Mechanisms 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 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 کاملAsymmetric cell division requires specific mechanisms for adjusting global transcription
Most cells divide symmetrically into two approximately identical cells. There are many examples, however, of asymmetric cell division that can generate sibling cell size differences. Whereas physical asymmetric division mechanisms and cell fate consequences have been investigated, the specific problem caused by asymmetric division at the transcription level has not yet been addressed. In symmet...
متن کاملInductive asymmetric cell division
C. elegans, with its invariant cell lineage, provides a powerful model system in which to study signaling-dependent asymmetric cell division. The C. elegans β-catenin-related protein, WRM-1, specifies endoderm at the 4-cell stage during the first cell signaling-induced asymmetric cell division of embryogenesis. During this interaction, Wnt signaling and the cell cycle regulator CDK-1 act togeth...
متن کاملG Protein Signaling and Asymmetric Cell Division
Asymmetric cell division depends on the polarization of the dividing cell for the correct alignment of the mitotic spindle and the localization of cytoplasmic determinants. Receptor-independent activation of heterotrimeric G proteins by the Drosophila GoLoco protein Partner of Inscuteable seems to represent a novel mechanism to control these events.
