..., and is driven by cell intercalation, cell shape changes, and oriented cell divisions at the posterior germband. Anterior germband cells also divide during axis elongation. We developed image analysis and pattern-recognition methods to track dividing cells from confocal microscopy movies in a generally...

... remains largely unstudied. We unveil a non-classical role for the zebrafish hoxb1b gene, which shares ancestral functions with mammalian Hoxa1 , in controlling progenitor cell shape and oriented cell division during zebrafish anterior hindbrain neural tube morphogenesis. This is likely distinct from its...

... of collecting duct epithelium was the only cellular defect we found associated with the onset of the failure of renal medulla formation in Wnt7b mutants (E15.5), although apoptosis was elevated at a later stage (E17.5). This suggests that oriented cell division is one crucial parameter initiating...
