Stem Cell DNA Repair

Stem cells are defined as cells that can differentiate into specialized cells. The stem cells are initially formed in the inner cell mass of blastocysts in embryonic development that are pluripotent and can differentiate into all the cell types of the body. Stem cells have the unique property of symmetric and asymmetric division. Symmetric division is when the stem cells give rise to two daughter cells of the same kind, and in most cases, divide to form two stem cells that maintain their pluripotency. Asymmetric divisions give rise to two different cells. Asymmetric division in pluripotent stem cells results in the stem cell giving rise to two daughter cells with different states of differentiation. One of the cells is a stem cell and the other ...
