Abstract By understanding how components within certain cells confer their ability to regenerate or antagonize cellular differentiation into specific cell types‚ we can change these components to make our cells have regenerative properties. To understand this‚ we examine cells of the germline‚ called germ cells. These "parent" cells of sperm and egg cells have the ability to become any cell type of each subsequent generation‚ and are thereby totipotent. This totipotency essentially makes germ cells
