Dearminister of health, in this letter I’m going to explain why using inducedpluripotent stem cells is good, but also why induced pluripotent stem cellsshould not be used. In this letter I’m also going to explain what they are, howthey can be used and why they are used. This letter is going to be facts, butalso about my view and what I think about stem cells.
Whatis a stem cell? A stem cell is a cell that has no specific job. This means thatthese cells have the potential to become any cell in the body. For example, bloodcells or skin cells. These cells have the potential to become even morespecialised in one specific area of the body. This means that these types ofcells are the foundation of our body. Stem cells have two mayor properties. Thefirst one is that they have the ability to self-renew. This means that they canmake exact copies of themselves.
The second function is that they candifferentiate. This means that they transform into specific cells which Italked about earlier in the letter.Thereare three types of stem cells, with all different properties. The first one istissue-specific stem cell. These cells can also be called adult or somatic stemcells.
These cells differentiate from the other types of stem cells, becausethese are more specialised than other types. These cells are located in onespecific tissue. Then when other cells die, these types of stem cells have toreplace the dead cell. These cells are found deep in a tissue, for example, thebone marrow in our body. The second type of stem cells is embryonic stem cells.These cells are also called pluripotent stem cells.
Pluripotent means that theyhave the ability to become many different types of cells as long as they arespecified to do so. These stem cells differ from tissue specific stem cellsbecause the embryonic stem cell have the potential to become any type of cell,but the tissue specific cells can only become more specified within a tissue.Embryonic cells are the first cells in a human body to be made. It happens whenan egg is fertilized. As the cells multiplies a blastocyst is formed.
This is aball of approximately 150-.200 cells. The last type is called inducedpluripotent stem cell (IPS). These stem cells are tissue-specific stem cellsthat have been reprogramed by scientists to become embryonic cells. These cellsare needed when many cells have died and there are not enough stem cells toreplace the dead cells. They do this by “making” embryonic cells and theexposing them to an environment where the stem cell can become a specific cell.For example, skin cell or liver cell There is both good andbad things of using IPS cell. The question is if there are more good thingsthan bad, and if that is the case should we use IPS cells more often.
Let’sfirst take a look at the pros in using IPS cells. If we could use IPS cells itwould give us a good insight in our body. IPS cells can be used to maketreatments against different diseases. By using IPS doctor can make morepersonalised treatments. For example, Parkinson’sDisease, Alzheimer’s Disease, Heart Diseases, Stroke and Diabetes (Type 1), SpinalCord Injuries, Replace or Repair Damaged Organs, and stem cells may play amajor role in cancer. These are all diseases that could help be cured with IPScells, but what could be the negative sides by using IPS cells? The negativesides are that; some people argue that this research could in the future leadto “bad” knowledge.
“Bad knowledge” means that people in the future will knowhow to clone and that would not make people feel safe, because people couldmake armies out of cloned people. Another thing is that people say that youshould not mess with human life or that we should not try to play God. There aremore ethical issues, but they are all have the same point and it is that it isnot really ethical to take embryonic cells from a fetus.Ithink that stem cell research is important.
The important part about IPS cellsare that they can cure a lot of diseases and that is what counts. I can agreeon that it would not be very nice if scientists new how to clone, but thequestion is if it is ever going to go that far. I think that the biggestproblem right now with stem cells is that it is only a few people that can getthis type of medical help since this method is kind of new. ConclusionInducedpluripotent stem cell is one of the three types of stem cell, which is a cellthat has no specific job. IPS cells being one of the most talked about area inscience, are cells that are embryonic cells taken from fetuses ortissue-specific/ adult cells being reprogramed into embryonic cells.
Thequestion is, should people be able to do this? I think that scientist should dothis, because I think that the positive outweigh the negative things aboutusing IPS cells. The good things are that they can help curing some diseasesand the bad stuff that some people are questioning if it is ethical enough. So,my conclusion is that I think that it is much more worth to save some one’slife that thinking about if this method is ethical or not.
