Detailed explanation-1: -Stem cells are unspecialized cells of the human body. They are able to differentiate into any cell of an organism and have the ability of self-renewal. Stem cells exist both in embryos and adult cells.

Detailed explanation-2: -Pluripotent stem cells have the ability to differentiate into all of the cells of the adult body. Adult stem cells are found in a tissue or organ and can differentiate to yield the specialized cell types of that tissue or organ.

Detailed explanation-3: -Answer. Stem cells are the cells that have an ability to become various types of cells. They are present both during embryonic development (embryonic stem cells) and in the adult body (adult stem cells).

Detailed explanation-4: -Stem cells exist both in embryos and adult cells. There are several steps of specialization. Developmental potency is reduced with each step, which means that a unipotent stem cell is not able to differentiate into as many types of cells as a pluripotent one.

Detailed explanation-5: -Oligopotent: These can differentiate into a few different cell types. Adult lymphoid or myeloid stem cells can do this. Unipotent: These can only produce cells of one kind, which is their own type.
