Detailed explanation-1: -Pluripotent stem cells are undifferentiated; they do not have any tissue-specific characteristics (such as morphology or gene expression pattern) that allow them to perform specialized functions.

Detailed explanation-2: -Stem cells are unspecialized cells that can self-renew indefinitely and that can also differentiate into more mature cells with specialized functions.

Detailed explanation-3: -Adult stem cells, also called somatic stem cells, are undifferentiated cells that are found in many different tissues throughout the body of nearly all organisms, including humans.

Detailed explanation-4: -Differentiation is the process by which unspecialized cells become specialized to carry out distinct functions. A stem cell is an unspecialized cell that can divide without limit as needed and can, under specific conditions, differentiate into specialized cells.

Detailed explanation-5: -Stem cells are undifferentiated or “blank” cells that have not yet fully specialized. Under proper conditions, stem cells begin to develop into specialized tissues and organs. Additionally, stem cells can self-renew, that is they can divide and give rise to more stem cells.
