Stem cells show the potential to be able to heal many types of injuries and degenerative diseases. Though stem cell therapies are questionable in their effectiveness, New York Yankees pitcher Bartolo Colon opted to have a treatment done in the Dominican Republic after having persistent arm troubles that prevented him from completing a single full season from 2005 to 2012, and even forced him to sit out for the full season in 2010. Steve Sternberg, a regular correspondent of USA Today, reported…

The process of obtaining embryonic stem cells is one that is quite problematic. It is not as easy as mining in a mine or collecting water from a lake. It takes a delicate process to extract these important cells. Embryonic stem cells come from human embryos. These embryos have an abundance of stem cells that can be used to help cure diseases and illnesses. One drawback though from taking these cells though is the life of potential human. When scientists take embryonic stem cells from embryos, a…

Stem cell research Stem cell research is truly a remarkable and celebrated discovery for the science and medical field. The cells are available in all shapes or sizes, and they also have the capabilities of being genetically altered to fit the needs of the experiment or study. This topic is not a popular topic for society. A lot of people claim these cell studies to be immoral, and unethical. Society claims that it is similar to playing “GOD”. However, it is in the best interest of society,…

How exciting would it be to be able to help millions of people who are suffering by separating just one line of cells? That could be possible with stem cell research. Amazing new studies are using human cells, more specifically the stem cell, to help many people. The stem cell has the ability to multiply itself repeatedly, which makes them very important to regenerative medicine ("Stem Cell"). Feeling encouraged by the results, many say this could be a chance to begin the end of illnesses…

Are Stem Cells Worth The Cost? Introduction Stem Cells have a lot of potentials to cure/heal the human body, but is it worth the cost? Embryonic stem cells have the potential to transform medicine. Scientist and doctors believe they could potentially treat a myriad of human conditions and diseases, such as spinal cord injury, type 1 diabetes, neurodegenerative diseases and many others. However, there are many issues and barriers to fulfilling this potential. Helping people walk again sounds like…

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…

Planarian Regeneration Mechanism Subject to Different Cut-Types Introduction: Planarian are flatworms which are common in aqueous regions all across the world. They are often used as models in the study of biomedical and biotech sciences, due to their ability to regenerate. Planarian have such advanced regenerative properties that over 1/279th of the animal can completely regenerate (Handberg et al., 2007). They have powerful regenerative capabilities because they have an abundance of…

I personally believe that embryonic stem cell research is an important investment for the future. Stem cells are cells that are able to develop into different types of cells. Stems cells have the potential to be used to cure many diseases. There are also other uses for stem cells like organ repairs. Even though they would be so beneficial, there is an ethical debate. I believe that it is ethical and that it is something that should be done. There is a huge debate over the ethics of stem cell…

Many people disagree with stem cell research. Their biggest reason for this position is the embryonic stem cells would come from aborted fetuses. Some people feel that abortion is unethical and that stem cells obtained by breaking open and killing the embryo is morally wrong. They see it as murder and feel that we are a nation that places too little value on human life. They believe this goes against what they are taught through their religion and that destroying an embryo for the stem cells in…

Background and need: During embryo development many factors can determine the future outcome and growth of developing embryo. These factors, whether genetic or environmental, will influence the cells within the embryo and could result in a lasting developmental abnormality, such as unwanted apoptosis. Ethanol, a known teratogen, is one such unorthodox environmental factor that if present will have an effect on the embryo’s development; namely defects in the cardiovascular system, structural…
