Abstract: Adult stem cells are the source of continuous supply of differentiated cells. Upon stem cell division, its daughters either self-renewal or differentiate, a balance of which is critical to tissue homeostasis. To maintain this critical balance, many stem cells have a potential to divide asymmetrically, giving rise to one stem cell and one differentiating cell.
Drosophila male germ line stem cells (GSCs) divide always asymmetrically, producing one self-renewed stem cell and one differentiating cell. This asymmetric stem cell division is tightly controlled via stereotypical positioning of mother and daughter centrosomes, leading to oriented spindle with respect to the stem cell niche and thus asymmetric stem cell division.
I will discuss the mechanisms of asymmetric stem cell division, how asymmetric stem cell divisions are coordinated among multiple stem cell populations and describe about newly discovered asymmetries during the stem cell division.
