Stem Cell Definition:
A cell that has not gone through differentiation
A stem cell is a cell that has not gone through the process of cell differentiation. In other words, it is undifferentiated.
This makes stem cells very useful because they still have the option to become any type of specialized cells such as muscle cells, epithelial cells, nervous cells…etc.
Knowing this about stem cells, it is not hard to understand why they are important in medical research. For example, if a person has a damaged liver, we repair the damage by:
- Gathering and growing his stem cells.
- Differentiating these stem cells into liver cells
- Then, use these liver cells to replace the damaged parts of the liver.
