Recent work has revealed an evolutionarily conserved trio of proteins that regulate cell polarity in epithelial cells, embryonic blastomeres and neural precursors. This common cell-polarity mechanism ...

In most flowering plants, the asymmetric cell division of the zygote is the initial step in establishing the apical–basal axis of the mature plant. The zygote is polarized, possessing the nucleus at ...

In both worms and flies, asymmetric cell divisions involve the protein Bazooka/PAR-3, which is required for the asymmetric segregation of cell-fate determinants. However, differential distribution of ...

The primordial germ cells (PGCs) of a recently metamorphosed juvenile Synaptula hydriformis occur with somatic cells in the germinal epithelium of the gonad. As part of the epithelium, PGCs rest on a ...

Below is a guide on how to choose the appropriate markers to label neuroepithelial cells. The neural plate and the neural tube, during embryonic development, are formed by neuroepithelial (NE) cells ...
