Cellular aspect ratio and cell division mechanics underlie the patterning of cell progeny in diverse mammalian epithelia. [PDF]

open access: yes, 2018
Cell division is essential to expand, shape, and replenish epithelia. In the adult small intestine, cells from a common progenitor intermix with other lineages, whereas cell progeny in many other epithelia form contiguous patches.

From In‐Silico Optimized Microfabrication to Experimental Validation: Engineering a Tridimensional Epi‐Intraneural Interface

open access: yesAdvanced Functional Materials, EarlyView.
An epi‐intraneural interface is developed through in silico optimization and a novel tridimensional microfabrication pipeline. The device integrates penetrating and epineural contacts on a flexible substrate. Mechanical, electrochemical, and in vivo testing in rat and pig reveal robust implantation, low‐threshold activation, and site‐dependent ...

PKCɛ switches Aurora B specificity to exit the abscission checkpoint

open access: yesNature Communications, 2016
The Aurora B abscission checkpoint is activated when DNA is retained in the cleavage furrow on completion of anaphase. Here the authors show that PKCɛ directly phosphorylates Aurora B triggering a switch in Aurora B substrate specificity to elicit ...

Septin Remodeling During Mammalian Cytokinesis

open access: yesFrontiers in Cell and Developmental Biology, 2021
Cytokinesis mediates the final separation of a mother cell into two daughter cells. Septins are recruited to the cleavage furrow at an early stage. During cytokinetic progression the septin cytoskeleton is constantly rearranged, ultimately leading to a ...

Cleavage furrow formation in a telolecithal egg (Loligo pealii). II. Direct evidence for a contraction of the cleavage furrow base [PDF]

open access: yesJournal of Experimental Zoology, 1971
AbstractCleavage of the highly telolecithal egg of a squid is meroblastic and stops when the base of each furrow cuts through the cytoplasm of the blastodisc and contacts the yolk. The base of each furrow is composed of a band of 50 Å filaments which apparently are linked to the surface membrane.

A Programmable Semiconductor Containing Active Molecular Photoswitches Located in the Crystal's Volume Phase

open access: yesAdvanced Functional Materials, EarlyView.
A novel approach for the design of functional semiconductors is presented, which utilizes the excellent optoelectronic properties of layered hybrid perovskites and the possibility to introduce a molecular photoswitch as the organic spacer. This concept is successfully demonstrated on a coumarin‐based system with the possibility to change the bandgap ...

A kinesin-13 family kinesin in Trypanosoma brucei regulates cytokinesis and cytoskeleton morphogenesis by promoting microtubule bundling.

open access: yesPLoS Pathogens
The early branching eukaryote Trypanosoma brucei divides uni-directionally along the longitudinal cell axis from the cell anterior toward the cell posterior, and the cleavage furrow ingresses along the cell division plane between the new and the old ...

HIPK2 and extrachromosomal histone H2B are separately recruited by Aurora-B for cytokinesis [PDF]

open access: yes, 2018
Cytokinesis, the final phase of cell division, is necessary to form two distinct daughter cells with correct distribution of genomic and cytoplasmic materials.

Mapping Nanoscale Buckling in Atomically Thin Cr2Ge2Te6

open access: yesAdvanced Functional Materials, EarlyView.
Atomic‐resolution STEM is used to resolve nanoscale buckling in monolayer Cr2Ge2Te₆. A noise‐robust image analysis reconstructs three‐dimensional lattice distortions from single plan‐view images, revealing pronounced defect‐driven nm‐scale out‐of‐plane buckling.

Possible origins of macroscopic left-right asymmetry in organisms

open access: yes, 2012
I consider the microscopic mechanisms by which a particular left-right (L/R) asymmetry is generated at the organism level from the microscopic handedness of cytoskeletal molecules.
