The animal phylogeny of glutamate receptors indicates that vertebrate types do not account for all receptor classes originated during evolution, neither are they the pinnacle of a linear evolutive process.
TOR kinase guides the transition of plant stem cells from the dormant embryonic state to the active adult state by integrating light and metabolic signals.
A new morphological structure evolved through extreme changes in cell height requires novel connections to an extracellular matrix network, which predates the origin of structure.
Cells employ two strategies, adjusting both their cell cycle lengths and their growth rates in a size-dependent manner, to correct aberrations in cell size.
A robust fluorescence microscopy-based data acquisition and analysis framework affords the precise measurement of cell surface receptor affinities toward their cognate ligands and their densities in live cells/tissues.
In contrast to amniotes, zebrafish (ray-finned fish, teleost) centra are formed from specialised notochord sheath cells, and the segmental patterning of these cells is independent of the segmentation clock.
Biological shapes and morphological transitions can emerge from combining directed interactions between cells with apical-basal and planar cell polarity.
Quantitative analysis in quasi-3D reveals apically driven cell behaviours that are closely coordinated across the tissue to allow ordered tube invagination through a focal point.
Microtubules are nucleated by the centrosome of the primary cilium in the apical end-foot of neuroepithelial cells and inter-dependent microtubule and actin dynamics are required here to orchestrate delamination of newborn neurons.
