Stem cells are cells of the body (somatic cells) which can divide and become differentiated. When an organism grows, stem cells specialize, and take specific functions. For instance, mature tissues like skin, muscle, blood, bone, liver, and nerves, all have different types of cells.

Stem cells are found in every moment of the growth in life. It can divide indefinitely and can differentiate into almost any cell type in the body

Stem cells can be guided into becoming specific cells that can be used to regenerate and repair diseased or damaged tissues in people. Stem cells may have the potential to be grown to become new tissue for use in transplant and regenerative medicine.
