Transport efficiency of metachronal waves in 3d cilia arrays immersed in a two-phase flow

open access: yes, 2016
The present work reports the formation and the characterization of antipleptic and symplectic metachronal waves in 3D cilia arrays immersed in a two-fluid environment, with a viscosity ratio of 20.

The ductal network in the human testis and epididymis: What belongs to which?

open access: yesClinical Anatomy, EarlyView.
Abstract The testes and epididymis are traversed by a system of tubules in which sperm cells are generated, matured, nourished, and transported. Among these are the efferent ductules, which connect the rete testis to the duct of the epididymis. In the Terminologia Anatomica (TA), the efferent ductules are assigned to the testicles, while numerous ...

Cryo electron tomography with volta phase plate reveals novel structural foundations of the 96-nm axonemal repeat in the pathogen Trypanosoma brucei

open access: yeseLife, 2019
The 96-nm axonemal repeat includes dynein motors and accessory structures as the foundation for motility of eukaryotic flagella and cilia. However, high-resolution 3D axoneme structures are unavailable for organisms among the Excavates, which include ...

Structures and functions of cilia during vertebrate embryo development

open access: yesMolecular Reproduction and Development, Volume 89, Issue 12, Page 579-596, December 2022., 2022
Abstract Cilia are hair‐like structures that project from the surface of cells. In vertebrates, most cells have an immotile primary cilium that mediates cell signaling, and some specialized cells assemble one or multiple cilia that are motile and beat synchronously to move fluids in one direction.

The Role of Sperm Centrioles in Human Reproduction – The Known and the Unknown

open access: yesFrontiers in Cell and Developmental Biology, 2019
Each human spermatozoon contains two remodeled centrioles that it contributes to the zygote. There, the centrioles reconstitute a centrosome that assembles the sperm aster and participate in pronuclei migration and cleavage. Thus, centriole abnormalities

Active colloidal chains with cilia- and flagella-like motion [PDF]

open access: yesarXiv, 2018
It has been shown that self-assembled chains of active colloidal particles can present sustained oscillations. These oscillations are possible because of the effective diffusiophoretic forces that mediate the interactions of colloids do not respect the action--reaction principle and hence, a Hopf bifurcation is possible even for overdamped dynamics ...

Primary cilium loss in mammalian cells occurs predominantly by whole-cilium shedding

open access: yesPLOS Biology, 2019
The primary cilium is a central signaling hub in cell proliferation and differentiation and is built and disassembled every cell cycle in many animal cells. Disassembly is critically important, as misregulation or delay of cilia loss leads to cell cycle defects. The physical means by which cilia are lost are poorly understood but are thought to involve

The Heterotaxy Gene CCDC11 Is Important for Cytokinesis via RhoA Regulation

open access: yesCytoskeleton, EarlyView.
ABSTRACT Mutations in CCDC11 (cfap53) have been identified in multiple patients with heterotaxy (Htx), a disorder of left–right (LR) patterning of the internal organs. In Xenopus, depletion of Ccdc11 causes defects in LR patterning, recapitulating the patient phenotype. Upon Ccdc11 depletion, monociliated cells of the Left–Right Organizer (LRO) exhibit
