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: -Stem cells are unspecialized cells that have not yet “decided” what type of adult cell they will be. They can self-renew and make two new stem cell. They can differentiate to make multiple types of cells.

Detailed explanation-3: -Embryonic stem cells are derived from embryos that develop from eggs that have been fertilized in vitro. As long as the embryonic stem cells in culture are grown under appropriate conditions, they can remain undifferentiated (unspecialized).

Detailed explanation-4: -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-5: -Stem cell differentiation involves the changing of a cell to a more specialized cell type, involving a switch from proliferation to specialization. This involves a succession of alterations in cell morphology, membrane potential, metabolic activity and responsiveness to certain signals.
