Explanation:
Detailed explanation-1: -Pluripotent stem cells are undifferentiated; they do not have any tissue-specific characteristics (such as morphology or gene expression pattern) that allow them to perform specialized functions.
Detailed explanation-2: -Finally, we have the unipotent stem cells, which are the least potent and most limited type of stem cell. An example of this stem cell type are muscle stem cells. While muscle stem cells can self-renew and differentiate, they can only do so into a single cell type.
Detailed explanation-3: -Stem cells are special human cells that are able to develop into many different cell types. This can range from muscle cells to brain cells. In some cases, they can also fix damaged tissues.
