Detailed explanation-1: -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.

Detailed explanation-2: -In naive embryonic stem cells not all genes are active, as previously thought. Rather these genes are “paused”, ready for action if needed. In naive embryonic stem cells not all genes are active, as previously thought.

Detailed explanation-3: -There are several main categories: the “pluripotent” stem cells (embryonic stem cells and induced pluripotent stem cells) and nonembryonic or somatic stem cells (commonly called “adult” stem cells). Pluripotent stem cells have the ability to differentiate into all of the cells of the adult body.

Detailed explanation-4: -Cell differentiation is known as a process in which cells become specialized. Pluripotency means the potential to become any cell type and is a potential observed in stem or progenitor cells at the beginning of the differentiation process.

Detailed explanation-5: -Hematopoietic stem cells (HSCs) are the stem cellsthat give rise to other blood cells. This process is called haematopoiesis.
