Stem Cell Research Jason Bernard BIOL-10000 July 26, 2015 Introduction In this essay, I hope to analyze both sides of the debate, and also learn more about the topic and share that information. Prior to researching this topic, I feel that any research that can help prevent or cure diseases, than the research should receive full funding and support. What Are Stem Cells? Stem cells were first discovered in the 1960s by Dr. James Till and Dr. Ernest McCulloch, professors at the University of Toronto. (Panno, 2010) Stem cells are microscopic cells that are essentially blank or unspecialized cells that can divide through mitosis. (“Frequently Asked Questions”) Stem cells can then become specialized cells through plasticity. A lot of what is currently known about stem cells is from studying rodents. Scientists use what they have learned from working on these animals to better learn how stem cells work. (Panno, 2010). There are two main types of stem cells that are used for research purposes, adult stem cells and embryonic stem cells. (Crosta) Adult Stem Cells Adult stem cells are found in various places throughout the body. Adult stem cells will begin to divide once exposed to disease or muscle injury. These cells have been used for many years now, from stem cells that were found in bone marrow. Scientists first found that two kinds of stem cells existed in bone marrow. The first type, called hematopoietic stem cells, are able to differentiate to different types of blood
Stem cells are tiny little balls of cells which are undifferentiated cells that can separate into particular cell sorts. Scientists and researchers focus on two main types of stem cells; Adult stem cells which come from the brain, spinal cord and most parts of the body and embryonic stem cells which are cells that are extracted from embryos. Researching on stem cells show that they could potentially save millions of lives by enabling scientists to develop ways to treat and cure some of the most degenerative conditions. So why not use them?
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
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.
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.
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.
There are a few different kinds of stem cells. These different type of stem cells depends on where it came from. As of now, there are only a couple sources for stem cell’s. The first kind of stem cells are adult stem cell. These adult stem cells can be obtained from specialized tissue in both children and adults. Since these cells are older, they are further along in the differentiation process, meaning they can only change into a few types of cells instead of the 200 that comes with embryonic stem cells. This is also called being pluripotent. (Miller
Adult Stem Cells are not only found in adults. All age groups contain the adult Stem Cells.
Stem cells are what make up the tissues and organs in our bodies. They have the potential to differentiate into different types of cells (Frequent), which make them so exciting to scientists. There are two types of stem cells adult stem cells and embryonic stem cells (Frequent). Although adult stem cells are used in some treatments, they can only differentiate into the same type of tissue they came from, for example an adult stem cell taken from a muscle
What are stem cells? Stem cells are immature cells that have the potential to become specialized as a different cell throughout the body. In simpler terms stem cells are cells that can become another cell and help a damaged part of the body. There are 2 different types of stem cells adult stem cells and embryonic stem cells. Adult stem cells are found in adults, children, infants, and umbilical cords. Obtaining adult stem cells from these sources does no harm to them. Embryonic stem cells are different from adult stem cells by how they are obtained. Embryonic stem cells are obtained through miscarried or still-born fetuses. Many people are against embryonic stem cells because of the religious and ethical aspect. But in clinical trials stem cell research has proven to be beneficial. Stem cell research is the studying of stem
There are two types of stem cells that are regularly used in research. Each has a different set of characteristics and therefore is able to perform different functions in the body. The two major types of stem cells are adult stem cells, also referred to as somatic stem cells, and embryonic stem cells, which are the focus of major controversy. The areas in which they differ are important to understand since the stem cell debate that has raised serious questions of medical ethics. The primary reason stem cells are so highly demanded is that they retain the ability to develop into many different types of cells; they allow one single cell to give rise to many other types of cells. An example of this is found in bone marrow; the stem
Since the 19th century, scientists have been researching stem cells as cures for diseases. It was in the mid 1800s that it was discovered that cells were the building blocks of life and that there were some cells had the ability to produce other cells. (Murnaghan). With this discovery, many scientists set out to find the abilities stem cells were capable of having. The first use of the term “stem cell” has dated back to as early as 1868 by a German biologist named Ernst Haeckel. (Ramalho-Santos and Willenbring 35-38). Stem cells are cells that either have the ability to divide and are able to become more identical stem cells or they could form specific cells of somatic tissues. With stem cells there are two types: embryonic stem cells and adult stem cells (Hum. Reprod. (2003). Embryonic stem cells are obtained from embryos. Many people oppose of
Stem cell research is a controversial topic and this paper will talk about both sides of the controversy. The controversy started back in 1998 when the first successful culturing of human embryonic stem cells was performed. The research surrounding stem cells has been the center of a huge debate mainly because of ethics and morals.
Stem cell research is one of the most widely expanding areas of scientific research being conducted all over the world today. In basic terms, stem cell research is the research of stem cells; however in actuality is much more complicated. A stem cell is a cell with the ability to develop into any of the cell types that make up the tissues and organs of the body. This makes these cells highly useful and provides limitless potential in the field of regenerative medicine.
. 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.
As the smallest unit of life, cells make up every organ and body part of a living organism. Among various types of cells of human bodies, a stem cell can turn into any type of specialized cell of human body. A stem cell is a cell that has the ability to develop into any conceivable different kind of specialized cell type. The existence of a stem cell was first discovered by Drs. James Till and Ernset McCulloch from Canada. A stem cell can be distinguished into two types: adult stem cell and embryonic stem cell. An embryonic stem cell also known as pluripotent stem cell is a type of stem cell that has the ability to develop into any cell type of the body. An adult stem cell also known as somatic stem cell and multipotent stem cell, retained from body tissues can only turn into a certain type of cell from the same organ from which it originates. A stem cell is currently one of the hottest topics in the field of biology. Due to its therapeutic uses and so strong treatment solutions tailor-made to various illnesses, stem cell is regarded as one of the promising fields in biology to many scientists. [1,2,3]
