialized cell unlike adult stem cells (2). Since the embryonic stem cells (hESCs) can form any specialized cell they are more valuable than adult stem cells (hASCs). Saltzberg has also stated, stem cells are present throughout a person 's life but are first found in the embryo (2). This shows that one day we may be able to use human adult stem cells instead of embryonic stem cells. Human embryonic stem cells are, for now, the most promising subfield of regenerative medicine. Stem cell research is debated by many different groups, for example the church, government, and everyday people. The majority of religions along with all of their followers believe the research to be unethical, whereas the government and scientific community think that it is vital for new scientific discoveries. Despite the
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.
Researchers successfully attained embryonic stem cells from the embryos of mice in 1981, which led to the discovery of this process in human beings in 1998 (National Institutes of Health, 2001). Embryonic stem cells are derived from an in vitro embryo between five days and seven weeks. Regenerative medicine can benefit greatly from the characteristics of embryonic stem cells. This process enables damaged organs and tissues to heal themselves with the help of implanted stem cells matching the organ (Hunziker, 2010, p. 1). There are two traits
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
Stem cell research is one of the most promising and controversial topics is the past few decades. Stem cells were discovered by a group of scientists in 1981 by deriving embryonic stem cells from mouse embryos. The discovery of stem cell derived from mouse embryos then progressed to the discovery of deriving and creating stem cell from a human embryo is 1998. In 1998 when scientists discovered a way of deriving stem cells from a human embryo is when the controversy began. The main controversy of stem cell research is the destruction of an embryo for sceintific and medical purposes. Other controversies are whether federal governments should fund and support research is ban the use of stem cell for medical and research purposes. Various religions
