Stem Cell Research Essay

Stem cell research has been quite a controversial topic since its origin in the 1960s by Gopal Das and Joseph Altman. Of course, anything that uses a human embryo would be. Stem cell research could open a vast number of new doors for modern science, it could let us test new drugs, one of which could be the unfound cure for AIDS or Alzheimer’s disease. However, this branch of science comes at a high price, the price of a human life that is only five to six days

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.

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 cells are special cells that have the ability to regenerate and repair damaged tissue. Embryonic stem cells appear to possess the ability to become almost any tissue within the body. This, in theory, means that a cell could be taken from one section of an embryo that may have become a part

While embryonic stem cells can restore and repair tissue, there also can be a risk when inducing them into

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

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.

A cell that has the ability to develop or duplicate into any other type of cell the body may have whilst still alive, whether it be a specialised cell or other stem cells, by using the cell-division cycle, is what we call a stem cell. Stem cells can be uncovered from various sites around the body, such as amniotic fluid, which can be retrieved during a pregnancy, placenta and cord tissue during the development of embryos, umbilical cord blood that is saved after the umbilical cord is cut, teeth, embryos that are willingly donated during the blastocyst stage (4-5 days after fertilization), and adult bone marrow. Each of these stem cell types, wherever their source might be, holds the priceless competence to work as a huge medical advantage,

Adult stem cells, commonly referred to as somatic stem cells, have a primary goal of repairing the tissues in the part of the body in which they are found. These cells are found in so many different tissues and organs, and are named by where they can be found, or by which tissues they help regenerate. The area in which the stem cell resides in within these structures is known as a

controversial topic of embryonic stem cell research. Some will say that using stem cells to

In the correct conditions, stem cells have the ability to divide, forming daughter cells. These daughter cells either become new stem cells or specialised cells with a precise role, such as blood cells, bone or heart muscle. No other type of cell in the human body has the capability to produce new cell types.

Stem cells are the basic building blocks of our body; they are the built-in first aid kit that repairs our body after damage has occurred (Freudenrich & Watson, 2004). Our body naturally supplies stem cells, but as our body matures, the stem cells do as well. These mature stem cells become specialized to a specific type of tissue and cannot be used for any other place in the body. As we get older, our body produces less of these stem cells, which causes adults to heal less quickly than children.

Stem cells are cells which can be specialised to become any type of cell which is required in the body.

Stem cells are Cells with the ability to divide for indefinite periods in culture and to give rise to specialized cells. So, to put that in clearer terms, stem cells parents told them they could be anything they wanted to when they grew up, and so they did. Since stem cells are so versatile

     Aside from just not having proven to be an effective means of curing sicknesses, embryonic stem cells are obtained from in vitro fertilized embryos as well as aborted embryos. The problem with in vitro fertilized embryos is the researchers have a tendencies to make too many of them, in mass amounts. Their resolution to this is to freeze the embryos, to slow the death process. So, essentially, these researchers create the living embryo, study it, freeze it, pull some cells from it, then let it die (Center for Bioethics and Culture).
