Stem cells are very unique cell and have many uses in the world today. There are many unique properties of all stem cells which are very interesting. One property of stem cells are they have four different classes of cell, which are, totipotent, multipotent, pluripotent, and unipotent. This is interesting that there are so many types of stem cells and they each have different properties. Another property of these stem cells are, they are capable of dividing and renewing themselves for long periods of time. Whenever cells can divide themselves that is called proliferation, which if they can divide for many months these cells can make millions of cells. Furthermore, stem cells are unspecialized meaning they cannot work with their neighbors to …show more content…
Stem cells have a high significance in medicine, for example, trying to find a way to replace any tissue or cells that have been damaged. To be able to replace these damaged organs it could save many lives and help many people in the long run. Also, with the right research we could be able to replicate this process and create new cells, tissue, and organs. Being able to create these new things scientists could save lives and help many people who are in …show more content…
Another challenge is how to reduce contamination and prevent contamination risks because working with stem cells can cause cancer from all the contamination. Subsequently, sometimes the cell created for the person their immune system rejects the stem cell. There can also be infection with trying to get the stem cells to replace damaged limbs and organs. Side effects are another big part of the stem cells, people who get the cells put in them can face some serious side effects that could hurt them. Another challenge would be, how to isolate and identify stem cells from the tissue that is going to be used to help these people in need.
Collecting methods by scientists of stem cells are putting the person under anesthetics and using many needles to get bone marrow, usually the pelvis. With this method the donor won't feel a thing until after a couple for days. Another type of harvest is the Peripheral Blood Stem Cell where the people take blood and use the stem cells and the rest of the blood goes into the other arm. Scientist use stem cell to restore tissue or organs which have been damaged or lost, saving many
