Cluster of differentiation

Although if cells are allowed to clump together to form embryoid bodies they will naturally begin spontaneous differentiation. Although, spontaneous differentiation is a good hint which shows that a culture of embryonic stem cells is healthy, it is not a good way to produce cultures of specific cell types and is quite time consuming. As a result, scientists try to control the differentiation of embryonic stem cells. They modify the chemical composition of the culture, change the surface of the…

Stem Cell Research While doing the research for this paper I found many reasons to be for and against this type of medical research. The main reason I am for this is it allows for the continuous research and development of new therapies and possible cures for the many diseases the plague our country today and in the future. This topic has been highly debated for many years and is still one of the most talked about topics in medical research today. It ask the ethical question should we allow…

Muscular dystrophy is an ailment that can have a very huge toll on the body. It is a group of congenital muscle diseases, in which muscle fibers are strangely vulnerable to mutilation and become increasingly weaker. In the late phases of the disease, fat and connective tissue often swap muscle fibers. This disease usually appears to be because of a hereditary shortage of the muscle protein, dystrophin. This group of ailments includes Duchenne's muscular dystrophy, Becker's muscular dystrophy,…

With a fascination of the brain since middle school, I have gradually developed an interest in neurology, especially concerning the study of brain tumors. It is fascinating to know that one tumor in the brain can affect the entire body, which is why I wish to embrace the profession of a neurologist in the future. As a dedicated student, I am always centered around the “why” of any situation whether it be in science, history, or math. I dig deeper and focus on the roots of the problem being faced…

A stem cell is a “blank” cell that can be replicated and used for many disease treatments. They serve as a built-in repair system because they naturally exist in human bodies. They can become a muscle cell or skin cell to treat certain diseases such as Cancer, Spinal Cord Injury, and Parkinson’s disease. There are two main types of Stem cells, Adult and Embryonic. Adult stem cells are cells that can replicate and transport into location that needs to be repaired and it also helps us restore our…

In the days after conception, the fertilized egg begins to form a mass of cells called a blastocyst. It is from this mass of cells that all of the human body originates from. The nuclei of all of the cells in the blastocyst contain genes that turn some cells into bone cells and others into skin cells. The cells found in the inner mass of the blastocyst are called embryonic stem cells and have the potential to differentiate into almost all other cells in the body; the pluripotency of these cells…

What are stem cells? Figure 1- Development of an Adult stem. According to Stem Cells Australia the human body contains more that 200 different kinds of specialized cells, including the muscle cells, nerve cells, fat cells and skin cells. Stem cells are resembling cells that can be divided to produce offspring cells. Specialized cells originate from stem cells, and are different from normal cells in two different ways. Stem cells are capable of renewing and making copies of them selves, as well…

Embryonic stem cells (or ES cells) are imperishable, undying. They are the undifferentiated cells which occur in the early embryo of placental mammals, and have the ability to mimic and eventually differentiate into any other cell in the mammalian anatomy. When the mouse ES cell was first identified in 1991, and its human counterpart was isolated seven years later, this immensely powerful cell became the object of many scientific discoveries, political issues, and ethical debates, topics which…

Stem Cells What are stem cells? Stem cells are cells that have the potential of become any cell in the body. There are two types of stem cells used, Adult stem cells and embryonic stem cells.1 An adult stem cell is an undifferentiated found in certain tissues in our body such as, the brain, bone marrow, blood, blood vessels, skin and liver. Adult stem cells are used to repair tissue and to replace dying of cells. For example in the bone marrow there are stem cells that create new blood cells.2…

Stem Cell Cycle Project A Stem Cell is in the class of undifferentiated cells because it is able to adapt into another cell is one part of the body is losing cells. There are two types of Stem cells, you have Adult Stem Cells and Embryonic Stem cells. Adult Stem cells or Somatic Stem Cells, exit the body after Embryonic stage, and can be found in many types of tissue. Somatic Stem Cells are found in children and also in Adults but Adult Stem cells are only found in adults. Stem cells have been…
