Embryonic Stem Cell 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).

Embryonic stem cells have numerous and amazing uses. Stem cells are unspecialized cells with the ability to replicate and renew themselves. They have the ability to transform into many kinds of cell types within the human body. They divide and create a new cell, having the potential to infinitely replenish cells. There are two types of stem cells: embryonic and somatic. Embryonic stem cells are from a fetus and can become all cell types in the body. Somatic stem cells are from an adult and can become only certain things due to the origin of the cells. Scientifically

Stem cells are cells that are not specialized, and can become many different kinds of human tissue. There are two types of stem cells: Adult stem cells, which cannot form all tissues of the body, are found in

A stem cell is defined as a cell that can change into a different type of cell. Stem cells are different from other cells because from the start they do not have specialized functions. Embryonic stem cells are found within the blastocyst (embryo), which is just a tiny package of

Stem cells are a type of cell that basically always divide in order to replace other cells in the body. They are different from normal cells because once they have first divided into a new stem cell, they can become another type of cell, such as a muscle cell or blood cell, tissue, or they can continue being a stem cell. They also can remain inactive for a period of time, yet they can still divide into new cells whenever they are needed.

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.

There are two main types of stem cells. The first is the Embryonic stem cell. Embryonic stem cells are obviously found in embryos. Human embryonic stem cells are generated by transferring cells from a preimplantation-stage embryo into a plastic laboratory culture dish that contains a nutrient broth known as culture medium. Many people are against embryonic stem cell use because by extracting stem cells from an embryo it destroys it. Also opponents of the research argue that embryonic stem cell

There are a lot of potential uses of stem cells, but there are obstacles that we need to go through first. Stem cells can be used to test new drugs that scientists make. We could generate healthy heart muscle cells with stem cells. Injected cells could repair things in the body by secreting growth factors. Before scientists start

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.

Adult stem cells, like embryonic stem cells, have the ability to differentiate into several more specialized cell types, but the potential number of cell types is far smaller than that of an embryonic stem cell. Embryonic stem cells, by nature, eventually turn into every type of cell in the body, whereas adult stem cells will only turn into a few cell types. For example, a blood stem cell, one type of adult stem cell, will eventually turn into one of eight types of specialized blood cells (Jordan 116.3).

Adult stem cells are not necessarily derived from adult human but merely not from embryos. These stem cells can found in bone marrow, connective tissues, hair follicles, umbilical cords and other areas of the body. It is said that these cells have been used to treat an estimated 11,000 patients in the United States in the past two years alone, and over 70 diseases, including Parkinson’s and diabetes. (Pence, 2009) There have been 0 recorded successful treatments achieved by the use of embryonic stem cells. As well, stem cells from umbilical cord blood have been used to treat 65 diseases such as leukemia, and lymphoma. (Sweat,

Amniotic stem cells are found in the amniotic fluid around a child just before it is born (Mayo Clinic Staff). Amniotic stem cells are primarily used for organ regenerations because there is a very rare chance that they will cause an immune system attack. Embryonic stem cells make up an entire embryo as it is developing. Embryonic stem cells, also known as blastocysts, start forming into vital organs, such as the heart and lungs, before the embryo is even a week old ("Stem Cell Information"). Adult stem cells, called somatic stem cells, are found in anyone who is no longer a fetus. They could be found in children and fully grown adults. Adult stem cells, however, are limited to what they can produce. They can only maintain and repair the tissue they are For example, the stem cells in adults can only be found in bone marrow, blood cells and fat cells (Mayo Clinic Staff). Adult stem cells still have the potential to be useful for society. Researchers are trying to alter the genes inside of an adult stem cell to make it more adaptable like an embryonic cell ("Stem cells: What they are and what they do"). These stem cells are called induced pluripotent cells and they cannot be used for curing any diseases because when you change the genetic makeup of something, you cannot always get the predicted outcome, so further research must be

In addition to research, these types of stem cells are used to restore and repair damaged tissue in all kinds of diseases. Embryonic stem cells are so useful because they have pluripotency, which means that they can differentiate into any human cell type. The cell types that they are commonly induced in are neural, heart, liver and insulin pumping beta cells that are similar to the pancreas. Since these embryonic stem cells can be differentiated into so many types of cells, they are able to treat diseases like: Alzheimer's, Parkinson's, diabetes and many more.

Stem cells are cells that have the potential to become almost any cell in the human body, during the early developments of life. Stem cells have the possibility to generate all of tissues within a human as well. Each stem cell can either stay a stem cell or become a more specialized cell. The stem cells that are unspecialized are capable of renewing themselves or possibly being induced to become organ specific cells or tissue cells with special functions. Most stem cells have a constant supply to replace other cells that are injured, diseased, or even aged.

Adult stem cells are thought to be undifferentiated cells. According to the NIH, the main goal of adult stem cells is to repair and renew cells and tissue in the body (Stem Cell Basics). Compared to embryonic stem cells, adult stem cells origin is undetermined. However, scientists are excited over the recent discoveries emerging from research. Researchers have found adult stem cells are in the brain and heart where they believed stem cells would not exist. These findings can continue to help scientists develop research in which adult stem cells could become the basis of transplantation-based therapies (Zawada and Kalumuck). If scientists are able to control these cells in laboratories, they could develop transplant stem cells that could even rejuvenate a heart. If the heart is rejuvenated it could circumnavigate a heart transplant (Zawada and Kalumuck). Other examples of conditions that could be cured with rejuvenation are Diabetes, Alzheimer's, Parkinson's, strokes, burns, spinal injuries, and more (Stem Cell
