Cellular differentiation

m cells are unique because during early life they have the ability to develop into a variety of different cell types. Essentially, stem cells are the blank slate necessary for the creation of specialized cells. These specialized cells include muscle cells, brain cells or red blood cells, etc. Adult Stem Cells and Embryonic Stem Cells – The Difference Adult Stem Cells Adult stem cells can continue to self-renew or divide, indefinitely. This enables them to produce a variety of cell types:…

Embryonic stem cells are very controversial in the scientific community and as well as the medical community for many reasons. “Stem cells are cells that can be any cell that the human body needs to be”,(Rowlery,usnews.com). For example, a stem cell can be a skin cell, a liver cell and or a bone cell. The reason why embryonic stem cells are extremely controversies is because the cells come from human embryos. To obtain theses types of cells a mother need to have an abortion, and doctors and…

All great leaps in our society have first met with some moral conflict. Scientists today are facing the use of embryonic stems cells and if their use takes away a human life. It has been proven this small group of specialized cells can treat many diseases that we have battled for some time. In the case of the embryonic stem cell research, it is almost impossible to respect both moral principles of respecting the value of a human life and to prevent or alleviate suffering. These two principles…

Ethics and Stem Cell Research The University of Maryland Medical Center defines a stem cell as a generic cell that can make exact copies of itself indefinitely (UMMC,2016). Stem cells are known for their ability to transform themselves into various tissues such as heart muscle, brain tissue, liver tissue and kidney tissues. There are two types of stem cells; the first one is known as an Embryonic stem cells, these are removed from fetuses that have been aborted or from…

The operations of cloning have brought out an abundance of fundamental milestones laying concrete on rearing onto the likelihood for an acceptance of therapeutic cloning. There exists a manifold quantity for the, “applications of this technology in nonhuman animal models will undoubtedly contribute in a major way to vaccine development and the unraveling of teratological and genetic problems in human development as well as impacting wildlife conservation efforts” (Wolf, Meng, Ely, & Stouffer,…

Figure 1: Shows the gene expression changes found in Arabidopsis after the insertion of the IRX1, IRX3, and IRX5 mutants(Brown). 1A shows the principal component data collected from the targeted areas of the plant(Brown). 1B shows a comparison of gene expression of the base and tip of the stem and the change of level(Brown). 1C shows the slope of genes most likely to be related to IRX3(Brown). From Figure 1B, it is shown through analysis that there are several hundred genes that show an increase…

Catarina Garcia Engbrock English DC 9 March 2018 Mini Research Paper An example of modern science/technology that I think oversteps moral boundaries and has yielded unwanted consequences is cloning for stem cell research. In Mary Shelley’s Frankenstein, Victor Frankenstein creates life, which could have it’s benefits, but he did not think of the problems and unwanted consequences that could result from it. Although there are benefits to cloning there are also unwanted effects and unnecessary…

The key to the future is in the cells. Scientists have unlocked the cell in stem cell investigations. On average, 30 people die daily because they can’t get a transplant and over 120,000 people are on the transplant list (Greely). This makes stem cell potentially life-saving for thousands of people. Scientists can now help save lives and protect human life. It may be hard to distinguish the difference between stem cells and other cells, but some of the major differences between stem cells and…

Robotic Surgeries Vs Traditional Surgeries: An Rhetorical Analysis The topic of robotic surgeries compared to open surgeries and their costs has been a debate since 1983 when the first robotic-assisted surgery was introduced (Background). This debate is brought up and analyzed in Gabriel Barbash, M.D. and Sherry Glied Ph.D article entitled “New Technology and Health Care Costs –The Case of Robot-Assisted Surgery,” and was published in the highly renowned New England Journal of Medicine. This…

Metamorphosis is a biological process by which an animal physically develops after birth or hatching, involving a conspicuous and relatively abrupt change in the animal's body structure through cell growth and differentiation. “Some insects, fishes, amphibians, mollusks, crustaceans, cnidarians, echinoderms and tunicates undergo metamorphosis, which is usually accompanied by a change of habitat or behavior”. (http://en.wikipedia.org/wiki). But this change has been incorporated to human’s life…
