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.

The RAB-28 GTPase regulates ciliary extracellular vesicle shedding, which may be important for neuron-glia communication.

A distinct resident macrophage subpopulation that localizes to the adipose stroma and fibrous capsule of the nulliparous mammary gland and to extracellular matrix-enriched stroma surrounding mammary tumors is identified.

Action potentials propagating in axon bundles with bifurcating and terminating fibers cause strong and far-reaching extracellular potentials.

Comparison of the intracellular activity of hippocampal neurons in novel and familiar environments reveals experience-dependent changes in inputs underlying the formation of stable representations of space.

Analysis of iconic and gating currents of wild type and mutated BK channels reveals a strong inhibition of this channel by extracellular acidification and elucidates the underlying mechanism that is potentially applicable to other voltage-dependent cation channels.

Different cytoneme types require specific heparan sulfate proteoglycans (HSPGs) that are stratified within the extracellular matrix in Drosophila.

Automated segmentation of neurons and identification of synapses in electron micrographs is significantly improved by using simple modifications to chemical fixation protocols that preserve extracellular space in the brain.

Hybrid-type fluorescent ATP sensor showing submicromolar affinity, a large fluorescence response, high selectivity and pH-independence visualized extracellular ATP dynamics in the brain of living mice with high spatiotemporal resolution.

Biochemical fractionation of vesicle sub-populations and in vitro reconstitution studies reveal that Lupus La protein mediates the selective sorting of miR-122 into extracellular vesicles in vitro and in vivo.
