They are types of cells that can differentiate into cells with highly specialized functions, making up different types of tissues in the body. In practical terms, we can say that stem cells are cells that have the potential to rebuild damaged tissues and thus help in the treatment of diseases such as cancer, Parkinson's disease, Alzheimer's disease, and degenerative and heart diseases.

These cells have two distinct characteristics:

• they can reproduce, duplicating themselves and generating two cells with identical characteristics

• they can differentiate, that is, transform into various other cells of their respective tissues and organs.
