LIFE SCIENCE

Detailed explanation-1: -Estimates vary on the number of blood stem cells, with a recent paper reporting a range of 50, 000-200, 000 in a healthy adult person. Secondly, in terms of cell identity, there are also gray areas where we aren’t always sure whether a given cell is a stem cell or some other similar cell type like a progenitor cell.

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. You may also see the term “somatic stem cell” used to refer to adult stem cells.

Detailed explanation-3: -A person’s body contains stem cells throughout their life. The body can use these stem cells whenever it needs them. Also called tissue-specific or somatic stem cells, adult stem cells exist throughout the body from the time an embryo develops.
