Fluid mechanics of mosaic ciliated tissues

  title={Fluid mechanics of mosaic ciliated tissues},
  author={Francesco Boselli and Jerome Jullien and Eric Lauga and Raymond E. Goldstein},
In tissues as diverse as amphibian skin and the human airway, the cilia that propel fluid are grouped in sparsely distributed multiciliated cells (MCCs). We investigate fluid transport in this “mosaic” architecture, with emphasis on the trade-offs that may have been responsible for its evolutionary selection. Live imaging of MCCs in embryos of the frog Xenopus laevis shows that cilia bundles behave as active vortices that produce a flow field accurately represented by a local force applied to… 
Cellular organization in lab-evolved and extant multicellular species obeys a maximum entropy law
The prevalence of multicellular organisms is due in part to their ability to form complex structures. How cells pack in these structures is a fundamental biophysical issue, underlying their


Using Xenopus skin to study cilia development and function.
Spatiotemporal organization of cilia drives multiscale mucus swirls in model human bronchial epithelium
This work reports on the existence of multiple ciliary domains with sizes ranging from the tens of a micron to the centimeter, where ciliary beats present a circular orientational order, associated with circular mucus flow patterns, whose size scales with the average cilia density.
Biofluidmechanics of Reproduction
This work examines sperm motility in the reproductive tract, ovum pickup and transport in the oviduct, as well as sperm-egg interactions, and outlines promising computational fluid dynamics frameworks that may be used to investigate these complex, fluid-structure interactions.
Entrainment of mammalian motile cilia in the brain with hydrodynamic forces
Significance We determine, in multiciliated mammalian cells, conditions for oscillatory flow to entrain brain motile cilia: Hydrodynamic forces of magnitude comparable to those generated by cilia
Green Algae as Model Organisms for Biological Fluid Dynamics.
This review summarizes recent developments in volvocine green algae and highlights promising future directions in the study of biological fluid dynamics, especially in the context of evolutionary biology, that can take advantage of these remarkable organisms.
Multi-scale spatial heterogeneity enhances particle clearance in airway ciliary arrays
Surprisingly, disorder enhances particle clearance, whether it originates from fluctuations, heterogeneity in multiciliated cell arrangement or ciliary misalignment, in a self-assembled biological system.
Polarity in Ciliate Models: From Cilia to Cell Architecture
How local polarities in basal bodies/cilia are regulated and transmitted through cell division in order to maintain the global polarity and shape of these cells and locally constrain the interpretation of signals by different cilia is discussed.
Active mucus–cilia hydrodynamic coupling drives self-organization of human bronchial epithelium
It is shown on polarized human bronchial epithelia that mucus swirls and circular orientational order of the underlying ciliary beats emerge and grow during ciliogenesis, until a macroscopic mucus transport is achieved for physiological ciliary densities.
Fluid Mechanics of Propulsion by Cilia and Flagella
This review restricts this review primarily to a summary of present understanding of the low-Reynolds-number flows associated with microorganism propulsion and the hydromechanics of ciliary systems.
Cilia-based flow network in the brain ventricles
A cilia-based transport network that suggests how cerebrospinal fluid constituents are actively distributed is revealed in the brain is revealed and suggests that ciliated epithelia can generate and maintain complex, spatiotemporally regulated flow networks.
