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

Stem Cells What, How and Why?Stem cells are unceasingly valuable when considering theirpotential applications in the medical profession. Whilecurrent legislative restrictions bind halted the development ofnew ? shank cell lines? to any execution or company that receivesany form of disposalal grants, there is no question that themedical profession is standing at the brink of a new era oftechnological advancements in healthcare and look.Stem cells are valuable due to the fact that they are?non-designated,? (have no specific entirelyy appoint task in thebody, i.e. liver cells, brain cells, skin cells, etc.) and theyalso have the ability to divide indefinitely. Thus,theoretically hold cells could replace any discredited or lostspecifically designated cells within the body. However, thisis just a draft mention of the potential applications of stemcell research, which will be discussed at a later point in thises assert.Stem cells are reason into three genres based upontheir po tential developmental capability, total to limited.(NIH PRIMER http//www.nih.gov/ give-and-take/stemcell/primer.htm)totipotent stem cells are stem cells whose potential istotal, olibanum 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 difficult to behave by and hardly occurin authentic places at certain developmental times.Pluripotent stem cells are stem cells in which theirpotential is queen-size but not total as in Totipotent stem cells.These cells lead to the development of some(prenominal) cells, but cannotderive certain types of foetal cells necessary for thedevelopment of a fetus as do Totipotent stem cells. Thesecells undergo further assigment into cells that are designed toder ive specifically assigned cells. Pluripotent stem cells aresomewhat easier to come by relatively speaking to totipotentstem cells. The final genre of stem cells is that of multipotent stemcells. These cells are more 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 knowledge 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 offer leave. It seems asthough the States is one of the last overly conservativestrongholds leftfield 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 regard 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 do itillegal to write about what I desired, I would do any(prenominal)necessary to allow myself to follow my passion. Moving across that big pocket billiards we call the Pacific Ocean would bea small set 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.
