Research on stem cells is knowledge constantly being explored about how an organism evolves from a single cell and how cells in good condition are put in place of cells that no longer work. The outcome that is anticipated from doing this research is that if scientist can fine tune stem cells into regular cells like blood or heart muscles and put it back into the body, then possibly they may find a cure for some of the widespread diseases that exist in our world today such as diabetes, leukemia, and many more by replacing those weak cells with youthful cells. Eventually this research might lead to realistic, reasonably priced ways to get rid of many diseases through DNA engineering but is it really worth risking lives if the reality is only a possibility? There must be other ways to find a cure without extracting stem cells.
Stem cells are astonishing in the fact that they can be used to treat a profuse amount of deadly diseases including Leukemia, Diabetes, and Parkinson’s. The two main types of bodily stem cells are: embryonic stem cells and adult stem cells. In an embryo, stem cells can separate into all of the specific embryonic tissues. In adult structures, stem cells and parent cells act as a repair system for the body, mending specialized cells, but also maintaining the normal loss of important nurturing organs, such as blood, skin, or intestinal tissues.
Stem cells can evolve into any of the two hundred and twenty different cell types that exist in the human body and are beneficial as research instruments and possibly, in the future, will be used to cure a universal area of epidemics. But until then, I believe that finding other ways to cure a disease is better then risking someone’s life because researchers do not have sufficient information or practice. They are and have been called “miracle cells” ("Mibba Creative Writing") by many researchers just for this reason. They have no clear-cut job in the human body, so stem cells can be altered into any type of cell. Generally this is good because taking them out should not harm. However, if not done correctly the body could react in a manner that would leave the human lifeless. Is it really worth the risk when there are other ways to cure diseases given all the technology at our disposal? Stem cells can be injected into an ill person’s body for treatment, and can possibly lead to a cure. But, is possibly the answer people want?
Stem cells can also be used to test new drugs. Other kinds of cells are already being used in this manner so why do people feel the need to extract stem cells? Cancer cells, for example, are used to test possible anti-tumor medication. The accessible amount of stem cells would allow drug testing to consist in a wider range of cell types. However, to examine drugs productively, the environments must be the same when comparing different drugs. Therefore, scientists will have to be capable of accurately regulating the contrast of stem cells into distinct cell types on which drugs will be tried. Currently, duplicating the exact conditions for each drug is subject to error.
Adult stem cell research, as with embryonic stem cells, also presents disadvantages. Although these cells can be accessed from the bone marrow, there are in limited supply. Only so many cells can be gathered from one individual, which forces scientists to have to make tough choices with what is available and leaves no room for misteps. “Adult stem cells also do not have a long storage life,” ("Cord Blood Cells") meaning they may not survive as long as their embryonic copy. Yet another disadvantage is that the procedure in order to attain these cells is extremely difficult. These cells do not have the capability of being reprogrammed to transform into any cell type due to its inflexible structure. Lastly, there are still many unknowns that come with adult stem cells. They may have defects and the disease that is...
