InВ thisВ essayВ itВ willВ beВ arguedВ thatВ embryonicВ stemВ cellsВ shouldВ notВ beВ usedВ forВ curesВ orВ researchВ becauseВ itВ isВ immoral. В Embryo'sВ areВ beingВ destroyedВ whileВ inВ theВ processВ ofВ removingВ themВ fromВ stemВ cellsВ andВ thatВ canВ damageВ humanВ life. В StemВ cellВ researchВ hasВ becomeВ veryВ controversialВ aroundВ theВ worldВ becauseВ peopleВ haveВ beenВ misinformedВ aboutВ whatВ stemВ cellВ researchВ actuallyВ is. В TheВ UnitedВ StatesВ governmentВ shouldВ notВ useВ stemВ cellВ researchВ dueВ toВ itВ beingВ unethicalВ andВ it'sВ veryВ costВ effective. В

AВ stemВ cellВ isВ anВ unВ­specializedВ cellВ ofВ aВ multiВ­cellularВ organismВ thatВ isВ ableВ toВ differentiateВ intoВ oneВ orВ moreВ specializedВ types. В StemВ cellsВ areВ commonlyВ foundВ inВ twoВ mainВ sourcesВ suchВ asВ embryo'sВ andВ AdultВ StemВ Cells. В EmbryonicВ stemВ cellsВ areВ obtainedВ fromВ aВ 4В­5В dayВ oldВ humanВ embryoВ thatВ isВ inВ theВ phaseВ " blastocyst" В duringВ theВ development. В BlastocystВ containsВ aВ layerВ ofВ outerВ cellsВ thatВ willВ eventuallyВ becomeВ theВ placentaВ andВ aВ smallВ amountВ ofВ innerВ cellsВ thatВ willВ formВ aВ fetus. В AnВ adultВ stemВ cellВ isВ anВ unВ­specializedВ cellВ thatВ isВ foundВ inВ tissuesВ orВ organs. В ItВ canВ renewВ itself, В canВ maintainВ andВ repairВ theВ tissueВ whereВ itВ wasВ found. В InducedВ pluripotentВ stemВ cellsВ isВ aВ cellВ thatВ isВ consumedВ fromВ anyВ tissueВ fromВ aВ childВ orВ anВ adultВ thatВ isВ geneticallyВ reprogrammedВ toВ beВ anВ embryonicВ stemВ cell. В ItВ hasВ theВ name, В " pluripotent" В whichВ meansВ itВ isВ capableВ toВ formВ allВ adultВ cellВ types. В InВ FigureВ 1, В itВ demonstratesВ whatВ aВ stemВ cellВ isВ andВ howВ itВ replaceВ itselfВ andВ differentiateВ intoВ manyВ cellВ types. В В

StemВ cellsВ areВ classifiedВ byВ theirВ potentialВ toВ differentiateВ otherВ varietiesВ ofВ cells. В EmbryonicВ stemВ cellsВ areВ mostlyВ pluripotentВ becauseВ theyВ haveВ theВ abilityВ toВ differentiateВ intoВ almostВ everyВ typeВ ofВ cellВ whichВ includesВ mesoderm, endoderm, ectodermВ germВ layersВ etcВ thatВ areВ formedВ inВ theВ beginningВ ofВ theВ process. В EmbryonicВ stemВ cellsВ doВ notВ onlyВ includeВ pluripotent, В butВ " totipotentВ andВ multiВ potent". В TotipotentВ isВ theВ abilityВ toВ differentiateВ intoВ allВ cellВ typesВ andВ aВ fewВ examplesВ wouldВ beВ aВ fertilizedВ eggВ orВ whenВ theВ spermВ joinsВ withВ theВ eggВ andВ formsВ aВ zygoteВ whichВ willВ multiplyВ toВ produceВ newВ cells. В MultipleВ potentВ cellsВ areВ alsoВ unВ­specializedВ cellsВ thatВ canВ differentiateВ intoВ specializedВ cellsВ withВ specificВ functions. В AnВ exampleВ ofВ aВ multipotentВ cellВ wouldВ beВ anВ adultВ stemВ cell. В

StemВ cellВ shouldВ alsoВ notВ beВ usedВ onВ researchВ becauseВ itВ isВ relatedВ toВ humanВ cloning. В " TheВ destructionВ ofВ humanВ embryosВ toВ harvestВ stemВ cellsВ isВ notВ onlyВ devoidВ ofВ theВ lightВ ofВ GodВ В В

but is also devoid of humanity” and " does not truly serve humanity”(Bush, 2001) is simply stating that God each and every person unique in his image.  It is unethical because researchers have been spending money when it is not functioning,  instead it might cause millions of people to die.  ​

" WeВ triedВ theВ sameВ approachВ toВ cloneВ monkeys, В becauseВ we'dВ beenВ interestedВ forВ biomedicalВ researchВ toВ produceВ clonedВ monkeys, В andВ itВ neverВ worked, " В heВ said. В " We'veВ beenВ workingВ forВ aВ decadeВ inВ thatВ areaВ (Mitalipov, 2013)”, В MitalipovВ isВ aВ scientistВ whoВ disagreesВ usingВ stemВ cellВ forВ researchВ sinceВ heВ hasВ beenВ workingВ onВ itВ forВ aВ decadeВ andВ stillВ hasВ notВ succeededВ andВ believesВ itВ willВ notВ cureВ anyВ diseasesВ forВ humans.

EmbryonicВ stemВ cellВ researchВ shouldВ notВ beВ usedВ forВ researchВ orВ curesВ becauseВ itВ isВ unnecessaryВ inВ severalВ waysВ andВ areВ tooВ expensive. В ThisВ shouldВ stopВ dueВ toВ allВ theВ failuresВ itВ hasВ causedВ onВ people'sВ lives. В ResearchersВ haveВ beenВ researchingВ thisВ forВ overВ aВ decadeВ andВ yetВ haveВ notВ accomplishedВ theirВ task.
