Cilia Action in Islets: Lessons From Mouse Models
Frontiers in Endocrinology, 2022 Primary cilia as a signaling organelle have garnered recent attention as a regulator of pancreatic islet function. These rod-like sensors exist on all major islet endocrine cell types and transduce a variety of external cues, while dysregulation of cilia

Microfluidic propulsion by the metachronal beating of magnetic artificial cilia: a numerical analysis [PDF]
, 2011 In this work we study the effect of metachronal waves on the flow created by magnetically-driven plate-like artificial cilia in microchannels using numerical simulations. The simulations are performed using a coupled magneto-mechanical solid-fluid computational model that captures the physical interactions between the fluid flow, ciliary deformation ...

Asymmetry in cilia configuration induces hydrodynamic phase locking [PDF]
Phys. Rev. E 97, 032411 (2018), 2017 To gain insight into the nature of biological synchronization at the microscopic scale, we here investigate the hydrodynamic synchronization between conically rotating objects termed nodal cilia. A mechanical model of three rotating cilia is proposed with consideration of variation in their shapes and geometrical arrangement.

Asymmetric motion of magnetically actuated artificial cilia [PDF]
Lab Chip, 2017,17, 3138-3145, 2018 Most microorganisms use hair-like cilia with asymmetric beating to perform vital bio-physical processes. In this paper, we demonstrate a novel fabrication method for creating magnetic artificial cilia capable of such biologically inspired asymmetrical beating pattern essential for creating microfluidic transport in low Reynolds number.

Mixing and transport by ciliary carpets: a numerical study [PDF]
Journal of Fluid Mechanics / Volume 743 / March 2014, pp 124 - 14, 2013 We use a 3D computational model to study the fluid transport and mixing due to the beating of an infinite array of cilia. In accord with recent experiments, we observe two distinct regions: a fluid transport region above the cilia and a fluid mixing region below the cilia tip.

Cells, 2022 Cilia are hair-like projections of the plasma membrane with an inner microtubule skeleton known as axoneme. Motile cilia and flagella beat to displace extracellular fluids, playing important roles in the airways and reproductive system.

Spontaneous creation of macroscopic flow and metachronal waves in an array of cilia [PDF]
, 2006 Cells or bacteria carrying cilia on their surface show many striking features : alignment of cilia in an array, two-phase asymmetric beating for each cilium, coordination between cilia and existence of metachronal waves with a constant phase difference between two adjacent cilia.

Advanced Functional Materials, EarlyView.Surface‐attached multilayer micromagnet systems are fabricated by two‐photon crosslinking. The pillar‐shaped micro actuators consist of a soft and flexible surface‐attached cell‐repellent hydrogel layer at the bottom, acting as a hinge and a cell‐adhesive hydrophobic polymer filled with magnetic nanoparticles.

Biofilm Control by Active Topography with Mucin Coating
Advanced Functional Materials, EarlyView.This study reports a new antifouling strategy based on a bioinspired design. Mucin coating enhances biofilm control by active topography with beating micron‐sized pillars. Besides the mechanical force of beating pillars, the antibiofilm activities also involve biological factors since mucin coating inhibits swarming motility and c‐di‐GMP synthesis in ...
