Maintenance of cell type-specific connectivity and circuit function requires Tao kinase
Nature Communications, 2019 It is unclear how circuit specificity and function are maintained during organismal growth. In this study, authors show that connectivity between primary nociceptors and their downstream neurons scales with animal size and that Ste20-like kinase Tao acts

Synchronization of endothelial Dll4-Notch dynamics switch blood vessels from branching to expansion
eLife, 2016 Formation of a regularly branched blood vessel network is crucial in development and physiology. Here we show that the expression of the Notch ligand Dll4 fluctuates in individual endothelial cells within sprouting vessels in the mouse retina in vivo and

Interactive manipulation of microparticles in an octagonal sonotweezer [PDF]
, 2013 An ultrasonic device for micro-patterning and precision manipulation of micrometre-scale particles is demonstrated. The device is formed using eight piezoelectric transducers shaped into an octagonal cavity.

eLife, 2019 The cAMP-dependent protein kinase A (PKA) regulates various cellular functions in health and disease. In endothelial cells PKA activity promotes vessel maturation and limits tip cell formation.

Frontiers in Cell and Developmental Biology, 2021 Proper brain development requires precisely controlled phases of stem cell proliferation, lineage specification, differentiation, and migration. Lineage specification depends partly on concentration gradients of chemical cues called morphogens.

Patterned Nanomagnetic Films [PDF]
, 2006 Nano-fabrication technologies for realising patterned structures from thin films are reviewed. A classification is made to divide the patterning technologies in two groups namely with and without the use of masks. The more traditional methods as well as

Intrinsic noise profoundly alters the dynamics and steady state of morphogen-controlled bistable genetic switches [PDF]
, 2016 During tissue development, patterns of gene expression determine the spatial arrangement of cell types. In many cases, gradients of secreted signaling molecules - morphogens - guide this process.

RNA-Seq identifies SPGs as a ventral skeletal patterning cue in sea urchins [PDF]
, 2016 The sea urchin larval skeleton offers a simple model for formation of developmental patterns. The calcium carbonate skeleton is secreted by primary mesenchyme cells (PMCs) in response to largely unknown patterning cues expressed by the ectoderm.

The transcription factors BEL1 and SPL are required for cytokinin and auxin signaling during ovule development in Arabidopsis [PDF]
, 2012 Hormones, such as auxin and cytokinin, are involved in the complex molecular network that regulates the coordinated development of plant organs. Genes controlling ovule patterning have been identified and studied in detail; however, the roles of auxin ...
