Asymmetric centrosome behavior and the mechanisms of stem cell division
The ability of dividing cells to produce daughters with different fates is an important developmental mechanism conserved from bacteria to fungi, plants, and metazoan animals. Asymmetric outcomes of a cell division can be specified by two general mechanisms: asymmetric segregation of intrinsic fate determinants or asymmetric placement of daughter cells into microenvironments that provide extrin...
متن کاملCentrosome-dependent asymmetric inheritance of the midbody ring in Drosophila germline stem cell division
Many stem cells, including Drosophila germline stem cells (GSCs), divide asymmetrically, producing one stem cell and one differentiating daughter. Cytokinesis is often asymmetric, in that only one daughter cell inherits the midbody ring (MR) upon completion of abscission even in apparently symmetrically dividing cells. However, whether the asymmetry in cytokinesis correlates with cell fate or h...
متن کاملRegulation of asymmetric stem cell division: spindle orientation and the centrosome.
Asymmetric stem cell division, as a means of maintaining adequate numbers of stem cells, has attracted widespread attention from researchers in the stem cell biology field. Yet, the molecular and cellular mechanisms that govern asymmetric stem cell division remain poorly understood. Stem cells are not the only cell population that divides asymmetrically, and fortunately, great progress has been...
متن کاملMechanisms of Asymmetric Stem Cell Division
Stem cells self-renew but also give rise to daughter cells that are committed to lineage-specific differentiation. To achieve this remarkable task, they can undergo an intrinsically asymmetric cell division whereby they segregate cell fate determinants into only one of the two daughter cells. Alternatively, they can orient their division plane so that only one of the two daughter cells maintain...
متن کاملAsymmetric stem cell division: lessons from Drosophila.
Asymmetric cell division is an important and conserved strategy in the generation of cellular diversity during animal development. Many of our insights into the underlying mechanisms of asymmetric cell division have been gained from Drosophila, including the establishment of polarity, orientation of mitotic spindles and segregation of cell fate determinants. Recent studies are also beginning to...
