Through the interaction between PCP signaling and N-cadherin, oriented cell division and cell rearrangement are coordinated to establish the appropriate tissue architecture critical for limb skeletal morphogenesis.
Emx2 is not required for sibling HCs to acquire their designated locations within the neuromast, inferring that Emx2 mediates opposite HC orientation by changing location of hair bundle establishment.

A new approach measures the respective participations of elementary cell behaviors – such as cell division, intercalation, shape change and death – in the shaping of animal tissues.

Developmentally controlled chiral counter-rotating actomyosin flows drive cell-lineage spindle skews and cell rearrangements during cytokinesis in early nematode development.
TET methylcytosine oxidases cooperate with B lineage-specific transcription factors to promote immunoglobulin gene rearrangement by depositing 5hmC, facilitating DNA demethylation and increasing chromatin accessibility at enhancers.

Active and passive contributions to cell shape change and rearrangements can be distinguished from observed cell geometry, revealing the self-organization mechanisms underlying internally-driven epithelial convergent extension.
The B-1a cell heavy chain antibody repertoire differs dramatically from the follicular and marginal zone B cell repertoire and is defined by distinct mechanisms driven by self antigens rather than antigens derived from the microbiota.
