PATHOLOGY

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. There are several steps of specialization.

Detailed explanation-2: -Adult Stem Cells (ASCs): ASCs are undifferentiated cells found living within specific differentiated tissues in our bodies that can renew themselves or generate new cells that can replenish dead or damaged tissue.

Detailed explanation-3: -Stem cells are characterized by two unique properties with respect to specialized cells; in vivo, they are able to divide by maintaining their stemness; this process is termed self-renewal. Additionally, all stem cells retain the capacity to progressively differentiate into mature cell types.

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: -Embryonic stem cells. These are pluripotent (ploo-RIP-uh-tunt) stem cells, meaning they can divide into more stem cells or can become any type of cell in the body. This versatility allows embryonic stem cells to be used to regenerate or repair diseased tissue and organs.
