Enigmatic Nodal and Lefty gene repertoire discrepancy: Latent evolutionary history revealed by vertebrate‐wide phylogeny

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Homology in vertebrate body plans is traditionally ascribed to the high‐level conservation of regulatory components within the genetic programs governing them, particularly during the “phylotypic stage.” However, advancements in embryology and molecular phylogeny have unveiled the dynamic nature of gene repertoires responsible for early ...

Dynamic Changes in Ultrastructure of the Primary Cilium in Migrating Neuroblasts in the Postnatal Brain

open access: yesJournal of Neuroscience, 2019
New neurons, referred to as neuroblasts, are continuously generated in the ventricular-subventricular zone of the brain throughout an animal's life. These neuroblasts are characterized by their unique potential for proliferation, formation of chain-like ...

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 ...

BMP4 regulates asymmetric Pkd2 distribution in mouse nodal immotile cilia and ciliary mechanosensing required for left–right determination

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Mouse nodal immotile cilia mechanically sense the bending direction for left–right (L–R) determination and activate the left‐side‐specific signaling cascade, leading to increased Nodal activity. Asymmetric distribution of Pkd2, a crucial channel for L–R determination, on immotile cilia has been reported recently. However, the causal

Spatiotemporal distribution of neural crest cells in the common wall lizard Podarcis muralis

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Neural crest cells (NCCs) are migratory embryonic stem cells that give rise to a diverse set of cell types. Here we describe the dynamic distribution of NCCs in developing embryos of the common wall lizard Podarcis muralis inferred from 10 markers.

Primary cilia are required for the persistence of memory and stabilization of perineuronal nets

open access: yesiScience, 2021
Summary: It is well established that the formation of episodic memories requires multiple hippocampal mechanisms operating on different time scales.

Activation and inhibition of Notch signaling facilitate proliferative regeneration of sensory cells in adult mice

open access: yesEye &ENT Research, EarlyView.
Abstract Due to the limited regenerative capacity in adult mammals, the loss of vestibular hair cells (HCs) leads to balance disorders. In this study, we chronologically reprogrammed adult vestibular supporting cells (SCs) via bimodal regulation of Notch signaling, mimicking dynamic changes in Notch signaling during inner ear development. We found that
