Stem Cells And Its Effect On The Body Essay

The unique properties of stem cells are that they are capable of dividing and renewing themselves for a long time. This means they can multiply as many times as they want and grow into lots of different types of cells. They are also under certain physiologic and experimental conditions. They can produce tissue or organ-pacific cells with special functions. There are three classifications of stem cells. There are Totipotent, Pluripotent and Multipotent. Each one of these classifies stem cells in a certain way. Totipotent cells can change into all cells types, Pluripotent cells can change into most cell types and Multipotent cells can change into certain cell types. There are two major types of stem cells, Embryonic and Adult. Although they are both major types of stem cells they are very different from each other. Embryonic stem cells can change into all types of cells and Adult stem cells can change only into certain types of cells. Embryonic stem cells are classified as Totipotent and Pluripotent. Adult stem cells are classified as Multipotent. Another reason why Embryonic and Adult stem cells are different is because they have

Stem cells are a special group of cells found in all multicellular organisms. What makes them unique and different from other cells is the fact that they are unspecialized and have the potential to differentiate into diverse cell types while still maintaining the ability to replenish themselves. Generally, these cells are divided into 2 broad categories – the embryonic stem cells that are derived from the inner cell mass of the blastocyst and the adult stem cells that are harvested from the bone marrow, umbilical cord blood or the adipose tissue of an adult.

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

Tissue specific stem cells can create different cells for different organs and are obtained from different organs and tissues. Embryonic stem cells can increase every cell type in an adult body and are obtained from the blastocyst, a ball of cells formed a couple of days after an egg cell is fertilized. Mesenchymal stem cells are typically obtained from bone marrow and can produce bone and fat cells. Induced pluripotent stem cells are made in a science lab by changing tissue specific cells into embryonic cells and they help scientists research normal development.

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.

Stem cells are the first form of the cells of a multicellular organism and are undifferentiated cells. There are 3 different types of stem cells. This includes Embryonic stem cells, tissue-specific stem cells, induced pluripotent stem cells. Stem cells are capable of self-renewal.They can divide and produce cells that can to become more specific cell types, tissues or organs.

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

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

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

The stem cells that originate in the inner mass found in embryos a few days old are grown in the laboratory and are referred to as embryonic stem cells. A branch of these cells are embryonic germ cells, and these are derived from egg and sperm cells in a five to ten week old fetus. Both of these types of stem cells are pluripotent. In embryonic stem cells, the blastocyst cells divide and eventually develop into all of the tissues and organs of human beings. Embryonic stem cells are capable of being grown in the laboratory from blastocysts and made to differentiate into nerve, liver, muscle, blood, and other cells. (Morgani, et al.

Stem cells can become many different cell types. There are three main types; totipotent, pluripotent, and multipotent. They have already have been successful in treating some diseases and have the potential to cure many other diseases. Stem cells have also been very useful in drug testing. However they have caused a lot of controversy, but some technology has helped settle this controversy.

Stem cells have a plethora of side effects that over powers the benefits. The ability to differentiate is known as plasticity, and it is thought to only be at its greatest in embryonic stem cells. In order for the embryonic cells to be of use they must be fertilized, after which, the stem cell is removed, destroying the embryo. Stem cells can be used in adults; however it is believed through the consensus of the medical community that the plasticity of embryonic stem cells is not even closely matched by those of adult stem cells. The general idea is that “adult stem cells have a limited capacity to differentiate (Solter 8).” Adult stem cells are already stuck in their ways, which makes it useless, in a way. They can only reproduce the same cell type that they originate from. Thus, despite the prospecting medical leaps that this technology can provide, the process of how to obtain the embryonic stem cells overwhelms the benefits by far.

Stem cells can be classified in one of three categories: embryonic stem cells, somatic or “adult” stem cells, or induced pluripotent stem cells. Embryonic stem cells, as the name suggests, come from embryos. Only relatively recently have stem cells actually been made from human embryos; from 1981 until 1998, stem cells were grown exclusively for laboratory mice from mice. Today, however scientists are able to grow stem cells through a few techniques. One such technique uses embryos left over from in vitro fertilization. These embryos are willingly donated to research facilities. To obtain stem cells from actual embryos, scientists transfer cells from the existing embryo into a dish full of a culture medium that serves as nourishment to the cells. Here, the cells divide rapidly and can then be transferred into more culture dishes and allowed to grow further or be used in scientific research (U.S. Department of Health and Human Services). The acquisition of embryonic stem cells can be somewhat controversial. For instance, many believe that it is wrong to sacrifice embryos for stem cell research. However, many embryos used to create stem cells are ones that would have gone to waste in a fertility clinic’s freezer anyways. So instead of wasting the unused embryos, we are putting them to good use and

Now as we all grow up we ponder the idea of what our profession will be and the same approach comes into play with stem cells. There are two main types of stem cells, which are embryonic stem cells and adult stem cells. An embryonic stem cell is a undifferentiated cell that can give rise to all of the bodies cells and your existence in whole by choosing its profession. While most cells can only recreate more of its own kind;

The way that stem cells work, which includes both embryonic and non-embryonic, is interesting in a lot of assets. Like all cells, stem cells need to perform cell division in order for them to probably function and do their jobs, so they need to go through things such as telekinesis mitosis and even meiosis. Embryonic stem cells start off in the blastocyst, or cell embryo that contains approximately 150 cells (MCS, 2013) MCS: Mayo Clinic Staff. After this occurs, the embryonic stems cells will then assemble healthy cells in order to block out or even discontinue old sick ones (MCS, 2013). Adult stem cells are a tad different then embryonic stem cells are as far as there development goes. In the adult stems cell’s development process, Rather than starting out as an egg or fetus, it is already found in your body in places like tissue, bone marrow etcetera, which means that you don’t have to create it like the embryonic stem, however, because of this they don’t have as much ability to differentiate (NIH, 2016). Embryonic stem cells are used, and researched to a much larger extent then adult stem cells due to the fact that adult stem cells are
