Stem Cell
A stem cell is an immature cell that has the potential to differentiate into various specialized cell types. It is capable of self-renewal and can give rise to different tissues and organs.
For example, in humans, embryonic stem cells are found in early-stage embryos and have the ability to develop into any type of cell in the body. Adult stem cells, on the other hand, are present in specific tissues and can only differentiate into limited cell types.
