Stem Cells: What How and Why? Essay -- essays research papers

Stem Cells What, How and Why?Stem cells atomic number 18 infinitely worthful when considering theirpotential applications in the medical profession. While menstruation legislative restrictions have halted the development ofnew ? topic cell lines? to any(prenominal) agency or company that receivesany form of governmental grants, there is no question that themedical profession is standing at the brink of a new era oftechnological advancements in healthcare and enquiry.Stem cells are valuable due to the fact that they are?non-designated,? (have no specifically assigned task in thebody, i.e. liver cells, brain cells, skin cells, etc.) and theyalso have the ability to select indefinitely. Thus,theoretically bowing cells could replace any damaged or lostspecifically designated cells within the body. However, thisis just a brief mention of the potential applications of stemcell research, which will be discussed at a later point in thisessay.Stem cells are categorized into three genres based upontheir potential developmental capability, total to limited.(NIH PRIMER http//www.nih.gov/news/stemcell/primer.htm)Totipotent stem cells are stem cells whose potential istotal, thus totipotent. Totipotent stem cells are derived fromembryonic tissue and fertilized ovarian eggs. This type of stem cell is of particular importance toresearchers due to its ability to ?specialize intoextraembryonic membranes and tissues, the embryo, and allpostembryonic tissues and organs? (NIH Primer). However thesetype of cells are extremely tall(prenominal) to come by and only occurin certain places at certain developmental times.Pluripotent stem cells are stem cells in which theirpotential is large-scale but not total as in Totipotent stem cells.These cells lead to the development of many cells, but tailnotderive certain types of fetal cells requirement for thedevelopment of a fetus as do Totipotent stem cells. Thesecells undergo further assigment into cells that are designed toderive spe cifically assigned cells. Pluripotent stem cells aresomewhat easier to come by comparatively speaking to totipotentstem cells. The final genre of stem cells is that of multipotent stemcells. These cells are more than specialized than the other twocategories and thus are more restricted in their capability.Multipotent stem cells are derived from pluripotent stemcells. While pluripotent stem cells are least in theirpo... ...if a republicanpresident is elected following Bush. Some might say theserestrictions are necessary as technology and fellowship expand.However, by allowing the government to limit was scientist canand can?t do we?re only doing one thing. Making the mostbrilliant minds our country has to brook leave. It seems asthough America is one of the last overly conservativestrongholds left in the modern world. If we allow ourgovernment to restrict what scientist can research in theUnited States, the scientist will simply move somewhere wherethe research isn?t illegal. I r egard science as a passion. Ican say with absolute certainty it is not my passion, howeverto many who make it their career choice, it is. I offer youthis example. My passion is writing, if the government made itillegal to keep about what I desired, I would do whatevernecessary to allow myself to follow my passion. Moving across that big pond we call the Pacific maritime would bea small price to pay to follow my passion and practice itfreely. It should be noted that by restricting research ofnearly any kind (yes I do have some morals) would simply resultin the loss of America?s greatest thinkers.
