Developmental biology

Planaria are triploblastic acoelmate flatworms that inahabit marine and terrestrial environments and belong to the phylum Platyhelminthes. Though they are relatively complex creatures, as they possess an extremely branched gastrovascular cavity, a brain, hermaphroditic reproductive abilities, Planaria are best known for their regenerative capabilities (Rink, 2012). This is not a recent discovery, however. Peter Simon Pallas first described this regeneration 230 years ago in 1766, and Dalyell…

professor of pathology at Wake Forest University School of Medicine, writes, “The fact that Jesus became a human being at the moment of conception reinforces that all human stages have inherent value” (qtd. in Clemmitt). Although they are at early developmental stages compared to other human life, they should still receive the respect and honor that adult human beings receive (George and Lee 66). There is no reason that embryos should be massacred in embryonic stem cell research, as they harness…

One of the most debated topics in science is the use embryonic stem cells in scientific research. The ethical debate surrounding embryonic stem cell research comes down to two core values that we want to uphold: the alleviation of human suffering and preserving the inherent value of human life. Embryonic stem cell research is such a tricky topic because it requires us to choose between these two core values. We cannot uphold both values because the alleviation of suffering in this case is…

Embryonic Stem Cell Research Argumentative Paper If you were diagnosed with an incurable disease, would you do everything in your power to save yourself? Would you want to have access to a potentially life-saving treatment? A paralyzed man after a terrible car accident, regained the use of his arms after an experimental clinical study using stem cells (Aldrich). A (now), 5 year old girl suffering with SCID, was completely cured. These successes are just two, that represent the capability of…

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…
