Even though some philosophers think human embryos are like stem cells due to the lack of rational nature, they have the full potential and ability to have a rational nature. If human embryos don't have a rational nature neither do stem cells. If one decides to destroy a human embryo, then its potential is interrupted. Compared to stem cells, human embryos have a probability to become an adult which gives it a chance to reason and make choices for itself in the future. With this argument, human…

A cell is a very basic structural and functional unit of life. A human body is considered multicellular because the body consists of trillions of cells. Cells have many different functions throughout the body, and they ‘stem’ from simpler cells that do not yet have a specific function. These cells are known as stem cells. This basically means these cells do not have a specific job in body yet, but have the potential to become any cell in the body. Stem Cell research has been around for decades,…

of stem cell research, it has caused quite a controversy for many people. It has many different aspects that are sometimes not made known to people. Society often times feel very strongly about their own opinions on the topic and are not always willing to listen to other views or learn anything new. Many think the process isn’t ethical but some believe that the research taking place is necessary for the betterment of medicine. Today there are many different views and outlooks on stem cell…

opinion on stem cell research has drastically changed from when the controversy first got major media coverage in 2001. According to a poll posted to isidewith.com, 73 percent of Americans agree the federal government should fund stem cell research, while 27 percent think the contrary. But why has public perception taken a complete and utter turnaround from years ago? One may argue, positives of stem cells outweigh the negatives. Today, we have a better understanding of what these cells are…

When multi-cellular organisms develop, cells must differentiate to form specialised cells, which have a diverse range of functions, these then give the organism the necessary assistance to survive and eventually live. A stem cell is a cell which is undifferentiated and not yet specialised, although it has to capability to form or configure itself into any other type of cell. Fertilised embryos are called zygotes which then produce pluripotent embryonic stem cells, a prerequisite to the survival…

Stem Cells Stem Cells are an unspecialized type of cell that can change into many different types of cells in early stages of life. In certain tissues these cells act as a type of internal repair system, which divide with almost no limit and repair and replace old or replenish other cells if the person or animal is alive. When stem cells divide they have the chance to become a different type of cell with a more specialized function or stay a stem cell¹. Stem cells are important because they can…

EMBRYONIC STEM CELLS What are stem cells? Stem cells are the body's raw materials. Cells from which all other cells with specialized functions are generated they are also called daughter cells. They either become new stem cells or become specialized cells with a more specific function, such as blood cells, brain cells, heart muscle or bone. Embryonic stem cells come from embryos that are three to five days old. At this stage, an embryo is called a blastocyst and has about 150 cells. They can…

kill white blood cells and weaken the immune system are not as life threatening as they used to be. While this fantasy world isn’t a reality, it could be. Enter the stem cell: An amazing feat of the human body. These cells can become any cell in the human body, from skin tissue to brain cells. Unfortunately, the cells can only become any cell during development - in the womb, that is.Adults have stem cells too, but their functions are vastly limited compared to embryonic stem cells. While there…

Stem cells are characterized by the ability to replicate themselves limitlessly. After being created, these identical copies can remain undifferentiated for a long period of time. When receiving specific signals from internal and external environments, they transform themselves to a particular type of cell in the body with specialized functions and features. Therefore, they act as an essential system for tissue repair and growth (National Institutes of Health, 2009). Based on their origins, stem…

of Stem Cells. The two main types of cells cultured are called Embryonic Stem Cells and Adult Stem Cells (“Basics”). Embryonic Stem Cells are formed by a newly fertilized egg ready to begin its first division process. This type of stem cells can be broken down into two different categories; In Vitro Fertilization which is taken from donated human blastocyts and Alter Nuclear Transfer which involves the slipping and separation of the nucleus of the donated egg (Jurkowski). Adult Stem Cells are…
