Cell fate diversity is generated in part by the unequal segregation of cell-fate determinants during asymmetric cell division. In the Drosophila bristle lineage, the sensory organ precursor (pI) cell is polarized along the anteroposterior (AP) axis by Frizzled (Fz) receptor signaling. We show here that Fz localizes at the posterior apical cortex of the pI cell prior to mitosis, whereas Strabism...

The majority of cells that build the nervous system of animals are generated early in embryonic development in a process called neurogenesis. Although the vertebrate nervous system is much more complex than that of insects, the underlying principles of neurogenesis are intriguingly similar. In both cases, neuronal cells are derived from polarized progenitor cells that divide asymmetrically. One...

Asymmetric localization is a prerequisite for inscuteable (insc) to function in coordinating and mediating asymmetric cell divisions in Drosophila. We show here that Partner of Inscuteable (Pins), a new component of asymmetric divisions, is required for Inscuteable to asymmetrically localize. In the absence of pins, Inscuteable becomes cytoplasmic and asymmetric divisions of neuroblasts and mit...

Sporulation in Bacillus subtilis requires asymmetric cell division, chromosome transfer into the spore and establishment of differential gene expression patterns. Several recent studies highlight the key roles of the SpoIIIE motor in this process.

Recent studies have found that Drosophila gene products required for zonula adherens formation in the ectoderm are also involved in the asymmetric cell division of the neuroblast. The results illustrate the reiterated use of groups of proteins to dictate cell polarity in epithelial and non-epithelial cells.

Asymmetric cell division is utilized by a broad range of cell types to generate two daughter cells with distinct cell fates. In stem cell populations asymmetric cell division is believed to be crucial for maintaining tissue homeostasis, failure of which can lead to tissue degeneration or hyperplasia/tumorigenesis. Asymmetric cell divisions also underlie cell fate diversification during developm...

Significance Studies on bacterial and eukaryotic viruses have revealed a range of strategies used by to subdue host cells for efficient virus replication. How archaeal interact with their hosts remains largely unknown. We characterize new strategy employed nonlytic STSV2 transform its into giant virion-producing factory, whereby the infection blocks normal cell division binary fission, leading ...

In this issue of Cell, Kidd and colleagues (Kidd et al., 2005) describe their identification of a novel beta-catenin that functions in noncanonical C. elegans Wnt signaling pathways to specify the different fates of daughter cells produced by asymmetric cell division.
