Bioengineering, 2022 There is a lack of physiologically relevant in vitro human kidney models for disease modelling and detecting drug-induced effects given the limited choice of cells and difficulty implementing quasi-physiological culture conditions.

Elastohydrodynamic phase-lock in two rotating cilia
Journal of Biomechanical Science and Engineering, 2017 Determination of left-right asymmetry of the body plan is achieved in the early embryo. At the 4-6 somite stage, a cavity structure, called a node, is observed in the ventral midline surface, in which hundreds of cilia rotate.

Energetics of synchronisation for model flagella and cilia [PDF]
Phys. Rev. E 103, 042419 (2021), 2021 Synchronisation is often observed in the swimming of flagellated cells, either for multiple appendages on the same organism or between the flagella of nearby cells. Beating cilia are also seen to synchronise their dynamics. In 1951, Taylor showed that the observed in-phase beating of the flagella of co-swimming spermatozoa was consistent with ...

Shape-programmable artificial cilia for microfluidics
iScience, 2021 Summary: The artificial ciliary motion has been known not to be hydrodynamically optimal, limiting their associated applications in the microscale flow domain.

Ependymal cilia beating induces an actin network to protect centrioles against shear stress
Nature Communications, 2018 Ependymal ciliary beating contributes to the flow of cerebrospinal fluid in the brain ventricles and these cilia resist the flow forces. Here the authors show that the assembly of a dense actin network around the centrioles is induced by cilia beating to

Role of spatial heterogeneity on the collective dynamics of cilia beating in a minimal 1D model [PDF]
Phys. Rev. E 97, 012403 (2018), 2017 Cilia are elastic hairlike protuberances of the cell membrane found in various unicellular organisms and in several tissues of most living organisms. In some tissues such as the airway tissues of the lung, the coordinated beating of cilia induce a fluid flow of crucial importance as it allows the continuous cleaning of our bronchia, known as ...

Evaluating efficiency and robustness in cilia design [PDF]
Phys. Rev. E 93, 033119 (2016), 2015 Motile cilia are used by many eukaryotic cells to transport flow. Cilia-driven flows are important to many physiological functions, yet a deep understanding of the interplay between the mechanical structure of cilia and their physiological functions in healthy and diseased conditions remains elusive.

Rebuilding ships while at sea—Character individuality, homology, and evolutionary innovation
Journal of Morphology, Volume 284, Issue 1, January 2023., 2023 Building on a previous account of evolutionary innovation, I propose here that evolutionary novelties are those individualized characters that are not homologous to any characters in the ancestor. Integrating functional and structural perspectives, I argue that functional as well as structural considerations are important for character ...

MHD compressible fluid with variable thermal conductivity through a ciliated channel
Advances in Mechanical Engineering, 2021 This paper employs to discuss the cilia induced flow of a compressible Jeffrey fluid with variable characteristic of thermal conductivity. Thermal conductivity is thermally variable. Effects of thermal radiation and MHD are also explored.
