The purpose of this experiment was to observe how calf serum affected cell proliferation. It was hypothesized that various concentrations of Fetal Bovine Serum (FBS) would provide nutrients for non-transformed cells, and therefore affect their growth, but have no effect on the transformed cells. It was also hypothesized that the protein concentrations will increase for the non-transformed cells upon addition of the calf serum and FGF, but not affect the transformed cells since they are not dependent on growth factors. After analyzing the results, it can be concluded that increasing FBS concentrations does in fact increase non-transformed cell density. Transformed cells are unaffected by this concentration as is proven by the results since the cell densities are roughly the same at the differing concentrations of FBS (0.5%, 2%, and 10%). Furthermore, since the ERK1/2 factor is increased in the non-transformed cells, the cell density will also increase. Introduction: An increase in the population of cells is referred to as cell growth. This growth is monitored by regulation points after each stage of the cell cycle. Transformed cells differ from normal cells because they have an infinite lifespan. Transformed cells arise due to an alteration in the cell cycle. This alteration is passed on similarly to how traits are passed on in evolution. Since transformed cells are stronger than normal cells, they are ‘more fit’ for their environment. However, that does not necessarily mean

Our genes regulate cell growth and cancer occurs due to abnormal changes in these genes. Genes are in each cell's nucleus and control the cells growth in relation to our genetic make up. The cells grow and replace themselves in a natural
These cells can grow into many things such as organs, tissues, muscles, or blood. These cells are able to renew themselves through cell division. One of the most unique aspects to these cells are they are able to replenish and repair themselves as long as the person is alive. This can be seen most commonly in red cells of the bone marrow. These cells are continuously repairing and replacing damaged and old cells. Because of stem cells unique ability to renew themselves into new cells, scientist have shown great interest in these cells. Stem cells that are being studied most by scientist are embryotic stem cells, adult stem cells, and induced pluripotent stem
Around the world, millions of scientists conduct their studies by testing their research on animals. Many people believe that experimenting on animals is crucial to the advancement of medical discoveries. Studies show however, that animal experimentation is brutal and unnecessary. There are alternatives though: “replacement, reduction, and refinement” (Howard 2).
Are division one college athletes are getting ripped off because they do not get payed for playing their sport? Many say that these athletes are getting payed enough through their scholarships they are awarded for going to that school. They should get some type of extra payment for how much they spend on their sport and then their studies as well. Just imagine having to wake up every day and going to classes for 6-8 hours then having to go to practices or games right after that. Then having to do that all over again the very next day and for the rest of the week. That’s the weekly schedule for the average Division One college athlete. After having to do all of this, they still get nothing extra for having to balance their schedule so they can get enough sleep, still do their homework, and getting to practices on time daily.
Stem cells are cells that have the potential to become almost any cell in the human body, during the early developments of life. Stem cells have the possibility to generate all of tissues within a human as well. Each stem cell can either stay a stem cell or become a more specialized cell. The stem cells that are unspecialized are capable of renewing themselves or possibly being induced to become organ specific cells or tissue cells with special functions. Most stem cells have a constant supply to replace other cells that are injured, diseased, or even aged.
Scientists are interested in stem cells for their ability to become any type of cell in the body, a process called differentiation. Theoretically, this allows for limitless possibilities in disease
Animal Farm: Dangers of an Uneducated Society Animal Farm, written by George Orwell, is a short novel that uses fable to bring awareness to the dire consequences of an uneducated society. The novel parallels the pigs to the humans, both of whom end up being consumed by greed to the point they are willing to oppress others in order to maintain their positions of power. The series of events in the novel illustrate the extreme danger of an uneducated society; if not for the farm animals’ lack of intelligence, the animals’ society would not have been able to fall to ruin as it did – it was the crowd’s inability to think for themselves that ultimately allowed corruption to take root and seize control in the community. Thus, it is shown that an

Cells share many common features but have adapted over billions of years in a wide array of environments, to provide a variety of functional roles.
Stem cells are cells that have the capabilities to develop into many different types of cells in the body. Serving as a type of repair system for the body, they can theoretically divide without limit to take over for other cells for
