stem cell research Essay

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.

Now adult Stem cells are found in many place of the body such as teeth, bone marrow, in the heart , as well as skeletal muscles, in your gut and even your liver. but not all organs and tissues.don't get me wrong there are some Stem cells in specific tissues of your body. and that’s where they will stay for years upon years. and while they are there they will divide and create new cell when the tissue has been

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.

In November of 1998, a group of researchers announced that they had successfully isolated and grown a special kind of cell with the potential to develop into virtually any kind of human tissue. The scientists had made the discovery of embryonic stem cells. The discovery was considered to be an innovative

Attempts were made to fertilize mammalian eggs outside of the human body and in the early 1900s, it was discovered that some cells had the ability to generate blood cells. In 1968, the first bone marrow transplant was performed to successfully to treat patient’s severe combined immunodeficiency. There have been many stem cell discoveries since the early 1900’s but the two majors were in 1998 when, Thompson, from the University of Wisconsin, isolated cells from the inner cell mass of early embryos and developed the first embryonic stem cell lines. Then, in 1999 and 2000, scientists discovered that manipulating adult mouse tissues could produce different cell types.

Many, as of currently incurable diseases plague the Earth. Thanks to technological advancements and better understandings of cells, scientists believe that it may be possible to cure diseases by the use of embryonic stem cells. Embryonic stem cells are cells obtained from an embryo when they are only a few days old. Because they have only begun to differentiate, these cells have the capability of developing into any cell in the human body, and that's why they can be used for the progression of medicine. Scientists hope to cure some diseases but if that isn't possible they at least hope to create treatments using them.

In 1963, Canadian researchers, Ernest McCulloch and James Till directed tests on mice bone marrow and watch that diverse platelets originate from an uncommon class of cells. This is one of the primary bits of confirmation of blood immature microorganisms which is better known as stem cells (HISTORY OF STEM CELL RESEARCH — A TIMELINE).Canadian disclosure of undifferentiated organisms has manufactured the premise for further foundational stem cell research in different ranges, which is turning out to be more well known and urgent these days to comprehension the human body. All through the twentieth century undifferentiated stem cell exploration was based off of more subjective work instead of quantitative, the way that two Canadian researchers changed the point of view of perception in this field comprehensively resounded in the mid 21st century and has made the field of foundational stem cell research significantly more essential to comprehension the recuperating example of specific cells that were once thought to be basic, for example, nerves and spinal cells. The last motivation behind why Canada is vital to the field biology is its effect on therapeutic innovation.

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.

In 1981, Scientists found a way to extract embryonic stem cells from mouse embryos. Years later, in 1998, a method to extract stem cells from human embryos and grow the cells in the laboratory was discovered. The main purpose was to use the cell's ability to regenerative as a method of treating diseases. As time went by, people started to oppose the idea of using embryonic stem cell for research. So, funding that helped continue research on embryos started to decrease. This conclusion came from some people considering that embryonic stem cells research was similar to killing babies. Others thought that research on adult stem cells was less controversial than research on embryonic stem cells. Embryonic stem cell research leads to the

Firstly, what even are stem cells? Stem cells are cells that can turn into many different types of cells throughout your bedy. Think of it like a mother cell creating endless amounts of children. There are two kinds; pluripotent, ones that can turn into basically every cell in the body, and multipotent, ones that can only for a small number of cells.

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

Stem Cells can have a colossal impact on the human race if researched enough and used to their full capability. As President George Bush said "A n ethicist ... told me that [a] cluster of cells is the same way you and I, and all the rest of us, started our lives. One goes with a heavy heart if we use these [embryonic stem cells], he said, because we are dealing with the seeds of the next generation." These cells can transition into any cell it would like (AAPI). In the 1800 's stem cells started to get researched and that is when it was discovered that the cell could form other types of cells. In early 1900 's European researchers noticed that white and red blood cells came from the first cell. In 1963 was the first writings of the stem cell renewing of transplanted mouse bone marrow cells were documented by Canadian researchers Ernest A. McCulloch and James E. Till. Adult stem cell research into animals and humans have been ongoing

Stem cell research has cultivated a new, miraculous study in the health field. The study has led to an increase in curing diseases over the past couple of decades. Before stem cell research, diseases were destroying and devastating lives continuously on end. With the use of stem cells in modern time, diseases are no longer taking control of lives. The innovation in biomedical technology, such as stem cell research, has greatly impacted the understanding of how diseases can be treated, how drugs can be tested, how more careers will be available in the future, and how newborns can safely provide help. Stem cells are cells that give rise to all other cells in the body with a specialized function. Blood cells, muscle cells, and the cells of internal organs all form from stem cells. There are several sources of stem cells found in the body. Two known sources of stem cells are the embryonic stem cell and the adult stem cell. Embryonic stem cells are found in embryos three to five days old. This means that they are able to divide into more stem cells, or become any specialized cell in the body at this early stage. Adult stem cells are rare, but not uncommon. These adult stem cells are found in low numbers amongst all adult tissues. However, these cells are most commonly found in bone marrow and fat. Unlike embryonic stem cells, adult stem cells have limited ability to breeding other cell

The second article titled “Transforming Healthcare Through Regenerative Medicine” written by Jessop, Z. M. et al. (2016) starts with a timeline of stem cells and dates back to 330 BC. When Aristotle observed a lizard regenerate its tail. In 1712 a crayfish limb regeneration is observed; 1956 was the first successful bone marrow transplant. This chart continues to date milestones in research all the way to 2014. These dates do follow a few dates that were given in the article “Everything worth knowing about.. stem cells”. They both have the same information for the years 1961, 1981, 1998, and 2006. This gives the reassurance and reliance of a web article compared to an authoritative resource.

According to the Merriam-Webster dictionary a stem cell is “a simple cell in the body that is able to develop into any one of various kinds of cells (such as blood cells, skin cells, etc.).” There are two types of stem cells, embryonic and adult. The adult stem cells can can be found in brain, bone marrow, blood, etc. The embryonic stem cells come from a four to five day human embryo during the blastocyst phase (Crosta) . The controversy behind the topic usually stems from the embryonic stem cell research. People argue over whether an embryo at this stage is considered a human or a scientific sample. US news held a poll and these were the results; “Almost three-quarters (72 percent) of the adults surveyed believe that scientists should be allowed to use embryonic stem cells left over from in vitro fertilization procedures to search for potential treatments or ways to prevent diseases such as Parkinson 's disease, Alzheimer 's, diabetes and other conditions.” (Gardner). Although there is controversy behind stem cells, the majority of Americans support scientists in stem cell research. Stem cell research is beneficial because they can help treat Parkinson’s disease, replace or repair damaged organs, and they specialize undifferentiated cells.
