Embryonic Stem Cells Essay

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.

In humans adult stem cells, not embryonic stem cells, have been used in therapies for more than forty years. People with blood disorders have used stem cell therapy to take the opportunity to improve upon their life. On the other hand, embryonic stem cells have a very high potential to treat or even cure numerous diseases like diabetes and heart disease. They are much more versatile in their usage compared to adult stem cells. Another practical use for embryonic stem cells is to treat damaged nerves ("Testing The Use…”). These nerves could have been impaired in a spinal cord injury. As of today, scientists have already performed stem cell transplants in people whose cells were damaged through chemotherapy of disease.

Athletics at college has been and continues to be a billion dollar industry. Over the past few decades, college athletics have increased the ratings and gained popularity across the world. Regardless of the type of sport being played, college athletics became a source of big money and a revenue surplus to the Universities. Colleges generate huge revenue, but the players are not compensated for playing.

Sports were created for the enjoyment of beings and friendly competition. Today society has shifted the friendly competition to more of a money based system rather than fun and games. The typical athletes’ road to success is starting from a young age, playing in high school, and then receiving a scholarship for College and all athletes overall objective is to constantly get better and play professionally. Universities have really manipulated athletes in the world today giving them “free education” for the exchange of their blood, sweet, and tears, while they receive revenue that athletes bring in yearly. It is very evident that College athletes deserve to be paid, and universities need to find a way to pay them a reasonably amount because

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

The difference between embryonic stem cells and adult stem cells is actually not difficult to understand. An embryonic stem cell is found in the Inner Cell Mass of a newly fertilized egg called an embryo. Embryonic stem cells are pluripotent. I will talk about that later as well. Embryonic stem cells are practically the star of stem cell research. Many scientists research them to try and figure out what stem cells are

Embryonic stem cells are undifferentiated cells from a human embryo which is the beginning development of a baby. Due to the cells being undifferentiated that gives researchers the opportunity to give them a function without problem. Unlike adult stem cells, which are differentiated, that doesn’t give as many opportunities because the area it came from for example a spine cell it has to be put in another spine or it can cause complications. But this is one of the most controversial topics in the science world today due to many not minding the use of embryos but others have religious reasons that say they aren’t allowed to use embryos.

First of all, it is important to stabilize that most stem cells are restricted to model a specific type of descendants. For example, dermis stem cells can only create skin cells, hematopoietic stem cells can only generate blood cells and so on. In contrast, embryonic stem cells have the capability to develop all type of

Stem cells are cells that have the ability to divide for periods of unlimited time and they can also provide a boost for the specialized cells throughout the body. Embryonic stem cells are derived from embryos, which is why they are called the embryonic stem cells. The embryonic stem cells also produce the very first cells of the heart, brain, and other major organs. However, the adult stem cells exist throughout the embryonic development and have the ability to renew themselves. The adult stem cells also have the ability to differentiate to yield some or all of the major specialized cell types of the tissue or organ (National Institutes of Health). Adult stem cells can be found in different types of tissues throughout the

In very simple terms, stem cells are cells that have the strong ability to become any number of other cells. “Stem cells are distinguished from other cell types by two important characteristics. First, they are unspecialized cells capable of renewing themselves through cell division . . . Second, they can be induced to become tissue-or organ-specific cells with special functions” (NIH 2002, 1). There are two extensive groupings of stem cells in which scientists primarily work with. These include embryonic stem cells and adult stem cells. Embryonic stem cells are “derived from the developing

Canute’s father was Sweyn Forkbeard, king of Denmark and Canute was the grandson of Polish ruler Mieszko. Canute the Great reigned over what was referred to as the North Sea Empire, which consisted of Denmark, England and Norway, from 1016 to 1035. Canute had to establish claim to the throne through an English successor once his brother Herald passed away without heirs. Canute was the second son after Herald, before Canute became the Anglo-Scandinavian king he was governing England when Saxon king Edmund died and created a growing empire, which led to the awareness of Canute as England’s king to all of England’s

Embryonic stem (ES) cells are stem cells that come from the undifferentiated inner mass cells of a human embryo. These embryonic stem cells are pluripotent, meaning that they are able to grow into all derivatives of the primary germ layers: ectoderm, endoderm and mesoderm. These cells usually come from human embryos that are in the early stages of development called blastocyst. These blastocyst have cells that have the ability and potential to become some or many different cells of the body. This of course depending on whether the cell is pluripotent or totipotent. Totipotent cells have the ability to become all cell types. Embryonic stem cells have the ability to grow indefinitely and maintain their pluripotency which can be used to treat or cure multiple diseases but due to the nature of the cells origin the use of these cells is controversial. Much of stem cell research controversy comes from religious based criticism, and the question: what point does a person consider life to begin?

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

Embryonic stem cells are derived from embryos; however, most embryonic stem cells are generated and fertilized through in-vitro fertilization in a laboratory setting, not within a woman’s reproductive system. Embryonic cell generation is by no means efficient, although once the stem cells are created, it is able to yield millions of embryonic stem cells from that one cell (“Stem Cell Basics”).

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).
