Researchers believe that understanding basic stem cell biology along with the pathophysiology of human diseases that can be targeted would bring stem cell therapeutics closer to clinical applications (Lindvall and Kokaia, 2006). These ideas definitely seem promising, but, embryonic and adult stem cells to be used for these therapies come with their own set of pros and cons. Because of a difference in their potencies, there is a variance in the ability of these two cell types to form differentiated cells in the body. Embryonic stem cells are pluripotent and when provided with the right set of conditions, can give rise to any cell type in the body whereas adult stem cells are limited to cell types of the tissue from which they are derived.
Embryonic stem cell therapy is still not favored because there is a high risk factor of tissue rejection after transplantation. Current stem cell therapies focus on highly plastic autologous adult stem cells (cells that are derived from one’s own body - this reduces the chances of tissue rejection) and are either very expensive or mostly experimental (under trials). But, obtaining adult stem cells from mature tissues is challenging and maintaining their cultures in vitro is even more difficult than embryonic stem cells. Culturing becomes an important aspect because large number of cells are required for stem cell

Essay on Adult Stem Cells

Adult stem cells, also known as somatic stem cells, are unnamed cells found throughout the body that have the potential to divide into different cells to replenish dying cells and regenerate damaged tissues. Adult stem cells can be found in both children and adults. The research and therapy in adult stem cell does not require the destruction of an embryo unlike that of embryonic stem cells. Consequently, adult stem cell research is the less controversial of the two. It is a known fact that both areas…

Pros And Cons Of Stem Cells

Mckennah Curry April White 1st Block 24 Apr 2017 Stem Cells: Good or Bad? Today, stem cells are very controversial, but what most people don’t know, are the benefits to stem cells research. Stem cells have the capability to turn into many different types of cells in the human body during the pluripotent stage, which is the first three to five days. Consequently, some say that stem cell research is “playing god” and “messes with human life,” but stem cells are used in so many ways and in different methods…

Essay about Stem Cell Research

January 5, 2015 Stem Cell Research What are stem cells and why are they so important? Stem Cells are cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells. Stem Cells can be found in the brain, heart, skin, organs and spine. There are two types of stem cells, adult stem cells and embryonic stem cells. Stem Cell research is exceedingly useful in our society because it can help cure many diseases and help the injured. Stem cell research can contribute…

Stem Cell Essay example

A stem cell is an undifferentiated cell, which retains the ability both to keep dividing for self-renewal of its population, and to become specialized in certain conditions. Embryonic stem cells occur in the early embryo, and have the ability to differentiate into any of the 200-plus types of specialized cells in the eventual body. Adult stem cells occur in certain tissues where they multiply rapidly as part of ongoing maintenance. In the bone marrow they produce millions of different blood cells…

Embryonic Stem Cell Research Ethics

Embryonic stem cell research, which has the ability and opportunity to be a platform for numerous medical breakthroughs in the never ending puzzle of the human body, involves the intentional altering of a human embryo in it’s developmental stages, thus effectively changing the genome of the future male or female, for various reasons. When viewed through the eyes of the practical audience, embryonic stem cell research is a truly revolutionary process that should not only be allowed to be applied,…

was the use of stem cells. In the 1980s, scientists developed a method to derive stem cells from an organism. Stem cells are “cells with prolonged self-renewal capacity and…[have an] ability to differentiate into multiple cell types” (Lindvall). This new discovery opened many doors for medical research, but it also caused conflict to erupt. There are two types of stem cells: tissue-specific stem cells and embryonic stem cells. According to the International Society for Stem Cell…

The Research Of Stem Cells And Treatments

The Research of Stem Cells and Treatments Overview Sufficient research studies has shown that stem cells could be used for many reasons in the human population. Those undifferentiated cells are known to have the ability to change into specialized cell types. Further investigation will be shown about how those stem cells work, and how they may cure cancer, diseases, and other health problems. The investigation includes embryonic stem cells, adult stem cells, and umbilical cord blood banking. Positive…

Stem Cells Essay

What are stem cells? Stem cells are the master cells of the human body. They can divide to produce copies of themselves and many other types of cell. They are found in various parts of the human body at every stage of development from embryo to adult. Stem cells taken from embryos that are just a few days old, can turn into any of the 300 different types of cell that make up the adult body. What types of stem cell exist? Stem cells can be classified into three broad categories, based on their…

Stem Cell Research

Introduction Stem cells are undefined cells with the potential to become any type of specialized cells. Stem cells can be derived from embryos, fetuses, and even adult cells. Stem cells can be used to replace tissue that is damaged, or even destroyed. If used to its full potential stem cells can help to fight the effects of aging. Stem cells draw in a mass of controversy and issues on many fronts both scientific, and moral. Stem cells could eliminate the problems thought to be unsolvable, and better…
