Stem Cells : The Origin Of An Organism 's Life Essay

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 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

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

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 multiple ways for stem cells to be obtained such as: Taking the cells from aborted embryos or fetuses, umbilical cords, adult tissues, or artificially creating embryos with a process known as a somatic cell nuclear transfer (SCNT). In this process “the nucleus of an egg is removed and replaced by the nucleus from a mature body cell, like a skin cell” (Arnes). Also known as cloning. However, creating embryos like this do not create stable stem cells. And taking stem cells from umbilical cords has the possibility to transfer unknown genetic disease and “has not yet demonstrated health and

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

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

We are aware of three sources from which we can obtain stem cells to perform the aforementioned functions. The first and most controversial method is obtaining the cells from the blastocyst, a ball of undifferentiated cells that are formed after an ovum is fertilized. These are created by a process called in vitro fertilization, a procedure that allows women with genetic or fertility issues to become pregnant. The second source that is bursting with stem cells is the umbilical cord. Scientists are able to extract something called T Blood cells, cells that deal with creating a sort of immune system for a collection of cells against external forces, from the cord blood of a newborn infant that are then either immediately preserved for later use by freezing the blood or the cells, or can be immediately used by an individual that needs the cells. The third and final source of stem cells are Induced Pluripotent stem cells, commonly referred to as adult stem cells. By extracting either the marrow or blood cells from adults, scientists are able to artificially induce these into unprogrammed cells than can take the form/responsibility of stem cells to form somatic cell lines such as nerves and muscle cells.

Stem cells can either be embryonic stem cells or somatic stem cells. Embryonic stem cells can be obtained from the inner cell mass of the embryo, a process which often results in the killing of the embryo.

Stem cells are undifferentiated cells that have the ability to become many different cell types by the process of mitosis and differentiation. Due to this unique property, many scientists are keen to researching and working with these cells. Furthermore, Stem cell is one of the most potential gates to curing diseases and developing new technologies.

Today, what I would like to talk about is stem cells, which is a kind of the most important cells because it is a foundation for the development and growth of other lots of different cell types. There are many other tissues they are working with internal repair system and they also can divide necessarily for supplement to other cells if they are still alive. But, the condition is different of stem cell, which has two major functions compare with other cell types, remaining a stem cell continually or transforming to other cells that have specialized functions like bone marrow cells, and they can divide and renew by themselves for a long time. Today, there are two main stem cells are used by scientists with many different ways: embryonic stem

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

The human body is made up of a million of cells. Each serving its own purpose, whether it be liver cells, skin cells, hair cells, etc. A stem cell is an immature cell that has the potential to become specialized into forms of cells throughout the body. The term stem cell is used to refer to a type of cell that not only has this function, but also has the ability to replicate itself. When a stem cell divides, it has the capability of becoming another stem cell or become a more specialized type of cell that performs a specific function in the body.
