Although, stem cells have the attention to transform the entire medical field and change many lives. Thesis Statement: Today am going to discuss what stem cells are, how they are used, and the benefits and controversy that surround the research. Transition Statement: First I will be informing you of what a stem cell actually is. Main Point One: By definition, a stem cell is “an undifferentiated cell of multicultural organism that is capable of giving rise to indefinitely more cells of the same type, and from which certain other kinds of cells arise by differentiation. Basically, they are cells that are capable of reproducing themselves through cell division. Mound in research from a book called “Stem Cells” by the Greengages Press, that these cells are found mostly in human embryos that are created for reproductive purposes through IV (in vitro fertilization) more commonly know as artificial insemination. Transition Sentence: Next I will be discussing how we may use stem cells to benefit our lives. Stem cells are very important for living organisms for many reasons.
In the 3-5 day old embryo state, called a blastoffs, the inner stem cells help to form many cell types and organs such as heart, lungs, skin, sperm , eggs and other important tissues. In some cases in adult tissues, bone marrow, muscles, and brain tissue. We can use this technology to regenerate tissues and other organs needed for human bodies that have been injured. Stem cells are also capable of curing certain diseases such as cardiovascular disease. Aka heart disease) Last I will be discussing the controversy that surrounds stem cell research. Main point Three: until recently the only way to obtain stem cells was to remove the in near cell mass of an embryo. This created a lot of controversy concerning questions such as, “Does life begin at fertilization, in the womb, or birth? However, it is somewhat unknown that laws have actually been passed to prohibit the creation of stem cell research itself. Scientists instead receive “leftover” embryos from fertility.
In 2006 researchers made a breakthrough by identifying conditions that would allow some specialized adult cells to be “reprogrammed” genetically to assume a stem cell-like state. These are called induced plenteous stem cells or epic’s. Conclusion: In all it is evident that stem cell research is indeed very complicated, and because of this a lot of people have a lot of different opinions about the research that goes along with it. Oneself think that stem cell research should not be taken lightly, it has the ability to further the medical field and take it to the next level.
